Dissertations / Theses on the topic 'DSpace software'

Softwares now-a-days have become the life line of modern day organizations. Organizations cannot think of doing their tasks effectively and efficiently without softwares. The extremely competitive environment, zero deficiency and enhanced productivity has made it mandatory for the organizations to carefully choose the appropriate software after comprehensive needs assessment. Softwares simply their tasks and saves a lot of precious time which can be utilized in managing other important issues. Libraries also need softwares if they want to create a parallel digital library with features which we may not find in a traditional library. There are several open source softwares available to create a digital library. For this, firstly the library professionals should be aware of the advantages of open source software and should involve in their development. They should have basic knowledge about the selection, installation and maintenance. Open source software requires a greater degree of computing responsibility than commercial software. Digitization involves huge money to create and maintain and the OSS appears to be a means to reduce it. Among these, DSpace and Greenstone are becoming more popular in India and abroad. This paper deals with the comparison of these two popular OSS from various points of view. The comparative table may help the professionals who are planning to create a digital library.

Last year at the ECDL 2004 conference, we reported some initial progress and experiences developing DSpace as an open source community-driven project [8], particularly as seen from an institutional manager’s viewpoint. We also described some challenges and issues. This paper describes the progress in addressing some of those issues, and developments in the DSpace open source community. We go into detail about the processes and infrastructure we have developed around the DSpace code base, in the hope that this will be useful to other projects and organisations exploring the possibilities of becoming involved in or transitioning to open source development of digital library software. Some new challenges the DSpace community faces, particularly in the area of addressing required system architecture changes, are introduced. We also describe some exciting new possibilities that open source development brings to our community.

As more and more output from research institutions is born digital, a means for capturing and preserving the results of this investment is required. To begin to understand and address the problems surrounding this task, Hewlett-Packard Laboratories collaborated with MIT Libraries over two years to develop DSpace, an open source institutional repository software system. This paper describes DSpace in the context of the Open Archival Information System (OAIS) reference model. Particular attention is given to the preservation aspects of DSpace, and the current status of the DSpace system with respect to addressing these aspects. The reasons for various design decisions and trade-offs that were necessary to develop the system in a timely manner are given, and directions for future development are explored. While DSpace is not yet a complete solution to the problem of preserving digital research output, it is a production-capable system, represents a significant step forward, and is an excellent platform for future research and development.

This master thesis’s subject is to model an ABB contactor’s dynamics and to develop a hardware-in-the-loop simulation environment. The hardware-in-the-loop method utilizes computer models that are simulated in a real-time simulator. The real-time simulator is connected to hardware components. A contactor is an electrically controlled mechanical switching device and it is used in circuits where large currents can occur. In this thesis, the contactor is divided into three separate subsystems and models are developed for each of them. The three subsystems correspond to the contactor’s mechanics, electromagnetics and electronic components. Computer models are implemented in MATLAB and Simulink to realize the subsystems. The hardware part, of the hardware-in-the-loop simulations, consists of electronic parts that are not modeled. To connect the hardware part to a real-time simulator, from dSPACE, a hardware interface was constructed. This report focuses on the modeling of the mechanics and the electromagnetics as well as the software implementations. The thesis work was carried out in collaboration with another student. The focuses of his report are the modeling of the electronics and the construction of the hardware interface. Validation of the hardware-in-the-loop simulations is done by using measurements collected from a real contactor. The conclusion is that the simulations of the contactor’s behavior correspond well with a real contactor.

