1. 1. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

   University essay from Uppsala universitet/Geofysik

   Author : Mussie Habtemariam Zeru; [2024]
   Keywords : Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

   Abstract : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

3. 2. Antenna Arrays for Dual-Frequency Harmonic Radar Application

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

   Author : Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
   Keywords : Technology and Engineering;

   Abstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

4. 3. Improving the experimental setup for ultrasound-optical tomography imaging

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ibtisam Dahir Ahmed; [2023]
   Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

5. 4. Surface Reconstruction using Multipath Propagation in Indoor MIMO Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Elias Olson; Jakob Henningsson; [2023]
   Keywords : Multiple-input multiple-output MIMO radar; multipath recognition; geometry reconstruction; Mathematics and Statistics;

   Abstract : Using active radar for localization in indoor environments is challenging. By signal reflection off walls and other static objects, false targets occur, referred to as multipath "ghosts". These are a significant hinder in interpreting the data. READ MORE

6. 5. 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
