  1. 1. Front and rear irradiation distribution for different bifacial PV systems : Simulation and evaluation of the irradiation distribution on the solar PV panels at different albedo conditions using ray-tracing software

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Soufiane El Madi; Shadi Abubaker; [2023]
    Keywords : ;

    Abstract : Bifacial photovoltaic (PV) modules are a type of solar panel that has the capability to capture sunlight and generate electricity from both the front and rear sides of the modules. This work focuses on evaluating the irradiation on both the front and rear sides of bifacial PV modules for various system designs (vertical, tilted, and elevated) and under different ground albedo conditions (grass, snow, and bare soil) using ray-tracing software.

  4. 3. NUDE (APRÈS LE BAIN): An Inter-Disciplinary Technical Study of an Oil Painting on Cardboard by Pierre Bonnard

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Victoria Skalleberg; [2020-08-05]
    Keywords : Bonnard; paper conservation; spectroscopy; material identification;

    Abstract : In this master thesis in paper conservation, an oil painting on cardboard (WL84, Gothenburg Museum of Art) by French artist Pierre Bonnard (1867-1947) is investigated. The painting shows signs of degradation in the form of staining, pigment loss, and discolored varnish. READ MORE

  5. 4. Nötkreaturs betesselektion på vallar baserade på fyra olika fröblandningar

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Patricia Sandberg; [2015]
    Keywords : bete; selektion; beteende; vitklöver; engelskt rajgräs; rörsvingel; nötkreatur; pasture; grazing selection; behaviour; white clover; tall fescue; ray grass; cattle;

    Abstract : En beteendestudie med nötkreatur utfördes under maj-september 2014 på försöksytor sådda i juli 2012 med fyra vallfröblandningar (A-D). Fröblandning A och B innehöll båda 35 % ängsgröe (Poa pratensis), 10 % Rödsvingel (Festuca rubra) och 20 % vitklöver (Trifolium repens) men skilde sig genom att fröblandningen för vall A innehöll 35 % engelskt rajgräs (Lolium perenne) och B innehöll 35 % rörsvingel (Festuca arundinacea).

  6. 5. Cryogenic Etching of the Electroplating Mold for Improved Zone Plate Lenses

    University essay from KTH/Tillämpad fysik

    Author : Daniel Larsson; [2010]
    Keywords : etching; plasma etching; zone plate; x-ray; nanofabrication; sidewall passivation; cryo; cryogenic; undercut;

    Abstract : The fabrication of zone plate lenses that are used for focusing X-rays relies on nanofabrication techniques such as e-beam lithography, reactive ion etching, and electroplating. The circular grating-like zone plate pattern can have a smallest half-period, a so-called zone width, of down to 20 nm while it also needs to have a height that is 5 to 10 times the zone width to have good diffraction efficiency.
