21. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system
Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER
22. Analysis of degradation of melamine and polyurethane paint systems using different characterization methods. An investigation of automotive paints on trucks
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Sammanfattning på svenska: Billacker är exponerade för solljus och nederbörd under hela lackens livslängd. Lacker behöver motstå faktorer i omgivningen som påverkar nedbrytningen för att leva upp till högt ställda visuella krav. LÄS MER
23. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images
Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationSammanfattning : There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. LÄS MER
24. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/SolcellsteknikSammanfattning : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

25. Design of LED setup for measuring tandem solar cell subcell J-V behaviour
Kandidat-uppsats,Sammanfattning : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. LÄS MER
