Nassar 1 Eman E.Nassar1 ISSN 1333-11243 eISSN 1849-1391 NUMERICAL PREDICTIONS OF THE MECHANICAL PROPERTIES OF A356-SiC COMPOSITES FABRICATED BY POWDER METALLURGY Summary Pure aluminum nanocomposite reinforced with silicon carbide was produced by powder metallurgy route. Modeling investigations and mechanical experiments were carried out on the mechanical Behviour. of this nanocomposites .Measurements of density, tensile properties and hardness showed that the tensile strength and the porosity of composites increased with the increasing in the amount of the nanoparticles; however, aluminum ductility was decreased. On the other hand, the elongation percentage keeps constant with the increasing in the percentage of the nanoparticles. Wear resistance increased in the composite samples comparing to alloy. In the current research, a technique based on Artificial Neural Network (ANN) and Finite Element Method (FEM) was implemented to predict mechanical properties. It was observed that prediction results in this study are consistent with the real measurements for composites. keywords: nano SiC, finite element method, artificial neural network.

W L Gore Case Study - 2356 Words

ASSIGNMENT 2 - CASE STUDY High Performance at W L GORE Service/Product: Gore-Tex manufacturer Famous for: Inventing world-renowned high-performance fabrics for leisure, industrial, electronic and medical purposes The business strategy: Delivering continuous innovation by turning management principles on their head High performance learning points: †¢ Unique form of work organisation designed to support employee collaboration and creativity; †¢ Leaders replace managers to deliver high levels of innovation; †¢ Use of informal communication to achieve high levels of trust; †¢ Use of ’sponsors to facilitate continuous development and training and achieve a close link between personal development and organisational needs; †¢ Remuneration†¦show more content†¦All this requires that substantial skills are built up among staff at all levels. Together these create a powerful sense of identification with the company and attachment to its values. From this flows a high level of performance in the form of constant innovation. One of the keys to this form of work organisation is the fact that the operating units are kept small, ideally between 150 and 170 associates. All are members of multidisciplinary teams, for example, an HR team, teams of engineers, manufacturing teams, but these are constantly changing in terms of their composition. Some are global in their membership, such as the IT team and the leadership team in fabrics, the latter being made up of a German, American and UK person. Most teams are local in that if a person comes up with the idea for a new product, say in connection with motorcycle clothing, then he or she takes on the leadership of that team, followed by others who have an interest or specialist knowledge in the area. The result is that teams are constantly changing, creating an organisation that takes on an amoeba-like quality. Members of the team determine their objectives, their mode of operating and their composition. If a person wishes to join a new team, because they are interested in the idea and feel they would like to contribute to it, then theyShow MoreRelatedCase Study : Gore Associates Case Study1553 Words   |  7 Pages W.L.

Meat Science and Animal Nutrition Free Essays

I want to get a masters degree in animal industries in order to prepare for my future career. There were two options I’ve been considering, consisting of meat science and animal nutrition. Both options, I believe, would help me land a career in concerned government agencies. We will write a custom essay sample on Meat Science and Animal Nutrition or any similar topic only for you Order Now It would also open the doors to further studies, such as veterinary medicine, should I decide to pursue it. From the two options I am leaning more in favor of taking up meat science, as it is more concerned with food safety and nutrition. I am interested in understanding factors that affect the nutritional value and consumer acceptability of meat, which eventually lead to consumer health and satisfaction. I believe that meat science is not a popular choice for people, but it is equally important to ensure the health of the public. I could gain knowledge that should be shared and disseminated to people. Thus, this course could equip me with the knowledge I need to serve in government agencies such as the United States Department of Agriculture Food Safety and Inspection Service, and be a food safety specialist who answers questions of consumers regarding food preparation, storage, and handling. The importance of the role I could play towards protecting the health and safety of the public is a good reason for me to pursue this course.

President Obamas famously i... free essay sample

President Obamas famously inspirational second inaugural speech delivered on the day of inauguration was given as a thanking speech combined by a declaration of needs to urge Americans to reclaim from conservatives the spirit of the founding fathers for equality among all. Americas first African American President who believed in democracy and believed in peace, justice, and most importantly equality. The speech shared much emotion, logic, and credibility by the leader of our country along with other rhetorical devices to enhance his speech.President Obama, in a close comparison on the day of his delivered speech, ties it to the speech spoken by Marin Luther Kings I Have A Dream alludes to establishing more ethos by reminding us (whom he is addressing) that equality is still of great importance to this very day as it was at the time it was written. Both in the importance of unity and structure of language, the president brings us to the past, telling us that freedom had a long line of being taken rather than given. We will write a custom essay sample on President Obamas famously i or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He uses logos to reinforce this idea by referring back to the American Revolution, which is reminding us, in a periodic sentence, that the patriots didnt fight for revenge, but for freedom. Freedom that we would keep safe passing it on to every single generation with it. Just as Martin Luther King had long before in his speech, President Obama springs us back into the present.He states off our countrys accomplishments, starting each achievement of society by together or we to express that it was a collective effort of many, giving the audience (everyone) a sense of pride and acknowledgement of the greatness and achievements that can come out of unity. President Obama begins next by starting his next paragraph with a rebuttal by beginning with But, bringing out a noticeable change of tone. Using deductive reasoning Obama more simply than previously words it out that the Nation cannot work under one individual, but work as a single unit as American people can no more meet the demands of todays world and No single person can train (what we need), Now, more than ever, we must do these things together, as one nation and one people. At this point, it creates a huge sense of unity and direction towards equality and togetherness. President Obama juxtaposes the ending of economic recovery which solidifies hope and of use parallelism we are made for this moment and we will seize it so long as we seize it together. He rallies again, a parallelism which is used frequently throughout the rest of the speech, we, the people, to drive further in establishing togetherness but also builds his presidential ethos, which is important to our freedom and our rights, while still a part of our nations unit as a whole.One of the most notorious parts of the Presidents speech was in support of gay rights. Obama, early in his first term, was heavily criticized by gay organizations for failing to do enough. So, he redeems himself, We, the people, declare today that the most evident of truths – that all of us are created equal – is the star that guides us still; just as it guided our forebears through Seneca Falls, and Selma, and Stonewall, here in the speech through support for gays in the military and for equal marriage rights, but he placed the battle for gay rights, alongside other key civil and womens rights fights. Also said, Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law, and If we are truly created equal, then surely the love we commit to one another must be equal as well, which is significant towards equality among all because no matter skin color, physical features, or what you identify yourself as, it should not matter or compare to any one being.As he implements this form of credibility into the rest of his speech, the president lists the current issues facing our society today, and how we, as one unit, can tackle the issues, pursuing to solve them. He alludes to many events that have taken place in the past year at the time such as the hurricanes that swept away a home, and gun violence in relation to child safety. These real issues help draw the listener back into the reality from the vision of just equality. Finally, President Obama calls for action by reminding us, through anaphora, that our journey is not complete until we are all equal and more open to opportunity, also Obama tells us that it is our task, alluding to the Declaration of Independence, to make these words, rights, these values of life, liberty, and the pursuit of happiness real for every American is a task that we all as Americans will face together as one to conquer for all. Concluding his speech, the president reminds us that we, himself included with the audience are the hope, and the change that is needed to be in action. Obama signs off his address thanking God and proclaiming that may He forever bless these United States of America. For the final push of ethos gathering all emotions at the end to conclude the speech.
