1. Evaluation of pretension losses in heated screw joint
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. LÄS MER
2. Fabrication and Characterization of Quantum-well Field Effect Transistor
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. LÄS MER
3. Submillimeter 3D surface reconstruction of concrete floors
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.

4. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikSammanfattning : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. LÄS MER
5. Development of a CNC Milling System for Preparation of Micrometer-Sized Samples for X-ray Nanotomography
Master-uppsats, KTH/Tillämpad fysikSammanfattning : X-ray nanotomography is an imaging technique used to study three-dimensional structures at submicrometer length scale. The samples to be studied should be only 10s of micrometers in diameter, and ideally cylindrical. LÄS MER
