2. 1. Simulation of welding and heat treatment : modelling and validation

   Author : Henrik Alberg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : Many aerospace components with complex geometry are fabricated from smaller parts using joining techniques such as welding. Welding and the heat treatment which usually follows, can result in unwanted deformation and stresses. READ MORE

4. 2. Zebrafish models for large-scale genetic screens in dyslipidemia and atherosclerosis : Validation and application

   Author : Manoj Kumar Bandaru; Marcel den Hoed; Anastasia Emmanouilidou; Ingelsson Erik; Shannon Fisher; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zebrafish; dyslipidemia; atherosclerosis; genetic screens; high-cholesterol diet; APOE; APOB; LDLR; APOC2; PCSK9; LPAR2; GATAD2A; Medicinsk genetik; Medical Genetics;

   Abstract : Hundreds of loci have been robustly associated with circulating lipids, atherosclerosis and coronary artery disease; but for most loci the causal genes and mechanisms remain uncharacterized. The overall aim of my thesis is to develop and validate novel in vivo model systems that are suitable for high-throughput, image-based genetic screens in coronary artery disease and related traits, and use these model systems to systematically characterize positional candidate genes.

5. 3. Qualitative and Quantitative Assessment of Integration Testing for Model-Based Software in the Automotive Industry

   Author : Jan Schröder; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Case Studies; Software Quality; Validation; Software Metrics; Maintainability; Software Engineering; Empirical Research; Technical Debt;

   Abstract : Background: Integration testing of vehicle software in the automotive industry relies heavily on simulation models. As they replicate actual vehicle functions in the testing process, they increase in size and amount of interconnectivity as rapidly as the actual functions. Valid simulation models are a precondition for valid integration testing. READ MORE

6. 4. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

   Author : Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

7. 5. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

   Author : Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

   Abstract : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. READ MORE
