A new variation of the array gain optimization problem has arisen in the study of microwave arrays used for hyperthermia, the heating of biological tissue. For a given array configuration and arbitrary medium, we show how ...

The ability to walk can be severely compromised by a lower-limb amputation, which can have long-reaching consequences to the individual’s health and safety. It has been reported that the high incidence of lower back pain ...

This thesis contains three investigations examining gait variability in people with multiple sclerosis (MS), which is a neurological disease that can result in significant walking impairment. Gait variability, i.e. ...

The AlGaN/GaN high electron mobility transistor (HEMT) is a promising candidate for microwave applications due to its high power and low noise characteristics at such frequencies. As a result of improved material growth ...

Together with the massive and rapid evolution of computer networks, there has been a surge of research interest and activity surrounding network security recently. A secure network has to provide users with confidentiality, ...

Developments in information technology have necessitated dynamic distributed real-time allocation of computational and network resources. We consider the use of market mechanisms to regulate a set of autonomous agents that ...

Carefully crafted computer worms such as Stuxnet and recent data breaches on retail organizations (e.g., Target, Home Depot) are very sophisticated security attacks on critical cyber infrastructures. Such attacks are ...

In this thesis, we provide mathematical formulations for and investigate a number of problems that arise in the security of some emerging wireless technologies. First, we address the problem of secure communication between ...
