  2. 1. Exposure assessment for the prevention of musculoskeletal disorders

    Author : Istvan Balogh; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yrkesmedicin; industrial medicine; Occupational health; heart rate; interindividual variation; index; arbetsmiljömedicin; job strain; Questionnaire; mechanical exposure;

    Abstract : Work-related musculoskeletal disorders of shoulder/neck are a major and increasing problem. Beside the pain, they involve high cost for the employer and society. The total expenditure for the musculoskeletal disorders of the neck and upper limb have been estimated to 0.5-2. READ MORE

  4. 2. Economic perspectives on the obesity epidemic

    Author : Åsa Ljungvall; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Obesity; body-mass index; BMI; waist circumference; inequality; socioeconomic inequalities; concentration index; socioeconomic disparities; time trends; economic freedom; misreporting; misclassification;

    Abstract : This thesis takes its starting point in the large spread and rise in obesity prevalence that have been observed around the world, making obesity an increasing public health concern. The thesis consists of an introductory chapter, which justifies the study of obesity from economic perspectives and puts the subsequent studies in context, and four studies that address obesity from different economic perspectives.

  5. 3. Voronoi-Based Coding

    Author : Erik Agrell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voronoi diagram; linear block code; Gaussian channel; neighbor descent; nearest neighbor search algorithm; computational geometry; asymptotic theory; source coding; lattice; vector quantization; soft-decision decoding; index assignment; channel coding; complexity;

    Abstract : The performance of a digital communication system can generally be improved by increasing the number of variables being jointly coded. In this sense, it is desirable to have, e.g., higher-dimensional quantizers, longer channel codes, and more users in a multiple-access system. READ MORE

  6. 4. Improving capability assessments for disaster risk management

    Author : Hanna Lindbom; Avdelningen för Riskhantering och Samhällssäkerhet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; disaster risk management DRM ; societal safety; capability assessment; response; decision-making; control;

    Abstract : There is an urgent need for society to find more effective ways to reduce the impact of disastrous events. One way is to proactively increase actors’ response capability. Capability assessments play an essential role in these disaster risk management efforts. READ MORE

  7. 5. On Soft Decoding and Robust Vector Quantization

    Author : Mikael Skoglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech and image coding; intersymbol interference; Rayleigh fading; soft decoding; CDMA; index assignment; Hadamard transform; channel optimized VQ; robust VQ; combined source-channel coding; vector quantization VQ ; noisy channels;

    Abstract : This thesis considers vector quantization for noisy channels. Vector quantization (VQ) is an important technique for block-based source coding, with applications in, e.g., speech and image coding. READ MORE
