  2. 1. Radio Frequency InGaAs MOSFETs

    Author : Navya Sri Garigapati; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V compound semiconductor; InGaAs MOSFET; Quantum well; Nanowire; Radio Frequency; Band structure calculation; k.p calculations; Strain engineering; ballistic electron transport; S-parameters;

    Abstract : III-V-based Indium gallium arsenide is a promising channel material for high-frequency applications due to its superior electron mobility property. In this thesis, InGaAs/InP heterostructure radio frequency MOSFETs are designed, fabricated, and characterized. READ MORE

  4. 2. Mental ill-health in childbearing women : Markers and risk factors

    Author : Anne-Marie Wangel; Malmö högskola; []
    Keywords : markers; mental ill-health; pregnancy; psychiatric inpatient care; risk factors;

    Abstract : The awareness of mental health problems in women of reproductive age has increased worldwide in the recent decades. Much research has focused on symptoms of depression in women and the risk of postpartum depression, as a factor of attachment problems and adverse health effects on the newborn and growing child.

  5. 3. Trapezius muscle fatigue and electromyographic frequency analysis

    Author : Tommy Öberg; Linköpings universitet; []
    Keywords : EMG; Spectrum; Frequency; Fatigue; Trapezius; Myalgia; MEDICINE; MEDICIN;

    Abstract : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. READ MORE

  6. 4. Realism in metacognitive judgments : Effects of social factors

    Author : Marcus Johansson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social factors; metacognitive judgments; frequency judgments; Realism; confidence judgments; Psychology; Psykologi;

    Abstract : Theoretical accounts and models of calibration typically explain the degree of realism (validity) in confidence and frequency judgments in terms of different cognitive and methodological factors. The present thesis demonstrates that also social factors are of importance for the degree of realism in these types of metacognitive judgments. READ MORE

  7. 5. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

    Author : Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

    Abstract : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. READ MORE
