  1. 21. Heterogeneous Materials - Diffusion, Laplace spectrum and NMR

    Författare :Matias Nordin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; perturbation; nmr; diffusion; laplace operator; spectrum; heterogeneous materials;

    Sammanfattning : Relations to the effective diffusion constant and the relaxation rate of the time-dependent diffusion coefficient for porous systems are derived from the Laplace operator spectrum. The Padé approximation is then explained in terms of the Laplace operator spectrum. LÄS MER

    Författare :Jonas Westman; Mattias Nyberg; Mats Heimdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contracts; Heterogeneous Systems; Safety; Architecture; Requirements; Specification; Elements; Compositional; IEC 61508; ISO 26262; Kontrakt; Heterogena System; Säkerhet; Arkitektur; Kravhantering; Specifiering; Element; Kompositionell; IEC 61508; ISO 26262; Machine Design; Maskinkonstruktion;

    Sammanfattning : Requirements engineering (RE) is a well-established practice that is also emphasized in safety standards such as IEC 61508 and ISO 26262. Safety standards advocate a particularly stringent RE where requirements must be structured in an hierarchical manner in accordance with the system architecture; at each level, requirements must be allocated to heterogeneous (SW, HW, mechanical, electrical, etc. LÄS MER

  4. 23. Pattern-based Programming Abstractions for Heterogeneous Parallel Computing

    Författare :August Ernstsson; Christoph Kessler; José Daniel García Sánchez; Herbert Kuchen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High‐level parallel programming; Algorithmic skeletons; Heterogeneous systems; High‐performance computing;

    Sammanfattning : Contemporary computer architectures utilize wide multi-core processors, accelerators such as GPUs, and clustering of individual computers into complex large-scale systems. These hardware trends are prevalent across computers of all sizes, from the largest supercomputers down to the smallest mobile phones. LÄS MER

  5. 24. Hardware/Software Co-Design of Heterogeneous Manycore Architectures

    Författare :Süleyman Savas; Tomas Nordström; Zain Ul-Abdin; Jari Nurmi; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardware software co-design; manycore architectures; heterogeneous manycores; processor design; parallel computing; high performance computing;

    Sammanfattning : In the era of big data, advanced sensing, and artificial intelligence, the required computation power is provided mostly by multicore and manycore architectures. However, the performance demand keeps growing. Thus the computer architectures need to continue evolving and provide higher performance. LÄS MER

  7. 25. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Författare :Ola Karlsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER
