2. Simulating metal ct artefacts for ground truth generation in deep learning.
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

3. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

4. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

5. Detection of Emergency Signal in Hearing Aids using Neural Networks
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : ABSTRACT The detection of an emergency signal can be estimated by the cancellation of surrounding noise and achieving the desired signal in order to alert the automobilist. The aim of the thesis is to detect the emergency signal arriving nearer to the automobilist carrying hearing aids. READ MORE
