An Assessment Of A Black Community: Stress Effects Relating To Hypertension, Patricia Edwards Parrish

Theses

The north side of St. Louis was chosen by the author for many reasons. Perhaps the most important reason is the many stressors within the black community which attribute to health problems such as hypertension. Not only is hypertension more prevalent in blacks than whites, but it is also more severe (Butcher & Allen, Dec. 1989). The vital statistics indicate that the mortality risk in black patients with hypertension is approximately two to six times more than in whites.

Some other reasons for its selection are: This community, according to the Sixth District Police Department (Personal Communication, Jan., 1989), is …

Drag Reduction In Pipe Flows With Polymer Additives, Daniel W. Grabowski

Theses

Polyethylene Oxides (PEO) with molecular weights of 4 and 6 million and a Polyacrylamide (PAM) with a molecular weight of 15 million, were added to a turbulent pipe flow (15000 < Re < 50000) for drag reduction. The polymer was injected directly into the test section in one scenario, premixed in a tank and then pumped through the test section in the second. The injection addition method was found to be optimal because it subjected the polymer to lower amounts of shear stresses than the premixed addition method. A maximum of 75% reduction in drag was obtained. Even trace concentrations, as low as 2.5 WPPM (weight parts per million) , resulted in as high as 37% reduction in drag. Long thin high molecular weight polymers (PEO) were more effective than coiled high molecular weight polymer (PAM) . For the same molecular structure it was found that the polymer with heavier molecules had better drag reducing characteristics. The polymer with coiled molecules, however, is more resistant to shear stresses which break down the polymer into smaller less effective molecules. It was found that there is a critical concentration for the greatest drag reduction. This concentration is approximately 375 WPPM (.0375% byweight) of PEO for the injection method, and 500 WPPM of PEO for the premixed method. At greater concentrations, the viscosity of the solution increases such that the drag reduction characteristics of the polymer can no longer compensate.

Parallelism In Declarative Languages, Catherine Eleftherios Chronaki

Theses

Imperative programming languages were initially built for uniprocessor systems that evolved out of the Von Neumann machine model. This model of storage oriented computation blocks parallelism and increases the cost of parallel program development and porting. Declarative languages based on mathematical models of computation, seem more suitable for the development of parallel programs. In the first part of this thesis we examine different language families under the declarative paradigm: functional, logic, and constraint languages. Functional languages are based on the abstract model of functions and (lamda)-calculus. They were initially developed for symbolic computation, but today they are commonly used in …

Speech Intelligibility Estimation Via Neural Networks, Stephen Knight

Theses

Current methods of speech intelligibility estimation rely on the subjective judgements of trained listeners. Accurate and unbiased intelligibility estimates have a number of procedural and/or methodological constraints including the necessity for large pools of listeners and a wide variety of stimulus materials. Recent research findings however, have shown a strong relationship between speech intelligibility estimates and selected acoustic speech parameters which appear to determine the intelligibility of speech. These findings suggest that such acoustic speech parameters could be used to derive computer-based speech intelligibility estimation, obviating the procedural and methodological constraints typically associated with such estimates. The relationship between speech …

Reasoning With Visual Knowledge In An Object Recognition System, Christine Wojnowski

Theses

The impact of artificial intelligence on computer vision has provided various perspectives and approaches to solving problems of the human visual system. Some of the symbolic processing and knowledge-based techniques implemented in vision systems represent a meaningful extension to the low-level, algorithmic processing which has been emphasized since the advent of the computer vision field. The higher-level processes attempt to capture the essence of visual cognition, specifically by encompassing a model of the visual world and the reasoning processes that manipulate this stored visual knowledge and environmental cues. This thesis includes a discussion of existing computer vision systems surveyed from …

Enhancements To The Xns Authentication-By-Proxy Model, Peter D. Wing

Theses

Authentication is the secure network architecture mechanism by which a pair of suspicious principals communicating over presumably unsecure channels assure themselves that each is that whom it claims to be. The Xerox Network Systems architecture proposes one such authentication scheme. This thesis examines the system consequences of the XNS model's unique proxy variant, by which a principal may temporarily commission a second network entity to assume its identity as a means of authority transfer. Specific attendant system failure modes are highlighted. The student's associated original contributions include proposed model revisions which rectify authentication shortfalls yet facilitate the temporal authority transfer …

This study investigates a number of these approaches including Bayesian Probability, Mycin Certainty Factors, Dempster-Shafer Theory of Evidence, Fuzzy Set Theory, Possibility Theory and non monotonic logic. Each of these theories and their underlying formalisms are explored by means of examples. The discussion concentrates on a …

Internetworking: An Analysis And Proposal, Gary M. Diana

Theses

As the number of computer networks has grown, so has the desire for users on these networks to communicate with each other, thus the need for internetworking. Unfortunately, many of these networks were not designed with internetworking capabilities in mind. The internetworking facilities offered by a typical network range from non-existent to state of the art. Two major efforts towards internetworking are the DARPA Internet protocols and the OSI Internetworking protocols. The goals of this thesis are to acquaint the reader with the qualities which are desired in an internetworking scheme, to describe how internetworking is accomplished currently, and how …

Free Space Laser Communications On The Macintosh Computers, Sohrab Modi

Theses

Lasers have proved their reliability in high speed communications through fibre optics. The disadvantage with fibre optics is the high cost and the need for a cable to connect the sender to the receivers, hence making it impractical to have fibre optic cables over large distances. The move today is to communicate between points with a free space laser ( ie. a beam unbounded by cables). Semi conductor lasers as used in fibre optic cables are generally not strong enough to communicate over very large distances. Hence a high power laser is used with a modulation technique to transmit this …

It is shown that the dynamic response of the actual scan system can be predicted quite well using such simulations. Furthermore, these simulations can aid …

Distributed Object-Oriented Discrete Event Simulation, Barbara Hendry

Theses

This paper presents criteria for an 'ideal' simulation language, compares four traditional simulation languages to this ideal and concludes that an object-oriented approach to simulation comes closer to the ideal than the traditional procedural approach. It also examines how the object-oriented approach can be very beneficial for distributing a simulation problem among several machines. A distributed object-oriented package is described and a manufacturing example written and explained using this package.

Mechanical Properties Of Polymeric Packaging Films After Radiation Sterilization, Viriya Pungthong

Theses

The use of radiation as a sterilization process is increasing. The well-developed technology of the radiation sterilization as applied to medical devices has assured the food industry that the process is reliable. Due to the food industry's possibility of widespread use, it is especially crucial that an appropriate packaging material be chosen so that its integrity is maintained after irradiation. This is because the commercial food packaging process carries products through more rigorous paths and channels than medical supplies. Many polymers used in the medical field show various degrees of degradation after radiation exposure, which can be determined either by …
