2. 1. Spatial modelling and simulation for disease surveillance

   Author : Mohammadreza Rajabi; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GISgeografiska informationssystem; Agent Based Modeling; spatial epidemiology; machine learning;

   Abstract : This thesis addresses the application of spatial approaches to disease surveillance and control from three different aspects. First, temporal trends, geographical distribution and spatial pattern of cardiovascular disease admission rates were explored on a national level in Sweden. READ MORE

4. 2. Stochastic analysis of fluid flow and tracer pathways in crystalline fracture networks

   Author : Andrew Frampton; Vladimir Cvetkovic; Allen Shapiro; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Fractured media; Transport; Retention; Macrodispersion; Lagrangian formulation; Stochastic modelling; Earth sciences; Geovetenskap; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

   Abstract : Understanding groundwater flow systems and how these control transport is an essential part in assessing the suitability of subsurface environments as hosts for storage of toxic waste. Therefore it is important to be able to integrate knowledge obtained from field characterisation of the subsurface with methods which can be used to evaluate and predict possible impact on surrounding environments.

5. 3. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation

   Author : Verity Borthwick; Sandra Piazolo; Dorte Juul Jensen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; halite; in-situ; X-ray diffraction; EBSD; annealing; substructure; modelling; Earth sciences; Geovetenskap; Geology; geologi;

   Abstract : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. READ MORE

6. 4. Development, application, and reliability of methods for ergonomic workload assessments in production evaluation and workstation design

   Author : Ida-Märta Rhen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Work-related Musculoskeletal Disorders; Risk assessment; Direct measurement; Biomechanical Exposure; Systematic Observation; Digital Human Modelling; Ergonomics; Workplace Design; Simulation; Reliability;

   Abstract : Ergonomics assessments of conditions for humans at workstations and in manufacturing processes are necessary to prevent work-related musculoskeletal disorders and enhance efficiency and quality. Many methods can be used for this from systematic observations to direct measurements and simulation. READ MORE

7. 5. Trade-off analysis of forest ecosystem services – A modelling approach

   Author : Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy feedstock; Landscape simulation; Forest simulation; Ecosystem services modelling; Integrated sustainability assessment; Spatial optimization; Optimization heuristics; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Forest is a resource that is increasingly utilized for multiple purposes. The balance between energy demands and the long-term capacity of ecosystems to support biodiversity and other ecosystem services is crucial. READ MORE
