1. 1. Staten som marknadens salt : en studie i institutionsbildning, kollektivt handlande och tidig välfärdspolitik på en strategisk varumarknad i övergången mellan merkantilism och liberalism 1720-1862

   Författare :Stefan Carlén; Karl Gunnar Persson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; collective action; evolutionary economics; government; history; institututional change; interest groups; mercantilism; pre-industrial welfare policies; salt; state; storage;

   Sammanfattning : This dissertation studies public institutional arrangements on the Swedish salt market 1720-1862. Crucial issues are how an why these arrangements emerged and were changed as well as they were used. The arrangements were erected in order to realize economic and social goals. LÄS MER

3. 2. Human-Robot Collaboration for Kinesthetic Teaching

   Författare :Julian Salt Ducaju; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Human-Robot Collaboration; Kinesthetic Teaching; Collaborative Robots;

   Sammanfattning : Recent industrial interest in producing smaller volumes of products in shorter time frames, in contrast to mass production in previous decades, motivated the introduction of human–robot collaboration (HRC) in industrial settings, as an attempt to increase flexibility in manufacturing applications by incorporating human intelligence and dexterity to these processes. This thesis presents methods for improving the involvement of human operators in industrial settings where robots are present, with a particular focus on kinesthetic teaching, i. LÄS MER

4. 3. Modeling internal deformation of salt structures targeted for radioactive waste disposal

   Författare :Zurab Chemia; Hemin Koyi; Harro Schmeling; Ian Alsop; Uppsala universitet; []
   Nyckelord :salt; diapir; anhydrite; deformation; entrainment; numerical modeling; rheology; sinking; Gorleben;

   Sammanfattning : This thesis uses results of systematic numerical models to argue that externally inactive salt structures, which are potential targets for radioactive waste disposal, might be internally active due to the presence of dense layers or blocks within a salt layer.The three papers that support this thesis use the Gorleben salt diapir (NW Germany), which was targeted as a future final repository for high-grade radioactive waste, as a general guideline.

5. 4. Mechanisms of salt frost scaling on portland cement-bound materials: studies and hypothesis

   Författare :Sture Lindmark; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deterioration; Durability; Freeze-Thaw; Frost; Salt; Mechanism; Chloride; Diffusion; Adsorption; Building construction; Cement; Concrete; Byggnadsteknik;

   Sammanfattning : A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. LÄS MER

7. 5. Neutronics in Molten Salt Reactors

   Författare :Anders Jonsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; two-group theory; Molten Salt Reactors; neutron noise;

   Sammanfattning : This thesis contains two studies of the MSR properties. The firstuses one-group theory and data that correspond to a traditionaluranium fuelled light water reactor to investigate the basis physicaldifferences that might arise duesolely to the movement of the fuel. LÄS MER
