  1. 6. Management of 1-D sequence data - from discrete to continuous

    Författare :Ling Lin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Data over ordered domains such as time or linear positions are termed sequence data. Sequence data require special treatments which are not provided by traditional DBMSs. Modelling sequence data in traditional (relational) database systems often results in awkward query expressions and bad performance. LÄS MER

  3. 7. Automatic and Explicit Parallelization Approaches for Mathematical Simulation Models

    Författare :Mahder Gebremedhin; Peter Fritzson; Francesco Casella; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation; Modelling; Parallel Programming; Mutli-core; Modelcia; OpenModelica; ParModelica;

    Sammanfattning : The move from single core and processor systems to multi-core and many-processors systemscomes with the requirement of implementing computations in a way that can utilizethese multiple units eciently. This task of writing ecient multi-threaded algorithmswill not be possible with out improving programming languages and compilers to providethe mechanisms to do so. LÄS MER

  4. 8. On conceptual modelling of mode switching systems

    Författare :Ulf Söderman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with fundamental issues underlying the systematic construction of behaviour models of physical systems, especially man made engineering systems. These issues are important for the design and development of effective computer aided modelling systems providing high-level support for the difficult task of modelling. LÄS MER

  5. 9. Resampling Evaluation of Signal Detection and Classification : With Special Reference to Breast Cancer, Computer-Aided Detection and the Free-Response Approach

    Författare :Anna Bornefalk Hermansson; Rolf Larsson; Ulf Olsson; Dankmar Böhning; Uppsala universitet; []
    Nyckelord :Statistics; breast cancer; trend modelling; FROC; confidence intervals; threshold independence; bootstrap; kernel density estimation; mammography; computer-aided detection; Statistik;

    Sammanfattning : The first part of this thesis is concerned with trend modelling of breast cancer mortality rates. By using an age-period-cohort model, the relative contributions of period and cohort effects are evaluated once the unquestionable existence of the age effect is controlled for. LÄS MER

  7. 10. Computational modelling of rail manufacturing

    Författare :Torbjörn Lindbäck; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : The thesis deals with simulation of rail manufacturing. During the manufacturing process residual stresses arise in the rail, primarily due to cooling and straightening. These stresses can affect product performance, for example fatigue characteristics. Therefore it would be desirable to be able to predict these in an efficient way. LÄS MER
