1. 1. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land

   Författare :Pär-Erik Back; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty; decision analysis; risk; sampling; data worth; soil sampling; contaminated land;

   Sammanfattning : Contaminated soil and groundwater is a problem that has received increased attention in the last decade. Decision-making about investigation strategies, protective actions, and remedial actions is based on sparse and uncertain information, primarily data of contaminant concentrations and geological information.

3. 2. On Bayesian Decision Analysis for Evaluating Alternative Actions at Contaminated Sites

   Författare :Jenny Norrman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; influence diagrams; Bayesian decision analysis; groundwater; data worth analysis; contaminated sites; decision analysis; risk analysis;

   Sammanfattning : Today, contaminated land is a widespread infrastructural problem and it is widely recognised that returning all contaminated sites to background levels, or even to levels suitable for the most sensitive land use, is not technically or financially feasible. The large number of contaminated sites and the high costs of remediation, are strong incentives for applying cost-efficient investigation and remediation strategies that consider the inherent uncertainties.

4. 3. Integrative Approaches in Shotgun Proteomics : From sample preparation to multifaceted data analysis

   Författare :Mariya Nezhyva; Erik T. Jansson; Per Andrén; Gustaf Christoffersson; Jesper Velgaard Olsen; Uppsala universitet; []
   Nyckelord :bottom-up proteomics; thermal proteome profiling; mass-spectrometry imaging; data analysis; melanocortin receptor; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Bottom-up proteomics mass-spectrometry gives an opportunity to shed light on var-ious biological aspects/characteristics such as protein composition, its modifications,interactions, and dynamics. Its applications span a wide range of biological sciencesaiming to eventually answer fundamental disease related questions or evaluate drugperformance and predict adverse effects. LÄS MER

5. 4. Visual analytics for maritime anomaly detection

   Författare :Maria Riveiro; Göran Falkman; Tom Ziemke; Dag Stranneby; Mikael Jern; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual analytics; anomaly detection; maritime traffic monitoring; analytical reasoning; information fusion; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Datalogi; Computer and Systems Science; Technology;

   Sammanfattning : The surveillance of large sea areas typically involves  the analysis of huge quantities of heterogeneous data.  In order to support the operator while monitoring maritime traffic, the identification of anomalous behavior or situations that might need further investigation may reduce operators' cognitive load.

7. 5. What is a life worth? : methodological issues in estimating the value of a statistical life

   Författare :Mikael Svensson; Lars Hultkrantz; Magnus Johannesson; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value of a statistical life; scale bias; cognitive ability; hypothetical bias; cost-benefit analysis; calibration; certainty approach; attitude theory; seat belt use; bicycle helmet use; altruism; mortality rates; acute myocardial infarction; unemployment.; Economics; Nationalekonomi; Economics; Nationalekonomi;

   Sammanfattning : This thesis addresses methodological issues in estimating the value of a statistical life (VSL). Two main approaches have been used to estimate the VSL, the indirect and direct methods; the indirect method is based on revealed preferences, such as the wage premium demanded for a risky job.
