Optimization Of Porous-Membranes Utilized In Chlor-Alkali Technology Via The Use Of Porosity And Electrochemical Impedance Spectroscopy, Jo Ann Jackson May 1996

Optimization Of Porous-Membranes Utilized In Chlor-Alkali Technology Via The Use Of Porosity And Electrochemical Impedance Spectroscopy, Jo Ann Jackson

Electronic Dissertations and Theses

A fundamental understanding of porous diaphragm membrane utilized by Dow Chemical Company in the production of chlorine gas and caustic soda, is integral to optimizing its performance. Several factors have been identified as integral components in this effort to optimize the chlorine cell diaphragm. Among these components are the diaphragm's porosity, pore size, thickness and tortuosity. Several methods have been utilized in an effort to determine not only the desired values of each of these variables but also to develop ways of achieving these desired values. Because not all of these variables can be measured directly, other methods of collecting …

Isolation From Soil Microorganisms That Are Inhibitory To Wheat Seeding Pathogens, Kynita Wilson-Humphrey May 1996

Isolation From Soil Microorganisms That Are Inhibitory To Wheat Seeding Pathogens, Kynita Wilson-Humphrey

McCabe Thesis Collection

Many diseases caused by bacteria, viruses, or fungi are responsible for the ruin of a great number of crops annually. At present, many of these crops are being treated for diseases by synthetic or man-made chemicals. Some of the chemicals have been proved to have adverse effects on the environment, including humans and animals. Very few non-chemical means are available to farmers at this time to control these pathogens. This is due to the fact that many of the means of control have little effect against the pathogens or diseases. This research attempts to isolate microorganisms from the soil which …

Probabilistic Analysis Of The Median Rule: Asymptotics And Applications, Anil Ravindran Menon, Kishan Mehrotra, Chilukuri K. Mohan, Sanjay Ranka May 1996

Probabilistic Analysis Of The Median Rule: Asymptotics And Applications, Anil Ravindran Menon, Kishan Mehrotra, Chilukuri K. Mohan, Sanjay Ranka

Electrical Engineering and Computer Science - Technical Reports

The solution of integer optimization problems by relaxation methods consists of three parts. First, the discrete problem is converted into a continuous optimization problem, which is generally more tractable. Second, the relaxed problem is solved efficiently, yielding a optimal solution in the continuous space. Finally, an assignment procedure is used to map this solution to a "suitable" discrete solution. One heuristic - we call it the relaxation heuristic - that often guides the choice and design of assignment algorithms is: "given a continuous optimal solution, the corresponding integer optimal solution is likely to be nearby" (with respect to some well …

On Quaternionic Pseudo-Random Number Generators, Gary R. Greenfield May 1996

On Quaternionic Pseudo-Random Number Generators, Gary R. Greenfield

Department of Math & Statistics Technical Report Series

There is no dearth of published literature on the design, implementation, analysis, or use of pseudo-random number generators or PRNGs. For example, [6] [7] [14] and the references therein, provide a broad overview and firm grounding for the subject. This report complements and elaborates upon the work of McKeever [9], who investigated PRNGs constructed in a non-commutative setting with the target application being so-called cryptographically secure PRNGs as discussed in [12] or [13]. Novel "solutions" to the problem of designing cryptographically secure PRNGS continue to be proposed [1] [2] [10] [15], so despite the caution and skepticism required, the area …

Dartflow: A Workflow Management System On The Web Using Transportable Agents, Ting Cai, Peter A. Gloor, Saurab Nog May 1996

Dartflow: A Workflow Management System On The Web Using Transportable Agents, Ting Cai, Peter A. Gloor, Saurab Nog

Computer Science Technical Reports

Workflow management systems help streamline business processes and increase productivity. This paper describes the design and implementation of the DartFlow workflow management system. DartFlow uses Web-browser embedded Java applets as its front end and transportable agents as the backbone. While Java applets provide a safe and platform independent GUI, the use of transportable agents makes DartFlow highly flexible and scalable. This paper describes the design and implementation of DartFlow, as well as a workflow application that exploits DartFlow's agent-based design.

The Galley Parallel File System, Nils Nieuwejaar, David Kotz May 1996

The Galley Parallel File System, Nils Nieuwejaar, David Kotz

Computer Science Technical Reports

Most current multiprocessor file systems are designed to use multiple disks in parallel, using the high aggregate bandwidth to meet the growing I/O requirements of parallel scientific applications. Many multiprocessor file systems provide applications with a conventional Unix-like interface, allowing the application to access multiple disks transparently. This interface conceals the parallelism within the file system, increasing the ease of programmability, but making it difficult or impossible for sophisticated programmers and libraries to use knowledge about their I/O needs to exploit that parallelism. In addition to providing an insufficient interface, most current multiprocessor file systems are optimized for a different …

Hde 233517: Lithium And Excess Infrared Emission In Giant Stars, Francis C. Fekel, Richard A. Webb, Russel J. White, Benjamin Zuckerman May 1996

Hde 233517: Lithium And Excess Infrared Emission In Giant Stars, Francis C. Fekel, Richard A. Webb, Russel J. White, Benjamin Zuckerman

Information Systems and Engineering Management Research Publications

Recent studies have identified a small class of moderately rapidly rotating, chromospherically active, single giants, some of which are lithium rich. We present evidence suggesting the peculiar K-type star HDE 233517 is one such object. Previously, HDE 233517 has been suggested to be a young star, consistent with its large far-infrared excess and our log ε(Li) ~ 3.3. However, our high-resolution spectroscopic observations show it is likely a single, post-main-sequence K2 giant with v sin i = 15 km s-1 and modest Ca II H and K emission. The giant status of HDE 233517 is determined directly from luminosity-sensitive line …
