1. 16. Power loss minimization in electric cars by wheel force allocation

   Författare :Juliette Torinsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control allocation; electric vehicles; energy efficiency;

   Sammanfattning : The need for lowering the emission levels has never been greater than now. In the vehicle industry, electrification seems to be an irreversible way ahead but user-related challenges such as limited range delay electricity as the primary energy source for personal transportation.

3. 17. Epidemiological and Spatial Association between Arsenic Exposure via Drinking Water and Morbidity and Mortality : Population based studies in rural Bangladesh

   Författare :Nazmul Sohel; Lars Åke Persson; Marie Vahter; Pavlos Kanaroglou; Gunnar Nordberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arsenic; tube-well; skin lesion; adult mortality; foetal loss; infant death; cohort; spatial model; Bangladesh; Epidemiology; Epidemiologi; International Health; Internationell hälsa;

   Sammanfattning : The overall aim of this thesis is to evaluate the risk for increased morbidity and mortality due to long-term arsenic exposure via drinking water by use of epidemiological and spatial approaches in studies performed in Matlab, Bangladesh. A total of 166,934 individuals aged 4 years and above were screened for skin lesions in 2002-2003. LÄS MER

4. 18. High frequency electronic packaging and components : characterization, simulation, materials and processing

   Författare :Christian Johansson; Mats Robertsson; Li-Rong Zheng; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER®; permittivity; printed diode; sequential build-up; silicone elastomer; Signal processing; Signalbehandling;

   Sammanfattning : 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 and high frequency devices have led to the search for new materials, material combinations, methods, processes and production equipment.

5. 19. Volumetric Analysis in Mechanical Behaviour and Physical Ageing of Polymers

   Författare :Mats Delin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ageing rate; Gr neisen parameter; bulk modulus; KAHR model; dilatometry; Poisson s ratio; timescale; physical ageing; dynamic mechanical properties; stress relaxation; volume changes; creep; Doolittle s equation;

   Sammanfattning : Volumetric changes associated with the deformation of ideal elastic solids depends on elastic constants of the solid and applied strain. Their magnitude is easily determined from the corresponding Poisson's ratios. LÄS MER

7. 20. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

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

   Sammanfattning : 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.
