1. 26. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Gioele Daka; [2023]
   Nyckelord :Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

   Sammanfattning : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. LÄS MER

3. 27. Investigation of MIDEL 7131’s Dielectric Breakdown Strength and Thermal Behaviour : Master Thesis, an experimental study using concentric-like electrodes at elevated temperatures to study breakdowns

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kim Lin; [2023]
   Nyckelord :Dielectric strength; High voltage; Liquid dielectric; MIDEL 7131; Electrical breakdown; Temperature cycle; Dielektrisk styrka; Högspänning; Dielektriska vätskor; MIDEL 7131; Elektrisk nedbrytning; Temperaturcykling;

   Sammanfattning : Dielectric insulation are constantly exposed to various stresses, while also being expected to last for long periods of time. Naturally, they degrade with use and in demanding operational environments, this degradation phenomena can be accelerated, leading to costly consequences. LÄS MER

4. 28. Analysis and simultaion of underfloor heating system for bathrooms in Swedish buildings

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Andreu Fàbregas; [2023]
   Nyckelord :underfloor heating system; insulation; heating loss; energy use; building energy balance; transmission loss;

   Sammanfattning : The pursuit of reducing energy consumption and enhancing thermal efficiency across various sectors to foster sustainable practices has gained significant prominence in recent years, driven by the global environmental crisis. Sweco consultancy has undertaken a study focusing on underfloor heating systems for bathrooms in low-energy buildings located in Sweden. LÄS MER

5. 29. En funktion- och miljöpåverkansanalys av isolerande lättfyllnadsmaterial. : En jämförande studie av cellplast, mineralull, lättklinker, skumglas samt isobetong som isolerande skikt i platta på mark.

   Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Melker Iversen; Josef Lebedev; [2023]
   Nyckelord :Foundation; Thermal insulation; Life Cycle Analysis; Environmental impact; GWP; Slab on ground.; Grundläggning; Värmeisolering; Livscykelanalys; Miljöpåverkan; GWP; Platta på mark.;

   Sammanfattning : This study discusses the current state of climate change, which is causing rising sea levels, increasing temperatures, and threatening ecosystems due to human resource exploitation and carbon emissions. The construction industry is a significant contributor to greenhouse gas emissions, and the study aims to investigate which insulation material is best suited for a ground slab in terms of environmental impact, technical properties, and cost.

7. 30. Optimering av klassrumsmiljön i en ny skolbyggnad i Västerås : En studie om fönsterplacering och energiförluster

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Kunda Fadi; Alhamada Nahla; Celen Mert; [2023]
   Nyckelord :School; design; window; window design; daylight; u-value; thermal bridges; heat losses; energy losses; energy saving.;

   Sammanfattning : Purpose: The purpose of this study was to plan blueprints for a school located Härbregatan and Vallby Skolgata in Västerås with a focus on energy losses and window placement to choose the most suitable types of windows to obtain a good internal environment. Method: The methodology used to conduct this thesis was based on earlier case studies, literature book and literature reviews in the form of legal specification from Boverket Byggregel (BBR) that had a significant impact on how the school was designed, interior and exterior views.
