  1. 1. Improving implementation of graphical user interfaces for object-oriented knowledge-bases

    Författare :Olof Johansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Second generation knowledge-based systems have raised the focus of research from rulebased to model-based systems. Model-based systems allow knowledge to be separated into target domain model knowledge and problem solving knowledge. LÄS MER

  3. 2. Databasskydd

    Författare :Johan Axhamn; Per Jonas Nordell; Thomas Riis; Jens Schovsbo; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; protection of databases; database protection; copyright; database directive; legal protection for databases; intellectual property; unfair competition; databasskydd; upphovsrätt; databasdirektivet; rättsligt skydd för databaser; immaterialrätt; illojal konkurrens; Legal Science; rättsvetenskap;

    Sammanfattning : The capacity to assemble, store, and make available information in databases is ever growing. This development has accelerated in recent decades, driven by the advent and increased use of digital networks. Already at an early stage, it led to demands for legal protection of databases.

  4. 3. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

    Författare :Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. LÄS MER

  5. 4. Managing Migration Flows by processing Personal Data within the adequate Data Protection Instrument : Scoping Exercise between general and law enforcement Data Protection Rules applicable to Third Country Nationals

    Författare :Teresa Quintel; Maria Bergström; Wojciech Wiewiórowski; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; EU data protection; third country nationals; immigration; Directive EU 2016 680; Regulation EU 2018 1725; Europarätt; European Integration Law;

    Sammanfattning : In the aftermath of increased migration flows coming to Europe in 2015, the so-called migration crisis, irregular migration and related crimes such as migrant smuggling and human trafficking became a hotly debated topic on European Union (EU) level. The results of those discussions were the fortification of the EU’s external borders, the strengthening of the mandate of relevant EU Agencies and the establishment of new databases in the Area of Freedom, Security and Justice (AFSJ).

  7. 5. Modelling phase separation in Fe-Cr alloys : A continuum approach

    Författare :Thomas Barkar; John Ågren; Nele Moelans; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

    Sammanfattning : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. LÄS MER
