  2. 1. Models and Methods for Development of DSP Applications on Manycore Processors

    Author : Jerker Bengtsson; Bertil Svensson; Shuvra S. Bhattacharyya; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parallel processing; manycore processors; high-performance digital signal processing; dataflow; concurrent models of computation; parallel code mapping; parallel machine model; dynamic performance analysis; Computer engineering; Datorteknik;

    Abstract : Advanced digital signal processing systems require specialized high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. READ MORE

  4. 2. Genetic Traits Beneficial for Xylose Utilization by Recombinant Saccharomyces cerevisiae

    Author : Oskar Bengtsson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; metabolic engineering; fermentation; xylose; ethanol; promoter; xylose reductase; cofactor; validation; transcriptome;

    Abstract : Saccharomyces cerevisiae ferments hexoses in lignocellulosic hydrolysates under anaerobic conditions with high rates and ethanol yields. However, S. cerevisiae is naturally unable to utilize the pentose fraction of the hydrolysates. Xylose is the most abundant pentose sugar, and although recombinant S. READ MORE

  5. 3. Robust self-localization of mobile robots in dynamic environments using scan matching algorithms

    Author : Ola Bengtsson; Christian Schlegel; Chalmers tekniska högskola Göteborg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile robot; Self-localization; Scan matching algorithm; Changed environments; Dynamic environments; o-variance matrix; Kalman filter; Signal processing; Signalbehandling;

    Abstract : The most fundamental task for any mobile robot is to perform self-localization in the world in which it is currently active, i.e. determine its position relative its world. Encoders that count wheel rotations are often used, which can be turned into relative position estimates by mean of integration. READ MORE

  6. 4. On the etiology and pathogenesis of systemic lupus erythematosus with special reference to environmental factors

    Author : Anders Bengtsson; Reumatologi och molekylär skelettbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Skeleton; Risk factors; Human parvovirus B19; Immune complex; Disease activity; Interferon-alpha; SLE; Retrovirus;

    Abstract : Systemic lupus erythematosus (SLE) is a complex autoimmune disease in which environmental factors interact with genetic factors in the development of the disease process and evolution of clinical manifestations. In this thesis both exogenous factors and host factors were investigated, as well as important immunopathological aspects including involvement of immune complex (IC), the complement system and interferon-alpha (IFN-α).

  7. 5. Applications of Bayesian Econometrics to Financial Economics

    Author : Christoffer Bengtsson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic systems; economic theory; econometrics; Economics; systemic risk; stochastic volatility; jump-diffusion; shrinkage; covariance matrix estimation; estimation risk; portfolio selection; mean-variance optimization; Markov chain Monte Carlo; Bayesian econometrics; ekonomisk politik; ekonomiska system; ekonomisk teori; ekonometri; Nationalekonomi; economic policy;

    Abstract : This PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. READ MORE
