  4. 22. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

    Author : Christian Johansson; Hjalmar Hesselbom; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

    Abstract : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

  5. 23. High Arctic submarine glaciogenic landscapes : their formation and significance

    Author : Francis Fletcher Freire; Richard Gyllencreutz; Martin Jakobsson; Haflidi Haflidason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High Arctic; GrIS; marine geophysics; glaciogenic landscapes; ice streams; submarine slides; Marine Geology; maringeologi;

    Abstract : This thesis is focused on studies of glacial and slope morphology in the high Arctic of western Greenland shelf and the Molloy Hole seafloor spreading area, based on high-resolution acoustic methods and other geophysical data. The main purpose is to improve our understanding of glacial dynamics and associated processes in the marginal region of a large marine-terminating ice sheet. READ MORE

  7. 25. High Repetition Rate Laser Diagnostics for Combustion Applications

    Author : Johan Sjöholm; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spray; diesel; optical engine; simultaneous; laser-induced fluorescence; fuel tracer; SLIPI; Raman; LII; laser diagnostic; combustion; high repetition rate; high-speed; PLIF; multi-YAG; LIF; fuel jet; Fysicumarkivet A:2012:Sjöholm;

    Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE
