Shuangwu Li Phd Thesis: Surface Properties Of Electrospun Poymer Nanofibres
Date: 02-06-2011 17:56Fibrous materials are used in a variety of applications due to their relatively high surface area to volume ratio as well as anisotropic behaviour. Electrospinning is a popular fabrication technique which produces polymer nanofibres with a potentially high molecular orientation. The surface of polymer fibres plays a significant role in many applications thus measurement of the ... read full abstract ››

Optimum Design of a Wind Turbine Blade
Date: 20-05-2011 20:04The project demonstrates the analysis of the wind speed characteristics of a particular wind site and also identifies the optimization of the CL and CD coefficients of a horizontal axis wind turbine blade by an Aerodynamic tool known as XFOIL. The aerodynamic data output given out by XFOIL fluid computational analysis, then allows us to select the MH102, MH104, MH106, MH108 an ... read full abstract ››
Design of a Task-Oriented Hidden Web Crawler
Date: 31-03-2011 10:22The World Wide Web (WWW), the largest and most frequently accessed public repository of information ever developed, contains large number of web pages interconnected through hyperlinks. The WWW can be divided into two parts: Surface Web and Deep Web. The Surface Web refers to the static Web pages that can be crawled and indexed by popular search engines, also termed as Publica ... read full abstract ››
Cantor's Dust and Transmission Errors
Date: 30-03-2011 20:56The dissertation will examine Beniot B. Mandelbrot\'s 1963 paper on his early fractal work in error bursts in transmission lines using a mathematical form known as Cantor\'s Dust. The work will also examine Mandelbrots\' interest in word frquencies as developed from Geoge Zipf\'s \'Principle of Least Effort\'.
Collected Papers on General Telecommunications Theory: A Systems Approach
Date: 30-03-2011 20:08The dissertation will address terrestrial, air and space telecommunications systems utilizing dual intgrated systems employing radio frquency and free space laser technologies for signal transmission. The papers will also introduce the concept of an \'air satellite\' to the dynamics of this system with the use of High Altitude Long Endurance platforms (HALE) for use as a ... read full abstract ››
Development of an Inverse Dynamic Model of Lower Extremities During Gait
Date: 28-03-2011 01:46Dynamic models play an important role in gait studies, providing a tool for study of human locomotion and resulting reaction forces and moments. A three-part model of the lower body was developed through the use of inverse dynamics, to model normal walking in sagittal plane. The objectives of this project were to model normal walking in order to determine joint reaction forces ... read full abstract ››
Security & Surveillance System
Date: 07-01-2011 18:39With the immense increase in crime rate throughout the world, there is an intensive need of security. Every individual feels insecure & wants his personal as well as his surrounding life to be peaceful and secured. A lot of work has been done in this regard. Very efficient security systems have been designed but peace and security is still a question that needs to be answe ... read full abstract ››
Conformal Predictions in Multimedia Pattern Recognition
Date: 19-10-2010 07:44The fields of pattern recognition and machine learning are on a fundamental quest to design systems that can learn the way humans do. One important aspect of human intelligence that has so far not been given sufficient attention is the capability of humans to express when they are certain about a decision, or when they are not. Machine learning techniques today are not yet ful ... read full abstract ››
Efficient use of fossil fuels by implementing mCCHP systems to ensure energy requirements for isolated residencies
Date: 23-07-2010 12:15The development of climate conditions opens new possibilities, such as in the fields of solar and photovoltaic energy. However, the high costs for implementing new technologies and alternative energies represent barriers in their competitiveness against the classic ones. That is why, until developing financially attractive technologies, research is currently focusing on improv ... read full abstract ››
