Analyzing software repository data to synthesize and visualize relationships between development artifacts

Unknown Date (has links)
As computing technology continues to advance, it has become increasingly difficult to find businesses that do not rely, at least in part, upon the collection and analysis of data for the purpose of project management and process improvement. The cost of software tends to increase over time due to its complexity and the cost of employing humans to develop, maintain, and evolve it. To help control the costs, organizations often seek to improve the process by which software systems are developed and evolved. Improvements can be realized by discovering previously unknown or hidden relationships between the artifacts generated as a result of developing a software system. The objective of the work described in this thesis is to provide a visualization tool that helps managers and engineers better plan for future projects by discovering new knowledge gained by synthesizing and visualizing data mined from software repository records from previous projects. / by James J.

Augmented reality methods and algorithms for hearing augmentation

Unknown Date (has links)
While new technologies are often used to facilitate regular people's lives, they often fail to see their potential in helping disabled people. Augmented reality, one of the newest state-of-the-art technologies, offers users the opportunity to add virtual information to their real world surroundings in real time. It also has the potential to not only augment the sense of sight, but also other senses such as hearing. Augmented reality could be used to offer the opportunity to complement users' missing sense. In this thesis, we study augmented reality technologies, systems and applications, and suggest the future of AR applications. We explain how to integrate augmented reality into iOS applications and propose an augmented reality application for hearing augmentation using an iPad2. We believe mobile devices are the best platform for augmented reality as they are widespread and their computational power is rapidly growing to be able to handle true AR applications. / by Julie Carmigniani. / Thesis (M.S.C.S.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

Implementation of an improved embedded SQL for Java

Unknown Date (has links)
The Java Devlopment Environment defines SQLJ as a standard way of embedding the relational database language SQL in the object-oriented programming language Java. Oracle Corporation provides an extension of SQLJ that supports dynamic SQL constructs for the processing of SQL commands that are not completely known at compile time. Unfortunately, these constructs are not sufficient to handle all dynamic situations, so that the programmer has to depend on other SQL embeddings, such as JDBC, in addition to Oracle's SQLJ. In this thesis we implement several extensions to Oracle's SQLJ so that all dynamic situations can be programmed in SQLJ, without resorting to other SQL embeddings. We also add a sub-query based for loop facility, similar to the one provided in Oracle's database programming language PL/SQL, as an improvement over the iterator constructs that SQLJ provides. This thesis discusses the design, development and implementation of these SQLJ extensions, and provided applications that show the utility of these extensions in terms of clarity and power. / by Louis M.

A service-oriented component-based framework for enterprise systems development

He, Fangzhou January 2011 (has links)
Thesis (MTech. degree in Software Development.)--Tshwane University of Technology, 2011 / With regards to extending component-based and service-oriented system development approaches and solving current problems related to enterprise systems, this study will explore the requirements and challenges of current enterprise systems, and define an SCSD (Service-oriented Component-based System Development) framework which would provide all-round service-oriented component-based support for a complex application environment. The purpose of this study is to create a novel SCSD framework which combines the features of both component-based and service-oriented paradigms, as well as avoid the weaknesses of the existing service and component combination approaches. The SCSD framework combines the re-usability of the component-based paradigm and the flexibility of the service-oriented paradigm. Reusable SCSD-based components and services can reduce costs, shorten development time, and improve service quality when implemented effectively. The SCSD framework offers an alternative to older system development approaches, while it also provides a new solution in order to establish relationships between services and components for current enterprise systems.

A model of mobile phone voting system for South Africa.

Mpekoa, Noluntu. January 2013 (has links)
M. Tech. Information Technology / Voting is a widely spread and democratic way of making decisions. For centuries, South Africa has been using the popular paper-based voting system though it does not provide the desirable blend of accessibility and efficiency. Missing ballot papers, invalid votes and miscount are some of the challenges that come with the paper-based voting system. Time is precious to everyone and correct information is even more precious in the fast-paced information technology era. Merging all these together we look in for easier, effective, efficient and time managing way of casting a vote. Mobile phones facilitate communication and rapid access to information and their diffusion has reached a larger proportion of the population in a short period of time. In this thesis, we propose designing and developing a mobile phone voting system, which allows users to vote spontaneous and timeous, using existing mobile phone networks and technologies via their mobile phones.

Um modelo semântico para engenharia de aplicação de linhas de produto de software para sistemas tutores inteligentes / A semantic model for application engineering of software product lines intelligent tutoring systems

