  1. 6. Computational Modelling and Topological Analysis of the striatal microcircuitry in health and Parkinson's disease

    Författare :Ilaria Carannante; Jeanette Hellgren Kotaleski; Alexander Kozlov; Sean Hill; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Computer Science;

    Sammanfattning : The basal ganglia are evolutionary conserved nuclei located at the base of the forebrain. They are a central hub in the control of motion and their dysfunctions lead to a variety of movement related disorders, including Parkinson's disease (PD).The largest nucleus and main input stage of the basal ganglia is the striatum.

  3. 7. Efficient and Flexible Characterization of Data Locality through Native Execution Sampling

    Författare :Erik Berg; Erik Hagersten; Mark D. Hill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Data locality is central to modern computer designs. The widening gap between processor speed and memory latency has introduced the need for a deep hierarchy of caches. Thus, the performance of an application is to a large extent dependent on the amount of data locality the caches can exploit. LÄS MER

  4. 8. ATMP Process : Improved Energy Efficiency in TMP Refining Utilizing Selective Wood Disintegration and Targeted Application of Chemicals

    Författare :Dmitri Gorski; Per Engstrand; Jan Hill; Lars Johansson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ATMP; TMP; Hydrogen Peroxide; Magnesium Hydroxide; Mechanical Pre-Treatment; Fibre Characterisation; Refiner Bleaching; SC Paper; Newsprint; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : This thesis is focused on the novel wood chip refining process called AdvancedThermomechanical Pulp (ATMP) refining. ATMP consists of mechanical pretreatmentof chips in Impressafiner and Fiberizer prior to first stage refining atincreased intensity. LÄS MER

  5. 9. Wettability of modified wood

    Författare :Maziar Sedighi Moghaddam; Agne Swerin; M. Per Calessson; E.P. Magnus Wålinder; Callum Hill; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wood; dimensional stability; dynamic wettability; surface chemistry; microstructure; swelling; multicycle Wilhelmy plate method; contact angle; sorption; acetylation; furfurylation; surface modification; Kemi; Chemistry;

    Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER

  7. 10. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

    Författare :Robert Eriksson; KTH; []
    Nyckelord :Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

    Sammanfattning : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. LÄS MER
