1. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging
University essay from Göteborgs universitet / Institutionen för fysikAbstract : 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. READ MORE

2. Implementing Total Electron Content in the Grand Unifed Incoherent Scattering Design and Analysis Program for Investigation of Causes to Scintillations
University essay from Luleå tekniska universitet/RymdteknikAbstract : Functionality for calculating and plotting diferent Total Electron Content (TEC) measurements such as Slant Total Electron Content (sTEC), error in sTEC, and VerticalTotal Electron Content (vTEC) was implemented into the data analysis program fromEuropean Incoherent Scattering Scientifc Association (EISCAT), the Grand Unifed Incoherent Scattering Design and Analysis Program (GUISDAP). This utilises a thin-singlelayer model of the ionosphere to convert sTEC into the more analytically useful vTEC. READ MORE

3. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. READ MORE

4. The Development of a Model for Determining the Spatial Resolution of Pulsed-Neutron Sources
University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning across a one dimensional object of known dimensions.

5. Wave resource assessment using numerical wave modelling
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Wave resource assessment is the collection of site-specific meteorological data to estimate the wave potential in a region and is carried out to mitigate the risks involved in the setup of wave energy converters. Wave resource assessment has been typically done using wave buoys. READ MORE
