  1. 1. Modeling and Analysis of PMSM with Turn-To-Turn Fault

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Joachim Härsjö; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic forces; vibration.; inter-turn; fault; fault detection; turn-to-turn fault; Permanent magnet synchronous machine PMSM modeling;

    Abstract : Thanks to its high-torque density and high efficiency, the Permanent Magnet Synchronous Machine (PMSM) is today used in a vast range of applications, spanning from automotive to wind. Since in a PMSM the excitation field is provided by a permanent magnet instead of a coil, this machine does not have a rotor circuit and thereby the risk for electrical failures can be isolated on the stator circuit.

  2. 2. Turn-taking and early phonology Contingency in parent-child interaction and assessment of early speech production

    University dissertation from Stockholm : Department of Linguistics, Stockholm University

    Author : Ulrika Marklund; Stockholms universitet.; [2018]
    Keywords : HUMANIORA; HUMANITIES; parent-child interaction; turn-taking; parental responsiveness; phonological development; phonological complexity; assessment of speech production; Phonetics; fonetik;

    Abstract : This thesis focuses on contingency in parent-child interaction, investigating it in the light of the linguistic capacity of the child and the status of the caregiver. Further, the thesis covers the development of two tools to assess the developmental maturity level of expressive phonology. READ MORE

  3. 3. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

    University dissertation from Stockholm : Department of Linguistics, Stockholm University

    Author : Joachim Härsjö; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

    Abstract : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. READ MORE

  4. 4. Design and synthesis of -turn peptidomimetics Applications to angiotensin II

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Susanna Lindman; Uppsala universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; peptide synthesis; turn mimetics; molecular modelling; receptor binding affinity; Farmaceutisk kemi; PHARMACY Pharmaceutical chemistry; FARMACI Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Abstract : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. READ MORE

  5. 5. Design and Synthesis of AT2 Receptor Selective Angiotensin II Analogues Encompassing β- and γ-Turn Mimetics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ulrika Rosenström; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Angiotensin II; AT2; AT1; Benzodiazepine; Peptidomimetics; γ-turn; β-turn; Farmaceutisk kemi; PHARMACY Pharmaceutical chemistry; FARMACI Farmaceutisk kemi;

    Abstract : Important information on the bioactive conformation of biologically active peptides may be obtained by studies of rigid peptides or well-defined secondary structure mimetics incorporated into pseudopeptides. The structural requirements for the interaction of angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe) with its AT1 and AT2 receptors were the subject of this study. READ MORE
