    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. LÄS MER

  3. 2. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

    Författare :Andreas Lindhe; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

    Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER

  4. 3. Essays on Shocks, Welfare, and Poverty Dynamics: Microeconometric Evidence from Ethiopia

    Författare :Yonas Alem; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban Ethiopia; poverty dynamics; dynamic probit; hazard rate; labor market status; subjective well-being; policymakers; life satisfaction; environment; Ethiopia; food price; consumer demand; fertilizer use; rainfall; highlands of Ethiopia; panel data; consumption; welfare; food price shock; Africa;

    Sammanfattning : Five self-contained papers constitute this thesis. Paper 1: Does fertilizer use respond to rainfall variability? Panel data evidence from urban Ethiopia In this article, we use farmers’ actual experiences with changes in rainfall levels and their responses to these changes to assess whether patterns of fertilizer use are responsive to changes in rainfall patterns.

  5. 4. Towards reliable seismic hazard assessment in underground mines

    Författare :Wille Törnman; Savka Dineva; Jesper Martinsson; Adam Jonsson; Björn Lund; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to  design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.

  7. 5. Assessment of induced seismic hazard and excavation damage in deep underground mines

    Författare :Emilia Nordström; Savka Dineva; Erling Nordlund; Johan Wesseloo; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Mining is a continuous process of extracting valuable minerals from the earth. It is an important part of human society and development that we cannot live without.  Although, it requires an extensive amount of resources, underground mining is comparatively faster and more environmental feasible over surface mining.
