1. 1. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Henry Wittler; [2023-11-29]
   Keywords : ;

   Abstract : 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

3. 2. Investigations and Development in the Area of Automated Security Evaluation of Android Devices with Focus on Bluetooth

   Abstract : Bluetooth is a technology that has been implemented in over 5 billion devices and therefore has a considerable impact. It is the dominant technology for shortrange wireless communication. READ MORE

4. 3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Svante Rosenlind; [2023]
   Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

   Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

5. 4. Citylab: To be or not to be? : A case study of the implementation of Citylab in the municipal urban planning process in Norrtälje and Helsingborg

   University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)
