  1. 16. On Enhancement and Quality Assessment of Audio and Video in Communication Systems

    Författare :Andreas Rossholm; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; video quality assessment; video quality metric; multi-linear regression; artificial neural network; support vector machine; quality predictor; machine learning; temporal scaling; spatial scaling; video compression; deblocking filter; noise cancelling; synchronization; audio delay; video delay; GSM interference signal; noise cancellation; notch filtering;

    Sammanfattning : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. LÄS MER

  3. 17. Physical activity among patients with cardiovascular disease : a predictor of hospital care utilisation and mortality in clinical work

    Författare :Amanda Ek; Örjan Ekblom; Lena Kallings; Mats Börjesson; Joep Perk; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; Physical exercise; Sedentary behaviour; Physical activity; Survival; Mortality; Hospitalisation; Cardiology Service; Guideline adherence; Medicin Teknik; Medicine Technology;

    Sammanfattning : Guidelines highlight the importance of physical activity (PA) in secondary prevention of cardiovascular disease (CVD) within the healthcare sector. Previous studies have mainly focused on the effects of PA at moderate-vigorous intensity performed within exercise-based cardiac rehabilitation (CR). LÄS MER

  4. 18. Functional Capacity as a Predictor of Everyday Functioning in Patients with Schizophrenia

    Författare :Anna-Karin Olsson; Lars Helldin; Fredrik Hjärthag; Arto Hiltunen; Torill Ueland; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Schizophrenia; Functional capacity; Everyday functioning; Self-awareness; Assessment instrument; Psykologi; Psychology;

    Sammanfattning : The overall purpose of this thesis is to increase knowledge of the concept of functional capacity and how it is related to everyday functioning for adult patients with schizophrenia spectrum disorders. The thesis comprises three papers (Papers I-III) based on empirical data from a clinically representative sample of outpatients. LÄS MER

  5. 19. Regression on high-dimensional predictor space : with application in chemometrics and microarray data

    Författare :Arief Gusnanto; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Regression; near-infrared calibration; microarray; mixed model; logistic regression; random effects; variable selection; differential expression; mixture distribution;

    Sammanfattning : This thesis focuses on regression methodology for prediction and classification in situations where there are many predictors but limited number of observations. This situation is common in chemometrics and microarray data. LÄS MER

  7. 20. Event Prediction and Bootstrap in Time Series

    Författare :Anders Svensson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; bootstrap control.; statistical bootstrap; catastrophe; level-crossings; ARMAX process; Optimal alarm system; time series; optimal event predictor; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. LÄS MER
