  1. 11. Pulp washing - Determining local properties using a new measurement technique

    Författare :Jenny Lindau; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local properties; displacement washing; washing; measurement technique; pulp washing;

    Sammanfattning : 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 save a substantial amount of energy, reduce costs by reducing the need for make-up chemicals and improve the bleaching process. There are many discrepancies in the literature, however, as to how different parameters influence washing efficiency. LÄS MER

  3. 12. A Multidimensional Filtering Framework with Applications to Local Structure Analysis and Image Enhancement

    Författare :Björn Svensson; Hans Knutsson; Mats Andersson; Oleg Burdakov; Abhir Bhalerao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical image science; multidimensional filtering; image enhancement; image registration; image segmentation; filter networks; graphics processing units GPU ; Medical engineering; Medicinsk teknik;

    Sammanfattning : Filtering is a fundamental operation in image science in general and in medical image science in particular. The most central applications are image enhancement, registration, segmentation and feature extraction. LÄS MER

  4. 13. Integral and local AC-susceptibility : instrumentation and applications

    Författare :Valter Ström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : This thesis presents my mostly unpublished experimental work related to two major contributions with the design of: A high precision and versatile bulk average(or integral) AC-susceptometer and its application to investigations of exchange anisotropy in Co multilayers. A novel Local Susceptibility measurement technique exploiting the narrow gap in inductive ring-heads in magnetic recording technology. LÄS MER

  5. 14. Measurements for winter road maintenance

    Författare :Mats Riehm; Per-Erik Jansson; Eros Pasero; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; winter road maintenance; sensors; infrared thermometry; energy efficiency; road salt;

    Sammanfattning : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl). LÄS MER

  7. 15. A systems approach to ice loads on concrete dams

    Författare :Rikard Hellgren; Richard Malm; Anders Ansell; Erik Nordström; Pierre Legér; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice loads; Ice pressure; Dam safety; Concrete dams; Cold regions; Monitoring; Measurements; Concrete Structures; Betongbyggnad;

    Sammanfattning : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. LÄS MER
