  1. 1. Simulating ADS-B and CPDLC messages with SDR

    University essay from Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

    Author : Hanna Gustafsson; Sofie Eskilsson; [2020]
    Keywords : ADS-B; CPDLC; SDR;

    Abstract : Several studies have shown insufficient security in air traffic communication. The increase in air traffic in recent years also increases the need for improved security. CPDLC is used to communicate in text over the data link and ADS-B determines the position of an aircraft. These techniques are looked upon and simulated in the thesis. READ MORE

  2. 2. HDR and the Colorist : How new technology affects professionals in the motion picture industry

    University essay from Högskolan Dalarna/Ljud- och musikproduktion

    Author : Jonas Westling; [2019]
    Keywords : HDR; High Dynamic Range; Colorist; Color correction; Color grading; Cinema; Motion picture; Digital video; Film; Postproduction;

    Abstract : By utilizing a Research through Design approach this master thesis studies how technological changes might affect professionals working in the motion picture industry, specifically; how the advent of HDR (High Dynamic Range) affects the colorist. The research questions formulated are the following; (1) How can color grading in HDR be approached? (2) What effect can HDR have on visual modality? (3) What specific affordances can HDR offer the colorist? (4) How can HDR affect the creative space of the colorist? Three of the research questions are derived from the theoretical framework applied in this master thesis; starting with the social semiotic implementation of the term modality (models of reality), the Gibsonian term affordance (possibilities for action and meaning making) and its use in communications research, and lastly; the concept of creative space in motion picture production.

  3. 3. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Richard Hedlund; [2019]
    Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.
