  1. 1. 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.

  2. 2. 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.

  3. 3. A feasibility study for a satellite VHF Data Exchange System (VDES)

    University essay from KTH/Rymdteknik

    Author : Julian Grujicic; [2019]
    Keywords : Systems engineering; satellite design; satellite communication; AIS; VDES; LEO; satellite constellation; CubeSat; new space .; Systemteknik; satellitdesign; satellitkommunikation; AIS; VDES; Låg-jordbana; satellitkonstellation; CubeSat .;

    Abstract : Transportation across the globe's oceans increases every year and is expected to keep increasing in the following decades. Consequently, there is a need to establish communication over the horizon through the Automatic Identification System (AIS) and the Very High Frequency (VHF) Data Exchange System (VDES), still in development, to track and communicate with vessels all over the globe regardless of the distance from shore.

  4. 4. The Impact of the Difference Signal on the Perceived Loudness of a Piece of Stereo Rock Music : A Comparison Between Headphones and Loudspeakers

    University essay from Luleå tekniska universitet/Institutionen för konst, kommunikation och lärande

    Author : Joel Hansson Lagerberg; [2019]
    Keywords : Loudness; BS.1770; Headphones; Loudspeakers; Stereo; Perception;

    Abstract : The purpose of this study was to evaluate how the BS.1770 Loudness Standard is affected by the amount of difference signal present in the signal being measured, and if this affection is different between the two playback systems Headphones and Loudspeakers. The study was restricted to rock music productions in a stereo format. READ MORE

  5. 5. Spoofing Mitigation Using Multiple GNSS-Receivers

    University essay from Linköpings universitet/Reglerteknik

    Author : Niklas Stenberg; [2019]
    Keywords : GNSS; spoofing; mitigation;

    Abstract : Global Navigation Satellite Systems (GNSS) are used in a multitude of civilian as well as security related applications. GNSS-receivers are vulnerable to different types of spoofing attacks where the receiver is ``tricked'' to provide false position and time estimates. READ MORE
