Timing jitter and phase noise in electronic oscillators

Creator:: Zhang, Chengwei
Abstract:: In the first part of this dissertation, low frequency l/f or flicker noise in the frequency range of Hz to kHz has been identified and demonstrated to be described by temperature fluctuations in heat conduction in bipolar transistors operated at higher power densities. This noise phenomenon is not described by...

Time domain modeling of electromagnetic radiation with application to ultrafast electronic and wireless communication

Creator:: Remley, Catherine A.
Abstract:: A versatile computational technique for improved time domain modeling of electromagnetic radiative systems is demonstrated. Two computational methods are combined: the finite-difference time domain (FDTD) method, a full-wave electromagnetic field solver, and the Kirchhoff surface integral formulation, a spatial transformation technique. The combined FDTD/Kirchhoff technique is shown to increase accuracy...

Quality assessment strategies for multi-camera panorama video

Creator:: Leorin, Simone
Abstract:: New video-conference devices based on omnidirectional multi-camera systems have been emerging in the last few years. These devices require innovative and automated video quality assessment in the earlier stages of their design in order to guarantee competitive product development and quality monitoring. Current quality assessment techniques are not adequate since...

Real-time data quality assessment using linear prediction

Creator:: Rentola, Christopher T. W.
Abstract:: The U.S. Air Force models many naturally occurring phenomena. To validate such models, an automated data collection system is used. Since validation is dependent upon correct data, an inexpensive method to detect erroneous data was investigated. The method uses a Wiener filter to predict values one sample in advance. If...

Hybrid, high speed fault detection based on instantaneous line voltages

Creator:: Ramchandani, Hiranand Balchand
Abstract:: This fault detection scheme is based on sampling the instantaneous phase voltages and checking their sum and magnitude against a specified voltage. Faults on the system cause unbalances and distortion of the phase voltages and currents. The currents and voltages change in magnitude and/or phase position with respect to the...
