  1. 1. End-Shield Bridges for High-Speed Railway Full scale dynamic testing and numerical simulations

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hesham Elgazzar; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.

  2. 2. Structural System-Level Testing of Embedded Real-Time Systems

    University dissertation from Akademin för innovation, design och teknik

    Author : Daniel Sundmark; Mälardalens högskola.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time systems; testing; monitoring; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Datavetenskap;

    Abstract : People make mistakes. Software engineers are no exception to this fact. When software engineers make mistakes, these manifest in the form of buggy software - a major problem in today's industry. READ MORE

  3. 3. Exploring dementia care dyads' person transfer situations from a behavioral medicine perspective in physiotherapy development of an assessment scale

    University dissertation from Örebro : Örebro university

    Author : Charlotta Thunborg; Örebro universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Behavioral medicine in physiotherapy; Care dyad; Dementia; Intervention; Scale development; Transfer problems; Vårdvetenskap; Nursing Science; Geriatrik; Geriatrics;

    Abstract : Individuals who suffer from severe dementia require assistance when performing activities of daily living. The highly important person transfer situation is influenced by complex, intertwined biopsychosocial factors that are related to the expression of personal, environmental and behavioral variables, which can interfere with the performance of dementia-care dyads' transfer situations.

  4. 4. Weldability of Precipitation Hardening Superalloys – Influence of Microstructure

    University dissertation from Örebro : Örebro university

    Author : Joel Håkan Andersson; [2011]
    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.

  5. 5. Energy Consumption and Running Time for Trains modelling of running resistance and driver behaviour based on full scale testing

    University dissertation from Stockholm : KTH

    Author : Piotr Lukaszewicz; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. READ MORE
