Lei Rimana "She Stays", Keith Watson

Theses

My concept is to re-evaluate and advance personal communication aids, generally, but not entirely, in the form of greeting cards, to a new level of interest and signification. The goal is to eliminate the passive viewer, and have the individual actively participate in the presentation. The computer-based, interactive media project is designed around three-dimensional sculptures, which serve as "narrators," and put back the one-to-one interaction that is so often missing in non-verbal greetings. In combining technology with more traditional storytelling techniques, it will develop and express a personal message that will help reinforce the intent of the message by becoming …

The overall goal of this thesis is to try to bring out the emotions of fear, frustration, madness, and humor from the users. The secondary goal is to explore the limit of user …

Modeling Ventricular-Vascular Coupling In The Developing Embryo, Michael Bauman

Theses

Congenital cardiovascular malformations are one of the major contributors to infant mortality in the United States today. Defects in the cardiovascular system are evident at very early stages in the developing embryo, yet there exists no substantial diagnostic tool(s) for recognizing defects at these early stages. Cardiac morphogensis occurs throughout the pre-innervated period of embryonic development. It is speculated that the flow of blood during the early embryonic stages plays an important role in the development of the cardiovascular system. Blood flow is a possible mechanism for communication between the heart and vasculature, contributing to cardiac development. The objective of …

A Petri Net Design, Simulation, And Verification Tool, Richard Brink

Theses

Increasing desire for thorough simulation and analysis of engineered products is quickly replacing the prototype and test design model. Petri nets are important instruments for modeling concurrent, distributed, asynchronous, parallel, deterministic, and non-deterministic systems. This tool provides designers with the ability to easily specify a Petri net design with an easy to use user interface, then simulate and analyze the Petri net to determine essential design properties using the reachability tree technique. The tool will construct a reachability tree, then analyze the tree for properties of safeness, boundedness, liveness, and conservativeness.

Only In The Earth, Miran Lee

Theses

In only a few short years, multimedia has become powerful and accepted enough to begin taking its rightful place in the changing the way we communicate. Communication in the '90s must accomplish two fundamental tasks: satiating the demanding aesthetic tastes and expectations of today's sophisticated viewing audiences, and navigating the vast amount of knowledge, facts, and statistics that comprise the "Information Age." Multimedia allows us to use the best combination of media to present com pelling information suited to specific situations. It allows user-control over how and when that information is accessed. "Only In The Earth" is the ultimate multimedia …

Synthetic Simulation And Modeling Of Image Intensified Ccds (Iiccd), Emmett Ientilucci

Theses

Image intensifying cameras have been found to be extremely useful in low-light-level (LLL) scenarios including military night-vision and civilian rescue operations. These sensors utilize the available visible region photons and an amplification process to produce high-contrast imagery. Today's image intensifiers are usually attached to a CCD and incorporate a microchannel plate (MCP) for amplification purposes. These devices are commonly referred to as image intensified CCDs (IICCD). To date, there has not been much work in the area of still-frame, low-light-level simulations with radiometric accuracy in mind. Most work has been geared toward real-time simulations where the emphasis is on situational …

Application Of Tube Settlers In Secondary Wastewater Treatment, Abdulsalam Mohamed Saleh Kamalpoor

Theses

Secondary sedimentation is one of the most commonly used unit operations in wastewater treatment plants. It is customary designed to achieve solids separation from biologically treated effluent through clarification of biological solids and thickening of sludge. As treatment plants receive increasingly high wastewater flow, conventional sedimentation tanks suffer from overloading problems which result in poor performance. Inclined plate settlers, a form of tube settlers, may have good potential in upgrading sedimentation tanks. This study was conducted to examine the possibility of applying inclined plate settlers in secondary sedimentation in order to upgrade conventional rectangular sedimentation tanks and improve their performance. …

Environmental Study Indoor And Outdoor Of The Abu Dhabi Compost Plant, Jaber Eidha S. Aljabri

Theses

The transformation of municipal solid waste into compost is of double interest: on the one hand, it helps to avoid the deficiencies of natural manure, and on the other it eliminates this major polluting agent which is increasing progressively as a consequence of rising populations.

Domestic waste produced per person per annum amounts to 730 kg in Abu Dhabi city. Based on a population in 1992 of 574,745, this gives a current daily refuse collection that amounts to 1120 tons. Refuse is reported to contain a high proportion of organic materials and therefore to be suitable for recycling to produce …

Hepatic Cytochromes P450 Enzyme Activities Of Uae Coastal Rabbit Safi Fish Siganus Canaliculatus, Amna Mana Al-Otaiba

Theses

The cytochrome P450 dependent metabolism of benzo(a)pyrene and other xenobiotics has been investigated in liver microsomes prepared from a local marine Safi fish Siganus canaliculatus caught from the Arabian Gulf of United Arab Emirates. The Safi fish was found to have a well developed liver microsomal monooxygenase system consisting of cytochrome P450, cytochrome b5 and NADPH-cytochrome c reductase. The fish microsomal enzyme system was able to metabolise benzo(a)pyrene, 7-ethoxycoumarin and 7- ethoxyresorufin. Male fish were found to exhibit a higher monooxygenase activity than female fish. Treatment of fish with β-naphthoflavone was found to induce (2-4 fold) the activities of aryl …

