  1. 16. Autonomic Management of Partitioners for SAMR Grid Hierarchies

    Författare :Henrik Johansson; Jarmo Rantakokko; Michael Thuné; Johan Steensland; Manish Parashar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Parallel structured adaptive mesh refinement methods decrease the execution time and memory usage of partial differential equation solvers by adaptively assigning computational resources to regions with large solution errors. These methods result in a dynamic grid hierarchy. LÄS MER

  3. 17. Hierarchical Modeling and Analysis of Real Time Systems

    Författare :Alexandre David; Wang Yi; Purush Iyer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science with specialization in Real Time Systems; Computer science; Datavetenskap;

    Sammanfattning : UPPAAL is a tool for model-checking real-time systems developed jointly by Uppsala University and Aalborg University. It has been applied successfully in case studies ranging from communication protocols to multimedia applications. The tool is designed to verify systems that can be modeled as networks of timed automata. LÄS MER

  4. 18. Rethinking Speculative Execution from a Security Perspective

    Författare :Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer architecture; speculative execution; processor; security; out-of-order execution; side-channel; microarchitectural replay; microarchitecture; Delay-on-Miss; Ghosts; Delay-on-Squash; Computer Science; Datavetenskap;

    Sammanfattning : Speculative out-of-order execution is one of the fundamental building blocks of modern, high-performance processors. To maximize the utilization of the system's resources, hardware and software security checks in the speculative domain can be temporarily ignored, without affecting the correctness of the application, as long as no architectural changes are made before transitioning to the non-speculative domain.

  5. 19. Fast and High-Quality Visibility Determination

    Författare :Rasmus Barringer; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer graphics; visibility; anti-aliasing; line sampling; ray tracing; rendering;

    Sammanfattning : Computer generated imagery is vital to the entertainment industry in the production of games and films, for example. It is also increasingly important for visualization in design, architecture, engineering, and medicine, to name a few. Improvements to rendering techniques come from a combination of improved algorithms and more powerful hardware. LÄS MER

  7. 20. Ease-of-Use in Public Transportation : A User Perspective on Information and Orientation Aspects

    Författare :Katrin Dziekan; Lars-Göran Mattsson; Brian D. Taylor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; public transportation; user perspective; psychology; public transportation planning; evaluation; newcomers in a city; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This interdisciplinary thesis combines psychological and transportation planning knowledge. Three main questions are investigated: 1) What concepts and ideas do people have with regard to a public transportation system (cognitive user perspective)?; 2) What orientation and information factors within the public transportation system enhance Ease-of-Use and make it simpler and more efficient to use public transportation in metropolitan areas?; 3) How can Ease-of-Use of a public transportation route be measured? A combination of qualitative and quantitative methods was used. LÄS MER
