  1. 1. Empirical Studies on Economic and Financial Spillovers : Asymmetric Risk and Dependence Modeling

    Författare :Axel Hedström; Gazi Salah Uddin; Ali M. Ahmed; Ugur Soytas; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spillovers; systemic risk; risk modeling; risk dependence; asymmetric risk; energy finance; Spillovers; systemisk risk; riskmodellering; risk påverkan; asymmetrisk risk; energifinans;

    Sammanfattning : Financial assets are volatile, and volatility becomes more intense in terms of size and rate of recurrence when markets are uncertain and growing rapidly. The fact that the recurrence rate increased during crisis periods, such as the IT bubble in the early 2000 and the global financial crisis that started in 2007, is a key finding in the literature.

  3. 2. Population modeling using harpacticoid copepods : Bridging the gap between individual-level effects and protection goals of environmental risk assessment

    Författare :Elin Lundström Belleza; Magnus Breitholtz; Annemette Palmqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population modeling; Eco toxicity tests; Environmental risk assessment; Harpacticoid copepods; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : To protect the environment from contaminants, environmental risk assessment (ERA) evaluates the risk of adverse effects to populations, communities and ecosystems. Environmental management decisions rely on ERAs, which commonly are based on a few endpoints at the individual organism level. LÄS MER

  4. 3. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods

    Författare :Fredrik Jonsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; methyl chloride; dichloromethane; toluene; styrene; uncertainty; intra- individual variability; risk assessment; physiologically based modeling; Markov chain Monte Carlo; PBPK; Bayesian; population modeling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Sammanfattning : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. LÄS MER

  5. 4. Some Problems in Quantified Security

    Författare :Vilhelm Verendel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer security; quantified risk; quantified security; risk behavior; operational risk; security metrics; information security; survey; quantitative models; decision-making; risk perception;

    Sammanfattning : This thesis contains work related to quantitative representation and analysis of computer and information security. The ability to accurately describe security using quantitative methods could offer better control and evaluation of security in operational settings. LÄS MER

  7. 5. Modeling and Calibration of Preparative Chromatography

    Författare :Niklas Borg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modeling; Simulation; Calibration; Model based analysis;

    Sammanfattning : In my thesis, I have modeled adsorption chromatography and simulated, calibrated, and analyzed models of adsorption chromatography. While my main focus has been modeling and calibration of the models by estimating the parameters, the models used have been partly new. LÄS MER