Measurement Of The Electroencephalogram (Eeg) Coherence, Atmospheric Noise, And Schumann Resonances In Group Meditation, Douglas A. Newandee

Theses

Electrical activity in the human body was investigated using EEG and ECG measurements while subjects remained with eyes open, eyes closed and in a meditation state. During these measurements, additional antennas were attached to the equipment to record atmospheric noise and signal activity simultaneously. The obtained data was analyzed and various observations were made. Processed data based on antenna signals clearly showed the presence of man-made signals, having narrow spectral widths that could be treated as atmospheric noise in the frequency range up to 50 Hz. In addition, signals clustered around 7.8, 14.1, 20.3, 26.4, and 32.5 Hz were observed …

Stratospheric Ozone Layer Depletion : A Computer Aided Case Study, James M. Lipuma

Theses

In industries today, there is a desire to stop pollution before it starts, through the process of pollution prevention. Unfortunately, many university level students are not exposed to the thinking process involved in environmental problem solving early enough in their academic career, if they are exposed to it at all. The goal of this thesis is to develop and to evaluate an interdisciplinary case-study about the depletion of the stratospheric ozone layer by chlorofluorocarbons (CFCs). This case-study will be used to teach first year chemistry students about environmental problem solving. The case study was assembled from existing literature according to …

Advanced Characterization And Leaching Behavior Of Hexavalent And Trivalent Chromium From Waste Material, Erik Moerman

Theses

In this thesis we employed advanced characterization techniques such as XRF, XRD, XPS, SEM, and EDS to provide detailed information about the chromium waste _ specifically chromium valence states (Cr(VI) and Cr(III)), and their chemical association with other phases in the waste matrix.

The removal of Cr(VI) was accomplished by leaching with aqueous solutions containing inorganic anions such as Cl^-, SO₄^2-, PO₄^3- and others. Cr(VI) can be released from the waste by a combination of desorption and ion exchange processes. The efficiency and kinetics of displacing CrO₄^2- from the waste by …

A Mathematical Model Of Cardiovascular System With Feedback Control, Jiayu Gu

Theses

A mathematical model of human cardiovascular system is presented in this study. The closed-loop model is composed of twenty compartments which includes the left and right ventricles, and the systemic and pulmonary circulations. Two physiologic feedback control mechanisms, autoregulation of blood flow and baroreceptor reflex regulation of arterial pressure, are incorporated in the model. Autoregulation acts by changing local resistance to blood flow through metabolic and myogenic mechanisms, thereby insuring a match between oxygen supply and demand for any tissue or organ. Baroreceptors act through neural pathways to alter heart rate, contractility and peripheral resistance in order to return sudden …

Bringing Ideas Back To The Evolution Of Design, Ayca Tuzmen

Theses

This thesis is an exploration into the evolution of design. It attempts to develop an awareness of the effectiveness of what we do as designers and users to improve design. To achieve this purpose, it elaborates on some of the implications of paradigms which have emerged in design evolution. It presents some of the evolutionary theories and their analogies. These theories and analogies develop a view of design evolution - a conception of design as a process which moves from a lower to a higher state. With this conception, concern is directed at the identification of past and current design …

A New Concept In Artificial Ligament And Tendons Modeling : Finite Element Analysis, Miroslaw Sokol

Theses

Reconstruction of the Anterior Cruciate Ligament (ACL) has been a major focus in sports medicine for over twenty years. Severe or unrepairable damage of the ACL due to sport injury is a major problem faced by orthopedic surgeons and engineers. To successfully replace or reconstruct an injured ACL, the mechanical properties as well as the dimensional limitation of the material used must be similar to the biological ligaments. Although excessive literature describes experimental investigation on the mechanical property and clinical application of the ligament material, there is no analytical study that describes strains, stresses, and endurance in the bone/ligament/bone complex. …

Usability Of Hypertext : Factors Affecting The Construction Of Meaning, Kathryn L. King

Theses

One type of hypertext application, information retrieval, has become increasingly popular and accessible due to the explosion of activity occurring on the World Wide Web. These hypertext documents are referred to as web sites. Readers can now access a multitude of web sites and retrieve a wide variety of information.

The uniqueness of a hypertext document centers around the concept that text is broken into an array of non-sequential text chunks, or nodes, which are connected through links. The hypertext reading can be considered an interactive experience requiring the reader to effectively navigate the document. The potentially complex link and …

Graphical Visualization Of Control System Performance, Jeffrey Marx

Theses

University courses on control system design have traditionally relied on the root locus approach to predict transient system output. However, the increasing speed of personal computers has made it practical to design control systems by simulating their time and frequency responses. This thesis presents an interactive Matlab program for control system analysis and design. The system is defined in Simulink with a user-specified gain parameter of variable magnitude. The gain parameter is automatically varied by the program within user-specified bounds. Several surface and performance plots are produced which describe system time-domain and frequency-domain performance. The system root locus is also …
