1. Development of Sensor Concept to Regulate Fuel Supply During Priming of Water to Air Heater in Production
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Water To Air heater (WTA) is a component that heats the interior and the engine of the truck by heating coolant through a combustion of diesel fuel. It is vital that the Water To Air heater is primed with fuel prior to using it in order for it to start when desired. LÄS MER
2. Black phosphorous sample preparation for ultrafast electron diffraction studies
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.

3. In-vivo assessment of unwanted tissue heating during near infrared laser light emission
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : In this work, potential adverse tissue heating in conjunction with near infrared (NIR) laser spectroscopy was studied. The tissue heating from laser light within the NIR optical window is currently a relatively unexplored field. LÄS MER
4. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. LÄS MER
5. Development of Spectroscopic Measurements for Raman and Thomson Scattering Diagnostics ——Applications in Combustion and Plasma
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. LÄS MER
