Reliability & Maintenance of Solar or Wind renewable energy systems Research Paper - 1

Reliability & Maintenance of Solar or Wind renewable energy systems - Research Paper Example Every failure has a cost attached to it. The principal reliability-linked factors of cost through the useful life of an item being Design & Development, Production and Maintenance & Repair, evaluated in the backdrop of installation and environmental parameters like temperature, humidity, vibration, corrosion by chemical attack etc. and the degradation caused by the combination of a few or all of them. A higher reliability invariably envisages higher production, design and development costs, whereas, appropriately factored-in maintenance and repair costs can lead to higher levels of reliability. In the context of non-sustainability of the current energy practices, dawning of global awareness that renewable energy sources are the only way out, has led to a sensible emphasis on solar energy as one of the (wind energy being the other) most abundant and attractive renewable energy source, easily available for harnessing. In the scenario of rapidly depleting natural energy sources like coa l, oil and natural gas, the solar option has presented itself as an alternative which is being vigorously pursued for viability for commercial exploitation in the longer run. A system that uses solar cells and solar panels in a mechanical system that collects, transforms DC current into AC current and stores the electricity for later use is often called Active Solar Energy. The deeper â€Å"Bath Tub† assumes the shape of a â€Å"Shallow Pan† in the case of static equipments predominantly deployed for renewable energy applications, as far as reliability is concerned; the failure zones in this case are therefore not pronounced. Listed below are a few indicative amongst the many, though not exhaustive, but popular applications: Solar air conditioning Solar ovens for heating of foodstuffs Agricultural irrigation Hydrogen generation by the use of photo-electro-chemical cells The following applications however stand out amongst the most popular commercial applications: 1. Ge neration of electricity in Solar updraft towers Solar towers use an array of reflectors termed ‘heliostats’, approximately 120 sq. meters in size. Located on top of 150 meters tall towers within receptacles, these are directed towards the sun for direct absorption of the heat of the concentrated solar radiation. Operating temperatures close to 1000oC can be attained depending upon the choice of the heat transfer fluid (HTF) which in turn also decides the design of the receptacle, lined with the very best quality insulation material for optimum performance. High reliability is foreseen at the design stage itself. Likely failure points are identified in advance using the FMECA (Failure Mode Criticality and Effect Analysis) technique and appropriate specification de-rating vis-a-vis the liberal vendor rating is resorted to, for ensuring realistic unhindered performance. Finite element thermal simulation and sensitivity analysis to comply with the thermal specifications als o forms part of the internal product review. External third party assessment provides inputs for MTBF (Mean Time between Failures) calculation for useful lifetime assessment, maintainability and manufacturing as part of an iterative design process for consistent improvement of product designs and individual components. Selection of the most appropriate materials of construction of all the components of solar renewable energy systems forms the last

No matter how hard it is, as long as you stay persistent and self determined you will overcome those obstacles. There were so many stages on my risky challenge journey to find a happy life! To know who you are you must know where you began. My life starts in a small village in Viet Nam. Despite growing up with a privilege life full of food on the table, a warm bed to sleep in, plenty of toys†¦It is human nature to want what I don’t have-nurturing parents. My parents worked very hard to provide a better life that they never had. I and three of my brothers were grown up with unhappy childhood. We never had time to play with friends, go to the park or even get any gift on our birthday †¦.All of us had to work after school to help my parents earn more money for food and others basic shelters. When I was in the middle school I had to do all of the housework and trading in the market for foods. I believed that is why I am so independent on my life. MY name is â€Å"My† which is often misspelled and misunderstanding. But it carried a full meaning to my parents. First it means beautiful. Second it links to a country â€Å"United State of American†. When I was a kid my parents usually tell me about how wonderful American are which in . Wealthy, Independence and freedom In 1987 when I was born my parents escaped from Vietnam to United State of American to explore a new life with a standard living but they failed and I was named â€Å"My† to chase my parents dream. I and my Parents had shared about â€Å"American dream† since I was 10 years old. I always dreamed of get out of my small village to fulfill my family dream and make a better life to help my parents who had sacrifice themselves to raise us to become good persons. Even how hard they are we still go through school. I was always study very hard at school and look for a chance to study aboard in the promising land American. Time went by and even how hard my parents and I tried we still could not afford for going aboard. But I still kept thinking about this dream until one day I had got a chance to take risk to work aboard as a technician specialist named Chartered Semiconductor in Singapore. The day I left my country and my family was a gloomiest day that I never forget. I was very excited to explore about Singapore at the first time I came there. I heard that Singapore is a very high standard country. Living and working in this country I don’t have to suffer from any obstacle. But dream is always dream and when I started to work I knew that it is never easy to get what you want without skills and experiences. Things never come the way I expected. It s so much can be say for living and immersing myself in another country and multicultural. I had to face with a lot of horrible experiences at work. Especially it was so difficult for me to adjust to speak Sing-English. Co-worker made fun of my English. I was hurt like a deep wound cut inside. I was cried some nights and even I was mad at myself. But 2 weeks later I told myself not to be discouraged because I left my homeland for this and there was no excuse for me to give up. Slowly I tried to join at work, make friends and ask them whatever I didn’t understand. I found my own way to get help. I gradually created my life with a fully eye-open experience.

Blade Runner: A Post Modern Dystopia?

