A Circuit Layout Methodology Incorporating Machine Learning, A. Ford, R. Fujii Mar 1990

A Circuit Layout Methodology Incorporating Machine Learning, A. Ford, R. Fujii

Department of Electrical and Computer Engineering Technical Reports

We describe the use of a form of machine learning which makes efficient use of time and computing resources for developing and optimizing a transistor level IC layout. Our learning system abstracts new knowledge from examples it is provided and incorporates this new knowledge into a generalized solution graph. This generalized solution graph contains information about layout topologies known to the system

Evaluation Of The Cost-Effectiveness Of Pavement Surface Maintenance Activities, Ibrahim Moussa Mouaket, Abdullah Al-Mansour, Kumares C. Sinha Jan 1990

Evaluation Of The Cost-Effectiveness Of Pavement Surface Maintenance Activities, Ibrahim Moussa Mouaket, Abdullah Al-Mansour, Kumares C. Sinha

JTRP Technical Reports

This study covers pavement surface maintenance on three surface types: rigid, flexible and composite (asphalt overlay on rigid pavement). It addresses 3 main issues as follows: 1) Do routine maintenance activities make a difference in terms of pavement serviceability? If yes, how much? 2) Are chip and sand seal coating cost-effective? What is their optimal timing? 3) What management criteria should be used as a guide to make seal coating decisions on specific roadways? In resolving Issue #1, a stratified 2-stage sample of observational data was used in a statistical before/after comparison. SAS-General Linear Model was used due to its …

Simulation Of Free Radical Reactions In Biology And Medicine: A New Two-Compartment Kinetic Model Of Intracellular Lipid Peroxidation, Charles F. Babbs, Melissa Gale Steiner Jan 1990

Simulation Of Free Radical Reactions In Biology And Medicine: A New Two-Compartment Kinetic Model Of Intracellular Lipid Peroxidation, Charles F. Babbs, Melissa Gale Steiner

Weldon School of Biomedical Engineering Faculty Publications

To explore mechanisms of free radical reactions leading to intracellular lipid peroxidation in living systems, we developed a computational model of up to 109 simultaneous enzymatic and free radical reactions thought to be involved in the initiation, propagation, and termination of membrane lipid peroxidation. Rate constants for the various reactions were obtained from the published literature. The simulation model included a lipid membrane compartment and an aqueous cytosolic compartment, between which various chemical species were partitioned. Lipid peroxidation was initiated by the iron-catalyzed, superoxide-driven Fenton reaction. A "C"-language computer program implemented numerical solution of the steady-state rate equations for concentrations …

Tardis: A Numerical Simulation Package For Drive Systems, W. Suwanwisoot, C. M. Ong Jan 1990

Tardis: A Numerical Simulation Package For Drive Systems, W. Suwanwisoot, C. M. Ong

Department of Electrical and Computer Engineering Technical Reports

TARDIS is a digital computer simulation package originally intended to simulate drive systems. Its versatility has proved to be very useful in other areas as well. It is designed to replace the functionality of analog computers so that the user who cannot afford to have one can use the program on a personal or mainframe computer. The author believes that it is one of the most efficient and accurate simulation programs of its kind at this point even though not all of its potential has been exploited to. the fullest. It can handle index 0 and 1 differential-algebraic systems with …


Automatic Parallelization Of Database Queries, Myong H. Kang, Henry G. Dietz Jan 1990

Automatic Parallelization Of Database Queries, Myong H. Kang, Henry G. Dietz

Department of Electrical and Computer Engineering Technical Reports

Although automatic parallelization of conventional language programs is now widely accepted, relatively little emphasis has been placed on automatic parallelization of database query programs (sometimes referred to as “multiple queries” ). In this paper, we discuss the unique problems associated with automatic parallelization of database programs. From this discussion, we derive a complete approach to automatic parallelization of database programs. Beside integrating a number of existing techniques, our approach relies heavily on several new concepts, including the concepts of “algorithm-level” analysis and hybrid static/dynamic scheduling.


Image Segmentation Using Human Visual System Properties With Applications In Image Compression, Heidi A. Peterson, Sarah A. Rajala, Edward J. Delp Jan 1990

Image Segmentation Using Human Visual System Properties With Applications In Image Compression, Heidi A. Peterson, Sarah A. Rajala, Edward J. Delp

Department of Electrical and Computer Engineering Technical Reports

In order to represent a digital image, a very large number of bits is required. For example, a 512 X 512 pixel, 256 gray level image requires over two million bits. This large number of bits is a substantial drawback when it is necessary to store or transmit a digital image. Image compression, often referred to as image coding, attempts to reduce the number of bits used to represent an image, while keeping the degradation in the decoded image to a minimum. One approach to image compression is segmentation-based image compression. The image to be compressed is segmented, i.e. the …

Free Radicals And The Etiology Of Colon Cancer, Charles F. Babbs Jan 1990

Free Radicals And The Etiology Of Colon Cancer, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

This hypothesis paper reviews diverse evidence suggesting that intracolonic production of oxygen radicals may play a role in carcinogenesis. The hypothesis began to evolve when the author made the chance discovery that 1/10,000 dilutions of feces generated detectable quantities of highly reactive hydroxyl radicals (HO). The rate of HO formation, detected using DMSO as a molecular probe, was quite remarkable, corresponding to that which would be produced by over 10,000 rads of gamma irradiation per day, absorbed in the periphery of the fecal mass adjacent to the mucosa. The relatively high concentrations of iron in feces, together with the ability …
