    Sammanfattning : Several aspects make today’s transport system non-sustainable:• Production, transport and combustion of fossil fuels lead to global and local environmental problems.• Oil dependency in the transport sector may lead to economical and political instability. LÄS MER

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

    Detta är en avhandling från Skövde : University of Skövde

    Författare :Veronica Fornlöf; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aircraft engine maintenance; Reliability; Remaining useful life; On-condition parts; Prognosis; Technology; Teknik;

    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

  3. 3. Dynamic Resampling for Preference-based Evolutionary Multi-objective Optimization of Stochastic Systems Improving the efficiency of time-constrained optimization

    Detta är en avhandling från Skövde : Högskolan i Skövde

    Författare :Florian Siegmund; Högskolan i Skövde.; Högskolan i Skövde.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolutionary multi-objective optimization; simulation-based optimization; guided search; preference-based optimization; reference point; decision support; noise; stochastic systems; dynamic resampling; budget allocation; sequential sampling; hybrid; ranking and selection; Natural sciences; Naturvetenskap; Technology; Teknik;

    Sammanfattning : In preference-based Evolutionary Multi-objective Optimization (EMO), the decision maker is looking for a diverse, but locally focused non-dominated front in a preferred area of the objective space, as close as possible to the true Pareto-front. Since solutions found outside the area of interest are considered less important or even irrelevant, the optimization can focus its efforts on the preferred area and find the solutions that the decision maker is looking for more quickly, i.

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

    Detta är en avhandling från Jönköping : Internationella Handelshögskolan

    Författare :Jesper Barenfeld; Högskolan i Jönköping.; [2005]
    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

  5. 5. Co-Construction of Hybrid Spaces

    Detta är en avhandling från Kista : Institutionen för data- och systemvetenskap (tills m KTH)

    Författare :Åsa Rudström; Stockholms universitet.; RISE.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap; HCI; MMI; social computing; mobile computing; co-construction; seamfulness; awareness; hybrid space; social navigation; social mobile service; seamful design; user appropriation.;

    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
