6. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratorietSammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER
7. En komparativ analys för beräkningsprogram av U-värde
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Detta arbete har som intention att ge en bra grund för att kunna välja vilket av programmen BISCO eller THERM som är bättre för att beräkna värmegenomgångskoefficienten U, för fönster. Syftet är formulerat utifrån att standarden EN ISO 10077-2:2012 har ersatts med den uppdaterade versionen EN ISO 10077-2:2017 där en stor skillnad är introduktionen till en ny beräkningsmetod.

8. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.
Master-uppsats, Lunds universitet/Industriell ProduktionSammanfattning : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. LÄS MER
9. Forming wide-orbit planets via pebble accretion
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. LÄS MER
10. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. LÄS MER
