1. Limited angle reconstruction for 2D CT based on machine learning
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

2. Approach for frequency response-calibration for microphone arrays
University essay from KTH/Hälsoinformatik och logistikAbstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : 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

4. FPGA Implementation of an Anonymization Algorithm
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : With the large amount of surveillance cameras in our public spaces there has been much discussion about their effects on privacy. Axis communications has an algorithm that tries to remedy this by making it hard to see who is in an image but still have it possible for a neural network to detect that there is a person present.

5. Parking Map Generation and Tracking Using Radar : Adaptive Inverse Sensor Model
University essay from Linköpings universitet/Fluida och mekatroniska systemAbstract : Radar map generation using binary Bayes filter or what is commonly known as Inverse Sensor Model; which translates the sensor measurements into grid cells occupancy estimation, is a classical problem in different fields. In this work, the focus will be on development of Inverse Sensor Model for parking space using 77 GHz FMCW (Frequency Modulated Continuous Wave) automotive radar, that can handle different environment geometrical complexity in a parking space.