Blade Runner: A Post Modern Dystopia? Utopias and Dystopias To what extent can Blade Runner be considered to be a prime example of a post-modern dystopia? What is Dystopia? First to define dystopia, you need to know what is utopia. In 1551 Thomas More published the first English description of a fiction based on the ideal society with economic stability and harmonious political system. Mores Utopia was that of a society where no one owned property citizens simply had the right to move wherever they wanted, everyone was to wear the same clothes there was no jealousy or envy of ones social status or wealth. No one lived in poverty, there was no hunger or violence to More and many it was the ideal world. The word Utopia comes from the Greek meaning no place and good place in Latin. Interestingly Mores utopia had slaved labour along with intense social control limiting freedom for individuals. So, what is dystopia and dystopian fiction? Dystopias are the complete opposite of utopia, with societies living imperfect, with extreme surveillance, social control, propaganda and paranoia. The term dystopia first came around in the nineteenth century by English philosopher John Stewart Mill in 1868. But it wasnt until the twentieth century and after world war two that the term became popular in novels and films. Dystopian fiction focuses on political and cultural issues George Orwells 1984 one of the most iconic dystopian novels write after world war two in 1949. This was a time of a totalitarian society such as the Nazi Germany and Soviet Union, Orwell implemented the thought police and big brother gaining complete control over citizens and their thoughts. The frightening element of dystopias is they are almost always relevant to current world affairs highlighting the dangers of what could happen given the circumstances. Dystopian fiction always portrays cultural and political sources such as; totalitarian, growing awarene ss of environmental damage, technology rapidly enhancing, surveillance, television, human engineering. Blade Runner (1982) The highly influential bleak dystopian view on the future the film Blade Runner was realised in 1982 it became one of the most popular dystopian science fiction films, it is based on a 1968 science fiction novel Do Androids dream of electric sheep? by Phillip K. Dick. Blade Runner displays a post-apocalyptic setting after a nuclear war with its focus on the dystopian urban environment. Blade Runner is interlinked with cyberpunk, displaying environmental collapse and technological evolution. The feel is claustrophobic throughout the film its enclosed dark, rainy and gloomy, the multicultural streets are heavily dominated by the Asian culture portraying a scene underclass. Everyone who could afford to the rich have gone to live off world with the rest left to get by economically less fortunate. Most of the films animals are extinct or endangered due to radiation, only the rich can afford to have animals. The plot focuses on the protagonist Rick Deckard, a bounty hunter with the task of eliminating six nexus androids, the androids Rick has to dismiss are almost identical to humans. It is considered to be a neo-noir film with its use of Deckard being antihero, the crime setting and also Rachel the femme fatale. The future of Los Angeles scene of decay and decline, the coming to the end of humanity with synthetic people that feel human striving for an extension to their lifespan. The film also includes aspects of modern urbanisation, globalisation and bio-engineering. Blade Runner didnt do particularly well at the box office on its first release in 1982, but has since become a huge critical success as a classic dystopian science fiction. There is a range of literature on Blade Runner in books and on websites, it is often highlighted as a postmodern film. In the Original Blade Runner, the director realised the film with a noir voice-over with futuristic, dystopian images where is time manipulated as a 1950s film displaced into the future although the shadows and constant rain fit in with the film-noir style. Blade Runner wants the audience to believe it is set in 2019, although evidence suggests its in the past,ÂÂ   with eighties clothes, music and haircuts. The questions the film asks is what is the meaning of humanity in the postmodern age, when the distinction between human and machine is unclear. Can emotions be programmed or humanity manufactured, these are the same questions postmodern philosophers ask; how we come to terms with the world when the image overrides the individual. Blade Runners Los Angeles has been compared to a postmodern city with its huge advertising promoting off world colony with the idea that the rich have fled to a better equivalent. Postmodernism is a period in cultural history, just as romanticism was. Modern culture, modernism in the early twentieth century this was a very powerful movement, before the first world war there was the idea that technology was bringing a better future after the first world war this idea collapsed technology made weapons for war especially during the holocaust the idea was that technology is not the best way to the perfect world. Postmodern culture is typically defined by characteristics; Technology, In particular technological development in relation to genetics, nuclear power and all aspects of information technology. Post modernism is associated with dominant emotions in postmodern cinema, literature and art, there are certain recurrent emotions such as paranoia. There is a sense of disorientation, alienation, disconnect a sense of being in outer space. Characters are emotional cripples, with no authentic emotions, no real feeling, artificial, fake postmodern culture explores the idea of artificial human engineering as more desirable than the real natural being. Film noir has a very strong influenced throughout the film, the constant rain, darkness, shadows and crime that being said the film also interoperates textual varieties a mixture of genres; science fiction, bioengineering, cyber-punk fiction and 1940s noir. Time travel is a big characteristic, travelling back and forwards in time and memory distortion. Post humanism the idea that human beings are technological enhanced and improved these characteristics can be found in Blade Runner. One of the defining movements of post modernism is the hope for a better future, a utopia, that fails and leaves you with a deep sense of pessimism of disorientation, a sense of deep uncertainty. Critics argue whether Blade Runner is a prime example of a postmodern film, Baudrillard states that Another film often cited as postmodern is Ridley Scotts Blade Runner (1982), in which science, technology and progress are all questioned and shown in some way to have failed. The world in Blade Runner is polluted by industry and overcrowding: only the rich escape to the off-worlds. One of the key themes of the film is the blurring of the differences between the real and the artificial, between the humans and the replicants. Increasingly it is no longer possible to be clear about what it means to be human. Nick Lacey, argues that Blade Runner isnt in fact postmodern and that director Ridley Scott shied away from the postmodern view of the world.ÂÂ   Blade Runner a production of mainstream cinema only films with an independent sensibility are able to fully represent the disturbing post human this is because the ideals of romantic love are central to patriarchal societys needs. (Lacey 2005) Lacey believes Blade Runner fails to portray a postmodern view of the human condition with the films scenes of the Tyrell buildings then shots of filthy streets below, it exposes the anger towards the upper class the better off citizens able to live off world. With Blade Runner being set in 2019, but strong evidence of the past is typical of postmodern films warning the audience the dangers of the future. Blade Runner explores future ideas where the fake becomes real, cars fly, scientists plant memories into machines etc. the examples of the fake becoming real and dangerous replicants escaping to earth portray post modernism into the future. Some themes in Blade Runner adhere to the orthodox dystopian cinema genre, the representation of romance conforms to gender stereotypes. Blade Runner uses the symbol of an owl as women, the role of women in the film are played by three lead females. The women are exposed as being products that can be sold or bought, a product, model of pleasure. Douglass E. Williams notes how the noir film elements in Blade Runner follow the same gender hierarchies of the 1940s distinguishing females into two categories, one sexual and treacherous, the other chaste and good. (Williams, 1988 pg390) its an example of modernity transferred into post modernity on the description of women. Blade Runner highlights a message that the future is hopeless. Marking a new age showing its dystopian end postmodernism flows throughout the film the gloomy dark rain and moody atmosphere. Rapidly enhanced technology but appears outdated. The film projects what chaos can be instilled when people reject the modern period. It displays the future as well as holding onto the past creating post industrialism. Begley Varun, wrote an academic journal on Blade Runner as a postmodern, Varun writes of evident criticism in Blade Runner, particularly its problematic encounter with postmodernism.ÂÂ   In hindsight, this encounter testifies to fundamental ambiguities in the postmodern enterprise, ambiguities with significant social and political implications. I will argue that postmodern accounts of Blade Runner depend on a series of strategic exclusions. Such accounts effectively displace not only modernist readings of the film, but also questions of narration, genre, popularity, and the specificity of the film medium. Lost amid the theoretical battlefield of the modern and postmodern are the films material and ideological contexts; Blade Runners cultural intelligibility is blurred by the modern/ postmodern exchange. This critical impasse underscores the troubled politics of postmodernism as if confronts commercial narrative and other forms of popular culture. Roughly speaking, critical responses to Blade Runner fall on either side of a modern/postmodern line. Postmodernist accounts diametrically oppose reading strategies dependant on conventional aesthetic notions (narrative, character, structure, reference, metaphor, symbol, etc.) that collectively we might term modernist. These two approaches entail radically different positions on the nature and function of interpretation. Modernist readings presuppose this films structural and semiotic depth, in stark contrast to the postmodernist emphasis on its surfaces. Some modernist interpretations discern utopian fantasies of redemption and transcendence embedded in the films apocalyptic veneer, A postmodernist approach, by contrast, emphasises the films resistance to the interpretive impulse, its voiding of symbolic, utopian and narrative meaning. The depthless postmodern surface incorporates fragments of once-meaningful codes and conventions that are now blankly cited without context or refere nt. The result is not a coherent aesthetic structure but an opaque and resistant pastiche. (B. Varun 2004) In Blade Runner, the postmodern aesthetic in the plots set design, effects, dialogue and language have been explored by many theorists.

No Child Left Behind Act :: essays research papers

Proposal   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The No Child Left Behind Act, a federal social program that tries to encourages after school programs should be eliminated and the extra funds given to schools to decide where it goes.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The NCLB Act, â€Å"was designed to improve education and achievement in America’s schools in four clearly defined ways: accountability for results, an emphasis on doing what works based on scientific research, expanded parental options and expanded local control flexibility.† Basically the Federal government funds schools for after-school programs to try to encourage school participation among students and reduce dropping out of school. Examples of after-school programs funded by the NCLB act are first and foremost tutoring, then extra-curricular activities such as sports, community service etc. Problems/need   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The NCLB Act is not effective because of the current situation of state governments calling certain schools â€Å"failures† because of their low exam scores, thereby reducing funding to the school. If the federal government is funding the NCLB Act for after school programs, it would seem that it was funding a non-effective program. I have broken down the consequences as follows.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  -Low test scores, school gets reduced funding and   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  put â€Å"under state review.†   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  -Teachers fired, less motive for students to stay   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  in school. School’s curriculum is ineffective.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  -Meaning more money would have to be spent on the   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  NCLB Act for it to compensate the loss of the   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  school’s own after-school programs.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  -So failing a school, based on government   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  standards, just to spend more on it? Digging   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  their own trap hole. Policy Proposals Based on my understanding of the education that I have received and the changes that I have witnessed, there are many alternatives to the NCLB Act, some of which I shall explain below. -Focus on strengthening the curriculum. Subjects should help student in the future. Introduction of GE courses in high school, instead of introducing GE courses in college.

