1. 11. Flexible culverts in sloping terrain : Research advances and application

   Författare :Amer Wadi; Raid Karoumi; Lars Pettersson; Jan Vaslestad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Slope stability; Avalanche load; Snowshed; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Although the construction of flexible culverts involves simplicity in comparison to similar concrete structures, the complexity of the beneficial interaction between soil and steel materials requires good understanding for their composite action and performance. Current design methods have certain validity limitations with regard to applicable slopes above the structures. LÄS MER

3. 12. Customization for an Energy-Efficient Embedded Processor with Flexible Datapath

   Författare :Tung Hoang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integration.; Embedded; Multiply-ACcumulate; Flexible; Energy;

   Sammanfattning : Due to diversified demands of customers, embedded processor datapaths have been extended to accept many functional units, thus growing more complex and energy inefficient. For this reason, it is necessary to carefully analyze the characteristics of the specific embedded applications and fine-tune the hardware implementation. LÄS MER

5. 14. Self-adaptable catalysts : Importance of flexibility and applications in asymmetric catalysis

   Författare :Ester Fjellander; Christina Moberg; Jay Siegel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptable; flexible; semi-flexible; symmetry; conformational study; mechanistic study; rotation barrier; VT NMR; asymmetric catalysis; ligand design; allylic alkylation; hydrogenation; azepines; dioxaphosphepines; phosphepines; amines; phosphines; phosphoramidites; phosphinites; palladium; rhodium; Organic chemistry; Organisk kemi;

   Sammanfattning : The topic of this thesis is the design and synthesis of biaryl-based self adaptableligands for asymmetric metal catalysis. The results discussed in papers I-III are covered, together with some unpublished results concerning substrate-adaptable catalysts. A general survey of self-adaptable catalysts is presented first.
