    Författare :Pontus Söderbäck; Jörgen Blomvall; Martin Singull; Stein-Erik Fleten; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The financial markets have an essential role in society. Further, these markets are constantly evolving. Therefore, models and methods have to be developed and adapted to the new market conditions to be useful for decisions. LÄS MER

  3. 17. Performance-aware Component Composition for GPU-based systems

    Författare :Usman Dastgeer; Christoph Kessler; Marco Danelutto; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis addresses issues associated with efficiently programming modern heterogeneous GPU-based systems, containing multicore CPUs and one or more programmable Graphics Processing Units (GPUs). We use ideas from component-based programming to address programming, performance and portability issues of these heterogeneous systems. LÄS MER

  4. 18. Server-Aided Privacy-Preserving Proximity Testing

    Författare :Ivan Oleinikov; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active security; MPC; privacy; secure proximity testing;

    Sammanfattning : Proximity testing is at the core of many Location-Based online Services (LBS) which we use in our daily lives to order taxis, find places of interest nearby, connect with people. Currently, most such services expect a user to submit his location to them and trust the LBS not to abuse this information, and use it only to provide the service. LÄS MER