Walmart Foreign Expansion Case Study

Wal-Mart’s Foreign Expansion Wal-Mart is the world’s largest retailer with tons of advantage above all the rest. It is very possible that this big time retailer can translate its merchandising strategy wholesale to another country and be highly successful at it (L. Hill, 2011, p. 167). The key to this method is being able to understand the culture and environment that it would need to transition it methods to. Take for instance what was read in the case about China. China originally turned its nose up at the Americanized way that Wal-Mart presented itself when first opened in 2006.The Chinese culture didn’t agree with meat being sold in Styrofoam or selling of dead fish. It’s their cultural preference to purchase food very freshly. So, Wal-Mart adapted to the surrounding culture. Wal-Mart was successful in Mexico because they hired local managers that were well versed in the Mexican culture and allowing them to control the merchandising strategy as they se e fit. Adaption is the key to survival is different environments and economies. With Mexico being a place of few vehicles for transportation, building smaller, closer stores was another huge benefit of it being successful in Mexican culture.When the huge retailer made steps to expand to South Korea and Germany with very little success, there was a realization made in regards to diversity and what Wal-Mart offered. Britain, Germany, and South Korea cultures have a preference of high end and higher-quality merchandise than what was offered by Wal-Mart. The low price strategy is practically unwarranted in a place to where paying more is accepted. The key difference between these countries and Mexico is that Mexico accepts the low price strategy.Wal-Mart is succeeding in China and to continue to do so they need maintain adapting to the Chinese culture way. They are definitely on track with being successful in China. Wal-Mart is considered to be a force within the marketplace (Orgel, 201 1). With the business continuing to adapt and expand throughout different nations, it’s very possible that in the future Wal-Mart will cause changes within the culture of different nations. It shouldn’t be the company’s goal to ultimately change the culture of the nation it expands to.However, it should focus on broadening the horizon and combine the low price strategy with the nation’s culture to be an innovation on the marketplace.

Mr Murder

Mr Murder As of right now in my story, Marty was uncuffed by the Police. He was uncuffed because his wife, Paige, identified her husband and told the police that they have the wrong man. Paige called them. Paige called them because Marty told her to call them from the Delorio's home because he had shot the "other."‚  The other is an assassin who is searching for a life. He was used to being programmed by his superiors and they had him trained. The other has killed a whore, a cashier, husband, and a wife. He murdered the husband and wife because he was programmed to. He murdered the cashier, because he realized the $300 that he has in his wallet wouldn't get him anywhere. He murders the whore because after having sex with her he feels as if he has been weak and has not lived up to his potential. After murdering all of these people he realizes that he needs a life and wants to search for it.Marty Reisman c early 1950s on the cover of his au...

The Killer Angeles essays

The Killer Angeles essays In the book The Killer Angeles, had great in depth detail about the civil war. And the turning point in the civil warm, Gettysburg. The site which claimed as many American lives as the whole Vietnam war put together. A war site that still is admired today. There were many great leaders in the battle of Gettysburg. One commander in the book that I admired was Joshua Chamberlain. He was a man that cared about his men. And was grateful of the men that severed in his command. He fought on the Union side. Another reason I have a lot of respect for Chamberlain is that he fought with his men during battle. For him to do that made his men fight harder for him. He had a lot of real emotions that his men could respect. He told the truth. He was a brave man that was well educated and had a good heart toward his men that fought with him. George Pickett was a man that I wasnt particularly found of. He wasnt a well strategic commander. He was a stubborn man that lead many men to their deaths. He had no battles in the civil war that could put him in the list of top commanders in history. The quote by Louie Amistead and Longstreet is stating how the civil war is a holy war. How ones beliefs go against anothers. How the war has more than moral belief. That this war is about what is their god given right. How no matter what you do killing people is not the answer. That war will not lead to no were in converting people into your beliefs and how to think. Now was the civil war a Holy War. It wasnt a war about religion and what religion is right. It was a war that was about preserving the Union. In some eyes it was a Holy War . The war was based on a one belief system against another belief system. But the civil war was more of a political war. The role of slavery in this book wasnt much of an issue. Although the south would say they wouldnt fight for any blacks. But the north w ...

Battle of Gallipoli in World War I

Battle of Gallipoli in World War I The Battle of Gallipoli was fought during World War I (1914-1918) and represented an attempt to knock the Ottoman Empire out of the war. The plan for the operation was conceived by First Lord of the Admiralty Winston Churchill who believed warships could force the Dardanelles and strike directly at Constantinople. When this proved unfeasible, the Allies elected to land troops on the Gallipoli Peninsula to open the straits. The early stages of the campaign were badly handled and Allied forces were effectively trapped in their beachheads. Though the Allies spent much of 1915 trying to breakout, they were not successful and the decision was made to withdraw late that year. The campaign marked the Ottoman Empires greatest victory of the war.

Using the ships of the Royal Navy, Churchill believed, partially due to faulty intelligence, that the straits could be forced, opening the way for a direct assault on Constantinople. This plan was approved and several of the Royal Navys older battleships were transferred to the Mediterranean. On the Offensive Operations against the Dardanelles began on February 19, 1915, with British ships under Admiral Sir Sackville Carden bombarding Turkish defenses with little effect. A second attack was made on the 25th which succeeded in forcing the Turks to fall back to their second line of defenses. Entering the straits, British warships engaged the Turks again on March 1, however, their minesweepers were prevented from clearing the channel due to heavy fire. Another attempt to remove the mines failed on the 13th, leading Carden to resign. His replacement, Rear Admiral John de Robeck, launched a massive assault on Turkish defenses on the 18th. This failed and resulted in the sinking of two old British and one French battleships after they struck mines. General Sir Ian Hamilton, 1910. Library of Congress Ground Forces With the failure of the naval campaign, it became clear to Allied leaders that a ground force was going to be needed to eliminate the Turkish artillery on the Gallipoli Peninsula which commanded the straits. This mission was delegated to General Sir Ian Hamilton and the Mediterranean Expeditionary Force. This command included the newly formed Australia and New Zealand Army Corps (ANZAC), the 29th Division, the Royal Naval Division, and the French Oriental Expeditionary Corps. Security for the operation was lax and the Turks spent six weeks preparing for the anticipated assault. Ottoman machine gun team during the Gallipoli Campaign. Bundesarchiv, Bild 183-S29571 / CC-BY-SA 3.0 Opposing the Allies was the Turkish 5th Army commanded by General Otto Liman von Sanders, the German advisor to the Ottoman army. Hamiltons plan called for landings at Cape Helles, near the tip of the peninsula, with the ANZACs landing further up the Aegean coast just north of Gaba Tepe. While the 29th Division was to advance north to take the forts along the straits, the ANZACs were to cut across the peninsula to prevent the retreat or reinforcement of the Turkish defenders. The first landings began on April 25, 1915, and were badly mismanaged (Map). Meeting stiff resistance at Cape Helles, British troops took heavy casualties as they landed and, after heavy fighting, were finally able to overwhelm the defenders. To the north, the ANZACs faired slightly better, though they missed their intended landing beaches by about a mile. Pushing inland from Anzac Cove, they were able to gain a shallow foothold. Two days later, Turkish troops under Mustafa Kemal attempted to drive the ANZACs back into the sea but were defeated by tenacious defending and naval gunfire. At Helles, Hamilton, now supported by French troops, pushed north towards the village of Krithia. Trench Warfare Attacking on April 28, Hamiltons men were unable to take the village. With his advance stalled in the face of determined resistance, the front began to mirror the trench warfare of France. Another attempt was made to take Krithia on May 6. Pushing hard, Allied forces only gained a quarter mile while suffering heavy casualties. At Anzac Cove, Kemal launched a massive counterattack on May 19. Unable to throw the ANZACs back, he suffered over 10,000 casualties in the attempt. On June 4, a final attempt was made against Krithia with no success. Gridlock After a limited victory at Gully Ravine in late June, Hamilton accepted that the Helles front had become a stalemate. Seeking to move around the Turkish lines, Hamilton re-embarked two divisions and had them landed at Sulva Bay, just north of Anzac Cove, on August 6. This was supported by diversionary attacks at Anzac and Helles. Coming ashore, Lt. General Sir Frederick Stopfords men moved too slowly and the Turks were able to occupy the heights overlooking their position. As a result, the British troops were quickly locked into their beachhead. In the supporting action to the south, the ANZACs were able to win a rare victory at Lone Pine, though their main assaults on Chunuk Bair and Hill 971 failed. Soldiers of the Royal Irish Fusiliers in the trenches on the southern section of Gallipoli Peninsula during World War I. Australian War Memorial On August 21, Hamilton attempted to revive the offensive at Sulva Bay with attacks on Scimitar Hill and Hill 60. Fighting in brutal heat, these were beaten off and by the 29th the battle had ended. With the failure of Hamiltons August Offensive, fighting calmed as British leaders debated the future of the campaign. In October, Hamilton was replaced by Lt. General Sir Charles Monro. After reviewing his command, and influenced by the entry of Bulgaria into the war on the side of the Central Powers, Monro recommended evacuating Gallipoli. Following a visit from Secretary of State for War Lord Kitchener, Monros evacuation plan was approved. Beginning on December 7, troop levels were drawn down with those at Sulva Bay and Anzac Cove departing first. The last Allied forces departed Gallipoli on January 9, 1916, when the final troops embarked at Helles. Aftermath The Gallipoli Campaign cost the Allies 187,959 killed and wounded and the Turks 161,828. Gallipoli proved to be the Turks greatest victory of the war. In London, the campaigns failure led to the demotion of Winston Churchill and contributed to the collapse of Prime Minister H. H. Asquiths government. The fighting at Gallipoli proved a galvanizing national experience for Australia and New Zealand, which had not previously fought in a major conflict. As a result, the anniversary of the landings, April 25, is celebrated as ANZAC Day and is both nations most significant day of military remembrance.

Use of Business Intelligence in Knowledge Management, Sales Essay

Use of Business Intelligence in Knowledge Management, Sales Forecasting or Market Research - Essay Example In order to demonstrate the variations in its meaning only two of its various meanings are demonstrated as under. â€Å"Business intelligence (BI) is a broad category of application programs and technologies for gathering, storing, analyzing, and providing access to data to help enterprise users make better business decisions. BI applications include the activities of decision support, query and reporting, online analytical processing (OLAP), statistical analysis, forecasting, and data mining.† (Sauder, 2011) and, â€Å"Normally describes the result of in-depth analysis of detailed business data. Includes database and application technologies, as well as analysis practices. Sometimes used synonymously with "decision support," though business intelligence is technically much broader, potentially encompassing knowledge management, enterprise resource planning, and data mining, among other practices. ...† (csumb, 2011) Trying to interpret the actual meanings of the term ‘intelligence’ and how it is evolved would give us a better understanding into the terminology of business intelligence itself. Generally, intelligence refers to the ability to understand, learn and evolve. Intelligence develops with every learning experience and input of every kind of information. Basic intelligence, when deployed in business environment is referred to as business intelligence. THE DISCUSSION: The capacity of human beings to incorporate prior instinctive and experience based knowledge to execute processes in order to achieve a particular objective is termed as intelligence. It’s a virtual entity that encompasses all logical horizons. Business is also one of the natural and logical processes. Logic can be defined as a set of rules that governs executions. To discriminate a process as being logical or illogical one needs to be intelligent. This new perspective about intelligence gives a much unde rstandable definition of Business Intelligence. BI would now be defined as, the capacity that enables businessmen to differentiate logical and illogical executions in a business.. This definition presents Business Intelligence as an umbrella that covers almost all the tasks performed under the tag of ‘businesses’. This paper emphasizes on the same notion with the discussion of multiple top notch business terms namely sales forecasting, market research and knowledge management. The association of business intelligence with sales forecasting, knowledge management and Market Research brings new meanings to this seemingly simple business term. It is attempted to take a general look at the basic definitions of each of the above mentioned terms before looking at their comparative involvements and meanings. SALES FORECASTING: Sales forecasting is a well known business terminology. Integral to its existence this business process involves an insight into the future prospects of a company’s sales. These sales may be spanned over any specific amount of time may it be weekly, monthly or yearly. The importance of this vital business process can be assessed by the fact that the prospective production strategies and those involving inventory are all based upon the feedback given to the business by it sales forecasting process. It is impossible that without having an idea of the sales of a business the designing of its inventory be done. Estimates regarding

Avoiding Data Manipulation when Sampling Essay Example | Topics and Well Written Essays - 500 words

Avoiding Data Manipulation when Sampling - Essay Example One of the important features in avoiding data manipulation when sampling is to be aware of the imperfections in the survey. There are an infinite number of means by which sampling exhibits imperfect features, and indeed, the idea of a perfect sample is a misnomer. Edwards (2010) indicates that even the color of a survey can alter sampling response. There are a variety of specific means by which researchers and statisticians seek to avoid these data manipulations in sampling. An overarching approach is to ensure that the survey method is designed in as clear and unbiased as possible. In these regards, Edwards (2010, pg. 26-27) identifies a number of key features to avoid, â€Å"failure of the questionnaire...failure to recognize differences between various kinds and degrees of canvass and to fit the questions to the type of canvass...failure to define the universe with enough precision and to provide a satisfactory frame.† Adhering to these methods greatly aids the research av oid data manipulation. In addition to these areas that must be considered when constructing sampling data, there are features that must be considered to avoid sampling bias. As a means of avoiding data manipulation in sampling its generally recommended that researchers implement random sampling as an overarching model. A random sample consists of a random sampling of survey participants and can be conducted through a number of means. Among these involve a simple random sample, stratified sampling, and cluster sampling, with their distinguishing features based on the means by which they select the sample group (Thompson 2002). When examining sample data from the random sample its important to consider the possible statistical error that can be included, as such errors can be utilized in data manipulation when in actuality they are necessary elements of the research. In these regards, human failure must be avoided as

Judiasm Essay Example | Topics and Well Written Essays - 750 words - 1

Judiasm - Essay Example One needs to include the thinking of a modern national identity that has a link with a specific land and culture and lastly, the description of Judaism must include the diverse sense of ethnicity allowing for secular Jews. Judaism cannot be generalized to refer solely or primarily to a religious faith as not all Jews believe in one God. There are some Jews who do not take part in the synagogue or home rituals. It is not, therefore, enough to say Judaism is merely faith among the many world religions. It should be clear to people that Jew and Judaism are relatively modern terms that need not be applied to the scriptural description of Judeans, Hebrews, and Israelites. This is to mean, the Judaism and Jews of this modern time have nothing to do with the scriptural description of the Hebrews, or the Christian scripture or the later church tradition. Not all Israelis are Jews, at the same time, it is important to understand that not all the Jews have a connection with the State of Israel. The scriptural Israelites should also not be confused with the todays Israelis. At the same time, the Jews should not be confused with the Hebrews or the scriptural Hebrews in either the Old or New Testaments. In each instance above, the term Jew has a different meaning. Judaism celebrates having both rich weekly and annual calendar. In their calendar, the Sabbath becomes their holiest day. The Sabbath here begins from Friday night to Saturday night. Both the creation of the universe and the Egypt exodus are related to the Sabbath, hence because its holiness. The period 1000-1650 C.E is referred to as the medieval period by the Jews where their relation with the major cultures and religions of both Islam and Christianity, took place. During this period, there was a tormented relationship between Judaism and Christianity. The period is also marked with the expelling of the Jews from the major

The role of temporary works in civil Engineering Construction Assignment

The role of temporary works in civil Engineering Construction - Assignment Example For example when setting up a scaffold it is advisable that your scaffold is supported by the ground but if that is not possible one can make it to hang above the ground or water using the hanging scaffold (Webster 1997). A good scaffold should also be able to have a safety mechanism in order to avoid injuries in case the scaffold fails thus in constructing a bridge one can chose to attach himself to the bridge to be safe incase the scaffold is failing. Formwork In his contribution Blackledge (1977) refers to formwork as the process that involves the addition of base material and also the addition of concrete that is in retaining wall so that they can be used as slabs during the construction of a bridge. Formwork is very essential since it helps to make the concrete last for long due to the fact that it makes it strong (Blackledge 1977). The strength property of formwork guarantees the much needed support that is needed in construction of the bridge. Formworks is used by making that needed shape using steel or aluminum so that the concrete is then poured into it so that a desired shape is produced. This is then allowed to harden. When it’s all dry the fabrications are removed and the formwork remains in place in that desired shape. Formwork is used to guarantees the strong support for the bridge during construction which always has to remain strong to avoid collapse (Blackledge 1977). Falsework In his book Webster (1997) talks of falsework as a term that is used to refer to the activity of supporting arches and spans in the process of constructing a bridge by using temporary support structures. This is a very essential practice in construction of bridges since it helps support the bridges from below in order to ensure that the bridges do not collapse as the construction is still continuing and can also be used to create a strong work base for the workers during the process of constructing a bridge. This always has to remain intact to the construction unt il that time when the bridge can self support itself without collapsing which in the long run helps to keep the bridge in position (Webster 1997). Temporary Support of Excavation During construction of a bridge it might involve excavating various sections of the work site so as to achieve a certain level of ease during the construction of bridge (Hummell 2011). For example during construction when the building is to start like two stories below the ground then excavation will have to be done in order to achieve this. Also good to notice is that sometime exaction is done for example when gravel is need for construction so that it is dug from a place. After excavation it’s a good practice to always support the excavations in order to avoid collapse of the walls during construction according to Hummell (2011). There are two types of excavation that can be used in supporting an excavation walls; this can either be flexible support or rigid excavation support. When one uses Flexib le support then it would take sheet pilling, soldier pile and lagging walls. On the other hand rigid support entails slurry walls, secant piles or even tangent pile (Hummell 2011). Construction Dewatering In his deep insight on dewatering Hummell (2011) talks of this process as a way that is used to achieve a certain degree of ease at the work site by ensuring that the water that may cause difficulty during the

What I have learned from men Research Paper Example | Topics and Well Written Essays - 1000 words

What I have learned from men - Research Paper Example In my opinion, most of her arguments are valid however she overlooks certain facts by making false generalizations. The article deserves a lot of credits since it offers a clear explanation to the topic. The writer has used both a sarcastic and a serious tone to drive her message home. It is a dependable source of information for the topic since it gives credit where it is due. The author does not favor any gender and she criticizes both men and women characters. Although her main aim is to explain the fact that women should change their characters, she does not appreciate a woman’s natural character. As a woman writer, it is expected that she would defend women but instead she criticizes them. This criticism allows the reader to explore her views more closely and to clarify her views. Ehrenreich does not agree with the fact that women are the way they are because they were created that way. She considers that as a fallacy and takes firms stands to her arguments. I accord with most of her arguments, but she seems to get the fact of diversity wrong. Men and women are naturally different and very diverse in their character. However, she does not seem to give value to diversity, and her believe is that women are the way they are because they haven’t tried changing. Ehrenreich is very bitter about the expectation of the society that women should always act in a soft manner. She reiterates that it is not the job of a woman to be polite. The writer seems to have little discernment for politeness, and all her emphasis is on women and men equality. She considers that if women get to be harsh like men, gender equality will be achieved and gender-based exploitation will be history. She strongly criticizes the normality of women being soft in conversations. She does not see the reason why women should act ‘good’ by being soft and yet they it has little or no benefit

It is a financial approach which refers to get hold on active selling and purchase dealings in short term profitability scenarios while having an intension to make investment in secure long term profitability with a minimum usage of resources (John L. Maginn, 2010). The passive investment approach is hugely relied and believes on pre determined strategy where there is no span for any potential anticipation rather strongly belief by fund manager or any financier to invest in long-standing period will be highly cost-effective. The whole stance is to evaluate the investment to its minimum level and to keep away negative impacts in the case of m alfunction in order to appropriately forecasting. Passive management is extremely viable in stock market in which index tracker is used to assess the index for equity market (John L. Maginn, 2010). Now days, it is gaining popularity and also being exploited progressively in other types of investment portfolios include bonds, supplies and hedge funds.

To live outside Essay Example for Free

To live outside Essay As I stand still in the traffic filled New York City Street attempting to crawl as if I were a turtle trying to cross the road, I begin to contemplate the true beauty of living in the city. It is now the month where everything should be glooming, pleasing, and living, however it is not. In the Waste Land by Thomas Sterns Eliot, he states, April is the cruellest month. This is a metaphor which in my situation reflects the truth. There are many reasons as to why people prefer to live outside of the city but work in the heart of it. I look forward and try to imagine what T.S. Eliot would think if he saw these city streets. In his book, the Waste Land, it is forced into our imagination that the world is dead; the earth is a waste land. He calls the city an Unreal City, making the reader think of the city that is referred to as a place worse than any nightmares can ever imagine. When imagining a city that I do not want to live in, first thing that comes to mind is a city thats always dirty and cold. If one was to analyze New York City, it can easily be found that most of the time it is cold; cold enough to need someone there with you if you do not have a home. Just as in the book you would read in the first story that you can only be kept warm in the winter with someone next to you. It is written, Winter kept us warm. It is also dirty to the extent that the street cleaning trucks that are made to clean the streets cannot handle the amount of filth the ground holds. The Waste Land takes on the degraded mess that Eliot considered modern culture to constitute, particularly after the First World War had ravaged Europe. April is the month that everything should be regenerating. Regeneration, though, is painful, for it brings back reminders of a more fertile and happier past. In the modern world, winter, the time of forgetfulness and numbness, is indeed preferable. Maries childhood recollections are also painful: the simple world of cousins, sledding, and coffee in the park has been replaced by a complex set of emotional and political consequences resulting from the war. The topic of memory, particularly when it involves remembering the dead, is of critical importance in The Waste Land. Memory creates a confrontation of the past with the present, a combination that points out just how badly things have  decayed. The final episode of the Waste Land allows Eliot to finally establish the true wasteland of the poem, the modern city. Eliots London references Baudelaires Paris (Unreal City), Dickenss London (the brown fog of a winter dawn) and Dantes hell (the flowing crowd of the dead). The city is desolate and depopulated, inhabited only by ghosts from the past. Stetson, the spirit of the speaker recognizes, is a fallen war comrade. The speaker pesters him with a series of ghoulish questions about a corpse buried in his garden: again, with the garden, we return to the theme of regeneration and fertility. This encounter can be read as a quest for a meaning behind the tremendous slaughter of the First World War; however, it can also be read as an exercise in ultimate futility: as we see in Stetsons failure to respond to the speakers inquiries, the dead offer few answers. The great respective weights of history, tradition, and the poets dead predecessors combine to create an oppressive burden. In conclusion, there are many reasons as to why people prefer to live outside of the city, yet work in the center of it. In the first episode of the Waste Land by T.S. Eliot, the city that is described is one that is regenerating because as it is beaten into your mind, the city is dead. Eliot speaks about the land and how dust filled it is and how nothing is alive. He then explains that everything is reviving, but that means that at the current time, after the First World War, everything is dead and life totally different then it was earlier. Even though he talks about the city and how unreal it is, he explains that Marie has recollections of sledding and family life. Usually family life and things like sledding are pastimes in a more countryside based area. Therefore, it is as if he is saying that city life is no longer good, while Marie remembers the good times she had sledding in the countryside. In the last episode, we, the readers, can see even more about how Eliot perceives the city. He refers to other stories to explain this city. He uses Dantes Hell as well as Dickenss London to explain the dead streets and the ghost roaming them. He uses a fallen soldier as the main character and shows  that the streets are full of ghost and no one living. If you would look at the city in the modern times, you can imagine people having nothing on their mind but work. They wander the city streets going nowhere but to their place of work, being worried of getting fired and not being human to the extent that they are forced to do something. It is if they are roaming the streets just like the ghosts, however, these people dont think that they are dead. Just like the saying goes, I come alive on the weekends. Then you can imagine that the soldiers that did return breathing would want to live in a place where it is peaceful and quiet. The countryside is where they would most likely find this. Therefore, it can be seen that the ghost or the workers work in the city, while the living stay home in the countryside.

