  1. 1. Design of Energy-Efficient High-Performance ASIP-DSP Platforms

    Författare :Andréas Karlsson; Dake Liu; Andreas Ehliar; Jarmo Takala; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.

  3. 2. Microsimulation modelling of prostate cancer screening in Sweden

    Författare :Andreas Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Evidence-based health policy may require modelling of different interventions. The choice of model complexity is a trade-off, where simpler models may be easier to describe and calibrate, while complex models may better represent the disease dynamics and lead to more valid predictions.

  4. 3. Nonlinear Quantile Regression for Longitudinal Data

    Författare :Andreas Karlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bootstrap; dependent errors; median regression; Monte Carlo simulation; panel data; repeated measures; Statistics; Statistik; Biostatistics; Biostatistik;

    Sammanfattning : The overall objective of the two papers in this thesis is to examine the properties of the weighted nonlinear quantile regression estimator for the analysis of longitudinal data. To this end, the question of which weights to be used, the bias of the estimator and the possibility to calculate confidence intervals has to be examined. LÄS MER

  5. 4. Behovsstyrd ventilation i lokalbyggnader-Innebörd och strömningstekniska konsekvenser

    Författare :Andreas Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duct systems; energy efficiency flow mechanics; DCV; energy; pressure; ventilation; control-on-demand; demand controlled ventilation;

    Sammanfattning : In todays society energy efficiency and energy savings are becoming increasingly important. The building sector represents a major part of Swedens total use of energy. Furthermore, ventilation constitutes the single largest factor in the energy balance of buildings. LÄS MER

  7. 5. Characterization and Engineering of Protein-Protein Interactions Involving PDZ Domains

    Författare :Andreas Karlsson; Per Jemth; Daniel Otzen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered protein regions; PDZ domain; binding kinetics; protein engineering; interaction mechanism; specificity; PDZbody; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : The work presented in this thesis has contributed with knowledge to several aspects of protein-protein interaction involving PDZ domains. A substantial amount of our proteome contains regions that are intrinsically disordered but fold upon ligand interaction. LÄS MER
