1. 21. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment

   Författare :Gabriele Bertoli; Christophe Clement; Martijn Mulders; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; CERN; large extra dimensions; supersymmetry; compressed; squark; neutralino; monojet; ADD; standard model; fysik; Physics;

   Sammanfattning : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. LÄS MER

3. 22. Estimations of Hydrogeological Properties in Vulnerability and Risk Assessments

   Författare :Lars Rosen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; groundwater; Markov; conceptual model; Bayes; risk; vulnerability;

   Sammanfattning : The main objective of this thesis was to evaluate and develop approaches for hydrogeological vulnerability and risk assessments, starting with scant data and updating the results as new information becomes available. This work was performed within three separate projects between 1989 and 1995. LÄS MER

4. 23. Optimal strategies and information in foraging theory

   Författare :Emma Sernland; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian foraging; information use; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi; NATURAL SCIENCES; NATURVETENSKAP; Other biology; Övrig biologi; Naturvetenskap; Natural sciences; information use; Bayesian foraging; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi;

   Sammanfattning : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. LÄS MER

5. 24. Grid frequency stability from a hydropower perspective

   Författare :Elin Dahlborg; Per Norrlund; Urban Lundin; Linn Saarinen; Katherine Elkington; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; frequency stability; grid codes; hydropower; inertia; Kaplan unit; model validation; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Many AC grids suffer from decreased frequency stability due to less system inertia. This has increased the risk of large-scale blackouts. This thesis and its papers address the frequency stability problem from a hydropower perspective.Grid frequency stability assessments often require accurate system inertia estimates. LÄS MER

7. 25. Towards a Health Economic Simulation Model of Type 2 Diabetes in Sweden

   Författare :Aliasghar Ahmad Kiadaliri; Hälsoekonomi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The aim of this thesis was to provide part of the data required in updating/developing computer simulation models (CSMs) for type 2 diabetes mellitus (T2DM) using data obtained from routine clinical practice in Sweden. In paper I, evolution of five biomarkers (i.e. LÄS MER
