1. 1. An Integrated System-Level Design for Testability Methodology

   Författare :Erik Larsson; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital systems; Test design; System-on-chip; Hardware; Systems design; Testing; Dissertations; Hårdvara; Systemutveckling; Testning; Databehandling Systemutveckling; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : HARDWARE TESTING is commonly used to check whether faults exist in a digital system. Much research has been devoted to the development of advanced hardware testing techniques and methods to support design for testability (DFT). LÄS MER

3. 2. Flight Test System Identification

   Författare :Roger Larsson; Martin Enqvist; Lennart Ljung; Roy Smith; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. LÄS MER

4. 3. Dynamic characteristics of automobile exhaust system components

   Författare :Thomas Englund; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Correlation; Exhaust system; Experimental investigation; Finite element model; Flexible joint; Modal analysis; Non-linear; Simplified modelling; Structural dynamics; Updating;

   Sammanfattning : Demands on emission control, and low vibration and noise levels have made the design of automobile exhaust systems a much more complex task over the last few decades. This, combined with increasing competition in the automobile industry, has rendered physical prototype testing impractical as the main support for design decisions. LÄS MER

5. 4. Track circuits’ robustness : Modeling, measurement and simulation

   Författare :Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER

7. 5. Sustainable Personal Road Transport : The Role of Electric Vehicles

   Författare :Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

   Sammanfattning : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. LÄS MER
