  1. 1. On Hazard Identification in the Automotive Domain

    Author : Fredrik Törner; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hazard Identification; Hazard Analysis; Automotive; Quality of Use Cases;

    Abstract : Electrical systems in vehicles are becoming more important with every new generation of cars since the functional growth in the automotive industry is mainly realized by electronics. The new functionalities can for instance be advanced safety improving systems or electronics replacing mechanical system solutions. READ MORE

  2. 2. Organizational Lessons Learned : Natural Hazards Affecting Critical Infrastructure

    Author : Monika Rydstedt Nyman; Lars Nyberg; Magnus Johansson; Eva Liljegren; Henrik Tehler; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; natural hazards; critical infrastructure; feedback; lessons learned; collective learning; memory building; Risk and Environmental Studies; Risk- och Miljöstudier;

    Abstract : This thesis focuses on an issue often presented as a solution – albeit a debated one ­– namely learning, specifically lessons learned from natural hazard events. Empirically, this thesis examines flooding and avalanches in a Swedish context, centering on systematic feedback mechanisms and learning from extreme events. READ MORE

  3. 3. On Hazard Identification and Safety Cases In the Automotive Domain

    Author : Fredrik Törner; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Safety Case; Hazard Analysis; Hazard Identification; Automotive;

    Abstract : Since electronics is the enabling factor for functional growth in many automotive engineering areas, the electrical system of a vehicle is becoming increasingly important for every new vehicle generation. Many new functions implemented in electronics are safety related, which raises new requirements on how to ensure the safety of automotive electronic systems. READ MORE

  4. 4. Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools

    Author : Daniel Ragnvaldsson; Mats Tysklind; Per Leffler; Lars Lövgren; Bengt-Erik Bengtsson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hazard screening; bioavailability; metal pollution; in vitro cytotoxicity; water extraction; CCA; arsenic genotoxicity; genotoxicity; Contaminated soil; Environmental chemistry; Miljökemi;

    Abstract : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. READ MORE

  5. 5. Statistical Seismology Studies in Central America : b-value, seismic hazard and seismic quiescence

    Author : David Aníbal Monterroso Juárez; Ota Kulhánek; Stefan Wiemer; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Geophysics; b-value; seismic hazard; Monte Carlo; seismic quiescence; Central America; stress; Geofysik; Geophysics; Geofysik;

    Abstract : The present thesis collects results of research applying theory and methods of statistical seismology to the seismicity of Central America, a region with a complex tectonic setting controlled by the interaction of four major plates, namely the Caribbean, Cocos, Nazca and North American plates.Three different earthquake catalogues were used for studies focused on stress in a tectonic volume, seismic hazard maps and seismicity patterns (precursors), covering the region 94ºW to 81ºW and 5ºN to 20ºN.
