    Author : Stavros Aronis; Konstantinos Sagonas; Bengt Jonsson; Patrice Godefroid; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Concurrent; Parallel; Model Checking; Partial Order Reduction; Dynamic Partial Order Reduction; DPOR; Sleep Set Blocking; Source Sets; Source DPOR; Wakeup Trees; Optimal DPOR; Observers; Verification; Bounding; Exploration Tree Bounding; Testing; Erlang; Concuerror; Protocol; Chain Replication; CORFU; Computer Science; Datavetenskap;

    Abstract : Stateless model checking is a technique for testing and verifying concurrent programs, based on exploring the different ways in which operations executed by the processes of a concurrent program can be scheduled. The goal of the technique is to expose all behaviours that can be a result of scheduling non-determinism. READ MORE

  3. 3. Dynamic Train-Turnout Interaction – Mathematical Modelling, Numerical Simulation and Field Testing

    Author : Elias Kassa; Chalmers University of Technology; []
    Keywords : contact forces; Karhunen–Loève expansion; dynamic train–turnout interaction; field test; wheel–rail contact geometry; stochastic analysis; switches and crossings;

    Abstract : Two models for simulation of dynamic interaction between train and turnout are developed. The first one is derived using a commercial software for dynamics of multi-body systems. READ MORE

  4. 4. Efficient Partitioning of Dynamic Structured Grid Hierarchies

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

    Abstract : 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.

  5. 5. Dynamic principles in craniofacial surgery. Expander elements in craniofacial surgery

    Author : Fredrik Gewalli; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphocephaly; Brachycephaly; Dynamic cranioplasty; Pi-procedure; DCB; Expander elements; Distraction; Mental development; ICP; Cephalometry; Cephalic index;

    Abstract : Lannelongue & Lane described strip removal of ossified skull sutures in craniosynostosis in the 1890s. More complex osteotomies with bone grafting were developed during the 1960s. Dynamic techniques, utilizing force to direct the growing brain for skull reshaping was introduced by Jane 1978 with the p-plasty for sagittal synostosis. READ MORE
