  2. 1. Holonomy in Quantum Information Geometry

    Author : Ole Andersson; Ingemar Bengtsson; Boris Shapiro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik; Physics;

    Abstract : In this thesis we provide a uniform treatment of the two most popular non-adiabatic geometric phases for dynamical systems of mixed quantum states, namely those of Uhlmann and of Sjöqvist et al. We develop a holonomy theory for the latter which we also relate to the already existing theory for the former. READ MORE

  4. 2. Generic distribution support for programming systems

    Author : Erik Klintskog; Seif Haridi; Peter von Roy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; computer sicence; Datavetenskap; Computer science; Datavetenskap;

    Abstract : This dissertation provides constructive proof, through the implementation of a middleware, that distribution transparency is practical, generic, and extensible. Fault tolerant distributed services can be developed by using the failure detection abilities of the middleware. READ MORE

  5. 3. Studies of fermion masses in Gauge theories

    Author : Bengt-Åke Lindholm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : The Electroweak Standard Model of particle physics has proved to be avery successful theory. Nevertheless several questions have been raised dueto shortcomings of the model. The most outstanding question in this modelconcerns the origin of masses of the elementary particles. Eventually wehope that a more fundamental theory will explain the masses. READ MORE

  6. 4. Towards a Viscoelastic Model for Phase Separation in Polymer Modified Bitumen

    Author : Jiqing Zhu; Niki Kringos; Jean-Pascal Planche; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer modified bitumen; storage stability; viscoelastic phase separation; PMB model; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : In this thesis, a review is given on the most popular polymers used today for polymer modification of bitumen. Furthermore, the development of a model for phase separation in polymer modified bitumen (PMB) is proposed, that will enable a better control and understanding of PMB phase behaviour, allowing thus to enhanced long-term performance.

  7. 5. A comprehensive study of resistor-loaded planar dipole antennas for ground penetrating radar applications

    Author : Disala Uduwawala; Martin Norgren; Olav Breinbjerg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground penetrating radar; buried object detection; dipole antennas; FDTD methods; broadband properties; baluns; simulation; optimal design; lossy media; dispersive media; clutter.; Electrical engineering; Elektroteknik;

    Abstract : Ground penetrating radar (GPR) systems are increasingly being used for the detection and location of buried objects within the upper regions of the earth’s surface. The antenna is the most critical component of such a system. READ MORE
