  2. 6. Continuous Fibre Reinforced Oxide/Oxide Composites

    Author : Magnus Holmquist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE

  4. 7. Enhancing Temporal Logic Falsification of Cyber-Physical Systems using multiple objective functions and a new optimization method

    Author : Zahra Ramezani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Testing; Falsification; Cyber-Physical Systems;

    Abstract : Cyber-physical systems (CPSs) are engineering systems that bridge the cyber-world of communications and computing with the physical world. These systems are usually safety-critical and exhibit both discrete and continuous dynamics that may have complex behavior. Typically, these systems have to satisfy given specifications, i.e. READ MORE

  5. 8. Realizing the systematic reuse of automated acceptance tests in practice

    Author : Mohsin Irshad; Kai Petersen; Jürgen Börstler; Nauman Ali; Andy Zaidman; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Reuse; Software Engineering; Development; Testing; Programvaruteknik; Software Engineering;

    Abstract : Context: Automated acceptance testing has become a relevant practice of agile software development (e.g., Extreme Programming). Automated acceptance tests (AATs) are closely tied to requirements and provide a mechanism for continuous validation of requirements as system-level tests. READ MORE

  6. 9. Testing of Doppler Ultrasound Systems

    Author : Andrew Walker; Per Ask; Ivar Ringqvist; Bengt Wranne; Birger Wandt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Blood and tissue velocities are measured and analyzed in cardiac, vascular, and other applications of diagnostic ultrasound. Errors in system performance might give invalid measurements.We developed two moving string test targets and a rotating cylinder phantom (Doppler phantoms) to characterize Doppler ultrasound systems.

  7. 10. Continuous Welded Railway Rails: Residual Stress Analyses, Fatigue Assessments and Experiments

    Author : Anders Skyttebol; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; laser cladding; plasticity; rolling contact; computational welding mechanics; materials testing; flash butt welding; fatigue; railway rails; fatigue crack propagation; finite element method;

    Abstract : Railway rails are today often continuously welded. This type of joint generally requires less maintenance than is needed for the bolted joints. It has also reduced wheel damage and made the ride more comfortable. However, these joints are subject to damage. READ MORE
