  2. 1. Testing of Heterogeneous Systems

    Author : Nauman Ghazi; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Testing; Heterogeneous systems; Information sources; Test selection;

    Abstract : Context: A system of systems often exhibits heterogeneity, for instance in implementation, hardware, process and verification. We define a heterogeneous system, as a system comprised of multiple systems (system of systems) where at least one subsystem exhibits heterogeneity with respect to the other systems. READ MORE

  4. 2. Software Testing in Agile Development : Technological and Organisational Challenges

    Author : Adnan Čaušević; Sasikumar Punnekkat; Feldt Robert; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software testing; agile development; test-driven development; role of testers; empirical study; controlled experiment; Software engineering; Programvaruteknik; Computer Science; datavetenskap;

    Abstract : The emerging industrial trend towards agile software development processes brings forth new concerns, challenges as well as opportunities. One of the main concerns is with respect to the achievable quality levels of the final product, for which testing is the well-known assurance mechanism. READ MORE

  5. 3. Weldability of Precipitation Hardening Superalloys – Influence of Microstructure

    Author : Joel Håkan Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot cracking; GTAW; Transvarestraint testing; Varestraint testing; Gleeble testing; Solidification cracking; HAZ liquation cracking; Repair welding; Strain age cracking; EBW; DSC thermal analysis;

    Abstract : Superalloys and in particular the precipitation hardened Ni-based superalloys havealways been used extensively in the hot sections of jet engines. Large hot structuralengine components with complex geometry have preferably been cast as single piececomponents since the large scale vacuum investment casting process becameavailable about fifty years ago.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Empirical Research; Industrial Case Study; Automated Testing; Industrial Applicability; System Testing; Software Engineering; Visual GUI Testing;

    Abstract : There is constant pressure on the software development industry to improve software quality and deliver new and innovative software faster and more efficiently. These demands affect all aspects of software development, from requirements engineering to testing. READ MORE

  7. 5. Ultrasonic testing of components produced with additive manufacturing : Towards improved detection and classification of defects

    Author : Mikael Sahl; Håkan Wirdelius; Erik Lindgren; Oskar Tofeldt; Madis Ratassepp; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-Destructive Testing NDT ; Super alloys; Microstructure; Ultrasonic Testing UT ; Productivity Enhancement; Production Technology; Produktionsteknik;

    Abstract : The focus in this work is on the use of ultrasonic testing as a method for inspecting components manufactured through additive manufacturing (AM) processes. The research is rooted in the need for effective non-destructive testingtechniques that can adapt to the unique challenges posed by AM-produced materials, including complex defect geometries and surface conditions.
