  2. 1. Fully Nonlinear Unsteady Three-Dimensional Boundary Element Method for Force Predictions on a Restrained Hull in Waves

    Author : Martin Kjellberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time-dependent; BEM; nested domain; fully nonlinear; free-surface;

    Abstract : There is a need from both academia and industry for more accurate and efficient methods for predicting the behavior of ships in a seaway. A large variety of methods with varying level of sophistication and accuracy already exists today. READ MORE

  4. 2. Laying Tiles Ornamentally: An approach to structuring container traversals

    Author : Nikita Frolov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zippers; cache hierarchies; loop tiling; embedded domain-specific languages; parallelism; algebraic ornaments;

    Abstract : Having hardware more capable of parallel execution means that more program scheduling decisions have to be taken to utilize that hardware efficiently. To this end, compilers implement coarse-grained loop transformations in addition to traditionally used fine-grained instruction reordering. READ MORE

  5. 3. On computational homogenization of transient poromechanics problems

    Author : Fang Su; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; homogenization; porous media; Representative Volume Element RVE ; consolidation; FE2; multiscale modeling;

    Abstract : Many engineering materials are, in fact, microscopically heterogeneous. This is true fornatural materials, such as timber and clay, as well as manmade materials, like metal alloysand concrete. READ MORE

  6. 4. Adaptive human-agent dialogues for reasoning about health

    Author : Jayalakshmi Baskar; Helena Lindgren; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this research is to develop new theories, methods and technology, which enables adaptive and personalised dialogues between a human and a software agent, to handle everyday queries about health that are perceived as meaningful and useful to the human. Some of the challenges to build such human-agent dialogue system are the following. READ MORE

  7. 5. Procedures in Adaptive Finite Element Analysis

    Author : Peter Möller; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present work is concerned with topics related to some adaptive methods for the approximate solution of differential equations. Emphasis is on the finite element method for second order elliptic equations, where we use either p-refinement or remeshing with an advancing front mesh generator in order to improve approximate solutions.