Compare CAD and Manual Drawing

Compare CAD and Manual Drawing P1) Identify and describe a range of equipment, furniture and media necessary to produce manual and CAD drawings for the projects. Manual There are four types of materials traditionally used for drafting, which come in arrange of sizes including; A1, A2 and A3. Types of Paper used for drafting; Bond This is similar to the paper used everyday in office printers. Its the least expensive paper and is usually supplied in roll form for drafting plotters. Bond paper is most commonly used in weights from 18 lb all the way up to 24 lb, but much heavier weights are available and used for mainly posters and presentation work. Mylar This is a drafting film made from plastic material. It has the advantage of being erasable which, if you are working in ink, is a great advantage. Its also semi transparent, making it possible to overlay mylar drawings on a light table to check if line work matches up. The film is however more resistant to tears but is more durable than paper. It is still used with drafting plotters and is available in roll form and in cut sheets. Mylar has a matte side and a shiny side which you draw on. The surface of mylar is quite slippery, and therefore pen companies in the past have released special pens and inks which are developed specifically for drawing on it. Modern plotters have found problems printing on mylar as the material does not absorb ink quickly and therefore is prone to smudging as well as unclear lines. Where as bond paper is far more absorbent and does not smudge so easily. Mylar is also quite expensive. Vellum This is a linen based paper that has traditionally been used for historical building plans along with many drafting offices. The high linen content makes it durable and allows pencil work to be easily erased and revised multiple times. Its not as strong as mylar material but is not as expensive. Vellum also has a smooth surface which does not absorb ink as fast as bond paper. That may cause problems with the ink smudging and therefore is not fit for purpose if used for printing. With this said vellum paper is no longer used today to draft plans. Photo With the advances in drafting printers, photo media became available in roll form for printing super size renderings and images. Its a costly media and is usually reserved for the best of presentation graphics. But it allows the engineering office to do more by taking on work that was previously done by printing shops and the graphic designer. Although these are the four main materials used for drafting tracing has also been used in the past in the drawing industry, but is still heavily used for smaller scale work, such as; school/college/university projects, art projects and much more. Tracing Paper this paper is thin and translucent which enables the drawer to copy the image/design several times easily. The faint lines of the image/design are then re-drawn in pencil and are later filled in using a specific drawing pen. The paper comes in a range of grades for drafting work. They start at around 80g/m2 and go up to around 110g/m2 when there are master copies needed. In the past tracing paper when copied using a ammonia copier it was prone to fading in the light and therefore was not clearly visible. However this problem does not occur anymore due to the introduction of photocopying machines which have no side effects as yet. Drawing boards The drafting table is still in use despite all the advances in computer aided drafting. There are still many individuals who still use the traditional drawing table. Architects, graphic artists and many structural steel drafters use the drawing table to make and modify there drawings on paper along with pencil or ink. Drawing boards are large tables which are angled with a lip and a rule which slides up and down the board. The instruments allow you to create parallel, perpendicular and diagonal lines. Drawing boards are becoming less popular due to the introduction of Computer Aided Design. Pencils These are the main working tool of a draftsperson and are available in arrange of harnesses. The darkest pencil used for technical drawings is a B which is used for shading and adding texture to a drawing. The HB pencil follows which is the most commonly used on a day to day basis but is only used for rough sketches for drafting. The F is used for printing and general line work. Following on from the F is the H pencil which is used for dimension lines and hatching by draftspersons. Finally is the 2H which is used for construction lines. For the finest drawings, all pencils used must be permanently sharp and have standard, smooth point. A soft rubber is used for rubbing out pencil lines. Scale rules Drawing are produced to a particular scale which will fully fit onto a drawing sheet. The main tool which helps you draw scale drawings more easily is a scale rule, the most common scales; 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:250, 1:500, 1:1000, 1:1250 and 1:2500. g/m2: refers to the paper quality and weight Tee Square It can be used as a guide for architectural and mechanical drawings. It consists of two arms joined at 90 degree angles. The smaller arm moves along the edge of the drawing board and the larger arm is used to draw straight parallel lines. It can also be used to support set squares which can draw lines at different angles. Adjustable set squares These are mainly used to draw vertical lines at 90 degree angles to the parallel motion arm. A set square can also produce a line at any angle on the paper by adjusting the scale of the protractor. Propelling Pencils A propelling pencil is very thin and can be easily replicable. Unlike a normal standard pencil a propelling pencil always stays sharp due to the thinness of the lead. The most common leads are 0.5 and 0.7. You can also purchase leads in thicknesses of 0.3, 0.9 and 2mm. Compass These are used to create circles and arcs when drawing. Precision sets include a thumbwheel compass. A standard compass set includes an extension arm, a pen clamp and replaceable leads. The purpose of an extension arm is to draw larger arcs and circles with the same amount of precision. Protractor They are generally made from transparent plastic. Protractors can come either in semi-circle or full 360 degree form. There are bevel protractors which are circular protractors with a pivoted arm used for accurately measuring and creating angles to draw from. Rubbers Rubbers come in a large variety of shapes and form. The trapezium shaped is preferred as its points can rub out pencil lines more accurately. Plastic and putty rubbers can be moulded into points to carry out similar work. CAD For CAD to be successfully installed and used the computer which will run this software must have CPU with 3 GHz or more. This number of GHz will allow the CAD software to run at the correct speed rather than it crashing/freezing. Microsoft Windows Vista or Microsoft XP are both operating systems which allow CAD to be used successfully. The computer will also need 2GB of RAM on its operating disk and 2GB of free space minimum on its hard drive. The computer screen must have revolutions of at least 12801024 pixels which will include a display adapter which is able to produce 32-bite colour 128MB or more if possible. There are three main hardware configurations for the use of a CAD system. Depending on the size of the company and office will decide which hardware will be in use. The first software configuration is a standalone single user which simply means that the information and software is held by a private domain. Therefore CAD drawings can only be sent by email or sent by post. The next main hardware configuration is a small office based intranet where CAD drawings and document information is held in a project folder which is within the computers server. The work is organised by a plot management function which segregates the drawings in order of importance. Therefore the company can easily track and record the drawings within the software easily. Finally the third main hardware configuration is a large multi located extranet set up for a wide area network which contains various members of a project team which are more often than not in different parts of the country or countries. As there may be members of the project team in another country this extranet allows the members to easily access the drawings or information which has been uploaded from the drawing office onto the internet through subscription. Mouses, keyboards, digitisers/pads and light pens are used everyday by CAD workers. Mouses A standard mouse has two buttons which are positioned where your fingers lie on the mouse. 2D motion ball mouses are also used and easily direct the mouse much like a standard mouse. More advanced mouses include scroll buttons or additional buttons which are found on the side of the mouse which allow the user to carry out a task quicker. Laser mouses are far more accurate than a standard mouse as the movements are a lot more refined. There are more advanced mouses like the trackball mouse which are far more accurate due to the trackball which is located at the top of the mouse. These mouses are used by designers, gamers and web designers. The actual trackball contains optical and mechanical sensors which are able to track movement and therefore gain on accuracy. Keyboards The most common is the QWERTY keyboard which is used for everyday life and has all requirements covered. However if you are sat at your desk in the office all day you may face some health and safety issues due to the basic design of the QWERTY keyboard. Therefore there are keyboards specifically designed for this issue which are called Ergonomic keyboards which are designed to relieve stress. Using a keyboard can result to carpal tunnel syndrome and repetitive stress injury therefore the ergonomic keyboard was designed for this purpose and is recommended by doctors. Finally there is the DVORAK keyboard which is an ergonomic alternative to the QWERTY keyboard. QWERTY keyboards were designed to comply with typewriters and therefore they are ineffective for touch typing. For that reason the DVORAK keyboard was invented for touch typing which also adds to the comfort of the typer. Digitisers/pads and light pens These are electronic drawing pads which allow people to easily draw and scribe free hand. This enables easier usage of the computer. P4 AutoCAD AutoCAD is usually used on Microsoft desktop software and is available in around 20 languages. It is a form of CAD software which is used to produce 2/3 dimensional designs. AutoCAD can be used for a range of tasks including designing landscapes, buildings and automotive machinery. The earlier versions of AutoCAD used basic functions which included lines, circles, arcs, plotlines and text. The latest version of AutoCAD is more advanced than the earlier additions and is able to form solid modelling such as creating prisms, boxes and spheres. There are also far more detailed and accurate models which use 3D tools. There are many support programs which use AutoCAD such as Auto LISP, VBA, Object ARX and Visual LISP. Object ARX is a base model which helped create AutoCAD Architecture, AutoCAD Civil 3D and AutoCAD Electrical. AutoCAD LT This is a smaller, cheaper version of AutoCAD which can easily be purchased from computer stores unlike the full version of AutoCAD, purely due to the cost of the who AutoCAD programs. AutoCAD LT costs around $900 where as the full version of AutoCAD costs around $4000 which is far more specialist. AutoCAD LT costs around a quarter of the price of the AutoCAD full version as it has to compete with other similar softwares where as the full version of AutoCAD is unique and is the only software of its type used by company in this sector of work. However due to the cheapness of AutoCAD LT software there are some features which are excluded from this software which are included on the full version of AutoCAD. One of the features excluded from the LT version is the 3D function, others include the exclusion of LISP programs and the inability to interact with 3rd party programs. AutoCAD student version This version has a noticeable price difference for student, teachers and lecturers, and can be licensed for 14 months. There are few features which are included on AutoCAD but of which are excluded from the AutoCAD student version. However when a DWG file is created or changed by the student the file is given an educational flag and when this type of file is printed on AutoCAD software it has a plot stamp or banner on all four sides and therefore makes it invalid for commercial use. If a student imports a DWG commercial file they will infect the file so that it can then be used commercially. Also a registered student can has access to free AutoDesk applications from the AutoDesk community. Hence the student therefore has access to the Civil 3D version and the Architectural version of AutoCAD softwares. Other AutoCAD softwares There are many vertical programs which have been designed such as AutoCAD Architecture or AutoCAD Civil 3D. These vertical programs allow the designer to illustrate 3D objects with more intelligent data rather than using sample lines, circles and other solid objects. The program can also be programmed to symbolize products used to construct the design. Therefore the data can be used to estimate the overall cost for the construction of the building, the cost of the materials and other values needed for the building as a whole. Managing CAD Designers need to be assured that the CAD software will save, store and manage their work efficiently so that it can easily be found if changes are required. To achieve this, major companys have different files for their software. Graphisofts ArchiCAD is an example of this. This software depending on whether the data is two or three dimensional, Graphisofts ArchiCAD uses a filing system of which the designers work is stored in a drawing database. DWG files can be easily imported onto this system and this allows a larger range of information to be stored. Thanks to the DWG software, the latest version of CAD has been strengthened and developed by using the DWG software as the primary file format. Due to the filing system employed by the DWG system it is popular with most designers. Due to frequent updates CAD is now a well-built piece of software and has helped improve modern day computers due to the requirements needed to run the CAD software successfully. The modern day computer now has a greater ram, better resolutions, far more memory, superior CPU and more enhanced hard drives which means that the computer can easily support the softwares which are ran through them. CAD can project an image in several ways, of which include; Orthographically, Isometrically, Axonometrically and can use perspective views but sometimes an exploded view is used. An exploded view can take apart an image to show the parts and layers which enables you to examine all parts of the original image. This view is used by Architects and Engineers to enable them to perfect their projects. A designer can use pre-set symbols to represent objects such as doors for a cross section of a building. CAD also allows you to use standard house designs, which can save time for architects and therefore allows them to be ahead of the project and deadlines. The CAD software allows you to easily save work into electronic drawings and also enables you to transfer drawings by email. CAD enables you to create very realistic designs and images depending on the specific CAD software which you are using. The software allows you to create 3D virtual environments which include pictures of real life buildings and people. Other softwares enable you to create naturalistic textures including sunlight, shadows, plants which move in the wind and people walking or moving. To meet the clients needs certain CAD programs allow you to create walkthroughs. This allows the client to visually see their building in a realistic view rather than two or three dimensional form drawing. Advantages and Disadvantages of using CAD and Manual drawings Manual Drawings Advantages; Cheaper to buy the equipment needed to construct the drawings such as set squares or scale rules. If the equipment is broken or not working correctly the user can simply buy a new one without having to go to allot of trouble. The equipment never needs updating as it is already adequate to carry out the job correctly. If you are on site it is far easier to use a manual drawing as you are able to get a better perspective and scale. Easy to modify a manual drawing. You do not need as much technical ability. You always have a hard copy. Disadvantages; Takes a long time to post or fax the drawing to the client. Need a large, light area to set out and work on the drawing. The equipment can be effected by human error maybe a shaky hand. It takes a long time to construct or reproduce a drawing when manually drawing. It is difficult to get the pressure applied to the pencil to determine the type of line you are looking to achieve whether it is a tracer line or primary line. A manual drawing can get easily damaged. A manual drawing is far harder to store as each drawing takes up space and you need put a storage system in place so that each individual drawing can easily be found. CAD Advantages; The drawing can be accurate as the tolls on the software are electronic so they wont be affected by human error such as the incorrect thickness of line. The user can save their work to any electronic storage device such as the hard drive of the computer or a CD or even a memory stick. The computer memorises the drawing in every dimension possible so that the user doesnt have to waste time trying to remember what the drawing looked like and which is which drawing. It is very easy for the user to rectify any mistakes they have made or to move a part of the drawing. Rotate a 3D drawing or to erase any irrelevant parts. The drawing can be transferred by email, saving on postage time and cost. CAD is far quicker to use. The storage and organisation of drawing using CAD software means drawings can easily be stored, dont take up any office space and are well organised and maintained. Disadvantages; Some shapes are still very difficult to draw using CAD software. It is very expensive to purchase CAD software no matter what version you choose. The computer and the necessary equipment needed have to be maintained and regularly updated which adds to costs. If the software was to crash or something went wrong it will need to be fixed by a professional in this field of work which costs time and money. CAD is very difficult to use and is regularly updated, therefore it is very hard to use and understand. As a result you will regularly need to be trained on how to use the software which adds to costs and time. If the software was to break all of the drawings and information ever saved on the computer software may be lost. CAD is not always suitable for site work. There are always doubts concerning glitches or viruses to the computer system. How the quality of graphical information significantly affects the quality of the completed civil engineering/construction project. In the construction industry finished work it contains a number of things such as the written specification; whether the designers requirements were met or not; whether the contractor has estimated the cost accurately or not; the products are ordered within time; whether the design and construction team have kept misunderstandings to a minimum. Consequently the graphical information for the civil engineering/construction project must always be correct and accurate. The graphical information should include every single material or item that is needed for the civil engineering/construction project with all its specifications. The designer must ensure they have created an accurate drawing along with a detailed schedule plan. This will ensure the contractor has the all of the correct products ordered before the work is supposed to commence. However if the architect or designer knows they have not achieved an accurate drawing they may include a schedule which they have used already on a similar project so that they can spend the remaining time modifying their drawing so that it meets their own and the clients standards. Though this may save time for the architect to create a perfectly accurate drawing the schedule is inaccurate and therefore lowers the standard of the project and also may add to costs as they may have the wrong equipment as the schedule is not specific to the project. If the schedule initiates up to the construction stage this may cause the project to run past the deadline dates and therefore add cost to the overall project. If the designer creates an accurate drawing for the project which is specific and contains the specific schedule it means that the overall finished construction of the project should also be of a high quality because it allows the contractors to plan ahead before the construction work starts. But if a schedule of high quality is used on the project which has originally used on a similar project the quality of the overall construction will suffer as a result. So no matter how detailed a schedule or information is on the drawing will only create a high quality project if it is specific and accurate to the job.

