Extending Use Cases And Interaction Diagrams To Develop Distributed System Architecture Requirements, John C. Hawkins Jan 1997

Extending Use Cases And Interaction Diagrams To Develop Distributed System Architecture Requirements, John C. Hawkins

Electronic Theses and Dissertations 1990 - 1999

Current object-oriented development methodologies do not introduce distributed system architectural aspects early enough in the system development cycle. A development partitioning scheme that includes the system level, in addition to the problem and application levels, will encourage analysis that includes elicitation of non-functional system requirements. These requirements include response time with respect to system communication load, fault tolerance, safety, security, and real-time deadlines, among others. They can be documented with an extended form of Jacobson's use cases. Where use cases describe how a system will work from a user's point of view, extended use cases add the capability to describe …


Florida Local Government Compliance With Transportation Concurrency, Raymond A. Liberti Jan 1997

Florida Local Government Compliance With Transportation Concurrency, Raymond A. Liberti

Electronic Theses and Dissertations 1990 - 1999

Growth management grew as a concept and policy objective in the 1970s and 1980s. The interrelationships of the state and local governments changed when Florida developed growth policy and local government implemented the policy. Nine mandatory elements to be included in a local comprehensive plan and seven mandatory concurrency elements of the 1985 Florida Growth Management Act were expensive elements for local government to implement. As a result, the issue of funding the impacts of growth drove the growth management agenda, leaving the question of compliance. The question is: Did Florida local government comply with the transportation concurrency element of …


Generating Formal Models From Uml Class Diagrams, Malcolm Keki Shroff Jan 1997

Generating Formal Models From Uml Class Diagrams, Malcolm Keki Shroff

Electronic Theses and Dissertations 1990 - 1999

The rich structuring mechanisms, and abstract modeling constructs available in most graphical object-oriented modeling methods (OOMs) facilitate the creation of abstract, visually-appealing, highly-structured graphical models. On the other hand, lack of formal semantics for the modeling notation can severely limit the utility of OOMs. Formal specification techniques (FSTs) support the creation of precise and analyzable specifications, but they can be tedious to create and difficult to read, especially by system developers not trained in formal methods. The complementary strengths of OOMs and FSTs suggest that their integration can result in techniques that can be used to create precise and analyzable …


Simultaneous Pressure-Temperature Measurements In A Heat Pipe, Madhavan. Jayanth Jan 1997

Simultaneous Pressure-Temperature Measurements In A Heat Pipe, Madhavan. Jayanth

Electronic Theses and Dissertations 1990 - 1999

When a heat pipe operates with a large temperature difference between the two ends, the vapor liquid combination is not in thermodynamic equilibrium. The experiments showed that the vapor liquid mixture is in a higher state of saturation at the condenser as compared to other sections of the pipe. Correlations were obtained that relate the coefficient of thermal coupling alpha to the evaporator flux and mass of NCG (non-condensable gas). As mass of NCG is increased in the heat pipe, the thermal coupling coefficient alpha decreases. The evaporator heat flux is directly proportional to alpha. The coefficient alpha is related …


Software Reliability Engineering: An Evolutionary Neural Network Approach, Robert. Hochman Jan 1997

Software Reliability Engineering: An Evolutionary Neural Network Approach, Robert. Hochman

Electronic Theses and Dissertations 1990 - 1999

This thesis presents the results of an empirical investigation of the applicability of genetic algorithms to a real-world problem in software reliability--the fault-prone module identification problem. The solution developed is an effective hybrid of genetic algorithms and neural networks. This approach (ENNs) was found to be superior, in terms of time, effort, and confidence in the optimality of results, to the common practice of searching manually for the best-performing net. Comparisons were made to discriminant analysis. On fault-prone, not-fault-prone, and overall classification, the lower error proportions for ENNs were found to be statistically significant. The robustness of ENNs follows from …


Sparse Volume Array For Imaging Ocean Ambient Noise In The Near-Shore Region, Marc P. Olivieri Jan 1997

Sparse Volume Array For Imaging Ocean Ambient Noise In The Near-Shore Region, Marc P. Olivieri

Electronic Theses and Dissertations 1990 - 1999

Ocean ambient noise has been studied extensively in the past, and several models have been developed to predict its level and to characterize it in different ocean environments. However, most of these studies have been motivated by the need to reduce the negative effect of the ambient noise on measurements. Recently, several studies have used the ambient noise to obtain information about the ocean floor and to achieve passive target detection. This dissertation describes the development of an Ambient Noise Sonar (ANS) which can be used to measure ambient noise directivity to obtain information about the environment. The system was …


Software Metrics Collection: Two New Research Tools, Sylviane G. Jordan Jan 1997

Software Metrics Collection: Two New Research Tools, Sylviane G. Jordan

Electronic Theses and Dissertations 1990 - 1999

Collecting software metrics manually could be a tedious, inaccurate, and subjective task. Two new tools were developed to automate this process in a rapid, accurate, and objective way. The first tool, the Metrics Analyzer, evaluates 19 metrics at the function level, from complete or partial systems written in C. The second tool, the Call Graph Generator, does not assess a metric directly, but generates a call graph based on a complete or partial system written in C. The call graph is used as an input to another tool (not considered here) that measures the coupling of a module, such as …


Statistical Modeling Of The Container Inventory Control In A Distribution Network, Weiming. Feng Jan 1997

Statistical Modeling Of The Container Inventory Control In A Distribution Network, Weiming. Feng

Electronic Theses and Dissertations 1990 - 1999

The study of the reusable container inventory control in a distribution network is crucial to the efficiency and cost effectiveness of the transportation systems. In order to minimize the total operation cost of such a transportation network system, all subsystems of the distribution network have to be optimized together as a whole system. In this study, we extended the inventory control concept and developed a multiple-inventory control model for the transportation network. We presented a systematic approach to address all those subsystems as interrelated systems. Mathematical models were developed for the transportation and container inventory control problems first. Then, the …

Hope And Despair For A New South Africa: The Limits Of Rights Discourse, Makau Wa Mutua Jan 1997

Hope And Despair For A New South Africa: The Limits Of Rights Discourse, Makau Wa Mutua

Journal Articles

This article is a critique of the struggle to end apartheid in South Africa. It explores the assumptions employed by the African National Congress and the international community to construct a post-apartheid society. It argues that the reliance on the law as the key medium for economic, social, and political change was insufficient to transform the legacy of apartheid. Instead, the piece contends that apartheid was privatized and its beneficiaries protected under the new dispensation. It makes the argument that the lot of the black majority is unlikely to be changed such gradualist approach to social change.

An Approach To Display Layout Of Dynamic Windows, Nihar Trivedi Jan 1997

An Approach To Display Layout Of Dynamic Windows, Nihar Trivedi

Theses: Doctorates and Masters

The development of windows based user interface has introduced a new dimension to the field of human computer interaction. Now a user is able to perform multiple tasks at a time, often switching from one task to another. However windows environment also imposes the burden of manual windows management on the user. Several studies have suggested that manual window management is an unproductive chore often resulting in clutter and confusion on the display screen. Therefore we need a automatic windows layout generator to free the user to perform other useful tasks. This thesis introduces SPORDAC {Shadow Propagation for Overlap Removal …


The Mathematical Modelling Of The Ross River Virus Transmission, Yoon-Hong Choi Jan 1997

The Mathematical Modelling Of The Ross River Virus Transmission, Yoon-Hong Choi

Theses: Doctorates and Masters

Ross River virus is one of the most severe communicable diseases in Australia. During the 1995/96 outbreak of Ross River virus in south-western Australia, over 1 ,300 human cases were reported. Since the symptoms of the disease are sometimes too weak to be diagnosed, it is important to determine the number of humans who actually contracted the virus during outbreaks. To do this, several mathematical models with different hypotheses are constructed and analysed mathematically. The threshold mathematical conditions of these models suggest that as well as the size of the vector mosquito population, the population size and length of viraemia …


Critical Competencies For Effective Teaching : Perceptions Of Home Economics Teachers, Esthery D. Kunkwenzu Jan 1997

Critical Competencies For Effective Teaching : Perceptions Of Home Economics Teachers, Esthery D. Kunkwenzu

Theses: Doctorates and Masters

Home economics is a multi-faceted, inter-disciplinary, integrated field of study drawing from a multitude of disciplines including sociology, psychology, anthropology, chemistry, physics, architecture and the arts (Henry, 1995). As a school subject, home economics in Malawi is taught at primary school, secondary school as well as at university level. This study explores home economics teachers' perceptions of competencies critical for teaching the subject. Data was collected from secondary school home economics teachers in Malawi. The study is a qualitative investigation of how experienced teachers describe effective teaching of the integrated home economics syllabus, and what they perceive as critical competencies …


Investigating Conditions For Higher Order Thinking In Telematics Environments, Catherine Mcloughlin Jan 1997

Investigating Conditions For Higher Order Thinking In Telematics Environments, Catherine Mcloughlin

Theses: Doctorates and Masters

Telematics, or audiographic conferencing, enables synchronous communication via telecommunications. A telephone link and computer communications allow students in distributed classrooms to participate in an extended, or virtual classroom. Telematics is widely used as an instructional medium for the delivery of curricula to students in rural and remote parts of Western Australia. Previous studies of learning meditated by this technology have shown limitations on the forms of interactivity, tasks and learner engagement. Students typically have been found to assume a passive role, often listening to a distant and invisible teacher, but not engaging in cognitively demanding tasks. The tendency for teachers …


Randomised Shuffle And Applied Misinformation: An Enhanced Model For Contact-Based Smart-Card Serial Data Transfer, Michael Collins Jan 1997

Randomised Shuffle And Applied Misinformation: An Enhanced Model For Contact-Based Smart-Card Serial Data Transfer, Michael Collins

