11. Soil profile analysis by vibration theory and the natural frequency : Applied on a case project
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/GeoteknologiSammanfattning : To explore soil conditions at sites of infrastructure projects a number of geotechnical soundings are performed at appropriate intervals. Results are, in the nature of their set up, limited to the specific points at which the sounding is performed. LÄS MER
12. A Fourier approach to valuating derivative assets
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : This paper valuates two different financial contracts, the European Call and the Spread option using the Fourier transform. In the European Call case the underlying asset is modelled by the geometric Brownian motion stochastic differential equation. LÄS MER
13. Data acquisition system for optical frequency comb spectroscopy
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : The Optical Frequency Comb Spectroscopy (OFCS) Group at the Department of Physics at Umeå University develops new techniques for extremely high sensitivity trace gas detection, non invasive temperature measurements, and other applications of OFCS. Their setup used primarily for trace gas detection contains several components that have been developed in-house, including a Fourier Transform Spectrometer (FTS) and an auto-balancing detector.

14. AERODYNAMIC FORCING & DAMPING COMPUTATIONS IN A TRANSONIC AXIAL TURBINE OF A TURBOCHANRGER USING TIME & FREQUENCY DOMAIN FLOW TRANSFORMATION TECHNIQUES
Master-uppsats, KTH/EnergiteknikSammanfattning : The current report discusses efficient and accurate numerical techniques to evaluate aerodynamic disturbance and damping forces based on investigations carried out at ABB Turbo System AG. The test turbomachine comprises a single-stage transonic axial turbine analysed with the fluid dynamic software ANSYS CFX 17.0 and post-processing tool Matlab. LÄS MER
15. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H
Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.
