  1. 1. Nonlinear Characterisation and Modelling of Microwave Semiconductor Devices

    Författare :Mattias Thorsell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; noise modelling; nonlinear measurement; active load-pull; noise measurement; thermal characterisation; AlGaN GaN HEMT; nonlinear modelling;

    Sammanfattning : There is an increasing need for more accurate models taking into account the nonlinearities and memory effects of microwave transistors. The memory effects are especially important for transistor technologies suffering from relatively large low frequency dispersion, such as GaN baed HEMTs. LÄS MER

  3. 2. Supporting lifestories through activity recognition and digital reminiscence

    Författare :Basel Kikhia; Chris Nugent; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : This licentiate thesis discusses how lifelogging technologies can be used to build digital reminiscence systems. Lifelogging is a recent pervasive computing trend where different aspects of someone’s life are captured digitally. LÄS MER

  4. 3. Model Error Compensation in ODE and DAE Estimators : with Automotive Engine Applications

    Författare :Erik Höckerdal; Erik Frisk; James Peyton-Jones; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Sammanfattning : Control and diagnosis of complex systems demand accurate information of the system state to enable efficient control and to detect system malfunction. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. LÄS MER

  5. 4. Tinnitus in Patients with Sensorineural Hearing Loss : Management, Quality of Life and Treatment Strategies

    Författare :Reza Zarenoe; Torbjörn Ledin; Gerhard Andersson; Gunnel Backenroth; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Approximately 15% of Swedish people experience tinnitus, but only 2.4% experience severe problems. Treatment modalities for tinnitus vary, but the most common treatment is counseling. LÄS MER