Theses: Doctorates and Masters

Contact-based smart-cards, which comply to the International Standard IS0-7816, communicate with their associated read/write machines via a single bi-directional serial link. This link is easy to monitor with inexpensive equipment and resources, enabling captured data to be removed for later examination. In many contact-based smart-cards the logical abilities are provided by eight-bit microcontroller units (MCU) which are slow at performing effective cryptographic functions. Consequently, for expediency, much data may be transferred in plain-text across the vulnerable communications link, further easing an eavesdropper's task. Practitioners in military communications protect transmitted information by varying a link's carrier frequency in an apparently random …


The Relationship Between Enjoyment And Ongoing Participation In A Grade Dancesport, Diana Jonas-Dwyer Jan 1997

The Relationship Between Enjoyment And Ongoing Participation In A Grade Dancesport, Diana Jonas-Dwyer

Theses: Doctorates and Masters

To date no studies have considered enjoyment in Dancesport. Scanlan, Stein and Ravizza, (1989a, 1989b & 1991) have extensively studied enjoyment and recommended further studies be conducted in individual sports. Past research has tended to identity enjoyment as a one off momentary experience termed 'peak performance' (Cohn, 1991) and 'flow' (Csikszentmihalyi, 1975; Kimiecik & Stein, 1992). Many thousands of people participate in Dancesport, the competitive arm of ballroom dancing, both nationally and internationally. Determining the predictors of enjoyment for Dancesport could provide a base upon which to plan activity programs to increase lifelong participation and health. A qualitative approach was …


Fractal Relationships And Spatial Distribution Of Ore Body Modelling, D. J. Kentwell Jan 1997

Fractal Relationships And Spatial Distribution Of Ore Body Modelling, D. J. Kentwell

Theses: Doctorates and Masters

The nature of spatial distributions of geological variables such as ore grades is of primary concern when modelling ore bodies and mineral resources. The aim of any mineral resource evaluation process is to determine the location, extent, volume and average grade of that resource by a trade off between maximum confidence in the results and minimum sampling effort. The principal aim of almost every geostatistical modelling process is to predict the spatial variation of one or more geological variables in order to estimate values of those variables at locations that have not been sampled. From the spatial analysis of these …

The differential cross section dσ/dt for elastic ρ0 photoproduction, γp → ρ0ρ (ρ0 → π+π-), has been measured in ep interactions at HERA. The squared four-momentum exchanged at the proton vertex, t, has been determined directly by measuring the momentum of the scattered proton using the ZEUS Leading Proton Spectrometer (LPS), a large scale system of silicon micro-strip detectors operating close to the HERA proton beam. The LPS allows the measurement of the momentum of high energy protons scattered at small angles with accuracies of 0.4% for the longitudinal momentum and 5 MeV for the transverse momentum. Photoproduction of ρ0 …

The reaction γ p → J/ψ p has been studied in ep interactions using the ZEUS detector at HERA. The cross section for elastic J/ψ photoproduction has been measured as a function of the photon-proton centre of mass energy W in the range 40 < W < 140 GeV at a median photon virtuality Q2 of 5 × 10-5 GeV2. The photoproduction cross section, σγp→J/ψp, is observed to rise steeply with W. A fit to the data presented in this paper to determine the parameter δ in the form σγp→J/ψp α Wδ yields the value δ = 0.92±0.14±0.10. The differential cross section dσ/d|t| is presented over the range |t| < 1.0 GeV2 where t is the square of the four-momentum exchanged at the proton vertex. dσ/d|t| falls exponentially with a slope parameter of 4.6 ± 0.4-0.6+0.4 GeV-2. The measured decay angular distributions are consistent with s-channel helicity conservation. © Springer-Verlag 1997.

Diffractive dissociation of quasi-real photons at a photon-proton centre of mass energy of W ≈ 200 GeV is studied with the ZEUS detector at HERA. The process under consideration is γp → XN, where X is the diffractively dissociated photon system of mass MX and N is either a proton or a nucleonic system with mass MN < 2 GeV. The cross section for this process in the interval 3 < MX < 24 GeV relative to the total photoproduction cross section was measured to be σDpartial/σtot = 6.2 ± 0.2(stat) ± 1.4(syst)%. After extrapolating this result to the mass interval of mφ2 < MX2 < 0.05W2 and correcting it for proton dissociation, the fraction of the total cross section attributed to single diffractive photon dissociation, γp → Xp, is found to be σSD/σtot = 13.3 ± 0.5(stat) ± 3.6(syst)%. The mass spectrum of the dissociated photon system in the interval 8 < MX < 24 GeV can be described by the triple pomeron (IP IP IP) diagram with an effective pomeron intercept of αIP(0) = 1.12 ± 0.04(stat) ± 0.08(syst). The cross section for photon dissociation in the range 3 < MX < 8 GeV is significantly higher than that expected from the triple pomeron amplitude describing the region 8 < MX < 24 GeV. Assuming that this discrepancy is due to a pomeron-pomeron-reggeon (IP IP IR) term, its contribution to the diffractive cross section in the interval 3 < MX < 24 GeV is estimated to be fIP IP IR = 26 ± 3(stat) ± 12(syst)%. © Springer-Verlag 1997.
