  1. 11. Off-line Foveated Compression and Scene Perception: An Eye-Tracking Approach

    Författare :Marcus Nyström; Humanistlaboratoriet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gaze prediction; off-line foveation; scene perception; eye-tracking; compression;

    Sammanfattning : With the continued growth of digital services offering storage and communication of pictorial information, the need to efficiently represent this information has become increasingly important, both from an information theoretic and a perceptual point of view. There has been a recent interest to design systems for efficient representation and compression of image and video data that take the features of the human visual system into account. LÄS MER

  3. 12. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders

    Författare :Josefina Nordström; Göran Alderborn; Maria Strömme; Katharina Picker-Freyer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compaction; compression; granules; Kawakita; mechanical properties; particles; PAT; pharmaceutical powders; tablets; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. LÄS MER

  4. 13. A way of reducing the energy demand in TMP by shear/compression deformation

    Författare :Silvia Viforr; Lars Wågberg; Lennart Salmén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear; compression; pulses; wood chips; coarse fibre; mechanical pulping; wood cells; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : One of the major cost factors in mechanical pulp production is the electrical energy input. Much of the research in this field has therefore been devoted to an understanding of the mechanisms in the refining process and, consequently, to find ways of reducing the electrical energy consumption.

  5. 14. Lossy and Lossless Compression Techniques to Improve the Utilization of Memory Bandwidth and Capacity

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

    Sammanfattning : Main memory is a critical resource in modern computer systems and is in increasing demand. An increasing number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates and greater memory capacity. LÄS MER

  7. 15. On sparse voxel DAGs and memory efficient compression of surface attributes for real-time scenarios

    Författare :Dan Dolonius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; directed acyclic graph; surface properties; neural networks; voxel; compression; spherical gaussians; light field; octree; filtering; geometry;

    Sammanfattning : The general shape of a 3D object can expeditiously be represented as, e.g., triangles or voxels, while smaller-scale features usually are parameterized over the surface of the object. LÄS MER
