A common problem in the workplace is sharing digital documents with coworkers. Forsome companies the problem extends to wanting the documentskept internally backedup and controlling which people in the company has rights to read and revise certaindocuments.This paper shows different systems and models for access control, version control,and distribution of the documents that can be used to create asystem that solves theseproblems.One requirement for this system was a user interface where users can upload, down-load and manage access to their documents. Another requirement was a service thathandles version control for the documents, and a way to quickly connect and distributethe documents. The system also needed to be able to handle access control of the ver-sioned documents on document level, referred to as "fine grained access control" in thispaper.These models and systems were evaluated based on aspects of the access control mod-els, version control systems, and distribution systems andprotocols. After evaluating,appropriate selections were made to create a prototype to test the system as a whole.The prototype ended up meeting the goals that Nordicstationset for the project butonly with basic functionality. Functionality for retrieving any version from a docu-ments history, controlling access for the documents at document level, and a simpleweb based user interface for managing the documents. / Att enkelt dela dokument med arbetskollegor är något alla företag har ett behov utav.Ofta är dessa dokument interna och skall hållas inom företaget.

My independent work has been to modernize a user interface in a 10-year-old MVC Framework application used by Skärblacka mills within the BillerudKorsnäs Group. The concept of modernization also means increasing its quality; to replace older knowledge and technology with new and modern technology such as be able to click on the text of a checkbox that is considered to be more relevant for its time. The framework chosen for the implementation was ASP.NET Core MVC, which is an open source for the most common platforms. The implementation of the porting meant that server code that is well-functioning has been maintained to a large extent. JavaScript is also pretty much the same except in a few places. To get a good and durable structure, the application is layered in the form of 3 layers with Controller, BusinessLayer and Repository. The database with SQL Server is basically the same except that Identity has been introduced. To be able to communicate with the database, ORM EF Core has been chosen, which is a slim version of EF. A lot of what is in the old MVC framework has been redesigned because it is not supported in Core MVC. The application consists of an assembly with a logical development tree that consists of the files included in the application.Ajax has been used to get soft desktop-like updates.The application, which is complex with a lot of complicated things, made time run away. / Mitt självständiga arbete har varit att modernisera ett användargränssnittet i en 10 år gammal MVC Framework applikation som används av Skärblacka bruk inom BillerudKorsnäs koncernen. I begreppet modernisera ligger också innebörden att öka dess kvalité; att byta ut äldre kunskaper och teknik mot ny och modern teknik som t.ex. kunna klicka på texten till en checkbox som anses vara av mer relevans för sin tid. Det ramverk som valdes för implementationen var ASP.NET Core MVC som är ett open sourse för de vanligaste plattformarna. Genomförandet av porteringen innebar att serverkod som är väl fungerande har bibehållits i stora delar. Även JavaScript är i stort sett densamma förutom på några få ställen. För att få en bra och hållbar struktur är applikationen skiktad i form av 3 lager med Controller, BusinessLayer och Repository. Databasen med SQL Server är i stort sett densamma förutom att Identity har införs. För att kunna kommunicera med databasen har man valt ORM EF Core som är en slimmad version av EF. En hel del av det som finns i den gamla MVC framework är omgjort eftersom det stöds in i Core MVC. Applikationen består av en assembly med ett logiskt utvecklingsträd som utgörs av de filer som ingår i applikationen. Ajax har används för att få mjuka desktop liknade uppdateringar. Applikationen som är komplex med en hel del komplicerade saker gjorde att tiden rann iväg.

