1. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies
Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. LÄS MER
2. Effekt av fasändringsmaterial på hydratiseringprocessen hos Portlandcement: En experimentell studie
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : The Phase change materials (PCM) have the ability to absorb and release heat as the temperature changes from high to low temperature and vice versa. The use of phase change materials has increased in the construction sector due to the established environmental requirements and the various application benefits, especially in the thermal comfort of building applications and construction of sustainable infrastructure around the world (Berardi and Gallardo, 2019).

3. Best practice of extracting magnetocaloric properties in magnetic simulations
Master-uppsats, Uppsala universitet/MaterialteoriSammanfattning : In this thesis, a numerical study of simulating and computing the magnetocaloric properties of magnetic materials is presented. The main objective was to deduce the optimal procedure to obtain the isothermal change in entropy of magnetic systems, by evaluating two different formulas of entropy extraction, one relying on the magnetization of the material and the other on the magnet's heat capacity.

4. EVALUATING THE ORGANIC RANKINE CYCLE (ORC) FOR HEAT TO POWER : Feasibility and parameter identification of the ORC cycle at different working fluid with district waste heat as a main source.
M1-uppsats, Mälardalens högskola/Framtidens energiSammanfattning : New technologies to converting heat into usable energy are constantly being developed for renewable use. This means that more interactions between different energy grid will be applied, such as utilizing low thermal waste heat to convert its energy to electricity. LÄS MER
5. Magnetic Properites in Alloy Systems
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/MaterialvetenskapSammanfattning : The attention for materials displaying high magnetocaloric effect (MCE) has grown during the past 30 years. One of the most important properties of MCE is the adiabatic temperature change ( ). The main aim of this work was to develop a method to measure the temperature change ( ) for magnetocaloric materials in a changing magnetic field. LÄS MER
