16. The HCCI Engine – High Load Performance and Control Aspects
Sammanfattning : Current combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. LÄS MER
17. Techniques to Cancel Execution Early to Improve Processor Efficiency
Sammanfattning : The evolution of computer systems to continuously improve execution efficiency has traditionally embraced various approaches across microprocessor generations. Unfortunately, contemporary processors still suffer from several inefficiencies although they offer an unprecedented level of computing capabilities. LÄS MER
18. MATERIAL EFFICIENCY MANAGEMENT IN MANUFACTURING
Sammanfattning : Material efficiency is a key solution to provide a reduction in the total environmental impact of global manufacturing, which contributes to avoid generating larger volumes of industrial waste, to reduce extracting and consuming ever more resources and to decrease energy demand and carbon emissions. However, the area of material efficiency in manufacturing has been under-researched and related knowledge is limited. LÄS MER
19. Essays on University Efficiency Analysis and Entrepreneurship among University Graduates
Sammanfattning : The thesis consists of five papers: three deal with the efficiency of higher education institutions (HEI) and two with entrepreneurship among university graduates. The efficiency of HEIs is analyzed at three different levels: units of one university, universities of one country and universities of a group of European countries. LÄS MER
20. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER
