  1. 1. Real-time Human Detection using Convolutional Neural Networks with FMCW RADAR RGB data

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

    Author : Anna Phan; Rogelio Medina; [2022]
    Keywords : Human Detection; Machine Learning; Convolutional Neural Networks; YOLO; FMCW Radar; Human Detection Evaluation; Människodetektering; Maskininlärning; Neurala faltningsnät; Djupa faltningsnät; YOLO; FMCW Radar; Utvärdering;

    Abstract : Machine learning has been employed in the automotive industry together with cameras to detect objects in surround sensing technology. You Only Look Once is a state-of-the-art object detection algorithm especially suitable for real-time applications due to its speed and relatively high accuracy compared to competing methods.

  2. 2. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

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

    Author : Axel Enquist; [2022]
    Keywords : MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

    Abstract : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.

  3. 3. The magnetic field of phi Draconis

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Nikolaos Papakonstantinou; [2022]
    Keywords : stars: atmospheres – stars: chemically peculiar – stars: magnetic field – stars: starspots – stars: individual: phi Dra;

    Abstract : Within this past decade, advances in spectropolarimetric analyses allowed mapping surface characteristics of nearby non-resolved stars with unique characteristics. In this study, we attempt mapping of the magnetic field structure and surface distribution of elements for such a star, the magnetic Ap star phi Dra. READ MORE

  4. 4. Laser cooling, state initialization and laser manipulation of a trapped ion

    University essay from Stockholms universitet/Fysikum

    Author : Julius Andersson; [2021]
    Keywords : Ion trap; Quantum computer;

    Abstract : One way of realizing a quantum computer is to use an ion trap. The research group Trapped Ion Quantum Technologies at Stockholm university were operating an ion trap with strontium ions. To increase the coherence time they installed a magnetic field shielding. Therefore the experimental setup had to be partially rebuilt. READ MORE

  5. 5. Optimisation of line of sight matching to obtain wind vectors from the SIW satellite

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Theresia Hestad; [2021]
    Keywords : Remote sensing; Wind measurements; Middle atmosphere; Retrieval; Scan bias; Satellite;

    Abstract : SIW, Stratospheric Inferred Winds, is one of the upcoming Swedish research satellites, aiming to study the winds in the middle atmosphere by measuring the Doppler shifts in molecules such as O3 with a limb viewing sub-mm spectrometer. By conducting simulations on the expected observations, the pointing sensitivity requirement of the satellite was investigated to be able to optimise the matching of the wind vectors. READ MORE
