  1. 16. Photonic devices with MQW active material and waveguide gratings : modelling and characterisation

    Author : Nadeem Akram; Lars Thylén; Hartmut Hillmer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Method of Lines; Grating; ARROW Waveguide; Semiconductor laser; quantum well; Photonics; Fotonik;

    Abstract : The research work presented in this thesis deals with modelling, design and characterisation of passive and active optical waveguide devices. The rst part of the thesis is related to algorithm development and numerical modelling of planar optical waveguides and gratings using the Method of Lines (MoL). READ MORE

  2. 17. On the dynamics of an hydropower generator subjected to unbalanced magnetic pull : characterisation and analysis

    Author : Yogeshwarsing Calleecharan; Rolf Gustavsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Eccentricity leading to unbalanced magnetic pull (UMP) in rotating electrical machines is a significant concern in industry. The UMP arises due to magnetic flux crossing the air-gap between the rotor and stator, and can be more intense than the useful peripheral force that the machine develops. READ MORE

  3. 18. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Author : Daniel Wiklund; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel sheet; tribology; surface topography; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  4. 19. Characterisation of Chromatography Media Aimed for Purification of Biomolecules

    Author : Mikael Andersson; Bergquist Jonas; Bo-Lennart Johansson; Jan-Christer Janson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Media; Characterisation; Stability; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Abstract : Chromatography media (resins) are very important for and widely used by the biopharma industry in large scale production of biopharmaceuticals, e.g. monoclonal antibodies. Today there are several hundred biopharmaceuticals released globally on the healthcare market. READ MORE
