  1. 1. Aiding Navigation for Groups of Aircraft with Bearing and Distance Measurements

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Mattias Olsson; [2018]
    Nyckelord :Navigational enhancing; consensus filtering;

    Sammanfattning : This thesis extends previous work on navigational aidingof groups of aircraft, primarily intended for the fighter SAAB JAS 39 Gripen,as long as an aircraft gets GPS signals, it is easy to estimate position, but theGPS is relatively easy to jam, rendering alternative methods of positioning necessary.To use internal sensors measuring accelerations and angular velocities is agood replacement on short terms, but gives a drift in positioning over longer timeperiods.

  3. 2. Do Bold Prophecies Lead to Higher Profits?

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Adrian Brun; Carl Oscar Nyh; [2016]
    Nyckelord :Stock recommendations; Sell-side analysts; Herding; Regulation Fair Disclosure;

    Sammanfattning : We find that non-herding ("bold") recommendations - defined as those deviating from last day's consensus by more than one level - had a greater investment value than herding recommendations prior to Regulation Fair Disclosure, which became effective in October, 2000. Indeed, a value-weighted portfolio that purchased S&P 100 companies with the most favourable consensus, made up of bold (all) recommendations, yielded a statistically significant (insignificant) annual abnormal gross return of 7.

  4. 3. Road Surface Modeling using Stereo Vision

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Mattis Lorentzon; Tobias Andersson; [2012]
    Nyckelord :Stereo camera; Digital Elevation map; Temporal filtering; Curb detection; Road surface classification; Random sample consensus; Conditional random fields; Obstacle detection;

    Sammanfattning : Modern day cars are often equipped with a variety of sensors that collect information about the car and its surroundings. The stereo camera is an example of a sensor that in addition to regular images also provides distances to points in its environment. LÄS MER
