2. 6. Impediments for Automated Software Test Execution

   Author : Kristian Wiklund; Kristina Lundqvist; Daniel Sundmark; Sigrid Eldh; Tanja Vos; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; software engineering; software testing; empirical software engineering; impediments; industrial research; empirical research; test execution; test automation; test execution automation; Computer Science; datavetenskap;

   Abstract : Automated software test execution is a critical part of the modern software development process, where rapid feedback on the product quality is expected. It is of high importance that impediments related to test execution automation are prevented and removed as quickly as possible. READ MORE

4. 7. Ruthenium(II) Polypyridyl Complexes in Supramolecular Systems relevant to Artificial Photosynthesis

   Author : Henriette Wolpher; Björn Åkermark; Licheng Sun; Johannes Vos; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ruthenium complexes; Organic chemistry; Organisk kemi;

   Abstract : This thesis describes the synthesis and properties of ruthenium complexes relevant to artificial photosynthesis. The work includes preparation of RuIIpolypyridine complexes as well as multi component systems where RuII(bpy)3 or RuII(tpy)2 type complexes are used as photosesnsitizers. READ MORE

5. 8. Interacting particles and droplets at low Reynolds numbers

   Author : Lisa Prahl; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; VOS; VOF; Multiphase flow; Interaction; Particles; Droplets; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma;

   Abstract : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. READ MORE

6. 9. Numerical modeling of deforming bubble transport related to cavitating hydraulic turbines

   Author : Daniel Lörstad; Institutionen för energivetenskaper; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Energy research; Energiforskning; Direction Averaged Curvature DAC ; Direction Averaged Normal DAN ; Volume of Solid VOS ; Volume of Fluid VOF ; Lagrangian Particle Tracking LPT ; Large Eddy Simulation LES ; bubble; multiphase; turbulent flows; CFD; hydro-turbine;

   Abstract : Cavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation development.

7. 10. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

   Author : Mikhail Lazarkov; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

   Abstract : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE
