  2. 1. A Collaborative E-learning Approach : Exploring a Peer Assignment Review Process at the University Level in Uganda

    Author : Evelyn Kahiigi Kigozi; Henrik Hansson; Mats Danielson; F. F Tusubira; Mikko Vesisenaho; David Hollow; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : There is an increasing need, driven by the job market, for quality education and that requires expertise which is continuously being developed. The integration of e-learning into the education system is viewed as one way to meet this growing need for high-quality education. READ MORE

  4. 2. Shear and Torsion Interaction in Prestressed Hollow Core Slabs

    Author : Helén Broo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear-torsion capacity; hollow core unit; shear and torsion interaction; non-linear finite element analyses; hollow core slab; precast prestressed concrete; hollow core floor;

    Abstract : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

  5. 3. Hollow Cathode Deposition of Thin Films

    Author : Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
    Keywords : Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

    Abstract : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. READ MORE

  6. 4. Modelling and Applications of the Hollow Cathode Plasma

    Author : Daniel Söderström; Hana Baránková; Ladislav Bárdos; Zoltán Donkó; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; hollow cathode; hybrid plasma; vibrational temperature; atmospheric pressure; fluid modelling; radio frequency; pulsed power; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. READ MORE

  7. 5. Plasma Enhanced Chemical- and Physical- Vapor Depositions Using Hollow Cathodes

    Author : Kaspars Siliņš; Hana Barankova; Ladislav Bardos; Claes Nender; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hollow cathode; TiN; AlN; amorphous carbon; hybrid PVD PE-CVD; ionized magnetron;

    Abstract : Development of coating deposition technologies, in terms of performance and costs, is an ongoing process. A promising class of deposition technologies are based on hollow cathode discharges. READ MORE
