  1. 1. Numerical Solution Methods in Stochastic Chemical Kinetics

    Författare :Stefan Engblom; Per Lötstedt; Wilhelm Huisinga; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic models; chemical master equation; mesoscopic kinetics; Markov property; jump process; moment closure problem; spectral-Galerkin method; high dimensional problem; hybrid methods; time-parallel; homogenization; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : This study is concerned with the numerical solution of certain stochastic models of chemical reactions. Such descriptions have been shown to be useful tools when studying biochemical processes inside living cells where classical deterministic rate equations fail to reproduce actual behavior. LÄS MER

  2. 2. Scheduling techniques to improve the worst-case execution time of real-time parallel applications on heterogeneous platforms

    Författare :Petros Voudouris; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel applications; global; work-conserving; federated; heterogeneous multiprocessors; response time; Hard real-time systems; unrelated model; DAG; makespan;

    Sammanfattning : The key to providing high performance and energy-efficient execution for hard real-time applications is the time predictable and efficient usage of heterogeneous multiprocessors. However, schedulability analysis of parallel applications executed on unrelated heterogeneous multiprocessors is challenging and has not been investigated adequately by earlier works. LÄS MER

  3. 3. Towards an Early Holocene Tephrochronology for the Faroe Islands: Methodology and first results

    Författare :Ewa Lind; Stefan Wastegård; Margareta Hansson; Britta Sannel; Jane Boygle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quarternary Geology; kvartärgeologi;

    Sammanfattning : The uncertainties regarding future climate change have put considerable notice to the climate variability following the Late Glacial-Holocene transition (ca. 13-9 ka BP) in the North Atlantic region as well as the forcing mechanisms behind climate changes. LÄS MER

  4. 4. Parallel computing in model-based process engineering

    Författare :Niklas Andersson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parameter estimation; Optimisation; Parameter selection; Model-based engineering;

    Sammanfattning : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. LÄS MER

  5. 5. Exploring the relationship between alcohol use disorders and internalising disorders in longitudinal cohorts of adolescents

    Författare :Lina Homman; Francis O'Neill; UK Queen's University Belfast; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alcohol use disorder; Mental health; Children; Youth; Comorbidity; Longitudinal analysis;

    Sammanfattning : The literature supports a relationship between alcohol use disorders and internalising disorders, but how they relate to each other is unclear. Both disorders, as well as their comorbidity increase in adolescence, making adolescence of particular interest. LÄS MER
