2. 1. ZrN Back-Contact Reflectors and Ga Gradients in Cu(In,Ga)Se2 Solar Cells

   Author : Sebastian Michael Schleussner; Marika Edoff; Tobias Törndahl; Uwe Zimmermann; Dieter Schmid; Uppsala universitet; []
   Keywords : Solar cells; CIGS; ZrN; three-stage process; multi-stage process; grading; SIMS; electrical modelling; NATURAL SCIENCES; NATURVETENSKAP; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : Solar cells constitute the most direct way of converting solar energy to electricity, and thin-film solar-cell technologies have lately been growing in importance, allowing the fabrication of less expensive modules that nonetheless have good power-conversion efficiencies. This thesis focuses on solar cells based on Cu(In,Ga)Se2, which is the thin-film technology that has shown the highest conversion efficiency to date, reaching 20. READ MORE

   Abstract : In this thesis, priority setting to the form of the Swedish parliamental decision on priority setting, 1997, is considered an innovation for implementation in health care. The features of this innovation are investigated. READ MORE

5. 3. Optimization and Model Validation of Transonic Compressors

   Author : Lars R Ellbrant; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressor; optimization; design; metamodels; CFD; validation; multiobjective;

   Abstract : Economical aspects such as reduced specific fuel consumptions and ever growing environmental requirements on emissions and percieved noise levels, are the major drivers in the search for improvement of aircraft engines. For turbofan engines, the global trend is towards higher efficiency which is accomplished by increasing component efficiencies, the bypass ratio and overall pressure ratio while keeping the engine weight low.

6. 4. Multi-objective CFD-based design method for axial compressors

   Author : Lars R Ellbrant; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q3D; Turbomachinery; Design; Meta-modeling; Optimization; CFD; Validation; Compressor; Transonic;

   Abstract : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. READ MORE

7. 5. Swift transition and knowledge cycling : A study of knowledge transfer in technical consulting

   Author : Svjetlana Pantic-Dragisic; Jonas Söderlund; Cecilia Enberg; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Professional service firm; technical consulting firm; technical consultants; mobile engineers; knowledge transfer; mobility; swift transition; knowledge cycling; formal training;

   Abstract : The prominent shifts towards greater flexibility in work arrangements as well as in organizational forms have had profound effects on the labor market for engineers, and given rise to the technical consulting industry. The technical consulting firm is becoming increasingly important in many technology-based industries, as a growing number of technology-based firms rely on technical consulting firms to produce their outputs.
