  1. 1. Fractal superconducting resonators for the interrogation of two-level systems

    Författare :Sebastian Erik de Graaf; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cooper-pair box; decoherence; electron spin resonance; two-level systems; atomic force microscopy; quasiparticles; near-field scanning microwave microscopy; Superconducting resonators; circuit quantum electrodynamics;

    Sammanfattning : In this thesis we use high-Q superconducting thin-film microwave resonators to interact with several types of quantum mechanical two-level systems. Such a resonator is used as the central building block in a cryogenic near-field scanning microwave microscope (NSMM) to reach a completely new regime of NSMM operation. LÄS MER

  2. 2. Innovation under pressure Reclaiming the micro-level exploration space

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Katarina Lund Stetler; Mats Magnusson; Jens Hemphälä; Salomo Sören; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ambidexterity; exploration; exploitation; creativity; innovation; micro-level exploration space; operational level; operations; operational effectiveness; employee; lean; lean thinking; process management; streamlining; flow; Machine Design; Maskinkonstruktion;

    Sammanfattning : Research & Development (R&D) departments are becoming increasingly structured and routine-based, with tight schedules and daily follow-ups. This way of working stems from increased demands for delivering products to customers quickly and with high quality at a low price. LÄS MER

  3. 3. Maximal Unitarity at Two Loops A New Method for Computing Two-Loop Scattering Amplitudes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. LÄS MER

  4. 4. Exilens dilemma: att stanna eller att återvända : Beslut i Sverige av polska kvinnor som överlevde KZ-lägret Ravensbrück och räddades till Sverige 1945-1947

    Detta är en avhandling från Växjö, Kalmar : Linnaeus University Press

    Författare :Wirginia Bogatic; Lars Olsson; Hans-Åke Persson; Mattias Tydén; [2010]
    Nyckelord :HUMANIORA; HUMANITIES; Life story; macro level; micro level; meso level; Koselleck; realm of experience; expectations; Poland; women; surviving; concentration camp; Ravensbrück; collective memory; sociological generation; identity; migration; exile; refugees; World War II; rescue operation; oral history; HUMANITIES and RELIGION History and philosophy subjects History subjects History; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Historieämnen Historia; Historia; History;

    Sammanfattning : This thesis is about the intersection of great narratives and individual decisions. In the intersection, the dilemma of exile is discussed: to remain in exile or return to one’s homeland. LÄS MER

  5. 5. Two-Level Multi-Objective Genetic Algorithm for Risk-Based Life Cycle Cost Analysis

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Yamur Al-Douri; Uday Kumar; Jan Lundberg; Hussan Hamodi; Ahmed Al-Dubai; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial intelligence AI ; Life cycle cost LCC ; Machine learning ML ; Multi-objective genetic algorithm MOGA ; Risk-based life cycle cost LCC ; Tunnel fans; Two-level system.; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Artificial intelligence (AI) is one of the fields in science and engineering and encompasses a wide variety of subfields, ranging from general areas (learning and perception) to specific topics, such as mathematical theorems. AI and, specifically, multi-objective genetic algorithms (MOGAs) for risk-based life cycle cost (LCC) analysis should be performed to estimate the optimal replacement time of tunnel fan systems, with a view towards reducing the ownership cost and the risk cost and increasing company profitability from an economic point of view.
