  1. 1. Microwave Breakdown: Physics and Applications

    Författare :Ulf Jordan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resonators; breakdown plasma; waveguides; microwave breakdown; metal wedges; HPM protection;

    Sammanfattning : Theories for microwave breakdown in gases, with emphasis on Air, are presented in this thesis. Underlying physical processes are described together with models suitable for scientific research and technical development. LÄS MER

  2. 2. On the breakdown of regularity of invariant curves in quasi-periodically forced systems

    Författare :Thomas Ohlson Timoudas; Kristian Bjerklöv; Joaquim Puig; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamical systems; strange attractors; Schrödinger cocycles;

    Sammanfattning : In this thesis we study the process of torus collisions in one-parameter families of quasi-periodically forced dynamical systems. Specifically, we study the process whereby two invariant curves (homeomorphic to circles), one attracting and one repelling, bifurcate into a strange non-chaotic attractor. LÄS MER

  3. 3. Breakdown situations in dialogues between humans and socially intelligent agents

    Författare :Maitreyee Tewari; Helena Lindgren; Kai-Florian Richter; Olov Engwall; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dialogues; Breakdown Situations; Focus Shift; Human-Centric Artificial Intelligence; Engeström’s Activity Triangle; We-Intention; Argumentation-Based Dialogues; Grice’s Cooperative Principle; Communicative Functions; Wizard-of-Oz; User Studies; Thematic Analysis; Sequence Organisation; Computer Science; datalogi;

    Sammanfattning : Dialogues between humans are complex due to the challenges in predicting how they will unfold as people may want to achieve different purposes. For instance, to act together, they co-create a common goal; to learn, they co-create knowledge; to build relationships, they share emotions and beliefs. LÄS MER

  4. 4. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields

    Författare :Joel Rasch; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corona; inhomogeneous fields; multipactor; Microwave breakdown;

    Sammanfattning : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.

  5. 5. Modelling and evaluation of the effects of traffic safety measures Comparative analysis of driving assistance systems and road infrastructure

    Författare :Meng Lu; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vägtransportteknik; GRA; Road transport technology; grey relational analysis; driving assistance systems; traffic safety principle; quantitative causal chain; comparative analysis; QCC model; road infrastructure; road traffic safety;

    Sammanfattning : Improvement of road traffic safety is an important policy issue. Various categories of meas-ures are available to effectuate this. The thesis focuses on two categories: road infrastructure and driv-ing assistance systems. LÄS MER
