2. 21. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

   Author : Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

   Abstract : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. READ MORE

4. 22. FLEXIBLE FIXTURES - A TREATISE ON FIXTURE DESIGN AND EFFICIENCY

   Author : Ilker Erdem; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; reconfigurable; Flexible; fixture; efficiency; tooling;

   Abstract : Even though a variety of efforts have been made in the area of flexible fixtures, the manufacturing industry still relies on dedicated fixtures with minor modular features. The main underlying reason, as these attempts have shown, is that the application of flexible fixtures has failed to yield the expected results, with the implemented technologies often leading to increased manufacturing costs when compared to dedicated fixtures.

5. 23. Cost-optimality approach for prioritisation of buildings envelope energy renovation : A techno-economic perspective

   Author : Farshid Bonakdar; Angela Sasic Kalagasidis; Keith Jones; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building renovation; Energy efficiency; Cost-optimality; costeffectiveness; Building envelope; Residential buildings; Building energy simulation; Brute-force algorithm; Sustainable Built Environment; Hållbar byggd miljö;

   Abstract : The existing residential buildings in the European countries are rather old and often fail to meet the current energy performance criteria. In Sweden, about 45% of the existing residential buildings have been constructed before 1960. READ MORE

6. 24. MATERIAL EFFICIENCY MANAGEMENT IN MANUFACTURING

   Author : Sasha Shahbazi; Magnus Wiktorsson; Marcus Bjelkemyr; Christina Jönsson; Thomas Lindhqvist; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material efficiency; industrial waste management; manufacturing; Innovation and Design; innovation och design;

   Abstract : 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. READ MORE

7. 25. Essays on University Efficiency Analysis and Entrepreneurship among University Graduates

   Author : Zara Daghbashyan; Björn Hårsman; Peter McGregor; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; universities; efficiency; entrepreneurship; education; graduates; arts education;

   Abstract : 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. READ MORE
