  2. 6. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz

    Author : Mohamed Sadek; Jens Bergström; Nils Hallbäck; Ulrich Krupp; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; ultrasonic fatigue testing; automotive steels; fatigue strength; stress intensity computation; crack growth; Materialteknik; Materials Engineering;

    Abstract : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. READ MORE

  4. 7. Quantum Holonomy for Many-Body Systems and Quantum Computation

    Author : Vahid Azimi Mousolou; Erik Sjöqvist; Rosario Fazio; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantum holonomy; geometric phase; quantum correlations; quantum phase transitions; quantum computation; Natural Science; Naturvetenskap; Physics; Fysik;

    Abstract : The research of this Ph. D. thesis is in the field of Quantum Computation and Quantum Information. A key problem in this field is the fragile nature of quantum states. READ MORE

  5. 8. Geometric and Topological Phases with Applications to Quantum Computation

    Author : Marie Ericsson; Ignacio Cirac; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; geometric phases; topological phases; quantum computation; mixed states; completely positive maps; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Quantum phenomena related to geometric and topological phases are investigated. The first results presented are theoretical extensions of these phases and related effects. Also experimental proposals to measure some of the described effects are outlined. READ MORE

  6. 9. Realtime & Development - modes of knowing design computation in architectural practice

    Author : Frans Magnusson; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design Methodology; Architectural Practice; Design Theory; Action Research; Computational Design; Design Computation; Design Systems; Project Workflow Management;

    Abstract : This thesis examines theoretical, methodological and organisational implications of design computation for architectural practice - from an insider perspective. It also proposes a conceptual model for knowing within this practice, in an approach that interrelates theory and actionable knowledge. READ MORE

  7. 10. Computational Aspects of Maass Waveforms

    Author : Fredrik Strömberg; Dennis A. Hejhal; Andreas Strömbergsson; David Farmer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Maass waveform; Congruence subgroup; Noncongruence subgroup; Multiplier system; Theta multiplier system; Eta multiplier system; real weight; Hecke operator; Involution; Dirichlet character; Spectral Theory; Computation; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

    Abstract : The topic of this thesis is computation of Mass waveforms, and we consider a number of different cases: Congruence subgroups of the modular group and Dirichlet characters (chapter 1); congruence subgroups and general multiplier systems and real weight (chapter 2); and noncongruence subgroups (chapter 3). In each case we first discuss the necessary theoretical background. READ MORE
