  1. 1. Dynamic enforcement of decentralized security policies

    Författare :Jonas Magazinius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic; enforcement; security; policies; decentralized;

    Sammanfattning : This thesis explores defining security policies in a decentralized setting and dynamic methods of enforcing such policies. In a decentralized setting, principals are free to trust or distrust other principals. The key challenge is to provide possibilities for expressing and enforcing expressive decentralized policies.

  3. 2. Matematiska resonemang i en lärandemiljö med dynamiska matematikprogram

    Författare :Mats Brunström; Kenneth Ruthven; Arne Engström; Anne Berit Fuglestad; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical reasoning; Task design; Dynamic mathematics software; matematiska resonemang; uppgiftsdesign; dynamiska matematikprogram; Matematik; Mathematics;

    Sammanfattning : The overall problem that formed the basis for this thesis is that students get limited opportunity to develop their mathematical reasoning ability while, at the same time, there are dynamic mathematics software available which can be used to foster this ability. The aim of this thesis is to contribute to knowledge in this area by focusing on task design in a dynamic software environment and by studying the reasoning that emerges when students work on tasks in such an environment.

  4. 3. Modeling Complex Engines as Dynamic Powertrain Members

    Författare :Sixten Berglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle; diesel engine; simulation; supercharging; drivability; toolbox; fuel economy; transient; modeling; turbocharging; control system; powertrain; emissions; performance; dynamic; system;

    Sammanfattning : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. LÄS MER

  5. 4. Dynamic Visual Learning

    Författare :Joakim Johnander; Michael Felsberg; Martin Danelljan; Nicholas Wickström; Bernt Schiele; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Autonomous robots act in a \emph{dynamic} world where both the robots and other objects may move. The surround sensing systems of said robots therefore work with dynamic input data and need to estimate both the current state of the environment as well as its dynamics. LÄS MER

  7. 5. Dynamic configuration in a distributed environment

    Författare :Yngve Larsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes an implementation of the PEPSy paradigm and distinguishes between the different types of changes occurring in a distributed system, and how the many complicating issues of distribution affect our ability to perform these changes.We also compare our implementation with known systems from both the distributed programming and software engineering communities.
