  1. 1. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Ivan Rashid; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. LÄS MER

  3. 2. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Erica Svensson; [2022]
    Nyckelord :Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

    Sammanfattning : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. LÄS MER

  4. 3. Airborne Angle-Only Geolocalization

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tove Kallin; [2021]
    Nyckelord :Angle-only; Bearing-only; Bearing; Geolocalization; Localization; Jammers; NLS; EKF; UKF; Cramér-Rao Lower Bound; Terrain; Elevation Data;

    Sammanfattning : Airborne angle-only geolocalization is the localization of objects on ground level from airborne vehicles (AV) using bearing measurements, namely azimuth and elevation. This thesis aims to introduce elevation data of the terrain to the airborne angle-only geolocalization problem and to demonstrate that it could be applicable for localization of jammers. LÄS MER

  5. 4. Analysis of an Ill-posed Problem of Estimating the Trend Derivative Using Maximum Likelihood Estimation and the Cramér-Rao Lower Bound

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Muhammad Farhan Naeem; [2020]
    Nyckelord :carbon dioxide levels; Keeling Curve; Taylor and Fourier series; Maximum Likelihood Estimation; MLE; Cramér-Rao Lower Bound; CRLB;

    Sammanfattning : The amount of carbon dioxide in the Earth’s atmosphere has significantly increased in the last few decades as compared to the last 80,000 years approximately. The increase in carbon dioxide levels are affecting the temperature and therefore need to be understood better. LÄS MER

  7. 5. Deployment Strategies for High Accuracy and Availability Indoor Positioning with 5G

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Jesper Ahlander; Maria Posluk; [2020]
    Nyckelord :Indoor positioning; 5G; Cramér-Rao Lower Bound; Time Difference Of Arrival; Round Trip Time; Geometric Dilution Of Precision; Availability; Accuracy; Deployment strategies; Line-Of-Sight; Interference;

    Sammanfattning : Indoor positioning is desired in many areas for various reasons, such as positioning products in industrial environments, hospital equipment or firefighters inside a building on fire. One even tougher situation where indoor positioning can be useful is locating a specific object on a shelf in a commercial setting. LÄS MER
