  1. 21. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  3. 22. Electromagnetic Compatibility (EMC) test in an Open Area

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Nair Samira; [2023]
    Nyckelord :EMC; EMC Aircraft; EMC Spacecraft; EMC standard;

    Sammanfattning : Electromagnetic compatibility (EMC) is a very important and increasingly relevant technology in use and is closely related to many technologies such as automobiles and aerospace industry technology including aircraft and spacecraft. Achieving electromagnetic compatibility between equipment inside the device is more than necessary to avoid the problem of interference leading to serious problems. LÄS MER

  4. 23. Monitoring of Partial Discharges on Cable Terminations : An experimental approach to evaluate non-conventional online PD measurement techniques

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tony Sibo; [2023]
    Nyckelord :Monitoring; Partial discharges; Medium-voltage cable terminations; Sensor performance; Reliability evaluation; Infrared camera IR-camera ; Ultrasonic emission sensor AE-sensor ; Temperature and relative humidity sensor TRH-sensor ; High frequency current transformer HFCT ; Transient earth voltage antenna TEV-antenna ; Conventional VS non-conventional PD measurement techniques; Övervakning; Partiella urladdningar; Mellanspänningskabelslut; Evaluering av sensorprestanda; Utvärdering av systemets tillförlitlighet; Infraröd kamera; Ultraljudssensor; Temperatur- och relativ fuktighetssensor; Högfrekvent strömtransformator; Transient jordspänningsantenn; Konventionella vs icke-konventionella mättekniker;

    Sammanfattning : The transmission of electric power over long distances has historically posed challenges. However, the advent of high-voltage engineering has not only addressed distance barriers and power losses in electricity transmission and distribution, but it has also significantly improved the efficiency and transmission capacity of power grids.

  5. 24. Exploring the nexus between law enforcement strategies and the increased feelings of insecurity among citizens in Östra Göinge municipality - The functions and dysfunctions of the law

    Master-uppsats, Lunds universitet/Rättssociologiska institutionen

    Författare :Agron Selaci; [2023]
    Nyckelord :Municipality; law; police; practices; functions; dysfunctions; insecurity; migration; integration; Social Sciences;

    Sammanfattning : While the Swedish Police, in the geographical area in which they operate, as well as each municipality in Sweden, are responsible for making their residents feel secure, this thesis examines the causes behind the increased feelings of insecurity among residents in Östra Göinge municipality. The main purpose of this study is to investigate the link between the practices of the local police in Östra Göinge and Östra Göinge municipality, which are governed by legal directives, and the increased feelings of insecurity among residents in Östra Göinge municipality.

  7. 25. Estimation of respiratory frequency from Heart Rate Variability

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Ågärd; [2023]
    Nyckelord :time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER
