1. 1. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

   Author : Lukas Jonasson; [2023]
   Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

   Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

3. 2. Evaluation of Performance and Image Quality for Voxel Cone Tracing

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Johannes Finn; [2022]
   Keywords : computer graphics; voxel cone tracing; voxel-based rendering;

   Abstract : Voxel cone tracing (VCT) is a rendering method designed to approximate global illumination in a fast and efficient way. Global illumination means to render not only the direct lighting of a scene but also light from indirect sources, simulating how light in the real-world tend to bounce around and illuminate even the areas that are occluded from a direct light source.

4. 3. Learning Policies for Path Selection in Attack Graphs

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

   Author : Manuel Rickli; [2022]
   Keywords : ;

   Abstract : IT systems are indispensable nowadays. With thousands of hacking attempts happening daily, cyber defense mechanisms are crucial for maintaining a working state of those systems. Simulating an attacker is a means of preparing for future hacking attacks by determining the most likely vulnerabilities where an attack could be attempted. READ MORE

5. 4. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

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

   Author : Alexander Adolfsson; [2022]
   Keywords : Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

   Abstract : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. READ MORE

6. 5. Geospatial Optimisation Methods for Mini-grid Distribution Networks : MSc Sustainable Energy Engineering (SEE)

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jessica La Costa; [2022]
   Keywords : Energy access; mini-grid; geospatial data; energy modelling; optimisation; Dijkstar; shortest path algorithm; OSeMOSYS; linear programming; distribution layout; low voltage network; python; Jupyter Notebook;

   Abstract : In 2019, 770 million people worldwide lived without electricity. As many as 490 million people could be electrified with 210,000 mini-grids by 2030. Obtaining information for decision-making is crucial to determine the viability of such a project. READ MORE