Under the umbrella of Internet of Things (IoT) and Internet of Everything (IoE), new applications with diverse requirements have emerged and the traditional System-on-Chips (SoCs) were unable to support them. Hence, new versatile SoC architectures were designed, like chiplets and Cloud-of-Chips (CoC). A key component of every SoC, is the on-chip interconnect technology, which is responsible for the communication between Processing Elements (PEs) of a system. Network-on-Chip (NoC) is the current widely used interconnect technology, which is a layered, scalable approach. However, the last years the high structural complexity together with the functional diversity and the challenges (QoS, high latency, security) of NoC motivated the researchers to explore alternatives of it. One NoC alternative that recently gained attention is the Software Defined Network-on-Chip (SDNoC). SDNoC originated from Software Defined Network (SDN) technology, which supports the dynamic nature of future networks and applications, while lowering operating costs through simplified hardware and software. Nevertheless, SDN technology designed for large scale networks. Thus, in order to be ported to micro-scale networks proper alterations and new hardware architectures need to be considered.In this thesis, an exploration of how to embed the SDN technology within the micro scale networks in order to provide secure and manageable communication, improve the network performance and reduce the hardware complexity is presented. Precisely, the design and implementation of an SDNoC architecture is thoroughly described followed by the creation and evaluation of a novel SDNoC communication protocol, called MicroLET, in order to provide secure and efficient communication within system components. Furthermore, the security aspect of SDNoC constitutes a big gap in the literature. Hence, it has been addressed by proposing a secure SDNoC Group Key Agreement (GKA) communication protocol, called SSPSoC, followed by the exploration of Byzantine faults within SDNoC and the investigation of a novel Hardware Trojan (HT) attack together with a proposed detection and defend method.

I present in this thesis a fluid flow and heat transfer model for porous media using the lattice Boltzmann method (LBM). A computer simulation of this process has been developed and it is written using MATLAB software. The simulation code is based on a two dimensional model, D2Q9. Three physical experiments were designed to prove the simulation model through comparision with numerical results. In the experiments, physical properties of the air flow and the porous media were used as input for the computer model. The study results are not conclusive but show that the LBM model may become a reliable tool for the simulation of natural convection heat transfer in porous media. Simulations leading to improved understanding of the processes of air flow and heat transfer in porous media may be important into improving the efficiency of methods of air heating or cooling by passing air through fragmented rock.

Resumo: O aumento exponencial da produção de dados e informações científicas está diretamente associado à evolução das tecnologias digitais de informação e comunicação e, diante desse cenário, percebe-se a necessidade de implementação pelas instituições de ambientes informacionais digitais que possam reuni-los, organizá-los, disseminá-los e preservá-los. Os repositórios institucionais, objetos de estudo dessa pesquisa, são ambientes potenciais para tais ações; sua implementação, entretanto, deve atender as necessidades informacionais de seu público-alvo, tornando-se necessária a aplicação de métodos, técnicas e atributos que promovam a encontrabilidade da informação científica. Com o objetivo de verificar se os repositórios institucionais têm sido implementados a partir de atributos que viabilizem a encontrabilidade da informação pelos sujeitos informacionais, este estudo utiliza como referência os repositórios institucionais das três universidades estaduais do estado de São Paulo - USP, UNESP e UNICAMP. Para viabilizar o cumprimento dos objetivos da pesquisa, é utilizado o método quadripolar que permite dinamicidade e flexibilidade para o desenvolvimento do estudo por meio de seus quatro polos: epistemológico, teórico, técnico e morfológico. O polo epistemológico abordou o paradigma pós-custodial da Ciência da Informação e a Pós-Fenomenologia para fundamentar o estudo, epistemologicamente. O polo teórico permitiu buscar aportes relacionados às temáticas que permeiam o objeto de pesq... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The exponential increase in the production of scientific data and information is directly associated with the evolution of digital information and communication technologies and, in view of this scenario, it is noticed the need for institutions to implement digital information environments that can bring them together, organize them, disseminate and preserve them. Institutional repositories, objects of study of this research, are potential environments for such actions; its implementation, however, must meet the information needs of its target audience, making it necessary to apply methods, techniques and attributes that promote the finding of scientific information. With the objective of verifying that institutional repositories have been implemented based on attributes that enable information to be found by information subjects, this study uses as reference the institutional repositories of the three state universities of the state of São Paulo - USP, UNESP and UNICAMP. In order to achieve the objectives of the research, the four-pole method is used, which allows dynamicity and flexibility for the development of the study through its four poles: epistemological, theoretical, technical and morphological. The epistemological pole addressed the post-custodial paradigm of Information Science and Post-Phenomenology to support the study, epistemologically. The theoretical pole allowed the search for contributions related to the themes that permeate the research object, namely: Di... (Complete abstract click electronic access below)

