Creator:: Al-Shahrani, Ali
Abstract:: The detection of motor faults at their incipient stage is of prime importance to any industrial plant. The introduction of adjustable speed drives has improved the control and the efficiency of induction motors, however, this has changed the nature of motor faults and how they can be detected. Current signature...

Creator:: Al Tuaimi, Hamad A.
Abstract:: Preventative motor fault detection is of prime importance for modern plant management. During research into rotor faults, performed at the Motor Systems Resource Facility (MSRF), an optimized rotor fault detection and classification method was proposed. In critical process applications, the suggested method would provide the foundation for continually monitoring a...

Creator:: Natesan, Peroly
Abstract:: A comparison and analysis of jitter for five different architectures of ring oscillators using a novel simulation technique developed by Professor Forbes' group is presented. Ring oscillators have become an essential building block in many digital and synchronous communications system due to their integrated nature and are widely used in...

Creator:: Ohm, David R.
Abstract:: The problem of locating a signal source, or an emitter, has many civilian and military applications, such as communication regulations enforcement, military reconnaissance, and search-and-rescue operations. Many of the most widely used emitter location methods rely on the accurate and robust estimation of the differential time delay, or time-difference-of-arrival (TDOA),...

Creator:: Myers, Charles Grant
Abstract:: Pipeline analog-to-digital converters (ADCs) have long been used in high-speed systems for power-efficient data conversion. Broadband communication and video processing systems are placing high demands on converter accuracy and speed (above 14 bits and in the multiple-MHz range). The increasing converter requirements coupled with lower supply voltages in modern processes...

Creator:: Kandukuri, Ajay
Abstract:: Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...
