1. 36. Adaptive structural design - Integration of computational tools for CAD, adaptive FEM and optimization

   Författare :Per Kettil; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive; structural mechanics; optimization; integration; FEM; CAD; design;

   Sammanfattning : BackgroundConstruction is one of the largest industries with major impact on economy, environment and society. Improved structural design is important since the decisions made during the design process strongly influence all later stages, i.e. LÄS MER

3. 37. On the Design of Energy Efficient Aero Engines: Some Recent Innovations

   Författare :Rickard Avellan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbofan; aero engine; inter-turbine reheat; emissions; variable cycle; energy efficiency; propeller; NOx; MDO;

   Sammanfattning : In the light of the energy crisis of the 1970s, the old aerospace paradigm of flying higher and faster shifted towards the development of more energy efficient air transport solutions. Today, the aeronautical research and development community is more prone to search for innovative solutions, in particular since the improvement rate of change is decelerating somewhat in terms of energy efficiency, which still is far from any physical limits of aero engine and aircraft design.

4. 38. Performance Indicators. A performance prediction method for moisture safety design

   Författare :Veronica Yverås; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial Neural Network; Performance prediction; Moisture safety;

   Sammanfattning : The aims of this research project is to develop and gain knowledge about a different approach to moisture safety design based on AI in order to attain healthy buildings and relate this new approach to current practice and prospective users. Secondary data (data produced for some other purpose) was used to train Artificial Neural Networks (ANN) to predict the performance of outdoor ventilated crawl-spaces regarding microbiological smell, mould and rot.

5. 39. Verksamhetsinriktade produktstrukturer

   Författare :Leif Janson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The subject of this thesis is product development and design, based on a systematic approach. The study is based on [Hubka, V. Theory of Technical Systems. Springer Verlag, Berlin, Heidelberg, 1988] and the problem area is variance management and variation reduction due to increased product diversification. LÄS MER

7. 40. Designing for the integration of dynamic software environments in the teaching of mathematics

   Författare :Maria Fahlgren; Kenneth Ruthven; Arne Engström; Birgit Pepin; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; design research; dynamic mathematics software; intrumental orchestration; mathematics education; task design; Matematik; Mathematics;

   Sammanfattning : This thesis concerns the challenge of integrating dynamic software environments into the teaching of mathematics. It investigates particular aspects of the design of tasks which employ this type of computer-based system, with a focus on improvement, both of the tasks themselves and of the design process through which they are developed and refined.
