Voltage references are fundamental to mixed signal converters which are widely used in elec- tronics. Hence there are signicant advantages in having the voltage reference operate with less power while minimizing area ...

This thesis proposes an MRI-compatible integrated CMOS ampli er that is capable of di- rectly driving an ultrasound transducer for HIFU applications. The output stage of the integrated amplifier operates in class DE mode ...

This thesis described the investigation, construction and testing of two sets of RF coils for their applications in novel lung MRI imaging techniques. In the first part of the thesis, a quadrature-driven birdcage coil for ...

Robotic research has been costly and tremendously time consuming; this is due to the cost of sensors, motors, computational unit, physical construction, and fabrication. There are also a lot of man hours clocked in for ...

One of the driving forces for research in medical sciences is to develop more effective and less intrusive treatments. High Intensity Ultrasound (HIU) is a technique that uses the acoustic field produced by a transducer ...

Simulation of large circuit networks is a CPU-time and memory consuming task. Computer clusters and multi-core processors have become common but algorithms must be parallelizable to fully take advantage of these architectures. ...

The deployment of optical fibre in place of copper cable in access networks has experienced remarkable growth over the past several years due to a wide range of benefits. A major benefit of optical fibre over copper cable ...

Advanced wireless systems, also called fourth generation (4G) wireless systems, such as Mobile Worldwide interoperability for Microwave Access (WiMAX), are developed to provide broadband wireless access in true sense. ...

In recent years, there has been ongoing research on the design of energy-efficient Wavelength Division Multiplexing (WDM) networks. The explosive growth of Internet traffic has led to increased power consumption of network ...

Fiber to the home (FTTH) technology is an attractive solution for providing high bandwidth from the Central Office (CO) to residences and small-and medium-sized businesses. The emergence of Internet Protocol-based communication ...
