    Sammanfattning : Electrification of vehicles is an indispensable step in improving fuel economy and reducing fossil fuel emissions. In particular, hybrid electric vehicle market has gained popularity as one such reliable solution. LÄS MER

  4. 3. Improved remaining useful life estimations for on-condition parts in aircraft engines

    Författare :Veronica Fornlöf; Anna Syberfeldt; Anders Skoogh; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aircraft engine maintenance; Reliability; Remaining useful life; On-condition parts; Prognosis; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : This thesis focuses on obtaining better estimates of remaining life for on-condition (OC) parts in aircraft engines. Aircraft engine components are commonly classified into three categories, life-limited parts (LLP), OC-parts and consumables. Engine maintenance typi-cally accounts for 10% to 20% of aircraft-related operating cost. LÄS MER

  5. 4. Taxation of Cross-Border Partnerships : Double-Tax Relief in Hybrid and Reverse Hybrid Situations

    Författare :Jesper Barenfeld; Jönköping University; []
    Nyckelord :;

    Sammanfattning : International juridical double taxation constitutes a significant obstacle for the development of cross-border business activities. Even though this problem has been combated for decades with ever more sophisticated methods, many difficulties are yet to be conquered. LÄS MER

  7. 5. Co-Construction of Hybrid Spaces

    Författare :Åsa Rudström; Kristina Höök; Mikael Wiberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HCI; MMI; social computing; mobile computing; co-construction; seamfulness; awareness; hybrid space; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : When computational systems become increasingly mobile and ubiquitous, digital information and the use of computational systems may increasingly be immersed into the physical and social world of objects, people and practices. However, the digital, physical and social materials that make up these hybrid spaces have different characteristics and are hard to understand for users. LÄS MER
