Quantum Transport With Dissipation: Linear And Non-Linear Response, Supriyo Datta, Michael J. Mclennan

Department of Electrical and Computer Engineering Technical Reports

We present a quantum transport equation derived under the simplifying assumption that the inelastic scattering is caused by uncorrelated point scatterers, such as magnetic impurities. While this assumption is not always realistic, we believe that the model can be used to describe much of the essential physics of quantum transport in mesoscopic systems. This assumption allows us to write a quantum transport equation that involves only the diagonal elements of the density matrix which we use to define a distribution function f(r; E). The kernel of this integral equation is calculated from the Schrodinger equation and contains all quantum interference …

Basic Studies Of Iii-V High Efficiency Cell Components, M. S. Lundstrom, M. R. Melloch, R. F. Pierret, M. S. Carpenter

Department of Electrical and Computer Engineering Technical Reports

The objective of the project is to raise the understanding of dark current mechanisms in GaAs-related solar cells to a level comparable to that of silicon cells. Motivation for this work arises from the observation that much of the progress in crystalline silicon cell performance has occurred as a result of a very deep knowledge of the physics controlling the cell’s dark current. Based on this knowledge, new cell structures evolved to suppress dominant dark current mechanisms. A comparable level of knowledge of GaAs cell device physics does not yet exist, but will be essential if cell performance near the …

Model For An Intelligent Operating System For Executing Tasks On A Reconfigurable Parallel Architecture, C. Henry Chu, Edward J. Delp, Leah H. Jamieson, Howard Jay Siegel, Frank J. Weil, Andrew B. Whinston

Department of Electrical and Computer Engineering Technical Reports

Parallel processing is one approach to achieve the large computational processing capabilities required by many real-time computing tasks. One of the problems that must be addressed in the use of reconfigurable multiprocessor systems is matching the architecture configuration to the algorithms to be executed. This paper presents a conceptual model that explores the potential of artificial intelligence tools, specifically expert systems, to design an Intelligent Operating System for multiprocessor systems. The target task is the implementation of image understanding systems on multiprocessor architectures. PASM is used as an example multiprocessor. The Intelligent Operating System concepts developed here could also be …

Symbolic Analysis Of Large-Scale Networks, M. M. Hassoun, P. M. Lin

Department of Electrical and Computer Engineering Technical Reports

A new approach to the problem of symbolic circuit analysis of large-scale circuits is presented in this report. The methodology has been implemented in a computer program called SCAPP (Symbolic Circuit Analysis Program with Partitioning). The method solves the problem by utilizing a hierarchical network approach and the sequence of expressions concept rather than a topological approach and the single expression idea which have dominated symbolic analysis in the past. The method employs further modifications to the modified nodal analysis (MNA) technique by allowing ideal opamps in the matrix formulation process and introducing the reduced modified analysis matrix (RMNA). The …

Continuing Education At Purdue University: The First Hundred Years (1874–1974), Frank K. Burrin

Continuing Education

The History of Continuing Education at Purdue: The First Hundred Years (1874–1974) was compiled from documents and manuscripts left by Dr. Frank K. Burrin. After his retirement, Dr. Burrin set himself the task of writing a coherent, full-length history of Purdue's contributions to continuing education. Unfortunately, his project was left incomplete at his death. Fortunately, his friends and colleagues at the university were unwilling to let his dream die with him. The present monograph is the result of their concern.

The fragmentary nature of the surviving manuscript made it impossible either to reconstruct Dr. Burrin's original plan for the organization …

The Pseiki Report—Version 2. Evidence Accumulation And Flow Of Control In A Hierarchical Spatial Reasoning System, K. M. Andress, A. C. Kak

Department of Electrical and Computer Engineering Technical Reports

A fundamental goal of computer vision is the development of systems capable of carrying out scene interpretation while taking into account all the available knowledge. In this report, we have focused on how the interpretation task may be aided by expected-scene information which, in most cases, would not be in registration with the perceived scene. In this report, we describe PSEIKI, a framework for expectation-driven interpretation of image data. PSEIKI builds abstraction hierarchies in image data using, for cues, supplied abstraction hierarchies in a scene expectation map. Hypothesized abstractions in the image data are geometrically compared with the known abstractions …

Physics And Modeling Of Submicron Devices. Annual Report: August I, 1987 - July 31, 1988, Supriyo Datta, Mark S. Lundstrom, Amitava Das, H. Bob Frohne, Michael J. Mclennan

Department of Electrical and Computer Engineering Technical Reports

The work described in this report is directed at understanding quantum transport phenomena in sub-micron heterostructure devices, at developing computational techniques for modeling such devices, and at applying these techniques to develop new device concepts. During the past year we have (l) applied a previously developed collisionless quantum device model (SEQUAL) and Monte Carlo model (DEMON) to the design and study of heterojunction bipolar transistors (Chapter 2); (2) developed a technique for the analysis of arbitrarily shaped quantum devices with elastic scattering (Chapter 3); and (3) developed an approach for incorporating inelastic dissipative processes in quantum transport theory (Chapter 4). …

Wage Survey Of Road And Street Employees In Indiana Counties And Cities, Herpicc

Indiana Local Technical Assistance Program (LTAP) Publications

Wages, benefits and insurance plans for employee classifications common to road and street maintenance organizations are reported in this publication. The figures were obtained from a March 1988 questionnaire sent to all Indiana County Highway Departments and from the "Indiana Municipal Salaries, Wages and Fringe Benefits, 1988" published by the Indiana Association of Cities & Towns.

The information in this publication is intended to assist the local road and street agencies in developing the wage plans for next years budget by providing comparative information from other organizations in the state. Exact duties and responsibilities vary and are not reflected in …

Guide To Revenue Calculations: Local Option Highway User Tax 1988, Herpicc

Indiana Local Technical Assistance Program (LTAP) Publications

This guide is provided to explain the output generated by the computer programs and to suggest ways in which the results can be adapted to specific LOHUT proposals before a County Council. The 1988 LOHUT revenue projections are of special interest because of House Enrolled Act Number 1295. This act (IC 8-11-5) granted each county authority to bond for county roads or bridges, but only if a county has first adopted a LOHUT -- the excise surtax (IC 6-3.5-4) and wheel tax (IC 6-3.5-5).

HERPICC neither endorses nor opposes passage of a LOHUT. The revenue projections it provides are intended …
