The Public Administrationist As Civic Shaman: The Self-Reflective Integrator Of Policy Frames Of Reference And Social Character, Phillip A. Brown

Dissertations

This study discusses the discipline of Public Administration and the Public Administrationist in relation to policy frames of reference and social character. The relationship of policy frames of reference and social character is the basis for public trust As the American political system becomes more and more fragmented, public administrationists, sometimes by default, become the trustees for safeguarding the public trust.

The concept of policy frames of reference, as it evolves in this discussion, refers to the ability of the public administrationist to understand the interactions of changing issues impacting on the interactions of changing issues, or quantum thinking. Social …

The Discriminative Stimulus Properties Of Morphine And U-50,488h In A Three-Key Assay: A Mu And Kappa Opioid Discrimination In The Pigeon, Malath Makhay

Dissertations

Opiate drugs have been classified in two-choice assays according to their ability to produce generalization in animals to the prototypicix opiate, morphine, versus vehicle, or to the k opioid, U -50,488H versus vehicle injections (Picker & Dykstra, 1987). A three-choice discrimination procedure, in which subjects discriminate among morphine, U -50,488H , and vehicle injections, might afford a greater degree of precision in characterizing the subjective effects of opioids. The feasibility of such a procedure was demonstrated in the present study, in which five pigeons were trained to discriminate among injections of 5 .6 m g/kg morphinel 5 .6 m g/kg …

Effects Of D-Amphetamine On Free-Operant Response Acquisition With Immediate And Delayed Reinforcement, Mark G. Lesage

Dissertations

The present study examined in 8-hour sessions the effects of d-amphetamine (1.0, 5.6, and 10 mg/kg) on the acquisition of lever-press responding by rats exposed to procedures in which water delivery was delayed by 0, 8, or 16 seconds relative to the response that produced it. Although neither shaping nor autoshaping occurred, substantial levels of operative-lever responding developed whenever responses produced water. Rats that did not receive water and yoked-control rats that received response-independent water emitted relatively few responses.

The lowest dose (1.0 mg/kg) of d-amphetamine either had no effect on or enhanced rates of operative-lever pressing, whereas …

An Investigation Of The Relationship Between Homework Assignments In Counseling And Perceptions Of Specific Counselor Characteristics, George T. Starrett

In order to achieve this objective, an experimental nonlinear dynamic system is considered. The motivation for this comes from the desire to solve practical problems and to create a test-bed which can be used to test various control strategies. The nonlinear dynamic system considered here is an …

Investigation Of Dynamic Friction In Lubricated Surfaces, Hanuman Rachoor

Dissertations

The research reported in this dissertation is concerned with the development of friction models for lubricated contacts. A few analytical models have been developed to investigate the friction under dynamic velocity conditions. In this study, two different tribological situations such as conformal and non-conformal contacts have been chosen. Friction modeling covers boundary, mixed and full fluid film friction regions. A new theory based on the elastic properties of the surface materials, and fluid film properties of the lubricant at the contact has been developed to determine the dynamic friction in boundary, mixed and full hydrodynamic lubrication regions. In the full …

Adaptive Space-Time Processing For Wireless Communications, Xiao Cheng Bernstein

Dissertations

Adaptive space-time processing techniques have been found to increase the capacity of two major, multiple-access wireless communication systems: Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA).

In an IS-54 TDMA system, the frequency re-use factor has to be set to 7 so that cells with the same spectrum are separated far enough to meet a required carrier-to-interference ratio (CIR). Space processing uses multiple antennas which, in turn, provide alternative signal paths in order to cancel interferences and combat multipath fading. We have proposed the eigencanceler method and have reviewed the theoretical optimum combining and the feasible direct …

Identifying And Exploiting Concurrency In Object-Based Real-Time Systems, Guohui Yu

Dissertations

The use of object-based mechanisms, i.e., abstract data types (ADTs), for constructing software systems can help to decrease development costs, increase understandability and increase maintainability. However, execution efficiency may be sacrificed due to the large number of procedure calls, and due to contention for shared ADTs in concurrent systems. Such inefficiencies are a concern in real-time applications that have stringent timing requirements. To address these issues, the potentially inefficient procedure calls are turned into a source of concurrency via asynchronous procedure calls (ARPCs), and contention for shared ADTS is reduced via ADT cloning. A framework for concurrency analysis in object-based …

On Optimal Design And Applications Of Linear Transforms, Mehmet V. Tazebay

Dissertations

Linear transforms are encountered in many fields of applied science and engineering. In the past, conventional block transforms provided acceptable answers to different practical problems. But now, under increasing competitive pressures, with the growing reservoir of theory and a corresponding development of computing facilities, a real demand has been created for methods that systematically improve performance. As a result the past two decades have seen the explosive growth of a class of linear transform theory known as multiresolution signal decomposition. The goal of this work is to design and apply these advanced signal processing techniques to several different problems.

The …

On The Optimization Problems In Multiaccess Communication Systems, Gangsheng Wang

Dissertations

In a communication system, the bandwidth is often a primary resource. In order to support concurrent access by numerous users in a network, this finite and expensive resource must be shared among many independent contending users. Multi-access protocols control this access of the resource among users to achieve its efficient utilization, satisfy connectivity requirements and resolve any conflict among the contending users. Many optimization problems arise in designing a multi-access protocol. Among these, there is a class of optimization problems known as NP-complete, and no polynomial algorithm can possibly solve them. Conventional methods may not be efficient arid often produce …

Anaerobic Digestion And Acid Hydrolysis Of Nitrocellulose, Fong-Jung Tai

Dissertations

In this investigation, studies were conducted to evaluate the biodegradation of nitrocellulose in anaerobic batch reactors with and without the supplemental carbon inducers, such as cellulose, cellobiose, and lactose. Results from the anaerobic study show that degradation of nitrocellulose alone is difficult and that nitrocellulose degradative enzymes could be induced by the three inducers tested. As high as 48.91% conversion could be obtained at Cellulose/Nitrocellulose ratio of 1 to I. Studies also indicated that type 20 and 50 celluloses would be more effective and optimum pH was about 6.4 in biodegradation of nitrocellulose. Three testing systems, namely, single-stage, two-stage, and …

An Investigation Of The Mechanism Of Advanced Oxidation Processes (Aop) Involving Free Radicals And Charged Species., Yaw-Kuen Lin

Dissertations

Hydrogen peroxide is a key component in Advanced Oxidation Processes (AOP). Its decomposition at different pH conditions has been studied and some interesting results were observed. When the pH value of hydrogen peroxide solution is less than 9, its rate of decomposition is independent of pH. On the other hand, in the pH range of 9-12.6, its rate of decomposition increases as pH increases, and goes through a maximum value then suddenly decreases with respect to pH. A reaction kinetic model with three rate constants in the form of beta probability function was used to describe the experimental data of …