Die sichere Endlagerung hochradioaktiver Stoffe ist weltweit eine der großen Herausforderungen des 21. Jahrhunderts. Der abgebrannte Kernbrennstoff ist hoch-radiotoxisch und stellt somit eine Gefährdung für Mensch und Umwelt dar. Daher muss der radioaktive Abfall für bis zu einer Million Jahre von der Umwelt isoliert werden. International wird dafür die Endlagerung in tiefengeologischen Formationen favorisiert. Für ein solches Endlager für radioaktive Abfälle kommen in Deutschland Salz-, Ton- und Kristallinformationen in Frage, welche aufgrund der verschiedenen mineralogischen und geochemischen Bedingungen Radionuklide (RN) unterschiedlich stark immobilisieren. Wesentliche Prozesse sind dabei Ausfällung, Einbau in Festphasen und Sorption an Mineraloberflächen. Für eine belastbare Risikobewertung möglicher Endlagerstandorte sind geeignete Transportmodelle notwendig, welche auf umfangreiche thermodynamische Daten angewiesen sind. Hierfür sind insbesondere Studien zu Wechselwirkungen (WW) von RN mit Mineralphasen im Kristallingestein, d.h. Quarz, Feldspäten, Glimmern, nicht ausreichend verfügbar. Die minoren Actinide Am und Cm liegen in wässriger Lösung grundsätzlich im dreiwertigen Oxidationszustand vor. Außerdem werden unter den zu erwarteten reduzierenden Bedingungen in einem Endlager auch Np zu einem geringen und Pu zu einem nennenswerten Teil dreiwertig vorliegen. Daher beschäftigt sich der erste Teil der Arbeit mit den WW dreiwertiger Actiniden (An(III) = Am, Cm) mit Feldspäten. Der zweite Teil der Arbeit beschäftigt sich mit dem Einfluss von Elektrolyten auf die Rückhaltung von Actiniden an Mineraloberflächen. Dabei wurde zum einen der Einfluss des natürlich häufig auftretenden, anorganischen Liganden Sulfat auf die Sorption von An(III) an das Schichtsilikat (Glimmer) Muskovit untersucht, sowie in einem weiteren Beispiel der Einfluss der Elektrolytzusammensetzung auf die Sorption des Actinids Thorium an Muskovit untersucht. Th liegt in wässriger Lösung ausschließlich vierwertig vor und wird stark hydrolysiert, wodurch die Bildung polynuklearer Spezies begünstigt ist. Methodisch kommen in diesem Teil der Arbeit neben Oberflächenröntgenbeugung (SXRD) auch Alphaspektrometrie und Rasterkraftmikroskopie (AFM) zum Einsatz. Die Ergebnisse der Arbeit leisten einen signifikanten Beitrag zur realistischen Abschätzung der Mobilität drei- und vierwertiger Actiniden im Kristallingestein. Die Ergebnisse der Arbeit werden in Zukunft Simulationen des reaktiven Transports und somit die Auswahl eines geeigneten Standorts für ein Endlager für radioaktiven Abfall unterstützen.

There is a large number of biosignals that can be obtained from the human body. Repositories of biosignals are used for researchers in many studies as datasets. Datasets with clinical and personal information have many regulations and they are not accessible to everyone. Platforms with acquisition, recording and visualization of data are currently used in homecare systems for monitoring patients in an effcient way. Distant monitoring allows a good and prompt communication between patients and physicians. This work describes the design and development of a platform at hardware and software level for recording, storage, visualization and analysis of biosignals on the cloud. For the platform, IoT and Cloud Computing resources were used. Open-source and free software are considered for an easy and flexible enlargement of the system.

Data warehouse technology has been successfully integrated into the information infrastructure of major organizations as potential solution for eliminating redundancy and providing for comprehensive data integration. Realizing the importance of a data warehouse as the main data repository within an organization, this dissertation addresses different aspects related to the data warehouse architecture and performance issues. Many data warehouse architectures have been presented by industry analysts and research organizations. These architectures vary from the independent and physical business unit centric data marts to the centralised two-tier hub-and-spoke data warehouse. The operational data store is a third tier which was offered later to address the business requirements for inter-day data loading. While the industry-available architectures are all valid, I found them to be suboptimal in efficiency (cost) and effectiveness (productivity). In this dissertation, I am advocating a new architecture (The Hybrid Architecture) which encompasses the industry advocated architecture. The hybrid architecture demands the acquisition, loading and consolidation of enterprise atomic and detailed data into a single integrated enterprise data store (The Enterprise Data Warehouse) where businessunit centric Data Marts and Operational Data Stores (ODS) are built in the same instance of the Enterprise Data Warehouse. For the purpose of highlighting the role of data warehouses for different applications, we describe an effort to develop a data warehouse for a geographical information system (GIS). We further study the importance of data practices, quality and governance for financial institutions by commenting on the RBC Financial Group case. v The development and deployment of the Enterprise Data Warehouse based on the Hybrid Architecture spawned its own issues and challenges. Organic data growth and business requirements to load additional new data significantly will increase the amount of stored data. Consequently, the number of users will increase significantly. Enterprise data warehouse obesity, performance degradation and navigation difficulties are chief amongst the issues and challenges. Association rules mining and social networks have been adopted in this thesis to address the above mentioned issues and challenges. We describe an approach that uses frequent pattern mining and social network techniques to discover different communities within the data warehouse. These communities include sets of tables frequently accessed together, sets of tables retrieved together most of the time and sets of attributes that mostly appear together in the queries. We concentrate on tables in the discussion; however, the model is general enough to discover other communities. We first build a frequent pattern mining model by considering each query as a transaction and the tables as items. Then, we mine closed frequent itemsets of tables; these itemsets include tables that are mostly accessed together and hence should be treated as one unit in storage and retrieval for better overall performance. We utilize social network construction and analysis to find maximum-sized sets of related tables; this is a more robust approach as opposed to a union of overlapping itemsets. We derive the Jaccard distance between the closed itemsets and construct the social network of tables by adding links that represent distance above a given threshold. The constructed network is analyzed to discover communities of tables that are mostly accessed together. The reported test results are promising and demonstrate the applicability and effectiveness of the developed approach.

