1. 1. ISAR Imaging Enhancement Without High-Resolution Ground Truth

   University essay from Linköpings universitet/Datorseende

   Author : Moltas Enåkander; [2023]
   Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

   Abstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE

3. 2. The Higgs Width in Higgs production in association with a W+ boson

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Wijeratne Mohandiramge Umashi Navisha Fernando; [2023]
   Keywords : Higgs boson; Higgs width; off-shell; on-shell; narrow-width approximation; MadGraph5_MC@NLO; W boson; supersymmetry; dark matter; Physics and Astronomy;

   Abstract : The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. READ MORE

4. 3. Saturated planar laser-induced fluorescence using sinusoidal intensity modulation

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Klara Lozani Gerdhem; [2023]
   Keywords : fluorescence; fluorophore; LIF; PLIF; saturated LIF; saturated PLIF; structured light; Physics and Astronomy;

   Abstract : Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. READ MORE

5. 4. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
   Keywords : HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

   Abstract : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

6. 5. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

   University essay from Mälardalens högskola/Framtidens energi

   Author : Emil Skoglund; [2021]
   Keywords : PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

   Abstract : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. READ MORE
