  1. 1. “Count on me!” Mathematical development, developmental dyscalculia and computer-based intervention

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Linda Olsson; Linköpings universitet.; Linköpings universitet.; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematical development; symbolic number processing; Approximate number system; developmental dyscalculia; computer-based intervention; matematisk utveckling; symboliskt nummerprocessande; Approximativa nummersystemet; dyskalkyli; datorbaserad intervention;

    Sammanfattning : A “sense” of number can be found across species, yet only humans supplement it with exact and symbolic number, such as number words and digits. However, what abilities leads to successful or unsuccessful arithmetic proficiency is still debated. LÄS MER

  2. 2. Reducing Memory Traffic with Approximate Compression

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Albin Eldstål-Ahrens; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory Systems; Memory Compression; Compression; Computer Architecture; Approximate Computing; Lossy Compression;

    Sammanfattning : Memory bandwidth is a critical resource in modern systems and has an increasing demand. The large number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates. In addition, new emerging data-intensive applications further increase memory traffic. LÄS MER

  3. 3. Applied estimation of piecewise constant parameters

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Soheil Salehpour; Luleå tekniska universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : A time-varying linear system is a realistic description of many industrial processes, and nonlinear behavior can then also be accounted for. Then, we can consider a linear system with time-varying parameters as the model uncertainty, \emph{e.g.} an AR(X) model or an affine input-output approximation. LÄS MER

  4. 4. Fixed-Parameter Algorithms for Optimal Convex Partitions and Other Results

    Detta är en avhandling från Department of Computer Science, Lund University

    Författare :Magdalene Grantson Borgelt; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control; Datalogi; numerical analysis; Convex Partition; Computer science; Triangulation; kontroll; system; numerisk analys; systems; Fixed-Parameter Algorithm; Spanning Tree;

    Sammanfattning : In this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. LÄS MER

  5. 5. Constructing Evolutionary Trees - Algorithms and Complexity

    Detta är en avhandling från Department of Computer Science, Lund University

    Författare :Anna Östlin; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Maximum homeomorphic subtrees; Consensus trees; Experiment model; Evolutionary trees; Complexity; Computational biology; Algorithms; Data structures; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Biology; Biologi;

    Sammanfattning : In this thesis three general problems concerning construction of evolutionary trees are considered. Algorithms for the problems are presented and the complexity of the problems is investigated. The thesis consists of three corresponding parts. The first part is devoted to the problem of constructing evolutionary trees in the experiment model. LÄS MER
