1. 6. Interruptible Load Services in Deregulated Power Market

   Författare :Anh Tuan Le; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion management; deregulated electricity market; ancillary services; optimal power flow; reserve generation; interruptible load management;

   Sammanfattning : Since the nineties decade, many electric utilities world-wide have been under restructuring from vertically integrated functioning to deregulated open-market system. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole.

3. 7. Load-Carrying Capacity of Damaged Concrete Structures

   Författare :Kamyab Zandi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frost; bond properties; material properties.; Existing concrete structures; load-carrying capacity; corrosion of reinforcement;

   Sammanfattning : AbstractA growing need for better assessment of existing structures has revealed the need for improved understanding of structural effects of deterioration. The two most common causes of deterioration in concrete structures are corrosion of reinforcement and freezing of concrete. LÄS MER

4. 8. On the treatment of tibial fractures using the Ilizarov fixator

   Författare :Telmo Oliveira Ramos; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tibial fracture; external fixation; load; EQ-5D; NHP; VAS; intramedullary nail; gait analysis; randomised study;

   Sammanfattning : The aim of this thesis was to analyse the results of the Ilizarov method in patients with different types of tibial fracture and compare them with conventional methods, in terms of primary union, complication rates, post-operative function, quality of life, and how the patients´ gait was affected during rehabilitation. Fifty-eight patients with isolated diaphyseal fractures (Study I) were randomised to treatment with either the Ilizarov method (IL) or locked intramedullary nailing (IM). LÄS MER

7. 10. Reduction of heat transfer and heat load in internal combustion engines

   Författare :Joop Somhorst; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; TBC; thermal barrier coating; surface roughness; engine; heat transfer; emissions; alumina; zirconia;

   Sammanfattning : Thermal insulation of the combustion chamber in an engine has great potential to reduce fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. LÄS MER
