1. 1. Jetbrandtester och vätgas : En litteratur- och intervjustudie om försök med vätgasjetflammor

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Nils Stridsberg; [2024]
   Nyckelord :Hydrogen; jet flames; rescue service; standards; jet fire testing; jet fires; Vätgas; jetflammor; räddningstjänst; standarder; jetbrandtester; jetbränder;

   Sammanfattning : Vätgas är en energibärare som kan vara en av pusselbitarna i omställningen till en mer klimatneutral värld. Infrastrukturen byggs ut, industrin växer och vätgasfordon blir vanligare. LÄS MER

3. 2. Price policy estimation for Demand Response of heat-pump-based loads

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

   Författare :Carlos Eduardo Gil Simancas; [2023]
   Nyckelord :Differential Evolution; Electricity Grids; Flexibility Services; Heat-pumps; Heterogeneous Loads; Implicit Demand Response; Optimization; Differentiell utveckling; elnät; flexibilitetstjänster; heterogena belastningar; implicit efterfrågesvar; optimering; värmepump;

   Sammanfattning : The electricity grids have become a key player in the society. An increased usage of electricity is both a result from the more electrified society, but also as a main solver in reaching the climate goals by reducing emissions. LÄS MER

4. 3. Improved planning of wind farms using dynamic transformer rating

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

   Författare :Andrea Molina Gómez; [2020]
   Nyckelord :Dynamic transformer rating; wind energy; loss of life; mixed-integer linear programming; wind farm planning.; Dynamisk lastbarhet hos transformatorer; vindkraft; livstidsförlust; mixed-integer linear programming; vindkraftsparksplanering;

   Sammanfattning : Due to the increase in electrical demand and renewable penetration, electrical utilities need to improve and optimize the grid infrastructure. Fundamental components in this grid infrastructure are transformers, which are designed conservatively on the base of a static rated power. LÄS MER

5. 4. Optical Payload Mounting Interface Design for a Quantum Key Distribution CubeSat Telescope In-Orbit Demonstration

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Lukas Jakas; [2020]
   Nyckelord :;

   Sammanfattning : Although free-space optical communication systems require to overcome demanding precision requirements for their optical payload, the photonics company mBryonics has taken on the challenge of designing a quantum key distribution telescope for an in-orbit demonstration mission on a CubeSat platform. A part of the task was formulated as a thesis project which is reported in this document. LÄS MER

7. 5. Cracking in a slender concrete slab due to thermal variation

   Master-uppsats, KTH/Betongbyggnad

   Författare :Johan Mattsson; Fredrik Åman; [2019]
   Nyckelord :Concrete slab; Concrete; Finite element analysis; Cracking; Thermal variation; Seasonal temperature; Abaqus; Brigade Plus; Betonggrund; Betong; Finit element analys; Sprickbildning; Termiska laster; Omgivningstemperature; Abaqus; Brigade Plus;

   Sammanfattning : Concrete slabs used in thepulp and paper industries are often situated outdoors, which means that theslabs are exposed to temperature variations due to different weatherconditions. These temperature variations together with operational temperaturesassociated with the manufacturing process, may introduce high temperaturegradients in the concrete. LÄS MER
