Distributed Management Of Heterogeneous Networks Using Hypermedia Data Repositories, James M. Anderson
Electronic Theses and Dissertations 1990 - 1999
Current management architectures address portions of the problem of managing high speed distributed networks; however, they do not provide a scalable end-to-end solution that can be applied to both large LAN and WAN high speed distributed networks. A new management architecture, "Web Integrated Network for Distributed Management Including Logic" (WINDMIL), is proposed to address the challenges of managing complex heterogeneous networks. The three primary components of the system are the Network Management Server (NMS), the Network Element Web Server (NEWS), and the Operator's Logic and Processing Platform (OLAPP). The NMS stores the management functions used by both the NEWS and …

Electronic Theses and Dissertations 1990 - 1999
In this dissertation, new semi-analytical expressions for the diversity bit error rate performance of asynchronous direct sequence-code division multiple access (DS-CDMA) systems in multipath fading channels are derived. Also, the PN acquisition time of a DS system with offset frequency periods greater than the code period in a AWGN channel is measured via laboratory experiments. In Part I we consider DS-CDMA systems operating in a cellular environment with multipath reception. Multipath propagation is exploited through the use of RAKE receivers. Coherent, differentially coherent and noncoherent binary demodulation schemes are considered. The multiple access interference is modeled as AWGN, conditioned on …
Domestic Sybil: Feminist Concerns In P. L. Travers's "Mary Poppins" And "Mary Poppins Comes Back", Donna M. Revtai
Domestic Sybil: Feminist Concerns In P. L. Travers's "Mary Poppins" And "Mary Poppins Comes Back", Donna M. Revtai
Electronic Theses and Dissertations 1990 - 1999
Certain elements in P. L. Travers's Mary Poppins (1934) and Mary Poppins Comes Back (1935) depict concerns that feminist critics deem important, such as mother figures, females as artists, women who exert power or lack it, female self-concepts, matrilineal connections and mother/child relationships. Travers sometimes treats these subjects ambiguously or ambivalently, but her attention to them indicates a riveting interest at the time. Her creative process whereby she projected childhood fantasies onto her ideal nanny, Mary Poppins, with whom she identified herself and others, relates to a feminine psychology. Travers's cyclic and web-like plots may link her to feminist aesthetics …

Duration And The Prices Of Common Stocks, Yehuda A. Konnan
Duration And The Prices Of Common Stocks, Yehuda A. Konnan
Electronic Theses and Dissertations 1990 - 1999
In finance, the term 'duration' means the effective length of a financial obligation which is discharged in installments. This concept has a number of applications in finance like calculating the change in the price of bonds due to the change in interest rates, immunizing the value of bonds, etc. Common stocks are also financial obligations and are considered to have durations. For bonds and similar strong contractual obligations, duration and its applications are clear cut and are used widely. For common stocks duration evaluation is difficult and its practical applications hardly exist. Moreover, there are no publications of numerical results …
Echoes Of Wordsworth And Coleridge Resound In "The Accidental Tourist", Susan Clare Finger
Echoes Of Wordsworth And Coleridge Resound In "The Accidental Tourist", Susan Clare Finger
Electronic Theses and Dissertations 1990 - 1999
Anne Tyler, who lived a "Romantic" childhood in mountain-terrained communes of North Carolina, borrowed ideas from Wordsworth and Coleridge for her 1985 novel The Accidental Tourist. Reflections of these Romantic poets are seen primarily in images but are also seen in Tyler's simple writing style. Macon Leary, the protagonist of the novel, is a wandering writer who loves the English language, but struggles to communicate his feelings verbally, a reflection of Romantic ideology. Other motifs include home as a place abandoned as well as a refuge for the mind and body; the destructive and renewing powers of the city; physical …

Differential Power, Moral Hazard, And Preferred Monitoring Mode In Marketing Channels, Prakasam R. Devasagayam
Differential Power, Moral Hazard, And Preferred Monitoring Mode In Marketing Channels, Prakasam R. Devasagayam
Electronic Theses and Dissertations 1990 - 1999
This research examines the impact of differential power on the choice of monitoring mode in interorganizational relationships in marketing channels. Interorganizational relationships in channels of distribution can be considered agency relationships because they involve delegation of value-adding tasks by one participant (principal) to another participant (agent). Moral Hazard or the likelihood of an agent pursuing individual goals at the expense of mutually satisfying common goals may result in suboptimal outcomes and necessitates monitoring by the principal. Monitoring involves procuring information on the effort expended by the agent (behavior-based monitoring) and the resultant outcomes of such efforts (outcome-based monitoring). A comparison …

Diversity Techniques In Direct Sequence Code Division Multiple Access Communication Systems, Okechukwu Clark Ugweje
Electronic Theses and Dissertations 1990 - 1999
This dissertation investigates the performance of different space diversity combining techniques for the wireless mobile communication systems employing Direct Sequence-Code Division Multiple Access (DS-CDMA). It covers two research topics, all falling under the umbrella of diversity combining techniques. The first part deals with diversity reception of wideband DS-CDMA signals in which the diversity branches experience some correlation. This analysis is performed without the usual assumption that diversity branches are independent and hence uncorrelated. In this case, the analysis is limited to the conventional diversity techniques such as maximal ratio combining, equal gain combining and selection diversity. In particular, the effect …

Electrochemical Double-Layer Capacitors Utilizing Low Surface Area Graphite Fibers, David Isaiah Zawacki
Electronic Theses and Dissertations 1990 - 1999
Electrochemical double-layer capacitors were constructed using low surface area carbon fibers that are commercially available. The fibers were made from polyacrylonitrile (PAN) and pitch and vary from low (LC = 14A, d002 = 3.54A) to high (LC = 169A, d002 = 3.40A) crystallinity. High energy densities (up to 7.83 Wh/kg) were obtained by electrochemically intercalating HSO4- ions between the graphene planes of the carbon fibers. The intercalation process was strongly influenced by the crystallinity of the carbon fiber and by the precursors from which the fiber was manufactured. All the pitch fibers had a higher structural order and a higher …
Embrittlement Susceptibility Of Corroded Pre-Stressing Steel In Concrete During Cathodic Polarization, Arnaud. Poeydomenge
Embrittlement Susceptibility Of Corroded Pre-Stressing Steel In Concrete During Cathodic Polarization, Arnaud. Poeydomenge
Electronic Theses and Dissertations 1990 - 1999
Experiments and analyses were performed to better define the limits of concern regarding hydrogen embrittlement in association with application of cathodic protection to prestressed concrete. To accomplish this, prestressed concrete specimens were locally corroded to different levels by anodic polarization and then polarized to -1.30 V SCE. A procedure of examination was developed using strain gauges to determine the level of prestrain. Relatively few brittle failures of wires resulted due, at least in part, to a relatively low prestrain of the pretensioned tendons. A model was developed which, coupled with data from parallel research, permitted definition of the minimum cross …
Empirical Analysis Of The Convergence Hypothesis Across Countries: New Evidence, Blake Donald Butzin
Empirical Analysis Of The Convergence Hypothesis Across Countries: New Evidence, Blake Donald Butzin
Electronic Theses and Dissertations 1990 - 1999
The Solow growth model examines the effects of saving, population and technological advances on the growth of an economy. Long-run economic growth is explained by the exogenous variable, technology. In this model lower income countries will experience higher rates of economic growth, which will lead to convergence in the standards of living between low-income and high-income countries. Additional theories including the augmented Solow model, which tests for conditional convergence and endogenous growth theories have been developed recently. An empirical inquiry of the convergence hypothesis has been conducted using a variety samples based on income classifications and geographical locations.

Employment Of Modern Analytical Methods For Adsorption Studies And Pharmaceutical Analysis, Wendy Marie Foss
Employment Of Modern Analytical Methods For Adsorption Studies And Pharmaceutical Analysis, Wendy Marie Foss
Electronic Theses and Dissertations 1990 - 1999
Ultraviolet spectrophotometry was employed to investigate the adsorption of phenylphosphonic acid onto the surface of alumina from aqueous solution. It was found that an initial chemisorption occurred with monolayer coverage, reaching a maximum at a solution pH of 3.0. The results were interpreted as indicating that this and related adsorptions are controlled by ligand exchange processes involving electrostatic attraction between oppositely-charged species. In a separate project, high performance liquid chromatography was employed for the quantitative analysis of aminophylline in commercial thigh cream formulations. The analysis required derivatization of the compound by dansylation under carefully-controlled conditions. This enhanced its detection and …
