2. 1. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

   Author : ADRIAN NILSSON DAHLQVIST; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

   Abstract : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

4. 2. Striving for meaning - a study of innovation processes

   Author : Åsa Öberg; Yvonne Eriksson; Roberto Verganti; Koenraad Debackere; Mälardalens högskola; []
   Keywords : HUMANIORA; HUMANITIES; meaning; interpreting; innovation process; hermeneutics; exposing; criticising; mening; tolkande; innovations processer; hermeneutik; blottlägga; kritiskt förhållningssätt; Innovation and Design; innovation och design;

   Abstract : Traditionally, innovation processes have often focused on creatively solving problems with the help of new technology or business models. However, when describing products in terms of function or visual appearance, the reflection on a less visible dimension, the product meaning, is left out. READ MORE

5. 3. Bringing fuel cells to reality and reality to fuel cells : A systems perspective on the use of fuel cells

   Author : Maria Saxe; Per Alvfors; Angelo Moreno; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assessment; CUTE; Demonstration projects; Emerging technology; Evaluation; Fuel cell buses; Fuel cell systems; Fuel cells; Hype; Interdisciplinary; Niche markets; PEM; Radical technologies; SOFC; Strategic niche markets; Sustainability; Chemical energy engineering; Kemisk energiteknik;

   Abstract : With growing awareness of global warming and fear of political instability caused by oil depletion, the need for a society with a sustainable energy system has been brought to the fore. A promising technology often mentioned as a key component in such a system is the fuel cell technology, i.e. READ MORE

6. 4. On aircraft fuel systems : conceptual design and modeling

   Author : Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

   Abstract : The largest and most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. READ MORE

7. 5. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass

   Author : Nils Skoglund; Dan Boström; Rainer Backman; Franz Winter; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorus; biomass; combustion; ash chemistry; fuel design; ash transformation; phosphorus-rich; ash-forming elements; fuel fingerprint; ash transformation reactions; Lewis base; Lewis acid; oorganisk kemi; Inorganic Chemistry;

   Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE
