  1. 6. On Observation of and Interaction in Open Distributed Systems

    Författare :Jens-Olof Lindh; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherence; interaction; temporal interval; relativity; uncertainty;

    Sammanfattning : The thesis presents the results of research in computer science, as applied within a series of industrial projects. All of these projects have been part of an iterative and adaptive development process, from which we can draw conclusions in three different aspects. LÄS MER

  3. 7. Picture Viewing and Picture Description: Two Windows on the Mind

    Författare :Jana Holsanova; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; discourse hierarchy; picture description; vision; picture viewing; information flow; discourse segmentation; discourse analysis; coherence; semantics; spatial and temporal relations; cognitive science; linguistics; cognitive linguistics; psycholinguistics; speech; cognition; multimodal communication; mental processes; eye movement protocol; focus of attention; spoken language protocol; information processing; scene perception; areas of interest;

    Sammanfattning : In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. LÄS MER

  4. 8. Methods for Creating and Exploiting Data Locality

    Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; David Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data locality; temporal locality; spatial locality; prefetching; cache; cache behavior; cache coherence; snooping protocols; partial differential equation; shared-memory multiprocessor; chip multiprocessor; simulation; Computer engineering; Datorteknik;

    Sammanfattning : The gap between processor speed and memory latency has led to the use of caches in the memory systems of modern computers. Programs must use the caches efficiently and exploit data locality for maximum performance. LÄS MER

  5. 9. Permeable islands : A contrastive study of Swedish and English adjunct clause extractions

    Författare :Christiane Müller; Svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; acceptability judgments; adjunct islands; coherence; filler-gap dependencies; finiteness; Swedish; syntax;

    Sammanfattning : This dissertation is concerned with extraction from adjunct clauses in Swedish and English. The topic is of interest because adjunct clauses are traditionally considered to be strong islands for extraction across languages (the Adjunct Condition). LÄS MER

  7. 10. Spectral-element simulations of turbulent wall-bounded flows including transition and separation

    Författare :Johan Malm; Dan Henningson; Philipp Schlatter; Suad Jakirlic; KTH; []
    Nyckelord :spectral-element method; direct numerical simulation DNS ; large-eddy simulation LES ; turbulence; transition; over-integration; three-dimensional separation; massively parallel simulations; proper orthogonal decomposition POD ; Koopman modes; vorticity stretching; coherence; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    Sammanfattning : The spectral-element method (SEM) is used to study wall-bounded turbulent flowsin moderately complex geometries. The first part of the thesis is devoted to simulations of canonical flow cases, such as temporal K-type transitionand turbulent channel flow, to investigate general resolution requirements and computational efficiency of the numerical code nek5000.
