1. 21. Super-grid Linear Eddy Model (SG-LEM): Efficient mode- and regime-independent combustion closure for Large Eddy Simulation (LES)

   Författare :Abhilash Murlidharan Menon; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; Mapping-closure; Lagrangian splicing; Mesh coarse-graining.; Linear Eddy Model;

   Sammanfattning : Next-generation combustion technology such as ‘lean burn’ and HCCI (Homogeneous Charge Compression Ignition) present new challenges for  combustion modelling. The presence of locally varying combustion modes (premixed vs. non-premixed) and regimes (fast/non-fast chemistry vs. LÄS MER

3. 22. Initiation and early crack growth in VHCF of stainless steels : Experimental and theoretical analysis

   Författare :Muhammad Waqas Tofique; Jens Bergstöm; Nils Hallbäck; Thierry Pallin-Luc; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very High Cycle Fatigue; Stainless steel; Ultrasonic fatigue testing; Crack initiation; Crystallographic crack growth; Distributed Dislocation Dipole Technique; Closed cracks; Materialteknik; Materials Engineering;

   Sammanfattning : Mechanical fatigue is a failure phenomenon that occurs due to repeated application of mechanical loads. Very High Cycle Fatigue (VHCF) is considered as the domain of fatigue life greater than 10 million load cycles. LÄS MER

4. 23. Growth without Democracy : Challenges to Authoritarianism in Vietnam

   Författare :Eva Hansson; Björn Beckman; Olle Törnquist; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; party-state; economic liberalisation; authoritarianism; democratisation; civil society; labour strikes; trade unions and democratisation; industrial zones; Foreign Direct Investment; Vietnam; Political science; Statsvetenskap; Political Science; statsvetenskap;

   Sammanfattning : Vietnam today can clearly be counted as a case of economic success. At a party congress in the mid-1980s, the formal decisions were made on a reform program under the name of Doi Moi (renovation), which aimed at liberalising and reforming the economy. LÄS MER

5. 24. Discursive Decision-making in Meetings of the Global Justice Movements: Cultures and Practices

   Författare :Christoph Haug; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; meetings; social movements; decision-making; deliberation; face-to-face interaction; participant observation;

   Sammanfattning : Based on audio-recordings of 8 and participant observation in about 200 activist meetings in the Global Justice Movements in Europe (especially Attac and the Social Forum process), the thesis addresses two main questions: 1. In what way do the constraints of the meeting-form influence the discussion and hence the decision-making process? 2. LÄS MER

7. 25. Fluid Dynamics of the Bottom Bed of Circulating Fluidized Bed Boilers

   Författare :Anders Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidized beds; circulating fluidized bed boilers; fluctuations; fluidization regimes; bottom bed; bed porosity; fluid dynamics; bubbling beds; circulating fluidized beds; non-slugging; bed expansion; particle concentration;

   Sammanfattning : The fluid dynamic conditions in the furnace of a fluidized bed boiler influence the combustion and the production of harmful emissions. A substantial amount of the bed material in a circulating fluidized bed (CFB) boiler is present as a dense bubbling bottom bed. LÄS MER
