Importance Of Major Research Interests - 1039 Words

Major Research Interests Because of my education in aerospace engineering and materials science at Caltech and China, civil engineering and mechanical engineering faculty experience in the US, my research is typically interdisciplinary. Mainly, my research is focused on mechanics and designs of advanced materials and structures, especially multi-scale relationships between nano/micro-scale phenomena and macro-scale properties. My current interests/projects involve both extremely small time-scales and length-scales in very different research areas. 1. Cost-effective Layered Material Systems to Reduce Property Damage during Hurricanes Recent hurricanes led to significant loss to residents and insurance companies. Since replacing a†¦show more content†¦The DTMI damage reducing mechanisms were discovered through some quantitative investigations. For example, the maximum impact force on a thick polymer system featuring a DTMI was reduced by 60%, and energy absorption was increased by 130%. We plan to conduct systematic basic research to understand the effects of the bonding strength and interface thickness on crack arrest, to explore novel layered material designs for achieving low costs. 2. Impact-resistant Composite Designs for Aircraft, Automobile and Wind Turbines A major shortcoming of wind energy technology is the failure rate of composite blades is up to 20% due to bird/bat strike as shown in Figure 2. On the other hand, one major US Energy Company pleaded guilty to killing 14 eagles and 149 other birds due to their wind turbines ($1M fine, or $6,000/bird!). Therefore, we plan to employ â€Å"damage-trap material interface (DTMI) design† to reduce not only the impact damage of composite blades, but also the bird/bat death rate, since the maximum impact force acting on birds will decrease after special thin interface layers are placed between layered composites based on our preliminary impact experiments (impact speed up to 50 m/s). Our major goal is to significantly improve impact resistance and durability of composite structures for wind blades, Boeing 787, and BMW i3 or future composite aircraft, ships and cars. Meanwhile, we are developing an efficient approach to combine nanoindentationShow MoreRelatedThe Ethical Principles Of Ethics852 Words   |  4 Pagesall nations and cultures, parents always teach their children the importance of truthfulness, forgiveness and honesty and all of that consider as parts of morality. Thus, in individual level, morality is significant, therefore, in organizational level morality and integrity should be at the same level of importance. It is generally believed that ethical policies are highly necessary in every organisation or association. Research environment is one of the areas, which highly require some moral regulationRead MoreManaging A Firm Based On Past Oriented Financial Statements1718 Words   |  7 Pagesreporting became the central theme as the International Financial Reporting Standards (IFRS) took effect on January 1st, 2005. The aim of the new standards was to improve the financial statements‟ quality, comparability, and transparency, which meant major changes to the reporting of European companies (Daske et al., 2008). It was expected that along with IFRS and the rapidly changing business environment, the reporting would adapt from the traditionally backward-looking and numerical information towardsRead MoreKey Components Of Reading As A Student s Interest863 Words   |  4 Pagesto become better a reading teacher. One of the major components of the class that I have learned and fully underst and are the five major components of reading which include phonemic awareness, phonics, vocabulary, comprehension, and fluency. I was able to see the importance of each one of those and how they consecutively build off one another. Another major take away from this class is the importance of taking the time to learn a student’s interest and also sharing yours with them. Not only is thisRead MoreFinancial Analysis Essay1238 Words   |  5 PagesIs the Industry’s Analyst Research Useful for Investment Decisions? The primary role of the research analysts is to study the publicly traded companies and pass recommendations based on their financial securities, future growth potentials, and profit generation potentials. These recommendations influence economic activities in the contemporary industries. For instance, such recommendations can affect stock prices, especially if they are broadcasted to a large population. People’s decisions to purchaseRead MoreWhy Is College Pilgrimage?983 Words   |  4 PagesFor thousands of years, humans have travelled all across the world in search of enlightenment and spiritual improvement. These journeys are  seen in every major religion; from the Islamic pilgrimage of Mecca to the Hindu pilgrimage of the Himalayan Char Dham. The act of embarking on a pilgrimage is never an easy undertaking; particularly when that includes the reliance on relationships that have not yet been  forged. This connection with culturally different individuals develop an un equivocal senseRead MoreDefinitions And Objectives Of Real Estate1628 Words   |  7 Pagesused in real estate closing meeting. For over a long time research conducted by scholars on these terminologies has shown that real estate business can directly or indirectly be determined by adhering to such terms. Although there are many such terminologies used in closing meeting of real estate, this paper will focus on just a few terminologies which include the deed of title, APR and contingency, this paper also aims to show the importance of these terminologies, its advantages, disadvantages andRead MoreMy Interest Gravitated Towards Commercial Law785 Words   |  4 Pageshelped me understand the universal importance and impact of the law to any society. The ability of the law, lawyers and judges to always evolve, analyze and execute laws accurately and precisely, appealed to my impressionable mind. After this experience, there was little doubt in my career choice: I wanted to be a pract icing legal professional.    I studied my Bachelors of Law at the University of Kent in the United Kingdom.
