  2. 16. Characterisation of Nonlinear Structural Dynamic Systems in Conceptual Design

    Author : Niclas S Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural dynamics; Model order reduction; Nonlinear characterisation; Multi-body dynamics; Frequency response functions; Multisines; Response classification; Driveline systems; Concept design analysis; Stepped-sine; Support vector machine;

    Abstract : The engine and driveline systems of passenger cars generates and distributes the necessary driving power and are major contributors to vehicle emissions, noise and vibrations, etc. More environmental friendly technologies under development are expected to intensify and add new comfort related problems, since most of them affect vibration sources or system damping.

  4. 17. Measurement accuracy. Applications in X-ray computed tomography (CT) dose reduction and magnetic resonance spectroscopy (MRS) volume selection

    Author : Göran Starck; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; Radiation exposure; Image quality; Tissue characterisation; MRS volume selection; Signal profile; Phantom; Magnetic susceptibility;

    Abstract : X-ray computed tomography (CT) images of transaxial cross sections of the body can be used to determine tissue volumes. However, the considerable radiation dose associated with high-quality clinical images has greatly limited the use of CT for this application. READ MORE

  5. 18. Hybrid Solar Gas-Turbine Power Plants : A Thermoeconomic Analysis

    Author : James Spelling; Andrew Martin; Björn Laumert; David Tomas Sanchez Martinez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar thermal power; hybrid gas-turbine; thermoeconomics; koncentrerad solenergi; gas-turbiner; ekonomisk analys;

    Abstract : The provision of a sustainable energy supply is one of the most importantissues facing humanity at the current time, and solar thermal power hasestablished itself as one of the more viable sources of renewable energy. Thedispatchable nature of this technology makes it ideally suited to forming thebackbone of a future low-carbon electricity system. READ MORE

  6. 19. Automatic generation of configurable test-suites for software product lines

    Author : Vanderson Hafemann Fragal; Mohammad Reza Mousavi; Adenilso da Silva Simão; Andrzej Wasowski; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Software Product Line Engineering (SPLE) is an approach used in the development of similar products, which aims at systematic reuse of software artifacts. The SPLE process has several activities executed to assure software quality. READ MORE

  7. 20. Theoretical Studies on Artificial Water Splitting-Water Oxidation and Proton Transfer

    Author : Ying Wang; Hans Ågren; James Gardner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The present thesis is concerned with the theoretical studies on artificial water splitting process. As the quick development of research on utilizing of solar energy, which is a green, clean, and renewable energy source, many research groups focus their attention on artificial photo-synthesis systems inspired by the photosystem I and II.
