  2. 1. The Compression/Absorption Heat Pump Cycle - System Simulations

    Author : Lena Åhlby; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compression; refrigerant mixture; absorption; NH3 H2O; NH3 H2O-LiBr;

    Abstract : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. READ MORE

  4. 2. lntramuscular pressure in the lower leg - Studies on chronic exertional compartment syndrome and effects of external compression

    Author : Sophia Lindorsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intramuscular pressure; external compression; compartment syndrome; chronic exertional compartment syndrome; fasciotomy;

    Abstract : This thesis on intramuscular pressure (IMP) in the lower leg is concerned with two topics. The first of these is external compression; more specifically, the effect of compression stockings (CS). There are conflicting data on how compression garments such as CS affect IMP and muscle function during activity. READ MORE

  5. 3. Precalendering and its interaction with other unit processes in the manufacturing of woodfree paper and board

    Author : Olof Steffner; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calendering; soft-nip calendering; wet press; compression; deformation; coating; water box;

    Abstract : ABSTRACTDuring calendering, which is done in order to improve its printing properties, the paper is compressed in one or more roll nips. Paper is a viscoelastic material and this will influence its performance during calendering. READ MORE

  6. 4. On Compression and Coordination in Networks

    Author : Ricardo Blasco-Serrano; Mikael Skoglund; Ragnar Thobaben; Luc Vandendorpe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The current trends in communications suggest that the transfer of information between machines will soon predominate over the traditional human-oriented exchange. The new applications in machine-to-machine communications demand for a new type of networks that are much larger and, especially, much denser. READ MORE

  7. 5. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber

    Author : Shaheda T. Akter; Thomas K. Bader; Erik Serrano; Jan Oscarsson; Reinhard Brandner; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shear; biaxial testing; stress combination; RT-plane; moisture influence; rolling shear creep; digital image correlation; strain field; CLT connection; rotational stiffness; rullskjuvning; biaxiell undersökning; spänningskombination; RT-plan; fuktpåverkan; krypning vid rullskjuving; digital bildkorrelation; töjningsfält; KLTanslutning; rotationsstyvhet; Byggteknik; Civil engineering;

    Abstract : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.
