  1. 1. A Study of Factors Affecting the Particle Size for Water Atomised Metal Powders

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fredrik Persson; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; metal powders; particle size; modelling; viscosity; surface tension;

    Abstract : The production of metal powders by water atomisation is a well established process, which can be used to produce a wide range of particle sizes. A careful control of the particle size distribution is necessary, to atomise powders with a high quality and at a low production cost. READ MORE

  2. 2. Fast dynamics and measurements of single-charge devices

    University dissertation from Chalmers University of Technology

    Author : Fredrik Persson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lågtemperaturfysik; Low temperature physics; Mesoskopisk fysik; Mesoscopic physics; Supraledning; Superconductivity; single-electron box; Sisyphus resistance; single-Cooper-pair box; quantum capacitance; rf-reflectometry; resonator; transmon; qubit; superconducting devices; decoherence;

    Abstract : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits. By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator. READ MORE

  3. 3. Studies of Fusion Oncogenes and Genomic Imbalances in Human Tumors

    University dissertation from Chalmers University of Technology

    Author : Fredrik Persson; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer genetics; fusion oncogene; gene amplification; array CGH; PLAG1; HMGA2; FGFR1; MDM2; pleomorphic adenoma; carcinoma ex pleomorphic adenoma; liposarcoma;

    Abstract : Cancer is a genetic disease caused by mutations and chromosome rearrangements affecting oncogenes and tumor suppressor genes in particular. Molecular analyses of recurrent translocations in hematological disorders, as well as in certain solid tumor types, have shown that they frequently result in fusion oncogenes. READ MORE

  4. 4. Studies of the Laser-Induced Exciplex Fluorescence Technique for Applications in Spray Research

  5. 5. Trade, Competition and Productivity

    University dissertation from Department of Economics, Lund Universtiy

    Author : Fredrik Wilhelmsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; productivity; Trade; exports; food industry; market power; developing countries; trade preferences; CEEC; EU; Europe Agreements; Handel;

    Abstract : This thesis consists of four papers on trade, competition and productivity with particular emphasis on the effects of various aspects of the deepening and widening of the European Union. The first paper Trade Creation, Diversion and Displacement of the EU Enlargement Process provides an assessment of the effects of the EU enlargement process on trade. READ MORE
