  3. 12. An Experimental Study of Fancy Yarn Formation in Rotor Spinning

    Författare :Jan Kwasniak; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : FANCY YARN is a yarn with deliberate imperfections. Strange as it may appear, in present times when defect-free yarn is considered to be a premium product, fancy yarns, with all their imperfections, are also in demand. It is a different matter that the volume production of fancy yarn is insignificant in comparison to the normal yarn production. LÄS MER

    Sammanfattning : Melt Spun Piezoelectric Textile Fibres - an Experimental Study ANJA LUND Department of Materials and Manufacturing Technology Chalmers University of Technology ABSTRACT The manufacturing and characterisation of piezoelectric textile fibres are described in this thesis. A piezoelectric material is one that generates an electric voltage when deformed, a property which exists in a number of materials. LÄS MER

  5. 14. On Some Aspects of Design of Electric Power Ancillary Service Markets

    Författare :Jin Zhong; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spinning reserve; deregulation; electricity market; reactive power; frequency regulation and optimal power flow; ancillary services;

    Sammanfattning : Ancillary services are defined as all those activities on the interconnected grid that are necessary to support the transmission of power while maintaining reliable operation and ensuring the required degree of quality and safety. There are several activities of the operator that come under the preview of ancillary services. LÄS MER

  7. 15. Derivation and BRST Quantization of Models for Spinning Relativistic Particles

    Författare :Ulf Mårtensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with the construction of models for spinning relativistic particles and their covariant quantization within a BRST framework. In the first part the ideas and methods which constitute the background to the papers are reviewed, and a summary of the main results obtained therein is given. The second part consists of the papers. LÄS MER
