1. 16. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

   Författare :Ilker Erdem; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; design; fixture; assembly; manufacturing; efficiency; flexible; production;

   Sammanfattning : The manufacturing industries have been using flexible production technologies to meet the demand for customisation. As a part of production, fixtures have remained limited to dedicated technologies, even though numerous flexible fixtures have been studied and proposed by both academia and industry. LÄS MER

3. 17. High efficiency power amplifiers for wireless communications

   Författare :Hossein Mashad Nemati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load modulation; GaN; supply modulation; LDMOS; efficiency; Power amplifier; MMIC; mHEMT; transmitter architecture;

   Sammanfattning : This thesis presents state-of-the-art high efficiencyharmonically-tuned power amplifiers (PAs) and investigates thecharacteristics and potentials of such amplifiers in two of the mostpromising efficiency enhancement techniques, dynamic supply and load modulation.In this work, a 10 W LDMOS harmonically-tuned PA with 80% power-added-efficiency (PAE) isrealized at 1 GHz.

4. 18. Adaptability or Efficiency : Towards a theory of institutional development in organizations

   Författare :Mikael Klingvall; Göran Ahrne; Fredrik Liljeros; Felix Reed-Tsochas; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational development; social influence; organizational culture; institutional development; adaptability; agent-based model; Sociology; Sociologi; Sociology; sociologi;

   Sammanfattning : Organizations, once established, tend not to change, typically going obsolete as society continues to evolve. This makes adaptability an important issue. Organizational members must make sense to each other, or coordination suffers. LÄS MER

5. 19. Organizing for efficiency : Essays on merger policies, independence of authorities, and technology diffusion

   Författare :Anh Mai; Mats Bergman; Lars Hultkrantz; Ranjula Bali Swain; Lars Persson; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; merger; regulation; reform; authority; corruption; broadband; diffusion; policy; industrial organization; accountability; Politics; Economy and the Organization of Society;

   Sammanfattning : Institutions are fundamentally sets of rules in a society that help create stability. Organizations are groups of people who may share the same goal. Changes in organizations and institutions will have large effects on the performance of economies. LÄS MER

7. 20. The Non-Energy Benefits of Industrial Energy Efficiency : Investments and Measures

   Författare :Therese Nehler; Patrik Thollander; Elin Svensson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy efficiency; energy efficiency measures; energy efficiency investments; non-energy benefits; compressed air;

   Sammanfattning : Improved industrial energy efficiency is viewed as an important means in the reduction of CO2 emissions and climate change mitigation. Various energy efficiency measures for improving energy efficiency exists, but even evaluated as cost-effective, there seems to be a difference between the energy efficiency measures that theoretically could be undertaken and which measures that actually are realised.
