  1. 6. Efficient Partitioning of Dynamic Structured Grid Hierarchies

    Författare :Johan Steensland; Michael Thuné; Jarmo Rantakokko; Charles Norton; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scientific computing; partitioning; structured grids; adaptive mesh refinement; dynamic load balancing; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.

  3. 7. SME Performance and Its Relationship to Innovation

    Författare :Adli Abouzeedan; Magnus Klofsten; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SME performance; performance evaluation; firm efficiency; SIV model; innovation capital; system capital; open capital; business models; Business and economics; Ekonomi;

    Sammanfattning : Current SME performance models suffer from a number of disadvantages. The models use intensively a business ratio approach, they look at SMEs as a homogenous group, they consider firms to be closed systems, they do not directly incorporate the impact of an enterprise’s innovation activities, and finally they are complex and rely on sophisticated statistical refining methods making them unpractical to use by SME managers.

  4. 8. Clinical and experimental studies on the diaphragm during physiological and pathophysio-logical conditions

    Författare :Antonella Lo Mauro; Peter Frykholm; Andrea Aliverti; Anders Larsson; Stephen Edward Rees; Uppsala universitet; []
    Nyckelord :diaphragm; animal model; phrenic nerve injury; pregnancy; lung transplan- tation; stereotactic body radiation therapy; anesthesia; Clinical Physiology; Klinisk fysiologi;

    Sammanfattning : The diaphragm is the most important respiratory muscle. It separates the thorax from the abdomen and it is innervated by phrenic nerve. LÄS MER

  5. 9. A Constructive Approach to the Interaction between Risk and Logistics - A Study of Total Offers in the Aerospace Industry

    Författare :Jenny Svanberg; Förpackningslogistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Air transport technology; Constructive Approach; Total Offer; Aircraft Industry; Uncertainty; Risk Analysis; Logistics; Inbound Logistics; Lufttransportteknik;

    Sammanfattning : Total offers have become increasingly common in the aircraft industry during recent years. The total offers bring on challenges as well as possibilities for the providers of engine maintenance. The possibilities, increased profitability and efficiency, are depending on how the organisation copes with the challenges. LÄS MER

  7. 10. A generic security evaluation method for open distributed systems

    Författare :Ann Frisinger; KTH; []
    Nyckelord :information security; security evaluation; risk analysis; method; ipen distributed system; virtual system; networked education; X-ify; NED-ify;

    Sammanfattning : Security is an important attribute of any informationsystem. Whether your business is small or large you have to beable to set the desired security levels for your system. Anon-decided or non-fulfilled security level target can easilyend up in unplanned costs. LÄS MER
