  1. 1. Statistical Compression Cache Designs

    Författare :Angelos Arelakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cache; Floating-point compression; Data Compression; Huffman Coding; Statistical Compression; Value Locality; Memory; Hybrid Compression;

    Sammanfattning : On-chip caches are essential as they bridge the growing speed-gap between off-chip memory and processors. To this end, processing cores are sacrificed for more cache space in the chip's real estate, possibly affecting the cache access time and power dissipation. LÄS MER

  2. 2. Reducing Memory Traffic with Approximate Compression

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

    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. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure

    Författare :Ann-Sofie Persson; Göran Frenning; Göran Alderborn; Marie Wahlgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Discrete Element Method; Granule; Flow; Angle of Repose; Discharge Rate; Shear; Rolling friction; Compression; Elastic deformation; Microstructure; Degree of compression; Tensile strength; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. LÄS MER

  4. 4. Confined Compression of Single Particles : Development of a Novel Triaxial Testing Instrument and Particle-Scale Modelling

    Författare :Henrik Jonsson; Göran Frenning; Göran Alderborn; Abderrahim Michrafy; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Powder compaction; Compression; Single particle; Particle mechanics; Powder mechanics; Confined conditions; Triaxial; Apparatus design; Modelling; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : When predicting the performance of a powder compaction process, assessing the behaviour of the particles comprising the powder bed is of central relevance. Currently, however, no experimental methods are available for mimicking the multiaxial loading conditions imposed on the individual particles in a powder bed during compaction, and such analyses are therefore usually performed in silico.

  5. 5. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties

    Författare :Maryam Tofiq; Göran Alderborn; Ann-Sofie Persson; Josefina Nordström; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dry granulation; Powder compression; Compression parameters; Granule composition; Granule structure; Granule strength; Granule fragmentation; Granule deformation; Tablet tensile strength; Loss of tabletability;

    Sammanfattning : Dry granulation (DG) is often utilized as an intermediate process during tablet manufacturing, for improving flow characteristics of the powder blend and/or reducing segregation issues related to the active pharmaceutical ingredient (API). The resulting granules exhibit typically irregular shapes with rough surfaces and their mechanical properties are related to the feeding powder and the process parameters used during the DG. LÄS MER
