1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER
2. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging
Master-uppsats, Göteborgs universitet / Institutionen för fysikSammanfattning : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. LÄS MER
3. Digital Front End Algorithms for Sub-Band Full Duplex
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

4. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER
5. Magnetic field of the magnetic chemically peculiar star V1148 Ori
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. LÄS MER