Nos últimos anos observa-se uma maior valorização do patrimônio cultural brasileiro, principalmente no que tange as ações voltadas para salvaguardar o patrimônio imaterial. O registro de práticas, saberes, festividades e outras manifestações culturais não são mais restritas às ações de reprodução de práticas culturais, mas também resulta na produção de diversos registros bibliográficos, fotográficos, fílmicos e outros documentos em diversos suportes que capturam, registram e possibilitam o conhecimento das informações presentes nestas atividades. O uso cada vez mais frequente das mídias tecnológicas, principalmente à internet, enquanto canal de comunicação e divulgação do patrimônio cultural, festividades, entre outros eventos, implica no surgimento de muitas imagens, vídeos e produções bibliográficas sobre determinadas manifestações culturais que podem ser encontradas na rede e estão disponíveis para acesso público, porém a recuperação deste material enquanto fonte de informação se dá de forma aleatória, pois não foram observados alguns requisitos necessários para a disponibilização destes no ciberespaço. Busca-se com o desenvolvimento desta pesquisa possibilitar maior visibilidade ao setor cultural Mato-Grossense, por meio de um repositório digital para armazenamento e divulgação de documentos, vídeos, sons e outras produções advindas de projetos voltados para a Economia Criativa e o Patrimônio Cultural Imaterial Mato-Grossense. Além de colaborar com a promoção e divulgação do patrimônio cultural imaterial, o Repositório Digital – Cultura do Mato, criado com o software DSpace, contribuirá com a preservação dos conhecimentos tradicionais ao mesmo tempo em que viabilizará o acesso a produção e consumo de informações sobre cultura no estado de Mato Grosso. No primeiro capítulo apresenta-se a introdução da pesquisa discorrendo sobre o porquê de seu desenvolvimento, os objetivos envolvidos e a metodologia aplicada. No segundo capítulo discorre-se sobre os conceitos e informações referentes ao Patrimônio Cultural, dando ênfase na Cultural Imaterial de Mato Grosso, pautando-se principalmente em documentos produzidos pelo IPHAN. O terceiro capítulo discorre sobre a o papel dos Repositórios na Gestão da Informação, focando a importância das Bibliotecas e Repositórios Digitais, bem como as contribuições oferecidas pelo uso do software DSpace no desenvolvimento destas Unidades de Informações Virtuais. O quarto capítulo compreende discussões a respeito do tratamento e representação de informações provenientes do Mapeamento da Cultura em Mato Grosso, o qual envolve projetos relacionados ao desenvolvimento da economia criativa mato-grossense, dos quais resultarão documentos digitais que deverão ser armazenados no repositório digital. O quinto capitulo apresenta a análise das funcionalidades do repositório, fornecendo informações sobre as questões que envolvem a instalação do software DSpace, o registro de comunidades, coleções e itens, e resultado dos testes com os recursos de busca do programa. O sexto capitulo é dedicado as considerações finais desta pesquisa. O desenvolvimento deste trabalho se pautará pelos princípios da pesquisa exploratória, funcionalista e qualitativa, pois suas técnicas permitem uma visão geral, a interpretação e a descrição dos objetos em análise. Por fim espera-se demonstrar os benefícios do emprego de tecnologias que envolvem a criação de um repositório digital, tanto no quesito armazenamento de informações existentes sobre a economia e o patrimônio cultural mato-grossense, quanto na recuperação, acesso e visibilidade destes recursos informacionais.
