  1. 1. Radon, radar och representationsteori

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Mattias Byléhn; Rahim Nkunzimana; [2019-07-02]
    Nyckelord :;

    Sammanfattning : Detta arbete behandlar grunderna i harmonisk analys på sfären S2 och den reducerade HeisenberggruppenH1. Vi presenterar grundläggande terminologi för unitära representationer ochvisar hur man kan utvidga grundläggande koncept från Fourieranalys till sfären och Heisenberggruppen. LÄS MER

  2. 2. Deinterleaving pulse trains with DBSCAN and FART

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Shad Mahmod; [2019]
    Nyckelord :DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

    Sammanfattning : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. LÄS MER

  3. 3. On the statistics and practical application of the reassignment method for Gabor spectrograms

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Erik. M Månsson; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. LÄS MER

  4. 4. What meets the eye : Naturalistic observations of air traffic controllers eye-movements during arrivals using eye-tracking

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Viktor Lind-Hård; [2019]
    Nyckelord :Cognitive science; Air Traffic Controller; Eyetracking;

    Sammanfattning : How do air traffic controllers, or ATCos, distribute visual attention and can it vary between controllers? In this study, using primarily eye-tracking data and a couple of on-site interviews, these questions are explored. Two ATCos, with the most similar landings, had their eye-movements recorded with Tobii pro glasses 2 and further analysed by categorizing every fixation into different areas of interest during four landings.

  5. 5. Differential Millimetre Wave On-Chip Inductors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Francisco Gonzalez Manero; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The increasingly interconnected world requires systems that support high data rates, and thus the development of mm-wave systems is necessary. Automotive collision radar (80 GHz) or WLANs (60 GHz) are one of the applications that led the increment of the demand in RFICs, in which monolithic devices are fundamental, such as on-chip inductors or transformers.
