   Författare :Joakim Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SBD; high-power microwave devices; Silicon Carbide; diode mixer; wide band gap devices; physical simulations; resistive mixer; microwave devices; MESFET; Schottky diode;

   Sammanfattning : This work deals with silicon carbide (SiC) microwave devices. It treats two devices; the Schottky diode and the metal semiconductor field effect transistor (MESFET). Different MESFET materials, fabrication processes, theoretical models for physical simulation, and device models are presented. LÄS MER

3. 2. Simulator-Based Design : Methodology and vehicle display application

   Författare :Torbjörn Alm; Kjell Ohlsson; Martin Helander; Peter Hancock; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulator-Based Design SBD ; Human-in-the-loop simulators; Virtual prototyping; In-vehicle systems; Human-machine interaction HMI ; 3D situation displays; Adaptive interfaces; Work sciences and ergonomics; Arbetsvetenskap och ergonomi;

   Sammanfattning : Human-in-the-loop simulators have long been used in the research community as well as in industry. The aviation field has been the pioneers in the use of simulators for design purposes. In contrast, corresponding activities in the automotive area have been less widespread. LÄS MER

4. 3. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids

   Författare :Jang-Kwon Lim; Hans-Peter Nee; Mietek Bakowski; Ichiro Omura; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; junction field-effect transistors JFETs ; junction barrier schottky diode JBS ; schottky barrier diode SBD ; buried-grid BG technology; simulation; implantation; epitaxial growth; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. LÄS MER

5. 4. Applying lean principles and set-based approaches in product development

   Författare :Mikael Ström; RISE Research Institutes of Sweden; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Set-based design; Controlled convergence; Concept development; Lean product development; Lean transformation; Industrial introduction;

   Sammanfattning : The research described in this thesis addresses the problem of transformation to lean product development (LPD) and how to introduce and support the use of set-based design (SBD) in the concept development process. The original description of SBD does not define how to generate, evaluate and reduce a set of design solutions. LÄS MER

7. 5. On Material Modelling of High Strength Steel Sheets

   Författare :Rikard Larsson; Larsgunnar Nilsson; Odd-Sture Hopperstad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material modelling;

   Sammanfattning : The work done in this thesis aims at developing and improving material models for use in industrial applications.The mechanical behaviour of three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models of their behaviour have been developed.
