  1. 11. Gall induction in gall wasps (Cynipidae s. lat.) : Insights from comparative genomics

    Författare :Erik Gobbo; Fredrik Ronquist; Scott Egan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gall induction; comparative genomics; evolution; selection analysis; microbiome; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Cynipidae are a family of wasps (Hymenoptera), whose larval stages develop inside plant galls, that is, abnormal plant structures formed in response to the presence of foreign organisms. Most cynipids are gall inducers and are often capable of notable levels of host manipulation. LÄS MER

  3. 12. On Fault Detection, Diagnosis and Monitoring for Induction Motors

    Författare :Mohammed Obaid Mustafa; Mohamed El Hachemi Benbouzid; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model based fault detection and diagnosis; Model free fault detection; Set Membership Identification SMI ; Uncertainty Bounds Violation Method; Model based Support Vector Classification; Linear and Nonlinear Classification; Minimum Volume Ellipsoid method; Broken Rotor Bars; Faults of Induction Motors; Three phase induction motor; Reglerteknik; Control Engineering;

    Sammanfattning : In this thesis, multiple methods and different approaches have been established and evaluated successfully, in order to detect and diagnose the faults of induction motors (IMs). The aim of this thesis is to present novel fault detection and isolation methods for the case of induction machines that would have the merit to be implemented online and being characterized by specific novel capabilities, when compared with the existing techniques.

  4. 13. Pharmacodynamics of Enzyme Induction and its Consequences for Substrate Elimination

    Författare :Mats O. Magnusson; Rikard Sandström; Mats Karlsson; Ulf Bredberg; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Enzyme induction; Time course; Turnover model; Mechanism-based; Modelling; NONMEM; Farmakokinetik Farmakoterapi;

    Sammanfattning : Enzyme induction is a process whereby a molecule enhances the expression of enzymes. If the affected enzymes are involved in the elimination of a drug, this may result in a drug interaction. Induction is therefore of major concern during drug development and in clinical practice.

  5. 14. 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.

  7. 15. 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
