A busca por informação de qualidade e compatível com a necessidade do usuário tem sido tratada como obsessão, atualmente. A utilização da Internet indicou novos modelos de armazenamento de informações, como os repositórios digitais, que têm sido utilizados em ambientes acadêmicos e de pesquisa como principal forma de autoarquivar e, principalmente, de disseminar informação, porém com uma estrutura de informação que sugere melhor descrição dos recursos do que a própria Web e indica uma melhor recuperação da informação nestes ambientes. Os repositórios ainda não estão aptos a recuperar informação de forma semântica e contextualizada. Os novos paradigmas de Internet sugerem utilização dos recursos de Web 2.0 e também de Web 3.0, permitindo, respectivamente, interatividade e também estrutura de informação semântica. Desta forma o objetivo desta pesquisa é melhorar o processo de recuperação da informação, apresentando uma proposta de modelo estrutural no contexto da Web Semântica, abordando o uso de recursos da Web 2.0 e Web 3.0 em repositórios digitais, que permita recuperação semântica da informação, através da construção de uma camada de informação chamada Representação Iterativa.

The search for quality information and compatible with the need of user has been treated as an obsession now. The use of the Internet indicated a new type of store information, such as digital repositories, which have been used in academic and research as the main way to autoarchive, and especially to disseminate information, but with an information structure that suggests a better description resources than the Web itself and indicates a better retrieval of information in these environments. The repositories are not yet able to retrieve information in a semantic and context. The new paradigm suggests the use of Internet resources of Web 2.0 as well as Web 3.0, allowing, respectively, interactivity, and also the structure of semantic information. Thus the objective of this research is to improve the process of information retrieval, with a proposed structural model in the context of the Semantic Web, addressing the use of Web 2.0 and Web 3.0 in digital repositories, enabling semantic retrieval of information through construction of a layer of information called Representação Iterativa. The model suggested and proposed ─ Representação Iterativa ─ you can adapt to the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate an iterative layer information, which allows feedback information, and semantic retrieval of information, through the structural model designed for repositories. The model suggested resulted in the realization of the thesis that through Representação Iterativa is possible to establish a process of semantic retrieval of information in digital repositories.

abstract: The following is a case study composed of three workflow investigations at the open source software development (OSSD) based Apache Software Foundation (Apache). I start with an examination of the workload inequality within the Apache, particularly with regard to requirements writing. I established that the stronger a participant's experience indicators are, the more likely they are to propose a requirement that is not a defect and the more likely the requirement is eventually implemented. Requirements at Apache are divided into work tickets (tickets). In our second investigation, I reported many insights into the distribution patterns of these tickets. The participants that create the tickets often had the best track records for determining who should participate in that ticket. Tickets that were at one point volunteered for (self-assigned) had a lower incident of neglect but in some cases were also associated with severe delay. When a participant claims a ticket but postpones the work involved, these tickets exist without a solution for five to ten times as long, depending on the circumstances. I make recommendations that may reduce the incidence of tickets that are claimed but not implemented in a timely manner. After giving an in-depth explanation of how I obtained this data set through web crawlers, I describe the pattern mining platform I developed to make my data mining efforts highly scalable and repeatable. Lastly, I used process mining techniques to show that workflow patterns vary greatly within teams at Apache. I investigated a variety of process choices and how they might be influencing the outcomes of OSSD projects. I report a moderately negative association between how often a team updates the specifics of a requirement and how often requirements are completed. I also verified that the prevalence of volunteerism indicators is positively associated with work completion but what was surprising is that this correlation is stronger if I exclude the very large projects. I suggest the largest projects at Apache may benefit from some level of traditional delegation in addition to the phenomenon of volunteerism that OSSD is normally associated with. / Dissertation/Thesis / Doctoral Dissertation Industrial Engineering 2017

