6. The Compression/Absorption Heat Pump Cycle - System Simulations
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

7. Wood fibre deformation in combined shear and compression
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

8. On the compression properties of paper - implications for calendering
Abstract : The objective of this work was to study and describe thedeformation of paper in the thickness direction in a calendernip that in some cases was heated. The temperature distributionin the thickness direction was evaluated using modelexperiments. READ MORE

9. Creation and destruction of in-cylinder flows : Large eddy simulations of the intake and the compression strokes
Abstract : The aim of this thesis is to increase engine efficiency by studying the flow structures created in an engine cylinder during the intake phase and the effect of the subsequent compression.The invention of the combustion engine has enabled three centuries of economic growth fueled by energy stored as hydrocarbons.

10. Approximation and Compression Techniques to Enhance Performance of Graphics Processing Units
Abstract : A key challenge in modern computing systems is to access data fast enough to fully utilize the computing elements in the chip. In Graphics Processing Units (GPUs), the performance is often constrained by register file size, memory bandwidth, and the capacity of the main memory. READ MORE
