The relationship between Research Data Management and Virtual Research Environments

Van Wyk, Barend Johannes January 2018 (has links)
The aim of the study was to compile a conceptual model of a Virtual Research Environment (VRE) that indicates the relationship between Research Data Management (RDM) and VREs. The outcome of this study was that VREs are ideal platforms for the management of research data. In the first part of the study, a literature review was conducted by focusing on four themes: VREs and other concepts related to VREs; VRE components and tools; RDM; and the relationship between VREs and RDM. The first theme included a discussion of definitions of concepts, approaches to VREs, their development, aims, characteristics, similarities and differences of concepts, an overview of the e-Research approaches followed in this study, as well as an overview of concepts used in this study. The second theme consisted of an overview of developments of VREs in four countries (United Kingdom, USA, The Netherlands, and Germany), an indication of the differences and similarities of these programmes, and a discussion on the concept of research lifecycles, as well as VRE components. These components were then matched with possible tools, as well as to research lifecycle stages, which led to the development of a first conceptual VRE framework. The third theme included an overview of the definitions of the concepts ‘data’ and ‘research data’, as well as RDM and related concepts, an investigation of international developments with regards to RDM, an overview of the differences and similarities of approaches followed internationally, and a discussion of RDM developments in South Africa. This was followed by a discussion of the concept ‘research data lifecycles’, their various stages, corresponding processes and the roles various stakeholders can play in each stage. The fourth theme consisted of a discussion of the relationship between research lifecycles and research data lifecycles, a discussion on the role of RDM as a component within a VRE, the management of research data by means of a VRE, as well as the presentation of a possible conceptual model for the management of research data by means of a VRE. This literature review was conducted as a background and basis for this study. In the second part of the study, the research methodology was outlined. The chosen methodology entailed a non-empirical part consisting of a literature study, and an empirical part consisting of two case studies from a South African University. The two case studies were specifically chosen because each used different methods in conducting research. The one case study used natural science oriented data and laboratory/experimental methods, and the other, human orientated data and survey instruments. The proposed conceptual model derived from the literature study was assessed through these case studies and feedback received was used to modify and/or enhance the conceptual model. The contribution of this study lies primarily in the presentation of a conceptual VRE model with distinct component layers and generic components, which can be used as technological and collaborative frameworks for the successful management of research data. / Thesis (DPhil)--University of Pretoria, 2018. / National Research Foundation / Information Science / DPhil / Unrestricted

Förändringar av arbetssätt vid implementering av BIM : En kvalitativ studie av två traditionella projekteringars arbetssätt och tid- och resursplanering samt vilka förändringar som är nödvändiga vid implementering av BIM / Changes of ways of working in the implementation of BIM : A qualitative study of two traditional design processes ways of working and time and  resource planning, and what changes are necessary in the implementation of BIM

