  1. 31. Quasiparticles in the Quantum Hall Effect

    Författare :Janik Kailasvuori; Thors Hans Hansson; Jan Myrheim; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum Hall effect; quasiparticles; noncommutative Chern-Simons theory; nonabelian statistics; thin torus; p-wave superconductivity; topology; index theory; effective gauge fields; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : The fractional quantum Hall effect (FQHE), discovered in 1982 in a two-dimensional electron system, has generated a wealth of successful theory and new concepts in condensed matter physics, but is still not fully understood. The possibility of having nonabelian quasiparticle statistics has recently attracted attention on purely theoretical grounds but also because of its potential applications in topologically protected quantum computing.

  3. 32. Demand-Driven Static Backward Program Slicing Based on Predicated Code Block Graphs

    Författare :Husni Khanfar; Björn Lisper; Hans Hansson; Saad Mubeen; Daniel Hedin; Welf Löwe; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Static Program Analysis; Static Program Slicing; Control Dependency;

    Sammanfattning : Static backward program slicing is a technique to compute the set of program statements, predicates and inputs that might affect the value of a particular variable at a program location. The importance of this technique comes from being an essential part of many critical areas such as program maintenance, testing, verification, debugging, among others. LÄS MER

  4. 33. Non-local behaviour from local interactions

    Författare :Thomas Kvorning; Thors Hans Hansson; Ady Stern; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : With the discovery of the quantum Hall effect more than thirty years ago, a whole new field emerged—that of topological quantum matter. This field is now a very mature one, and many different aspects are covered in the literature. LÄS MER

  5. 34. Applying configuration management techniques to component-based systems

    Författare :Magnus Larsson; Hans Hansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Sammanfattning : Building software from components, rather than writing the code from scratch has several advantages, including reduced time to market and more efficient resource usage. However, component-based development without consideration of all the risks and limitations involved may give unpredictable results, such as the failure of a system when a component is used in an environment for which it was not originally designed.

  7. 35. Access Control for Secure Industry 4.0 Industrial Automation and Control Systems

    Författare :Björn Leander; Hans Hansson; Aida Causevic; Mikael Asplund; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : A significant part of our daily lives is dependent on the continuous operation of Industrial Automation and Control Systems (IACS). They are used to control the processes of delivering electricity and clean water to our households, to run and supervise manufacturing industries that produce things we use every day. LÄS MER