Ataíde, Walker Araújo 04 August 2015 (has links)
Intelligent Tutoring Systems (ITSs) are softwares that aims to represent human behavior inherent in the teaching process in any particular field in order to support the activities of teachers and offer a adapted teaching to students. ITSs have great potential both in the classroom teaching as the distance, however, its construction is a complex and expensive task that requires the presence of specialized professionals in computing and system domain being compounded when you need to build ITSs large-scale and adapted to each area. In this sense, the approach Software Product Lines (SPL) allows to build large-scale ITS. Complementarily, ontologies can be used to allow such a construction is automatically adaptable to different domains. However, in the application engineering phase of the SPL, when ITS are instantiated, is required manipulation of ontologies and different software artifacts, demanding the presence of professionals with expertise in ontology and software engineering, making it difficult the accomplishment of this task by authors / designers. Given the above, we propose an ontology-based model to automate the SPL application engineering for intelligent tutoring systems. Specifically, it is intended to automate the processes of customization, instantiation and deployment of an ITS of a SPL, making the manipulation of ontologies and software artifacts transparent to the user. The proposed model uses ontologies to represent the features and constraints of a generic SPL, the specific features for ITSs, the decisions of the author in terms of which features will be part of the ITS to be generated and the information of the student. The SPL application engineering process is performed by components that lead author by the steps of authentication in the system, selection of the SPL to be instantiated, customization/configuration of the features of ITS, validation, generation and deployment of ITS on a Web server. In order to validate the proposed model has been built a tool that automates the generation of products in a SPL. This tool was used on a case study involving the application engineering of an ITS from a SPL. The obtained results showed to be adequate singled out as major contributions, the design and development of a semantic model for the SPL application engineering for ITSs, this model guides the author through the process making transparent the use of ontologies and SPL, helps reduce complexity and effort (i.e., workload) in the construction of ITSs from semantic SPL, reduces the skills required to instantiate ITSs what can enable more people to perform this task and allows properly validate the configuration of the features of the ITS to be instantiated, allowing only products without misconfigurations can be generated. / Sistemas Tutores Inteligentes (STIs) são softwares que buscam representar o comportamento humano inerente ao processo de ensino em algum domínio específico com o objetivo de dar suporte às atividades de professores e oferecer um ensino adaptado aos estudantes. Os STIs têm grande potencialidade tanto no ensino presencial quanto a distância, entretanto, sua construção é uma tarefa complexa e dispendiosa que demanda a presença de profissionais especializados em computação e domínio do sistema sendo agravado quando se necessita construir STIs em larga escala e adaptados a cada domínio. Nesse sentido, a abordagem de Linhas de Produto de Software (LPS) possibilita construir STIs em larga escala. De forma complementar, ontologias podem ser utilizadas para permitir que tal construção seja automaticamente adaptável para diferentes domínios. Porém, na fase de engenharia da aplicação da LPS, momento em que os STIs são instanciados, faz-se necessária a manipulação de ontologias e artefatos de software distintos, demandando a presença de profissionais com conhecimentos em ontologia e engenharia de software, o que dificulta a realização dessa tarefa por autores/projetistas. Com base no exposto propõe-se neste trabalho um modelo baseado em ontologia para automatizar a engenharia de aplicação de LPS para sistemas tutores inteligentes. De maneira específica pretende-se automatizar o processo de customização, instanciação e implantação de STIs de uma LPS, tornando transparente ao usuário a manipulação de ontologias e artefatos de software. O modelo proposto utiliza ontologias para representar as funcionalidades e restrições de uma LPS genérica, as funcionalidades específicas para STIs, as decisões do autor em termos de quais funcionalidades farão parte do STI a ser gerado e as informações do aluno. O processo de engenharia de aplicação da LPS é realizado por componentes que conduzem o autor pelas etapas de autenticação no sistema, seleção da LPS a ser instanciada, customização/configuração das funcionalidades do STI, validação, geração e implantação de um STI em um servidor Web. Para validar o modelo proposto foi construída uma ferramenta que automatiza a geração de produtos em uma LPS. Tal ferramenta foi utilizada em um estudo de caso abrangendo a engenharia de aplicação de um STI a partir de uma LPS. Os resultados obtidos mostram-se adequados apontando como principais contribuições a concepção e desenvolvimento de um modelo semântico para a engenharia de aplicação de LPS para STIs, este modelo guia o autor pelo processo tornando transparente o uso de ontologias e LPS, auxilia na redução da complexidade e do esforço empregado (i.e., carga de trabalho) na construção de STIs a partir de LPS semântica, reduz as qualificações exigidas para instanciar STIs ao qual pode possibilitar que mais pessoas realizem essa tarefa e permite validar corretamente a configuração das funcionalidades do STI a ser instanciado de forma que apenas produtos sem erros de configuração sejam gerados.

FeatureIT : a platform for collaborative software development

Siller, Gavin George 02 1900 (has links)
The development of enterprise software is a complex activity that requires a diverse set of stakeholders to communicate and coordinate in order to achieve a successful outcome. In this dissertation I introduce a high-level physical architecture for a platform titled FeatureIT that has the goal of supporting the collaboration between stakeholders throughout the entire Software Development Life Cycle (SDLC). FeatureIT is the result of unifying the theoretical foundations of the multi-disciplinary field of Computer Supported Cooperative Work (CSCW) with the paradigm and associated technologies of Web 2.0. The architecture was borne out a study of literature in the fields of CSCW, Web 2.0 and software engineering, which facilitated the identification of functional and non-functional requirements necessary for the platform. The design science research methodology was employed to construct this architecture iteratively to satisfy the requirements while validating its efficacy against a comprehensive set of scenarios that typically occur in the SDLC. / Computing / M.

Process control and configuration of a reconfigurable production system using a multi-agent software system

Janse van Rensburg, Jean January 2011 (has links)
Thesis (M. Tech. (Information Technology)) -- Central University of technology, Free State, 2011 / Traditional designs for component-handling platforms are rigidly linked to the product being produced. Control and monitoring methods for these platforms consist of various proprietary hardware controllers containing the control logic for the production process. Should the configuration of the component handling platform change, the controllers need to be taken offline and reprogrammed to take the changes into account. The current thinking in component-handling system design is the notion of re-configurability. Reconfigurability means that with minimum or no downtime the system can be adapted to produce another product type or overcome a device failure. The re-configurable component handling platform is built-up from groups of independent devices. These groups or cells are each responsible for some aspect of the overall production process. By moving or swopping different versions of these cells within the component-handling platform, re-configurability is achieved. Such a dynamic system requires a flexible communications platform and high-level software control architecture to accommodate the reconfigurable nature of the system. This work represents the design and testing of the core of a re-configurable production control software platform. Multiple software components work together to control and monitor a re-configurable component handling platform. The design and implementation of a production database, production ontology, communications architecture and the core multi-agent control application linking all these components together is presented.