Visando explorar como as empresas de consultoria especializadas em avaliação de impacto ambiental promovem a gestão do conhecimento, foram levantadas práticas adotadas por oito empresas atuantes neste ramo. O estudo procurou verificar se há relação entre a classificação das empresas no contínuo de Maister (1997) com as práticas e ferramentas propostas por Silva (2004), fundamentadas, por sua vez, no ciclo de aprendizado de Nonaka e Takeuchi (1995), com os repositórios de conhecimento utilizados pelas empresas e com suas experiências relacionadas à criação, troca e retenção de conhecimento. Utiliza-se como método de pesquisa a aplicação de entrevistas qualitativas com integrantes chaves destas organizações. Conclui-se que o nível de diversificação de atuação das consultorias, em relação a mercados e territórios, pode indicar quais ferramentas de GC são mais apropriadas para essas organizações. / In order to explore how environmental consulting companies specialized in environmental impact assessments promote knowledge management, practices adopted by companies operating in this field were raised. The study attempts to verify whether there is relationship between the classification of companies in the Maisters continuous (1997) and the practices and tools proposed by Silva (2004), based in turn in the cycle of learning proposed by Nonaka and Takeuchi (1995), with the knowledge repositories used by companies and their experiences related to knowledge creation, exchange and retention. It is used as the research method the application of qualitative interviews with key members of these organizations. The conclusion of this study is that the level of consultants diversification, regarding markets and territories, may indicate the most appropriate KM tools for these organizations.

Magister Bibliothecologiae - MBibl / In the academic world, open access institutional repositories (IRs) are beginning to play a vital role in storing and disseminating scholarly communication. Through this method, higher education institutions are able to showcase their intellectual outputs and to contribute to sharing and building knowledge. This evolutionary process of scholarly communication is an important feature of knowledge societies.Furthermore, IRs allow scholars to make known the research they are involved in,which can result in their academic reputation improving, as well as the reputations of the institutions they represent.The purpose of this study is to examine the processes of establishing IRs in the four tertiary education institutions in the Western Cape, which form part of the Cape Higher Education Consortium (CHEC). Within this consortium is the collaborative library project, the Cape Library Consortium (CALICO), which represents the four academic library services. The researcher investigated whether the four Western Cape Higher Education Institutions have established IRs and their experiences in doing so. They are examined in the light of the guidelines for successful IRs already established in the international professional literature on IRs. Throughout the study,the partnerships that are needed for the success of IRs, with a specific emphasis on the crucial role that the librarian might play in this regard, are a central focus.The study is a qualitative case study, relying on interviews with key informants from the four HEIs and analysing policy and other supporting documents. The study confirms comment in the literature that IRs evolve in “messy” and “spotty” ways. The key findings might be summarised in the form of four assertions:• “It is all about people”• Philosophical differences are significant • Context and history cannot be ignored • The role of the university library is ambiguous.It is hoped that the study of fledgling IR projects might provide insights useful to the broader IR research and professional literature.

As a safe long-term management of nuclear wastes, deep geological repositories (DGRs) have been proposed or currently being constructed in several countries. The host rocks in DGRs are saturated with water after the geological disposal facilities (GDFs) are closed and sealed. Significant gas can be generated due to several processes, e.g., the metal corrosion, water radiolysis or microbial reaction of organic materials, etc. The generated gas is anticipated to span throughout the long-term disposal of waste, which may jeopardize the stability of host rocks. Correspondingly, the performance of GDF will be affected since the host rocks provide a final impediment to the radionuclide transport. As gas migration in saturated host rocks is a highly coupled hydro-mechanical (HM) process, either gas-induced micro-fracturing or macro-fracturing may contribute to the development of preferential gas pathways, which needs to be concerned to ensure the feasibility and safety of geological disposal. Current numerical studies on the gas migration behavior devoted to explaining the experimental phenomena in the gas injection tests conducted on the rock materials, in which some behaviors still cannot be well represented, i.e., gas induced fracturing, volulme dilation, anisotropic radial deformation. Therefore, to better represent the actual physical process of preferential gas flow, two modelling frameworks, i.e., macroscopic HM framework and two-scale HM framework, are proposed in the PhD study. For the macroscopic HM framework, a double porosity model is firstly developed based on the dual continuum method, in which the volumetric strains of the porous continuum (PC) and fractured continuum (FC) are work-conjugated to the respective effective stress level. The treatment in two types of porosity allows us to capture that the opening/closure of the fractures is caused by the interaction between the dilation of the PC and the dilation of the FPM, which is beneficial to describe the gas induced fracturing in an implicit way. Then, an enriched embedded fracture model (EFM) is proposed to address the mechanical behavior of fractures. A hyperbolic relation of fracture deformability is incorporated into the rock matrix, as a result the fractured rock shows a nonlinear elastic behavior, which can capture the stiffness degradation due to fracture opening. The equivalent continuum method is provided to derive the effective compliance tensor, which includes the transverse isotropic matrix and two fracture sets. Using the enriched EFM with a three-dimensional (3D) geometry is able to capture the anisotropic radial deformation during gas migration. Although the macroscopic HM framework is able to capture the major HM behaviors related to preferential gas flow, the development of gas dilatant pathways is still represented in an implicit way. Therefore, a two-scale HM framework is developed to explicitly simulate the development of preferential gas pathways. Initiating from the periodically distributed microstructures with microcracks, the asymptotic homogenization method is used to derive the macroscopic governing equations coupled with the normalized damage variable. The time-dependent damage evolution law is obtained from the microscopic mechanical energy analysis for evolving microcracks. Both time effect and size effect are incorporated in the damage model that will affect the overall HM behavior of rocks. The developed two-scale HM framework with single gas flow can qualitatively capture important behaviors, such as the discrete pathways, localized gas flow, unstabilized fracture branching. More specifically, the simulated results demonstrates that the inter-connection of fractures from gas inlet to outlet is a prerequisite for gas breakthrough, accompanied by large amounts of gas flowing out of the sample and a rapid drop in gas injection pressure. Incorporating water flow in the two-scale framework allows the model to quantitatively reproduce the experimental phenomena observed in the laboratory air injection tests, such as gas pressure evolution and mechanical deformation. More importantly, the model exlpaines that the significant differences in controlling gas breakthrough and mechanical deformation are resulting from the arbitrary nature of microstructural heterogeneities. To account for the gas-water interaction in the two-scale HM framework, a fully coupled two-phase flow and elaso-damage model is developed to simulate the laboratory and in-situ gas injection experiments. The model can quantitatively capture the experimental behaviors, e.g., gas pressure evolution and non-desaturation phenomenon. Furthermore, model results show that the highly localized fracture pathways are the major places where gas and water interacts each other, and as a result the rock is still kept fully saturated. As a whole, the obtained numerical results are synthesized and analyzed, the pros and cons of the developed models are discussed. To better improve the model performance, some recommendations are proposed for the future studies.

Background. Maintainability of software products continues to be an area of im- portance and interest both for practice and research. The time used for maintenance usually exceeds 70% of the whole period of software development process. At present, there is a large number of metrics that have been suggested to indicate the main- tainability of a software product. However, there is a gap in validation of proposed source code metrics and the external quality of software maintainability. Objectives. In this thesis, we aim to catalog the proposed metrics for software maintainability. From this catalog we will validate a subset of commonly proposed maintainability indicators. Methods. Through a literature review with a systematic search and selection ap- proach, we collated maintainability metrics from secondary studies on software main- tainability. A subset of commonly metrics identified in the literature review were validated in a retrospective study. The retrospective study used a large open source software "Elastic Search" as a case. We collected internal source code metrics and a proxy for maintainability of the system for 911 bug fixes in 14 version (11 experi- mental samples, 3 are verification samples) of the product. Results. Following a systematic search and selection process, we identified 11 sec- ondary studies on software maintainability. From these studies we identified 290 source code metrics that are claimed to be indicators of the maintainability of a soft- ware product. We used mean time to repair (MTTR) as a proxy for maintainability of a product. Our analysis reveals that for the "elasticsearch" software, the values of the four indicators LOC, CC, WMC and RFC have the strongest correlation with MTTR. Conclusions. In this thesis, we validated a subset of commonly proposed source code metrics for predicting maintainability. The empirical validation using a popu- lar large-scale open source system reveals that some metrics have shown a stronger correlation with a proxy for maintainability in use. This study provides important empirical evidence towards a better understanding of source code attributes and maintainability in practice. However, a single case and a retrospective study are insufficient to establish a cause effect relation. Therefore, further replications of our study design with more diverse cases can increase the confidence in the predictive ability and thus the usefulness of the proposed metrics.
