1. Some Problems in Quantified Security
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
2. Cancer Risk Assessment of Glycidol : Evaluation of a Multiplicative Risk Model for Genotoxic Compounds
Sammanfattning : Humans are exposed to chemical compounds in everyday life, both from the environment and from endogenous processes. Some compounds constitute a risk for cancer development. One such compound is glycidol, which is genotoxic and an animal carcinogen. It is the model compound of this work, partly due to its presence in food. LÄS MER
3. Accident Risk and Environmental Assessment : Development of an Assessment Guideline with Examination in Northern Scandinavia
Sammanfattning : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. LÄS MER
4. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden
Sammanfattning : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. LÄS MER
5. From data to decision - learning by probabilistic risk analysis of biological invasions
Sammanfattning : Predicting an uncertain future with uncertain knowledge is a challenge. The success of efforts to preserve biodiversity, to maintain biosecurity and to reduce a negative impact from climate change, depend on scientifically based predictions of future events. LÄS MER
