  2. 1. Methods for run time analysis of data locality

    Author : Erik Berg; Erik Hagersten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Abstract : The growing gap between processor clock speed and DRAM access time puts new demands on software and development tools. Deep memory hierarchies and high cache miss penalties in present and emerging computer systems make execution time sensitive to data locality. READ MORE

  4. 2. Efficient and Flexible Characterization of Data Locality through Native Execution Sampling

    Author : Erik Berg; Erik Hagersten; Mark D. Hill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Data locality is central to modern computer designs. The widening gap between processor speed and memory latency has introduced the need for a deep hierarchy of caches. Thus, the performance of an application is to a large extent dependent on the amount of data locality the caches can exploit. READ MORE

  5. 3. Fracture Behaviour of Wood and Fibres as Related to the Mechanical Pulping Process

    Author : Jan-Erik Berg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic emission; Engineering mechanics; Teknisk mekanik;

    Abstract : The fibre separation step in refining is crucial to energy consumption.... READ MORE

  6. 4. Wood and fibre mechanics related to the thermomechanical pulping process

    Author : Jan-Erik Berg; Per Engstrand; Per A. Gradin; Tomas Björkqvist; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic emission; Chips; Compression tests; Defibration; Disc refiners; Energy consumption; Fibre structure; Force sensors; Fracture; Impact strength; Mathematical analysis; Moisture content; Picea abies; Refining; Stiffness degradation; Strains; Temperature; Thermomechanical pulping; Velocity; Chemical engineering; Kemiteknik;

    Abstract : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. READ MORE

  7. 5. Everyday Mobility and Travel Activities during the first years of Retirement

    Author : Jessica Berg; Jan-Erik Hagberg; Marianne Abramsson; Lena Levin; Kerstin Westin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ageing; retirement; mobility; travel activities; place; time-geography; interviews; travel diaries; qualitative longitudinal analysis; åldrande; pensionering; mobilitet; resande; aktivitet; plats; tidsgeografi; intervjuer; resdagböcker; kvalitativ longitudinell analys; 11 Road: Personal transport;

    Abstract : Mobility is central to living an independent life, to participating in society, and  to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways.
