  1. 1. Fabrication and Characterisation of Carbon Nanotube Array Thermal Interface Materials

    Författare :ANDREAS NYLANDER; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; reliability test; thermal management; thermal interface material; chemical functionalization;

    Sammanfattning : The performance of electronic devices has long been limited by thermal dissipation which will result in device failure if not handled properly. The next generation of integrated circuit (IC) devices will feature new packaging technologies like heterogeneous integration as well as 3D stacking which entails additional emphasis on the thermal management solutions employed.

  3. 2. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water

    Författare :Hua Li; Pavel Kudinov; Michele Andreani; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermal Stratification; Mixing; Pressure Suppression Pool; Containment; Thermal Hydraulic; GOTHIC; Light Water Reactor; Fysik; Physics;

    Sammanfattning : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. LÄS MER

  4. 3. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis

    Författare :Gustavo Abreu-Vieira; Jan Nedergaard; Eric Ravussin; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

    Sammanfattning : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

  5. 4. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

    Författare :Roberta Ghetti; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excitation function.; subthreshold pions; pion production; neutron cross-talk; correlation function; interferometry; intermittency; phase transition; thermal scaling; reducibility; multifragmentation; Heavy ion collisions; intermediate energy; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Ghetti;

    Sammanfattning : Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. LÄS MER

  7. 5. Fire behaviour of upholstered furniture component materials at multiple scales

    Författare :Konrad Wilkens Flecknoe-Brown; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; upholstered furniture; Polyurethane; Scaling; Experimental; Modeling; fabric;

    Sammanfattning : In this research, both experimental test methods and computer models were used to characterise the thermal decomposition processes of selected upholstered furniture component materials, namely; flexible polyurethane foam and a range of different fabric coverings. This was first done at some of the smallest, simplest levels available, and how these materials were tested and the methods chosen to investigate them, was examined. LÄS MER