Clay formations are investigated worldwide as potential host rock for the deep geological disposal of high-level radioactive waste (HLW). Usually bentonite is preferred as the buffer and backfill material in the disposal system. In the disposal of HLW, heat emission is one of the most important issues as it can generate a series of complex thermo-hydro-mechanical (THM) processes in the surrounding materials and thus change the material properties. In the context of safety assessment, it is important to understand the thermally induced THM interactions and the associated change in material properties. In this work, the thermally induced coupled THM behaviours in the clay host rock and in the bentonite buffer as well as the corresponding coupling effects among the relevant material properties are numerically analysed. A coupled non-isothermal Richards flow mechanical model and a non-isothermal multiphase flow model were developed based on the scientific computer codes OpenGeoSys (OGS). Heat transfer in the porous media is governed by thermal conduction and advective flow of the pore fluids. Within the hydraulic processes, evaporation, vapour diffusion, and the unsaturated flow field are considered. Darcy’s law is used to describe the advective flux of gas and liquid phases. The relative permeability of each phase is considered. The elastic deformation process is modelled by the generalized Hooke’s law complemented with additional strain caused by swelling/shrinkage behaviour and by temperature change. In this study, special attention has been paid to the analysis of the thermally induced changes in material properties. The strong mechanical and hydraulic anisotropic properties of clay rock are described by a transversely isotropic mechanical model and by a transversely isotropic permeability tensor, respectively. The thermal anisotropy is described by adoption of the bedding-orientation-dependent thermal conductivity. The dependency of the thermal conductivity on the degree of water saturation, the dependency of the thermal effects on the water retention behaviour, and the dependency of the effects of the pore pressure variation on the permeability and the anisotropic swelling/shrinkage behaviour have been intensively analysed and the corresponding numerical models to consider those coupling effects have been developed. The developed numerical model has been applied to simulate the laboratory and in situ heating experiments on the bentonite and clay rock at different scales. Firstly the laboratory heating experiment on Callovo-Oxfordian Clay (COX) and the laboratory long-term heating and hydration experiment on MX80 pellets were simulated. Based on the knowledge from the numerical analysis of the laboratory experiments, a 1:2 scale in situ heating experiment of an integrated system of the bentonite engineered barrier system (EBS) in the Opalinus Clay host rock was simulated. All the relevant operation phases were considered in the modelling. Besides, the modelling was extended to 50 years after the heat shut-down with the aim of predicting the long-term behaviours. Additionally, variation calculations were carried out to investigate the effects of the storage capacity of the Opalinus Clay on the thermally induced hydraulic response. In the long-term modelling, the effects of different saturated water permeabilities of buffer material on the resaturation process were analysed. Based on the current researches and model developments, the observed THM behaviours of the bentonite buffer and the clay rock, that is, the measured evolution of temperature, pore pressure, humidity, swelling pressure, and so on in the laboratory and in situ experiments can be reproduced and interpreted well. It is proved that by using both a non-isothermal multiphase flow model and a non-isothermal Richards flow model combined with the corresponding thermal and mechanical models, the major THM behaviours can be captured. It is validated that the developed model is able to simulate the relevant coupled THM behaviours of clayey material under the well-defined laboratory conditions as well as under the complex natural disposal conditions.

Institutional repositories have been introduced as an innovative and alternative technology for scholarly communication and have received considerable attention from scholars across disciplines and around the globe. While some universities in Thailand have developed and implemented institutional repositories for nearly a decade, knowledge of the acceptance and use of institutional repositories on the individual level in the country remains limited. As an insufficient knowledge of technology acceptance and adoption at the individual level is considered partially responsible for the underutilization of innovation or of information system implementation, this study seeks to uncover knowledge regarding the level of institutional repository acceptance and use. This study applied the unified theory of acceptance and use of technology (UTAUT) model and the model of faculty members' self-archiving behavior to investigate factors affecting faculty acceptance and use of university-based institutional repositories. The study employed a mixed methods approach involving a survey followed by semi-structured, one-to-one interview. This study confirms that the success of university-based institutional repositories depends not on a single factor but on multiple factors. The results of the study show that performance expectancy, social influence, and resistance to change were direct determinants of faculty members' intention to use institutional repositories. Additionally, behavioral intention and altruism were found to be the main determinants of actual usage behavior. The findings of this study imply that education in and promotion of open access and institutional repositories are essential and can play an important role in the adoption of institutional repositories. Finally, this study suggests that sustained dialogue and collaborative efforts among faculty members (as contributors and users), libraries/librarians (as institutional repository developers and managers), and other stakeholders within communities are essential for the adoption and success of university-based institutional repositories.
