  1. 1. DRONAR: Obstacle echolocation using ego-noise

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Henrik Nilsson; [2023]
    Keywords : Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

    Abstract : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. READ MORE

  3. 2. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Caroline Morin; [2023]
    Keywords : Optical remote sensing; Sentinel 2; Phosphorus; Total suspended matter; Turbidity;

    Abstract : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. READ MORE

  4. 3. Simulation and Testing of a MU-MIMO Beamforming System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Keywords : Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Abstract : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. READ MORE

  5. 4. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Shenelle Agard; [2023]
    Keywords : tailings storage facility; critical raw materials; machine learning; mine valorisation;

    Abstract : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. READ MORE

  6. 5. Test and Calibration of CUBES: a CubeSat X-ray Detector

    University essay from KTH/Fysik

    Author : Caroline Holmberg; [2022]
    Keywords : Applied Physics; Astroparticle Physics; Tillämpad fysik; Astropartikelfysik;

    Abstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE
