  2. 16. A Tactile Resonance Sensor System for Detection of Prostate Cancer ex vivo : Design and Evaluation on Tissue Models and Human Prostate

    Author : Anders P Åstrand; Britt M Andersson; Ville Jalkanen; Olof A Lindahl; E. Göran Salerud; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; elektronik;

    Abstract : Background The most common form of cancer among males in Europe and the USA is prostate cancer, PCa. Surgical removal of the prostate is the most common form of curative treatment. READ MORE

  4. 17. Four applications of stochastic processes : Contagious disease, credit risk, gambling and bond portfolios

    Author : Patrik Andersson; Andreas Nordvall Lagerås; Håkan Andersson; Stewart N. Ethier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stochastic processes; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : This thesis consists of four papers on applications of stochastic processes. In Paper I we study an open population SIS (Susceptible - Infective - Susceptible) stochastic epidemic model from the time of introduction of the disease, through a possible outbreak and to extinction. The analysis uses coupling arguments and diffusion approximations. READ MORE

  5. 18. Detecting Inclusions in a Silicone Rubber Phantom Using Standing Lamb Waves and Multiple Frequency Footprints

    Author : Ulf G Jonsson; Britt Andersson; Olof A Lindahl; Jacques Ohayon; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; Silicone rubber; Impedance; Resonance; Lamb waves; Phantom; Electronics; elektronik;

    Abstract : The thesis deals with one major question: is it possible, using one piezoelectric sensor/vibrator, to detect a hard inclusion in a silicone rubber phantom? The question was approached with an open mind and the task was subdivided into three clearly identifiable parts: characterization of the piezoelectric sensor/vibrator (paper I), creating a model of the visco-elastic properties of a tissue-like material (phantom) in contact with the sensor/vibrator (paper II), and to detect the presence of a hard inclusion in the phantom (paper III). All vibrations of the sensor/vibrator and phantom was modeled using a finite element method (FEM). READ MORE

  6. 19. Improving health with and for individuals with schizophrenia using a learning health system approach : From idea to daily practice

    Author : Andreas Gremyr; Ann-Christine Andersson; Boel Andersson-Gäre; Johan Thor; Ulf Malm; Graham Martin; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coproduction; Learning Health Systems; Schizophrenia; Severe Mental Illness; Psychiatry; Quality Improvement; Improvement Science; Complex Adaptive Systems;

    Abstract : Psychotic disorders like schizophrenia have a typical onset in early adulthood with symptoms of hallucinations and disturbances of thought. Despite knowledge on what constitutes effective schizophrenia care, more than 70% of treatment attempts fail in Sweden, sometimes leading to early death. READ MORE

  7. 20. Structural, thermal and thermodynamic properties of some Ln-Pd oxides and their behaviour as catalyst precursors

    Author : Martin Andersson; A.R. West; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

    Abstract : The structural, thermal and thermodynamic properties of some Ln-Pd oxides of the Ln4Pd07 type are presented. The main results are; (i) Reduction of Ln4Pd07, either ex-situ by CO or in-situ by a synthetic car exhaust gas, results in a materialwith catalytic activity for car exhaust gas clean-up reactions.
