1. 26. FLEXIBLE FIXTURES - A TREATISE ON FIXTURE DESIGN AND EFFICIENCY

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

   Sammanfattning : 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.

3. 27. Heat Transfer and Energy Efficiency in Infrared Paper Dryers

   Författare :Magnus Pettersson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental; modelling; electricity; gas; efficiency; energy; drying; dryer; heat transfer; radiation; paper; infrared; IR; coating; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : Infrared (IR) dryers are widely used in the paper industry, mainly in the production of coated paper grades. The thesis deals with various aspects of heat transfer and energy use in infrared heaters and dryers as employed in the paper industry. Both gas-fired and electric IR dryers are considered and compared. LÄS MER

4. 28. Ammattilaisbyrokratiat tehokkuuden aikakaudella : tasa­painoilua asiantuntijaeetoksen ja tehokkuuspaineiden välillä

   Författare :Tomi J. Kallio; Finland Tampere University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Tässä väitöskirjatutkimuksessa tarkastellaan asiantuntijaorganisaatioita – erityisesti suomalaisia julkisomisteisia yliopisto- ja sairaalaorganisaatioita – tilanteessa, jossa pääasiassa näiden organisaatioiden ulkopuolelta tulevat paineet pakottavat niitä omaksumaan tehokkuusajattelun. Tutkimuksen lähtökohtana on ajatus siitä, että sairaala- ja yliopisto-organisaatiot, jotka Mintzbergin (1979) klassista terminologiaan soveltaen ovat malli-esimerkkejä organisaatiotyypistä, jota kutsutaan ammattilaisbyrokratiaksi, muistuttavat monilta keskeisiltä ominaispiirteiltään toisiaan.

5. 29. MATERIAL EFFICIENCY MANAGEMENT IN MANUFACTURING

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

   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

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

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

   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
