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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Naveed ur Rehman Malik; Chandur Sadarangani; Torbjörn Thiringer; [2015]
    Keywords : 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; Energiteknik; Energy Technology;

    Abstract : 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.

  2. 2. Ecological impact of antibiotic treatment on human normal microflora

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Mamun-Ur Rashid; Karolinska Institutet.; Karolinska Institutet.; [2013]

    Abstract : The skin and the mucosal surfaces of humans are colonized with microorganisms which are often referred as the normal microflora. There is a biological balance between the human host and the normal microflora in health. The extensive use of antibiotics in both humans and animals has caused the development of many resistant bacteria. READ MORE

  4. 4. Hygro- and hydroexpansion of paper Influence of fibre-joint formation and fibre sorptivity

    University dissertation from Stockholm : KTH

    Author : Per A. Larsson; Lars Wågberg; Kaarlo Niskanen; [2010]
    Keywords : ;

    Abstract : Paper is a versatile, cheap and environment-friendly material. Nevertheless, there are several factors limiting its usefulness, and one of the major issues is that cellulosic and ligno-cellulosic fibres spontaneously sorb water. At the same time, the water uptake changes the dimensions of the paper. READ MORE
