1. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects
University essay from Uppsala universitet/MaterialteoriAbstract : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. READ MORE

2. Analysis of wall-mounted hot-wire probes
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

3. Analysis of Cooling System and Its Influence on Magnetic Flux Density in a Motor
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : After Michael Faraday invented the magnetism theory in 1821, the application of the permanent magnet machine was rapidly developed. The permanent magnet synchronous machine is one of the popular applications of electromagnetic theory, which is implemented in most electric vehicles nowadays. READ MORE

4. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics
University essay from KTH/MaterialvetenskapAbstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE

5. Near-local density approximation approach to one-dimensional lattice systems
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : Describing many-body quantum systems has been an analytically and computationally challenging task since the advent of quantum mechanics. However, in the past 50 years as a result of our technological advancement and the emergence of methods such as density-functional theory (DFT), we have taken crucial steps forward regarding our ability to study and understand large quantum systems.
