11. Deep Learning-based Regularizers for Cone Beam Computed Tomography Reconstruction
Master-uppsats, KTH/Matematisk statistikSammanfattning : Cone Beam Computed Tomography is a technology to visualize the 3D interior anatomy of a patient. It is important for image-guided radiation therapy in cancer treatment. During a scan, iterative methods are often used for the image reconstruction step. LÄS MER
12. Performance Evaluation of LoRa networks for Air-to-Ground Communications
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The current focus on the Internet of Things (IoT) has led to the emergence of many network scenarios with unlimited use cases, including smart homes, smart cities, smart agriculture, and more. Unmanned aerial vehicles (UAVs), also known as drones, have become increasingly popular due to their versatility and ability to collect and transmit data through various sensors and cameras. LÄS MER
13. Photoluminescence Mapping of Erbium Doped Lithium Niobate
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

14. Estimation of respiratory frequency from Heart Rate Variability
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER
15. Aurora-Imaging UAV Cameras
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Ground based optical observations are limited by weather. One of the possible solutions is using adrone to fly above the clouds. This enables new approaches when planning experiments. The aim ofthis project is to produce and evaluate prototypes of aurora-imaging cameras that will be placed insideof such a drone. LÄS MER