Helping an Ignorant Society :: Argumentative Persuasive Sociology Essays

Helping an Ignorant Society So many people go through life thinking that someone who is different from them is bad, unintelligent, out of the norm and sometimes even worse. Discrimination occurs all the time because we are so ignorant about our differences. In elementary school children often notice that someone has a different skin color, speaks English funny, or sometimes that people are fat or ugly. The school children make fun of these people because they are different from what they are used to. As you grow older you do not let go of these stereotypes. People put labels on other people and do not realize that they are even discriminating. In our society it is normal to make jokes about different religions and cultures, and no one tries to stop the prejudice. We often hear the phrase its a free country, I will say what I want, if our country is free, then why cant people who are different that your average American be free too? Why do they have to deal with discrimination? Our colleges need to offer a progr am that emphasizes the fact that everyone is different, and teach about our differences. Knowing that we are different will show people that our differences are not bad, but rather, that they are good. As children we love and admire our families. Our parents teach us our morals and values, and we learn what is right from wrong. We are punished when we are bad, and rewarded when we are good. These things make us the people that we are. We all keep our values close to our hearts, as bell hooks points out in her essay Keeping Close to Home: Class and Education, with these words, While I often needed more money, I never needed a new set of beliefs and values(96). No matter how hard our life is at any point in time, our values will stay with us always. That is why education starts from the moment you are born. First you learn through your senses, you see colors and learn to tell the differences from your parents and siblings. You know who you can trust and who is mean. The first five years are the most influential of a childs entire life. Since education starts at this early age, I feel that parents are responsible to teach their children social skills. The parents need to explain why we are all different and that our differences are good, otherwise we would all be exactly the same, and that would be boring.

Metabolic Control Analysis(MCA) Essay -- Science Biochemistry

Introduction: In 1970s, a new method called (Metabolic Control Analysis) for analysing the distribution control of the flows and medium concentrations in the metabolic path between different enzymes that form the corridor, was developed by Henrik Kacser and other scientists. Since then, attention was paid to more research in this method and its applications, and developing analytical and educational tools (Wildermuth, 2000). In the flowing literature review, some examples of the significance of Metabolic Control Analysis, pros and cons will be discussed. Literature review: At first glance, engineering a metabolic system with aim of raising metabolite's yield or flux during a metabolic pathway system, could be done through the method of identifying and controlling, which called rate-limiting-steps. Rate-limiting steps is a certain steps in the paths that exercising the most control over the whole system. Though the good features of this method, the majority of experiments that were tried using that method to increase the pathway fluxes ended up with failure (Walker and Raply, 2009). In fact, the control of the system as a whole is distributed across the system’s components much more than esteemed. This area of distributed is a part of sensitivity analysis, which offered lots of applications for many engineering specializations and for economics as well. According to (Walker and Raply, 2009 ; Gunawardena, 2002), metabolic control analysis (MCA), was developed in 1973 in Edinburgh, by Henrik Kacser and Jim Burns, and, autonomously in Berlin in1974, by Reinhart Heinrich and Tom Rapaport through application of the general concept of sensitivity analysis, to provide a precise quantitative basis to determ... ... control and regulation. However, it is a good point to start for improving access to a deeper understanding better than what can be given by qualitative of conventional biochemistry. Works Cited Fell, D. (1997).

Human cloning Essay

If there was one technology that the world never accepted, then it will be the cloning of humans. Just 30 hours after the news of a cloned lamb hit the streets, movements against human cloning already started forming (Pence 1998, p. 1). 90 days after the study, a law against human cloning was already being pushed. People claimed that there is no good reason to clone humans, and yet, how can this be known when there wasn’t enough time to discuss it? When the scientific community did not even have time to prove its advantages? Most of the arguments against cloning are philosophical in nature. It is not about â€Å"scientific facts but about ethics, human nature and public policy† (Pence 1998, p. 3). If we look at human cloning in an objective point of view we will realize that there are certain merits to this technology. Certainly, there are disadvantages too, but whether the disadvantages outweigh the advantages is still a question unresolved today. Advantages of Human Cloning Human cloning becomes a good prospect when we talk about the issue of infertility and genetic illnesses. In an article published by ScienceRay (Whatani 2008), it was mentioned that only half of the population of females are capable of gestation. Estimates show that current infertility treatments are only 10% effective (Benefits of Cloning n. d) hence, there are many couples who end up getting frustrated because of their inability to have children. With human cloning, there is no need for the egg to be fertilized, and there is no need to find a mate, and only one parent is needed to create a child (Teacher’s Domain 2010). Researches show that an average person carries 8 defective genes (Benefits of Cloning n. d). In some cases, these genes are recessive and no symptoms will appear, but there are also instances when the genes are inherited by the children and they become dominant traits. Down’s syndrome and Tay Sach’s disease are just two genetic illnesses which can be inherited if reproduction is left to natural means. Though human cloning, parents can choose which genes their children will inherit, thereby allowing them to get rid of the defective genes. Another advantage of cloning is that it is now possible to create organs which can be used for transplants (The Advantages of Cloning n. d). People with liver and kidney trouble no longer need to wait for a donor to get a transplant. People suffering from leukemia can get cloned marrow. Scientists will be able to produce effective therapy for cystic fibrosis if only they are allowed to test the technology for human cloning. Lastly, cloning will allow medical professionals to understand how cells differentiate and become cancer cells, thereby allowing the creation of a cure for the disease. Disadvantages of Sexual Reproduction In several researches conducted (Science Daily 2006; Treisman 1976; Williams and Mitton 1973) it was discovered that sexual reproduction allows populations to adapt to their environment better because they are able to resist harmful mutations. Yet, sexually transmitted diseases are already so widespread that sex has become risky. Also, sexual reproduction has its costs wherein the female carry most of the burden, a situation called as the two-fold costs of sex (Science Daily 2006). In his study, Ricardo Azevedo says that in order to overcome the two-fold cost of sex, two things must be true ‘†The production rate of harmful mutations must be relatively high, such that each individual acquires on average one or more harmful germline mutations not inherited from its parents. The second is that these harmful mutations must interact in a special way, called negative epistasis, such that adding more and more harmful mutations makes you progressively worse off (Science Daily 2006)†. This means that in order for genetic illnesses and harmful mutations to become extinct, these two conditions must take place. Needless to say, there are no studies which show how prevalent negative epistasis is in nature, hence the extinction of genetic illnesses and mutations are purely by chance. With the world becoming even more chaotic because of the discovery of new incurable diseases and the rapidly degrading environment, there is a big possibility that the survival of humankind may need to rely with artificial means. With human cloning, it is now possible to create a healthier, if not a better race of individuals who are more resistant to mutations and have lesser diseases to endure (Phil for Humanity n. d).

Morality and Sacrifice Essay

â€Å"Sacrifice† is the surrender of a greater value for the sake of a lesser one or of a non value. Thus, altruism gauges a man’s virtue by the degree to which he surrenders, renounces or betrays his values (since help to a stranger or an enemy is regarded as more virtuous, less â€Å"selfish,† than help to those one loves). The rational principle of conduct is the exact opposite: always act in accordance with the hierarchy of your values, and never sacrifice a greater value to a lesser one. â€Å"Sacrifice† does not mean the rejection of the worthless, but of the precious. â€Å"Sacrifice† does not mean the rejection of the evil for the sake of the good, but of the good for the sake of the evil. â€Å"Sacrifice† is the surrender of that which you value in favor of that which you don’t. If you exchange a penny for a dollar, it is not a sacrifice; if you exchange a dollar for a penny, it is. If you achieve the career you wanted, after years of struggle, it is not a sacrifice; if you then renounce it for the sake of a rival, it is. A sacrifice is the surrender of a value. Full sacrifice is full surrender of all values. If you wish to achieve full virtue, you must seek no gratitude in return for your sacrifice, no praise, no love, no admiration, no self-esteem, not even the pride of being virtuous; the faintest trace of any gain dilutes your virtue. If you pursue a course of action that does not taint your life by any joy, that brings you no value in matter, no value in spirit, no gain, no profit, no reward—if you achieve this state of total zero, you have achieved the ideal of moral perfection. If you wish to save the last of your dignity, do not call your best actions a â€Å"sacrifice†: that term brands you as immoral. If a mother buys food for her hungry child rather than a hat for herself, it is not a sacrifice: she values the child higher than the hat; but it is a sacrifice to the kind of mother whose higher value is the hat, who would prefer her child to starve and feeds him only from a sense of duty. If a man dies fighting for his own freedom, it is not a sacrifice: he is not willing to live as a slave; but it is a sacrifice to the kind of man who’s willing. If a man refuses to sell his convictions, it is not a sacrifice, unless he is the sort of man who has no convictions. Sacrifice could be proper only for those who have nothing to sacrifice—no values, no standards, no judgment—those whose desires are irrational whims, blindly conceived and lightly surrendered. For a man of moral stature, whose desires are born of rational values, sacrifice is the surrender of the right to the wrong, of the good to the evil. The creed of sacrifice is a morality for the immoral—a morality that declares its own bankruptcy by confessing that it can’t impart to men any personal stake in virtues or values, and that their souls are sewers of depravity, which they must be taught to sacrifice. By its own confession, it is impotent to teach men to be good and can only subject them to constant punishment.