Jansson, Magnus, Knutsson, Kristian January 2012 (has links)
I en rapport från 2005 framtagen av FoU-Väst i samverkan med Centrum för management i byggsektorn (CMB) konstateras att en betydande del av allt slöseri i byggsektorn är kopplat till fel och konsekvenserna av dessa, med andra ord felkostnader. Studien visar att felkostnader står för cirka 10 % av ett projekts produktionskostnad.   Byggsektorn står nu, år 2012, inför förändringar i sitt arbetssätt för att minska antalet fel, öka kvaliteten och effektiviteten. BIM – Building Information Modeling, möjliggör ett smartare sätt att skapa, använda och förvalta information genom hela bygg- och förvaltningsprocessen. BIM ger möjligheten att anpassa informationen i varje delprocess och därigenom effektivisera arbetet. Det nya arbetssättet innebär ett livscykeltänk där information används på ett systematiskt och kvalitetssäkrat sätt i en objektbaserad 3D-modell.  Studiens syfte är att fastställa vilka arbetssätt som behöver förändras för att implementera BIM i ett av Skanskas distrikt i regionen Hus Stockholm Ombyggnad samt fastställa vilka kostnadsbesparingar beställare gör tack vare implementeringen. BIM består av mer än en datamodell. För att uppnå de nyttor BIM kan ge krävs förändrade processer och gemensamma begreppsmodeller. Processerna, organisationen och modelleringen av produkten måste planeras noggrant. Detta medför att mer resurser läggs i ett tidigt skede i projekteringen vilket krävs för att kravspecifikationen ska uppfyllas i ett BIM-projekt. Flera respondenter i studien ger uttryck för att fler och/eller utförligare informationsleveranser i systemskedet skulle höja kvaliteten på bygghandlingarna. Studien konstaterar att BIM-projektering kräver ett nära och öppet samarbete mellan, de för BIM-användingen aktuella aktörerna. / In a 2005 report written by FoU-Väst in collaboration with Centrum för management i byggsektorn (CMB) it is determined that a significant proportion of wastage in the construction sector is linked to defects and their impact, in other words costs of errors. The study shows that these costs are accounting for about 10 % of a project´s production costs.  Construction sector now, in 2012, face changes in their ways of working to reduce errors, increase quality and efficiency. BIM - Building Information Modeling, provides a smarter way to create, use and manage information throughout the construction and management process. BIM provides the ability to customize the information in each sub- process and thereby improve efficiency. The new ways of working involves a life- cycle thinking in which information is used in a systematic and quality assured manner in an object-based 3D model.  The study aims to determine the ways of working that needs to change to implement BIM in one of Skanska's district in the region Stockholm Hus Ombyggnad and identify cost savings clients make through the implementation. BIM consists of more than one data model. To achieve the benefits that BIM can provide, changes in processes and common conceptual models are required. Processes, the organization and modeling of the product must be carefully planned. This means that more resources are added in the early stages of the design process which is necessary to meet the specification of requirements in a BIM project. A number of respondents in the study reflect on the fact that additional and / or more detailed information deliveries during the schematic design phase would increase the quality of construction documents. The study finds that a BIM design process require near and open cooperation between the, to the BIM-use relevant participants.

Épistémologie de la conservation du patrimoine : ontologie d'un domaine, ergologie d'une discipline

Leveau, Pierre 13 December 2012 (has links)
Ce mémoire est une mise à jour philosophique du modèle conceptuel défini par Aloïs Riegl dans son ouvrage sur Le culte moderne des monuments. Pour faire cet aggiornamento, nous présentons dans une première partie ce modèle et l'énigme qu'il contient. Dans la deuxième, nous décrivons le paradigme que les premières communautés patrimoniales adoptèrent dans l'Entre-Deux-Guerres pour la résoudre, puis nous introduisons dans la troisième les concepts qui ancrent leur paradigme dans le monde actuel et nous formulons l'énigme qu'il pose maintenant aux professionnels. Historiquement, nous démontrons ainsi la continuité de l'institution patrimoniale, d'A. Riegl à nos jours. En dépouillant les archives de la Commission internationale de Coopération intellectuelle, nous prouvons que l'ONU et l'UNESCO n'ont pas créé les réseaux de conservation que nous connaissons, mais ont hérités de ceux que la SDN et la CICI tissèrent avant-guerre en fédérant les institutions et les associations qui existaient alors. Philosophiquement, nous mettons au jour le fondement ontologique et épistémologique de l'institution patrimoniale en étudiant différents modèles conceptuels. Nous expliquons comment le réalisme structural peut concilier les théories réalistes et constructivistes qui pourraient s'opposer ici et comment l'approche processus permet d'unifier ses secteurs sans nier les différences de nature qui existent entre ses objets. Notre thèse est que l'on peut modéliser le domaine en interconnectant les points de vue de ses acteurs. Pour l'établir, nous répondons à la question de savoir ce qu'est le patrimoine, comment fonctionne son institution et sur quoi se fonde sa conservation. / This doctoral thesis on epistemology of conservation is a philosophical update of the conceptual model defined by Alois Riegl in his book on The Modern Cult of Monuments. The first part presents the model and its riddle in order to perform this aggiornamento. The second part describes the paradigm adopted by the first heritage communities between the two world wars in their attempt to resolve it. The third part introduces the concepts that connect their paradigm with the present world and formulate the riddle challenging current professionals. The author proves the historic continuity of the heritage institution from A. Riegl to our days. By examining the archives of the International Committee on Intellectual Cooperation (ICIC), he demonstrates that the UN and UNESCO didn't create the heritage networks that we know today but that they originate from the networks of institutions and associations organized by the League of Nations and ICIC before World War I. Philosophically, he brings to light the ontological and epistemological foundation of the heritage institutions by studying several conceptual models. He explains how structural realism can reconcile realism with constructivism, even as they seem to be opposite theories, and alson how the processus approach can unify its parts without negating the differences of nature between its objects. His thesis is that almost all of the domain can be modelized by interconnecting the points of view of all its actors. To establish this point, he answer the following questions : what is heritage ? How does its institution function ? What is its conservation funded upon ?

