Conjugate-Gradi3nt Neural Networks In Classification Of Multisource And Very-High-Dimensional Remote Sensing Data, Jon A, Benediktsson, Philip H. Swain, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

Application of neural networks to classification of remote sensing data is discussed. Convkntional tw+layer backpropagation is found to give good results in ~lassificationo f remote sensing data but is not efficient in training. A more efficient variant, based on conjugate-gradient optimization, is used for classification of nsultisource remote sensing and gedgraphic data and veryhigh- dimensional data. The conjugate-gradient neural networks give excellent performance in classification of multisource data but do not compare as well with statistical methods in classifictition of very-high-dimensional data.

Low Temperature Silicon Selective Epitaxial Growth(Seg) And Phosphorous Doping In A Reduced-Pressure Pancake Reactor, Weichung Wang, Jack Denton, Gerold W. Neudeck

Department of Electrical and Computer Engineering Technical Reports

Pancake reactors operated at low temperatures and reduced-pressures have been used for silicon selective epitaxial growth (SEG). In general, dichlorosilane (DCS) is the silicon source gas, hydrogen is the carrier gas, and HCl prevents the formation of polysilicon on the silicon dioxide. An investigation of growth rate, uniformity, and doping characteristics of SEG silicon grown at reduced pressures between 40 and 150 Torr and temperatures between 820°C and 1020°C in a pancake reactor is presented. The dependences of growth rates and uniformities on growth temperatures, pressures, and doping were studied. Improvement in thickness uniformity across the wafer was achieved by …

A Study Of Numerical Integration Techniques For Use In The Companion Circult Method Of Transient Circuit Analysis, Charles A. Thompson

Department of Electrical and Computer Engineering Technical Reports

Circuit transient analysis packages such as SPICE and EMTP are very widely used, but detailed information on the internal structure and error characteristics for these software packages is lacking. Both SPICE and EMTP rely on numerical integration to approximate the transient response of circuit elements. The numerical integration methods used in the packages are not necessarily the most accurate approximations to the actual response of a circuit. The study of these numerical integration methods and their error characteristics is the focus of this thesis. Comparisons are made between several methods in terms of accuracy and stability as well as algorithm …

Some Topics On The Deregulation Of The Power Industry In The United States, K. Karagory, P. Lyons, R. Ramabhadran, P. Ruby, C. Thompson

Department of Electrical and Computer Engineering Technical Reports

This is a student report prepared for EE635, Economic Operation and Control of Interconnected Power Systems, for the Spring, 1992 semester at Purdue University. The assigned topic to the class was to discuss and describe some aspects of the "deregulation" of the United States power industry. The first chapter by Charles Thompson deals with the wheeling and transmission losses due to power exchange. This topic has been a main bottleneck for accountants and engineers in fully realizing advantages in a deregulated power environment. Perhaps the core of deregulation, the Public Utility Regulatory Policies Act (PURPA), is discussed and described by …
