Training Arbitrarily Connected Neural Networks with Second Order Algorithms
(2008-09-09)
Neural networks have been an active area of research and application for many years. Today they are gaining popularity with the growing processing power of modern computers. With neural networks gaining popularity comes ...
Numerical Modeling of Very Thin Dielectric Materials
(2008-09-09)
In this work, a Method of Moments (MoM) formulation is presented for the
numerical solution of very thin dielectric materials in the frequency domain. The
dielectric material is represented by a triangular mesh and a ...
Doubly-Selective Channel Estimation and Equalization Using Superimposed Training and Basis Expansion Models
(2008-09-09)
Owing to multipath propagation and Doppler spread, typical wireless channels are both frequency- and time-selective (doubly-selective). In this dissertation, we concentrate on channel estimation and equalization over ...
Built-In Self Test for Regular Structure Embedded Cores in System-on-Chip
(2008-09-09)
Miniaturization and integration of different cores onto a single chip are increasing
the complexity of VLSI chips. To ensure that these chips operate as desired, they
have to be tested at various phases of their development. ...
Radial Deblurring with FFTs
(2008-09-09)
Radial blurring (sometimes called zoom blurring) of an image occurs when a camera acquires an image while traveling at a high rate of speed towards an object. Removing this blur is a challenging problem because it is a ...
Power and Performance Optimization of Static CMOS Circuits with Process Variation
(2008-09-09)
With the continuing trend of technology scaling, leakage power has become a main contributor to power consumption. Dual threshold (dual-Vth) assignment has emerged as an efficient technique for decreasing leakage power. ...
Development of an Autonomous Mobile Robot-Trailer System for UXO Detection
(2008-09-09)
The process of finding and removing unexploded ordnance (UXO) from contaminated sites is an expensive and time consuming task. In this thesis, an autonomous mobile robot-trailer system is developed for this purpose. It ...
Design and Implementation of a Software Defined Radio Receiver for AM Band
(2008-09-09)
Since the mid-1990s, the radio industry has actively focused on implementing more and more radio functions in the digital domain. This has been furthered by availability of high speed, high performance data converters and ...
Nonlinear Control and Design Methodologies for Electrostatic MEMS Devices
(2008-09-09)
A method to extend the travel range of electrostatically actuated MEMS device is presented. A gap closing actuator (GCA) is used to demonstrate the method. An output (position)feedback controller is presented, along with ...
Improved RF Noise Modeling for Silicon-Germanium Heterojunction Bipolar Transistors
(2008-09-09)
Accurate radio frequency (RF) noise models for individual transistors
are critical to minimize noise during mixed-signal analog and RF circuit design.
This dissertation proposes two improved RF noise models
for SiGe ...
