  2. 1. Wood fibre deformation in combined shear and compression

    Author : Federica De Magistris; Anders Eriksson; Ola Dahlblom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arcan; compression; density; energy; finite element analysis; Iosipescu; Picea abies; shear; wood; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. READ MORE

  4. 2. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique

    Author : Jenny Lindau; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; displacement washing; pulp properties.; measurement technique; compression; dispersion; fibre damage; local properties; kraft pulp;

    Abstract : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. READ MORE

  5. 3. Privacy Mechanism Design Through the Lens of Information Theory : With Applications to Compression, Caching, and Semantic Communication

    Author : Amirreza Zamani; Mikael Skoglund; Tobias J. Oechtering; Parastoo Sadeghi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Privacy mechanism design; Leakage matrix; Strong privacy criterion; KL-divergence; Local approximation; Euclidean information geometry; Privacy-utility trade-off; χ2-privacy criterion; l1-privacy criterion; Common information; Functional representation lemma; Two-part construction coding; Design av sekretessmekanism; Läckagematris; Stark sekretesskriterium; KL-divergens; Lokal approximation; Euklidisk informationsgeometri; Sekretess-nyttoavvägning; χ2-sekretesskriterium; l1-sekretesskriterium; Gemensam information; Lemma för funktionell representation; Kodning med tvådelad konstruktion.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Privacy mechanism design is an important research area and is receiving increased attention in recent years. This field focuses on addressing the challenge of revealing general data that might have correlations with sensitive information, all while protecting this sensitive information against unauthorized access.

  6. 4. Metastatic spinal cord compression in prostate cancer : clinical and morphological studies

    Author : Sead Crnalic; Richard Löfvenberg; Anders Widmark; Anders Bergh; Sten Nilsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; bone metastasis; spinal cord compression; surgical treatment; survival prognosis; early diagnosis; androgen receptor; Orthopaedics; ortopedi; Pathology; patologi; Oncology; onkologi;

    Abstract : Background: Bone metastases occur in most patients with advanced hormone-refractory prostate cancer causing pain, pathologic fractures, and spinal cord compression. Few studies specifically address surgical treatment of metastatic spinal cord compression (MSCC) in prostate cancer. READ MORE

  7. 5. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard

    Author : Anton Hagman; Mikael Nygårds; Sören Östlund; Nils Hallbäck; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paperboard; Inhomogeneities; In-plane properties; Tension; Compression; Shear properties; Delamination; Hållfasthetslära; Solid Mechanics;

    Abstract : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. READ MORE
