  1. 21. Attention deficit hyperactivity disorder in adults : neuropsychological deficits and functional impairments

    Författare :Ylva Holst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall aim of the present thesis was to investigate the role of neuropsychological deficits in adult ADHD. Study I examined the psychometric properties of a new rating instrument, the Adult Executive Functioning Inventory (ADEXI), which focuses on deficits in working memory and inhibition. LÄS MER

  3. 22. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

    Författare :Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. LÄS MER

  4. 23. Cognitive strategies in simple addition and subtraction : Process models based on analyses of response latencies and retrospective verbal reports

    Författare :Maj-Lene Hedenborg; Stellan Ohlsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognition; mental arithmetic; addition; subtraction; process models; response latencies; verbal reports; errors; psykologi; Psychology;

    Sammanfattning : The purpose of this thesis is to explore cognitive processes used by children and adults when solving simple arithmetic problems, and to develop process models for describing these processes. The studies in the thesis were based mainly on analyses of response latencies and retrospective verbal reports, separately and in combination. LÄS MER

  5. 24. Quantifying neurodegeneration from medical images with machine learning and graph theory

    Författare :Gustav Mårtensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurodegeneration (or brain atrophy) is part of the pathological cascade of Alzheimer’s disease (AD) and is strongly associated with cognitive decline. In clinics, atrophy is measured through visual assessments of specific brain regions on medical images according to established rating scales. LÄS MER

  7. 25. Hybrid Solvers for the Maxwell Equations in Time-Domain

    Författare :Fredrik Edelvik; Per Lötstedt; Jan Hesthaven; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; time-domain; finite volume methods; finite element methods; hybrid solver; dispersive materials; thin wires; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : The most commonly used method for the time-domain Maxwell equations is the Finite-Difference Time-Domain method (FDTD). This is an explicit, second-order accurate method, which is used on a staggered Cartesian grid. The main drawback with the FDTD method is its inability to accurately model curved objects and small geometrical features. LÄS MER
