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

    Author : Fredrik Persson; Pär Jönsson; Anders Eliasson; Ioannis Arvanitidis; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

    Author : Fredrik Persson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resonator; single-electron box; superconducting devices; decoherence; quantum capacitance; Sisyphus resistance; transmon; single-Cooper-pair box; qubit; rf-reflectometry;

    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.

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

    Author : Fredrik Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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

  5. 5. Event Based Sampling with Application to Spectral Estimation

    Author : Niclas Persson; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Event based sampling; Time based sampling; Tire pressure monitoring system;

    Abstract : In this thesis event based sampling, estimation of a single resonance frequency and the application indirect tire pressure monitoring system are studied.Event based sampling is an alternative to traditional uniform or equidistant sampling. In event based sampled systems, signals are sampled only when certain pre-defined events take place. READ MORE
