1. 6. Modelling, Analysis, and Control Aspects of a Rotating Power Electronic Brushless Doubly-Fed Induction Generator

   Författare :Naveed ur Rehman Malik; Chandur Sadarangani; Torbjörn Thiringer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brushless doubly-fed induction generator; dual vector control; dynamic model; induction machine; internal model control; Lindmark concept; low-voltage ride-through; passive resistive network; rotating power electronic converter; rotating exciter; symmetrical faults; synchronous machine; thermal model; unity power factor; unsymmetrical faults; vector control; wind turbines.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik;

   Sammanfattning : This thesis deals with the modeling, analysis and control of a novel brushlessgenerator for wind power application. The generator is named as rotatingpower electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G).A great advantage of the RPE-BDFIG is that the slip power recoveryis realized in a brushless manner.

3. 7. Induction heating of carbon fibre reinforced polymer composites : Characterization and modelling

   Författare :Fredrik Lundström; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon fibre reinforced polymers; Induction heating; Material characterization; Thermal properties; Electrical conductivity; Numerical modelling;

   Sammanfattning : Carbon fibre reinforced polymers (CFRP) are lightweight materials with great potential due to their high strength and stiffness relative to their weight. This enables weight reduction in, for example, vehicles, which is important in reducing energy consumption. LÄS MER

4. 8. Interstrand Crosslinks - Induction and repair

   Författare :Daniel Vare; Dag Jenssen; Klaus Erixon; Fredrik Johansson; Marcel Tijsterman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ICL; DNA repair; interstrand crosslink; psoralen; molekylärgenetik; Molecular Genetics;

   Sammanfattning : DNA crosslinking agents exhibit a variety of DNA lesions, such as monoadducts, DNA-DNA interstrand or intrastrand crosslinks or DNA-protein crosslinks. Agents that produce interstrand crosslinks (ICLs) exist naturally and are widely used in chemotherapy. Therefore, it is important to understand how the lesions induced by these agents are repaired.

5. 9. Influence of Fluid Shear on Primary  Nucleation of Organic Compounds in Solution  Jin Liu  Doctoral Thesis

   Författare :Jin Liu; Åke Rasmuson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agitation; Primary nucleation; Induction time; Fluid shear; Energy dissipation; Mass transfer; Molecular alignment; Cluster coalescence; Butyl paraben; Curcumin; m-Hydroxybenzoic acid; Solid-liquid interfacial energy; Nuclei critical radius.; Chemical Engineering; Kemiteknik;

   Sammanfattning : In this work, three experimental systems have been used to study the influence of agitation/ fluid shear on primary nucleation. Three organic compounds have been used with different solvents, i.e. butyl paraben in ethanol solution, curcumin in ethanol solution and m-hydroxybenzoic acid in 1-propanol solution. LÄS MER

7. 10. Pharmacokinetics, drug metabolism and clinical effects of the antimalarial artemisinin : Time-dependencies and modeling aspects

   Författare :Ulrika Sigrid Helena Svensson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; Biofarmaci;

   Sammanfattning : The mechanism behind artemisinin time-dependent bioavailability was investigated using a rat in-situ single-pass jejunal perfusion technique. The consequence for drug combination therapy was studied in healthy volunteers and in patients with Plasmodium falciparum. LÄS MER
