1. 1. Ray Tracing Algorithm for Dielectric Domes

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

   Author : Maria Pubill; [2023]
   Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

   Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

3. 2. 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

4. 3. Optimisation of parallel k-d trees using heuristics for neuron touch detection task

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

   Author : Daniel Benedí García; [2022]
   Keywords : ;

   Abstract : Neuroscience has benefited from neuronal network simulation and an important task in the simulation is finding points in space where two neurites approach each other so a synapse could be formed. The task of finding the touching points could be seen as similar to the ray collision in ray tracing in computer graphics. READ MORE

5. 4. Hardware-Accelerated Ray Tracing of Implicit Surfaces : A study of real-time editing and rendering of implicit surfaces

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Herman Hansson Söderlund; [2021]
   Keywords : Implicit Surfaces; Signed Distance Functions; Ray Tracing; Content Creation; Path Tracing; Implicita Ytor; Signed Distance Functions; Strålspårning; Modellering;

   Abstract : Background. Rasterization of triangle geometry has been the dominating rendering technique in the real-time rendering industry for many years. However, triangles are not always easy to work with for content creators. READ MORE

6. 5. Object Selection by Relative Hand to Cursor Mapping : Design and Evaluation of a 2D-Object Selection Technique for Hand Tracking in Virtual Environments

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

   Author : Mikael Dahlgren; [2021]
   Keywords : ;

   Abstract : Hand and tracker jitter negatively affect performance with ray-casting in virtual environments, making it difficult to acquire small objects which require high levels of precision. This study evaluates an alternative target acquisition technique for 2D-interfaces in virtual environments with relative hand-to-cursor mapping. READ MORE
