  1. 1. Having a New Pair of Glassess Applying Systemic Accident Models on Road Safety

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Yu-Hsing Huang; Linköpings universitet.; Linköpings universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; TECHNOLOGY Information technology Computer science Cognitive science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Kognitionsvetenskap;

    Sammanfattning : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. LÄS MER

  2. 2. Predictive models for accidents on urban links - A focus on vulnerable road users

    Detta är en avhandling från Department of Technology and Society, Lund University

    Författare :Thomas Jonsson; Lunds universitet.; Lund University.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportteknik; Road transport technology; Transport technology; Teknik; Technological sciences; Stads- och glesbygdsplanering; Town and country planning; speed; links; urban; safety; vulnerable road users; modelling; prediction; crash; traffic safety; accident; Vägtransportteknik;

    Sammanfattning : Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable road users.

  3. 3. The Effective Convectivity Model for Simulation and Analysis of Melt Pool Heat Transfer in a Light Water Reactor Pressure Vessel Lower Head

    Detta är en avhandling från KTH : KTH

    Författare :Chi Thanh Tran; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light water reactor; hypothetical severe accident; accident progression; accident scenario; core melt pool; heat transfer; turbulent natural convection; heat transfer coefficient; phase change; mushy zone; crust; lower plenum; analytical model; effective convectivity model; CFD simulation; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik;

    Sammanfattning : Severe accidents in a Light Water Reactor (LWR) have been a subject of intense research for the last three decades. The research in this area aims to reach understanding of the inherent physical phenomena and reduce the uncertainties in their quantification, with the ultimate goal of developing models that can be applied to safety analysis of nuclear reactors, and to evaluation of the proposed accident management schemes for mitigating the consequences of severe accidents.

  4. 4. External costs of transports imposed on neighbours and fellow road users

    Detta är en avhandling från Department of Economics, Lund Universtiy

    Författare :Lena Hiselius; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2005]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic theory; economic systems; econometrics; Economics; Samhällsvetenskaper; Social sciences; Hazardous materials; Hourly traffic flow; Choice experiments; Accident prediction models; External costs; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : This thesis consists of an introductory chapter and four research papers, summarized as follows. The overall purpose is to study various external effects of the transport system; effects that are not considered (or not fully considered) today. LÄS MER

  5. 5. Assessment of Long-Term Losses in Prestressed Concrete Structures - Application for Nuclear Reactor Containments

    Detta är en avhandling från Department of Economics, Lund Universtiy

    Författare :Peter Lundqvist; Lunds universitet.; Lund University.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear reactor containments; KstrConcrete; prestressed concrete; prestress losses; bonded tendons; creep; shrinkage; relaxation; prediction models; resonance frequency; acoustoelasticity.;

    Sammanfattning : Most nuclear reactors, both in Sweden and worldwide, are enclosed by a prestressed concrete containment. The main purpose of the containment is to prevent any radioactive discharge to the environment in the event of a major internal accident. LÄS MER
