This thesis investigates the constancy of light speed with respect to the light age using an active fiber-based Mach-Zehnder interferometer (MZI) illuminated by sunlight. The original sunlight in one arm, which has the age ...

In an ideal world, unwanted or undesirable effects in a system could and would be completely ignored. In fact, this was the case in mid-80s' PC design when an 80286 microprocessor running at a "blazing" 12 MHz was considered ...

Continuous advances in VLSI technology have led to more complex digital designs and shrinking transistor sizes. Due to these developments, design verification and manufacturing test have gained more importance and 70 % of ...

The growth of broadband Internet access has paved the way for the development of many newer existing technologies. As the costs of implementing broadband access soar, the best alternative will be to use wireless technologies. ...

This thesis describes the design and implementation of an innovative drawing interpretation tool for the sight-impaired. The move towards Graphical User Interfaces in today's computer era presents many challenges to those ...

The World Wide Web (WWW) has become the largest source of Internet traffic, but it was not designed for wireless networks. Documents with large inline images take a long time to fetch over low-bandwidth wireless networks. ...

As the world moves further into the 21st century, the electricity demand worldwide continues to rapidly grow. The power systems that supply this growing demand continue to be pushed closer to their limits. When those limits ...

In recent years, extensive research has been devoted to opportunistically exploiting spectrum in a distributed cognitive radio network. In such a network, autonomous secondary users (SUs) compete with each other for better ...

Software Defined Radios (SDRs) are systems in which components such as filters, modulators, demodulators, etc., typically implemented in hardware are instead implemented in software. Thus, SDR systems shift signal processing ...

Traditional network stacks in monolithic kernels have reliability and security concerns. Any fault in a network stack affects the entire system owing to lack of isolation in the monolithic kernel. Moreover, the large code ...
