1. 1. A Stochastic Control Approach to Include Transfer Limits in Power System Operation

   Författare :Magnus Perninge; Lennart Söder; Christopher DeMarco; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; power regulating market; power system operation; power system security; stochastic impulse control; transfer capacity; transfer limit;

   Sammanfattning : The main function of the power grid is to transfer electric energy from generating facilities to consumers. To have a reliable and economical supply of electricity, large amounts of electric energy often have to be transferred over long distances. LÄS MER

3. 2. Understanding the mechanisms behind atom transfer radical polymerization : exploring the limit of control

   Författare :Helena Bergenudd; Mats Jonsson; Eva Malmström Jonsson; David M Haddleton; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymerization; controlled radical polymerization; atom transfer radical polymerization; kinetics; catalysis; electrochemistry; Polymer chemistry; Polymerkemi;

   Sammanfattning : Atom transfer radical polymerization (ATRP) is one of the most commonly employed techniques for controlled radical polymerization. ATRP has great potential for the development of new materials due to the ability to control molecular weight and polymer architecture. LÄS MER

4. 3. Retroviral gene transfer to repopulating hematopoietic cells

   Författare :Thomas Relander; Tumörmikromiljö; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GLVR-1; VSV-G; amphotropic; GALV; long-term bone marrow culture; NOD SCID; retroviral vector; hematopoietic stem cells; stem cells; gene transfer; gene therapy; fibronectin; Clinical genetics; Klinisk genetik;

   Sammanfattning : Hematopoietic stem cells (HSCs) have the capacity to maintain hematopoiesis throughout life. HSCs are ideal targets for permanent gene transfer, as the transgene will be expressed in all the progeny of the gene-modified stem cells. LÄS MER

5. 4. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

   Författare :Akira Yamauchi; KTH; []
   Nyckelord :Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

   Sammanfattning : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. LÄS MER

7. 5. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers

   Författare :Sadegh Seddighi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Capture and Storage; Combustion; Circulating Fluidized Bed; Oxy-Fuel; Multi-Phase Reacting Flow; Boiler Design; Emission; Fluid Dynamics; Heat Transfer;

   Sammanfattning : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.
