1. 1. RayTracing Analysis and Simulator Design of Unmanned Aerial Vehicle Communication and Detection System in Urban Environment

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jie Huang; [2022]
   Keywords : Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

   Abstract : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. READ MORE

3. 2. Raytracing in Channel Model Development

   University essay from Karlstads universitet

   Author : Andreas Rogne; [2022]
   Keywords : ;

   Abstract : The fifth generation of mobile internet is upon us, but still, there is work to do before the new technology is fully utilized. The new generation of cellular network promises frequencies ranging from the sub – 6 GHz to 39 GHz, the latter being in the mmWave spectrum. READ MORE

4. 3. Elastic hyperspectral lidar for detecting coherent backscatter from insects

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Lauro Müller; [2022]
   Keywords : Nanosopy; Thin film physics; Hyperspectral; Lidar; Super continuum; Insects; Coherent scattering; Infrared Spectroscopy; Hyperspectral Imaging; Biophotonics; Technology and Engineering;

   Abstract : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.

5. 4. Managing Coherency in Real-TimeRay Tracing

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Fabio Camaiora; [2021]
   Keywords : ;

   Abstract : In recent years, ray tracing’s popularity in real-time rendering wasboosted by the introduction of GPUs which supported hardwareacceleration for ray tracing routines, which sped up the computationtime considerably. In spite of this, ray tracing is still expensive, andas such, most developers enhance their graphical applications with onlyselected raytraced effects, while still relying on rasterization for thecore visual component.

6. 5. A Performance Comparison of Dynamic- and Inline Ray Tracing in DXR : An application in soft shadows

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Author : Joakim Sjöberg; Filip Zachrisson; [2021]
   Keywords : dynamic ray tracing; inline ray tracing; hard shadows; soft shadows; rendering; dynamisk strålspårning; inline strålspårning; hårda skuggor; mjuka skuggor; rendering;

   Abstract : Background. Ray tracing is a tool that can be used to increase the quality of the graphics in games. One application in graphics that ray tracing excels in is generating shadows because ray tracing can simulate how shadows are generated in real life more accurately than rasterization techniques can.
