A new design technique, based on genetic algorithms, for null steering in Partially adaptive antenna arrays by controlling the minimum number of element positions is presented. This technique shows the possibility of placing nulls in the radiation pattern to suppress interferenc…

In this thesis we show that the finite element error for the high contrast elliptic interface problem is independent of the contrast in the material coefficient under certain assumptions. The error estimate is proved using a particularly technical proof with construction of a sp…
This project investigates the experience of physiological discomfort during travel through an urban environment such as London or New York in winter. The over and underground networks that lace a current metropolis, form vital passages that lead the traveller though a multitude …
The growing demand for faster connection to the Internet service and wireless multimedia applications has motivated the development of broadband wireless access technologies in recent years. WiMAX has enabled convergence of mobile and fixed broadband networks through a common wi…
The marine aquarium trade has played an important role in shaping the ecological state of coral reefs in Indonesia and much of the Asia-Pacific. The use of cyanide by ornamental fishers in Buleleng District, Bali, in the 1980s and 1990s has resulted in a precipitous decline in t…
Research findings suggest low-income African American men report higher stress levels than other groups. Identifying effective strategies for coping with stress is critical for low-income African American men to maintain wellbeing. Many African American men rely on religion as t…
The radio frequency (RF) spectrum is a critical and limited resource for communication and sensing. Due to technological advances, the use of RF devices is increasing exponentially leading to RF crowding, and therefore presenting significant challenges in avoiding interference a…