La branche émotion, un modèle conceptuel pour l’intégration de la reconnaissance multimodale d’émotions dans des applications interactives : application au mouvement et `a la danse augmentée

Clay, Alexis 07 December 2009 (has links)
La reconnaissance d'émotions est un domaine jeune mais dont la maturité grandissante implique de nouveaux besoins en termes de modélisation et d'intégration dans des modèles existants. Ce travail de thèse expose un modèle conceptuel pour la conception d'applications interactives sensibles aux émotions de l'utilisateur. Notre approche se fonde sur les résultats conceptuels issus de l'interaction multimodale: nous redéfinissons les concepts de modalité et de multimodalité dans le cadre de la reconnaissance passive d'émotions. Nous décrivons ensuite un modèle conceptuel à base de composants logiciels s'appuyant sur cette redéfinition: la branche émotion, facilitant la conception, le développement et le maintien d'applications reconnaissant l'émotion de l'utilisateur. Une application multimodale de reconnaissance d'émotions par la gestuelle a été développée selon le modèle de la branche émotion et intégrée dans un système d'augmentation de spectacle de ballet sensible aux émotions d'un danseur. / Computer-based emotion recognition is a growing field which develops new needs in terms of software modeling and integration of existing models. This thesis describes a conceptual framework for designing emotionally-aware interactive software. Our approach is based upon conceptual results from the field of multimodal interaction: we redefine the concepts of modality and multimodality within the frame of passive emotion recognition. We then describe a component-based conceptual model relying on this redefinition. The emotion branch facilitates the design, development and maintenance of emotionally-aware systems. A multimodal, interactive, gesture-based emotion recognition software based on the emotion branch was developed. This system was integrated within an augmented reality system to augment a ballet dance show according to the dancer's expressed emotions.

Gestão da preservação de documentos arquivísticos digitais: proposta de um modelo conceitual / Management of the digital records preservation: conceptual model proposal.

Innarelli, Humberto Celeste 31 March 2015 (has links)
Busca apresentar a problemática da preservação de documentos arquivísticos digitais frente às teorias e práticas arquivísticas e às tecnologias da informação e da comunicação (TICs), com o intuito de identificar as variáveis que impactam diretamente as políticas de preservação dos documentos arquivísticos digitais. Busca ainda apoiar as bases conceituais da preservação digital no Brasil e instrumentalizar as instituições com vistas à implementação da preservação digital de seus documentos arquivísticos. Trabalha com a hipótese de que a gestão e a preservação inadequada dos documentos arquivísticas digitais - via de regra sob responsabilidade de administradores e profissionais das TICs sem interface com os arquivistas - coloca em risco o documento arquivístico digital e, consequentemente, a memória social de parte da história da humanidade. Propõe um modelo conceitual de gestão da preservação de documentos arquivísticos digitais aplicável a qualquer instituição, independentemente de seu porte, e o discute em relação às propostas desenvolvidas pelo projeto InterPARES. A análise do modelo conceitual permite identificar outros elementos em busca do aperfeiçoamento da gestão da preservação de documentos arquivísticos digitais. / Aims to present the problem concerning the digital records preservation facing theories and archivists practices and the information and communications technology (ICTs), looking to identify the variables that impact the digital records preservation policies. Aims to support the digital preservation conceptual bases in Brazil and equip institutions regarding an implementation in the digital preservation of their records. The essay is based upon the hypothesis that the improper preservation and management of digital records - mainly under the responsibility of administrators and ICTs professionals without interface with the archivists - risks the digital records and, consequently, the social memoir of a fraction of mankind\'s history. This work suggests a conceptual model in the preserve of digital records applicable to any institution, regardless of its size, discussing it on the proposals developed by the InterPARES project. The analysis of the conceptual model allows identifying other elements in searching of the improvement in the management of digital records preservation.

