1. 1. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs

   Författare :Supratim Basu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna Factor; Diode Recovery Time; Harmonic currents; EMI; Quasi Park; Snap Factor; PFC;

   Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER

3. 2. Utilizing research in the practice of personnel selection : General mental ability, personality, and job performance

   Författare :Sofia Sjöberg; Magnus Sverke; Katharina Näswall; Marise Born; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Personnel selection; job performance; correction for range restriction; general mental ability; personality; clinical and mechanical data collection; clinical and mechanical data combination; utility; preference for hiring approach; Psychology; psykologi;

   Sammanfattning : Identifying and hiring the highest performers is essential for organizations to remain competitive. Research has provided effective guidelines for this but important aspects of these evidence-based processes have yet to gain acceptance among practitioners. LÄS MER

4. 3. The Hit-IT project : The development and evaluation of an internet-based complex intervention for primary healthcare patients with cardiovascular disease and insomnia

   Författare :Sandra Öberg; Anders Broström; Linda Johansson; Jonas Sandberg; Mattias Georgsson; Staffan Karlsson; Jönköping University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; insomnia; cognitive behavioral therapy; internet-based; utility; effect; patient experience; complex intervention;

   Sammanfattning : There is a need to explore insomnia among patients with cardiovascular disease (CVD), since they have increased risk for disease deterioration, poor quality of life and a shorter lifetime expectancy. Cognitive behavioral therapy (CBT) is the main recommended insomnia treatment, although it is a rare treatment choice in the healthcare due to lack of certified CBT therapists. LÄS MER

5. 4. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport

   Författare :Ahmet Mandev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; greenhouse gas GHG emissions; charging behavior; fuel consumption; eVKT; eVMT; PHEV Plug-in hybrid electric vehicle ; utility factor;

   Sammanfattning : The Paris Agreement emphasizes the importance of greenhouse gas mitigation in the transport sector to address climate change and create a sustainable future with lower carbon emissions. Plug-in hybrid electric vehicles (PHEVs) can be helpful in reducing greenhouse gas emissions in transportation when combined with efforts to decarbonize the electricity sector. LÄS MER

7. 5. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport - Analysis of empirical data from North America

   Författare :Ahmet Mandev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eVMT; utility factor; charging behavior; fuel consumption; eVKT; greenhouse gas GHG emissions; PHEV Plug-in hybrid electric vehicle ;

   Sammanfattning : Plug-in hybrid electric vehicles (PHEV) can help reduce the greenhouse gas emissions in the transport sector, combined with the decarbonization of the electricity sector, and play an important role in electrifying personal transport. This thesis uses empirical data from North America to investigate the role of PHEVs in electrifying personal transport, with a focus on the household context and charging behavior. LÄS MER
