  1. 16. Wireless Communication with Medical Implants: Antennas and Propagation

    Detta är en avhandling från Department of Electroscience, Lund University

    Författare :Anders J Johansson; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical implant communication; electromagnetic propagation; biomedical telemetry; antennas in matter; MICS; Electronics; Elektronik;

    Sammanfattning : With the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. LÄS MER

  2. 17. MEASUREMENT OF PARTICULATES EMITTED FROM SGDI ENGINES

    Detta är en avhandling från Department of Electroscience, Lund University

    Författare :Anders Johansson; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis discusses particulate emissions from spray guided, gasoline, direct-injected (GDI) engines. The aim was to measure solid particulates without the influence of volatiles. Therefore, two sampling systems were developed for sampling either low or high particulate content. LÄS MER

  3. 18. Offentlig kultur i omvandling? : Om prestationsfinansiering och konkurrensutsättning av offentlig serviceverksamhet

    Detta är en avhandling från Örebro : Örebro universitetsbibliotek

    Författare :Anders Johansson; Örebro universitet.; [2003]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Statsvetenskap; Institutionalised standard; Institutional organisation theory; Cultural theory; Public culture; Organisation culture; Financing by results; Exposure to competition; Legitimacy; statskunskap; SOCIAL SCIENCES Social sciences Political science; SAMHÄLLSVETENSKAP Socialvetenskap Statsvetenskap; Political Science; Statskunskap;

    Sammanfattning : The aim of this study is to examine whether introducing organisational ideas, first used within the private trade and industry sector, in public affairs will have any effect on public culture. In focus for this study are financing by results and exposure to competition, which are standards institutionalised in the environment of the public organisations. LÄS MER

  4. 19. Out-of-Round Railway Wheels - Causes and Consequences An Investigation Including Field Tests, Out-of-Roundness Measurements and Numerical Simulations

    Detta är en avhandling från Örebro : Örebro universitetsbibliotek

    Författare :Anders Johansson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygonalization; wheel flat; full-scale measurements; wear modelling; impact load detector; railway wheel out-of-roundness; wheel removal criterion; dynamic train-track interaction; corrugation;

    Sammanfattning : Causes and consequences of out-of-round railway wheels are investigated through literature studies, full-scale field experiments, out-of-roundness measurements, and numerical simulations. Both defects around the complete wheel circumference (e.g. polygonal wheels with wavelengths up to one wheel circumference) and local defects (e. LÄS MER