Caractérisations structurale et pétrophysique d'un système géothermique en contexte volcanique d'arc de subduction : exemple de l’archipel de Guadeloupe / Structural and petrophysical characterizations of a geothermal system in a subduction volcanic setting : Guadeloupe archipelago

Navelot, Vivien 31 October 2018 (has links)
La zone de Vieux-Habitants rassemble les indices permettant de supposer la présence d’un système hydrothermal de haute température. Les données géophysiques acquises pour la prospection de ce système ne suffisent pas à sa compréhension qui nécessite l’analyse d’analogues. Pour proposer un modèle de système géothermique de cette zone, une analyse multiscalaire de la déformation fragile et une caractérisation des propriétés pétrophysiques des formations volcaniques ont été ménées sur trois paléo systèmes. L’analyse des populations de fractures montre que leur organisation n’est pas régie par une seule loi mathématique. Les faciès volcano-sédimentaires sont peu déformés ou de manière très localisée contrairement aux laves dont les densités de fracturation sont fortes. L’analyse de la distribution des faciès hydrothermalisés par rapport à ces structures indique qu’à l’échelle kilométrique, certaines intersections de failles contrôlent le drainage des fluides et localisent les zones d’altération hydrothermale prononcée. Les faciès sont divisés en grands groupes en fonction de leur nature et de leur degré d’altération. Ils montrent une grande variabilité des propriétés pétrophysiques. A l’état sain, les laves d’une part et les faciès pyroclastiques et de coulées de débris d’autre part, constituent deux groupes bien distincts. L’altération hydrothermale induit une restructuration totale du squelette matriciel et du réseau poreux. Elle permet une forte atténuation du signal magnétique et le développement d’un groupe ayant des propriétés réservoirs intermédiaires en diminuant les propriétés réservoirs des dépôts volcano-sédimentaires et en améliorant celles des laves. Le modèle de réservoir ainsi disponible conjugue des éléments structuraux et des hétérogénéités lithologiques permettant le transfert rapide des fluides, alors que les propriétés matricielles d’origines primaire et secondaire vont plutôt contrôler les propriétés de stockage de fluide et de chaleur. / The Vieux-Habitants area gathers indicators allowing to suppose a high-temperature hydrothermal system. The interpretation of geophysical data acquired for the exploration of this system requires the analysis of analogues. Several hydrothermal paleo-systems were studied in order to propose a conceptual model of a geothermal system for the Vieux-Habitants area. Studies of these analogues are based on a multi-scale study of the brittle deformation and a petrophysical characterization of the different volcanic rocks. The organization of fractures indicates the occurrence of a characteristic scale for each level of observation. Volcano-sedimentary units are far less deformed compared to highly fractured lavas. The brittle deformation in volcano-sedimentary deposits is highly localized in fractured corridors. Some fault intersections control major fluid flow at the kilometer scale. Moreover, the most hydrothermalized rocks are localized in the vicinity of these intersections. Volcanic rocks are divided according to their mechanism of formation (lava, debris flow…) and their degree of alteration. They exhibit strong heterogeneities of petrophysical properties. Fresh rocks are separated in two distinct groups, on one side lavas and on the other side debris flows and pyroclastic deposits. Hydrothermal alteration produces mineralogical replacements involving a complete reorganization of both the matrix skeleton and the pore network. It is marked by a removal of magnetic signal, an increase of porosity and permeability in lavas and a decrease of these properties in debris flows and pyroclastic deposits. Therefore, hydrothermalized rocks form a group with intermediate reservoir properties between the two groups of fresh rocks. The reservoir model combines both structural components and lithological heterogeneities that allow an efficient fluid transfer, whereas the matrix properties of primary and secondary origins will rather control the fluid and heat storage properties.
