  2. 2. Hur utvärderas faunapassager? - En litteraturstudie om säkra passager för djur över vägar och hur de utvärderas

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Sara Schrödl; [2018]
    Nyckelord :vägar; habitatfragmentering; barriäreffekt; isolering; viltolyckor; djurpassage; faunapassage; wildlife crossing; utvärdera; användning; förflyttning; beteende; genflöde; genvariation; Population Viability analysis; kamera; spåranalys; telemetri; Passive Integrated Transponder; Earth and Environmental Sciences;

    Sammanfattning : Habitat fragmentation is a common problem in relation with road infrastructure which leads to mortality, isolation of animal populations, and has a negative effect on biodiversity. Animal crossings have been implemented in many countries and are a useful tool to mitigate these problems but they are expensive to build. LÄS MER

  3. 3. 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.

  4. 4. Comparison of Performance and Power Consumption Between GPS and Sigfox Positioning Using Pycom Modules

    Kandidat-uppsats, Högskolan Kristianstad/Avdelningen för datavetenskap; Högskolan Kristianstad/Avdelningen för datavetenskap

    Författare :Xujia Zhou; Eduardo Flora; [2018]
    Nyckelord :Sigfox; GPS; LPWAN; positioning performance; power consumption;

    Sammanfattning : Sigfox is one of the newly-emerging LPWAN (Low Power Wide Area Network) technologies aiming to provide power-efficient solutions to the world of IoT. This study presents a comparison between Sigfox Geolocation and GPS (Global Positioning System) in terms of power consumption and performance which includes three metrics: accuracy and precision, response rate and response time.

  5. 5. Radio based Cooperative Positioning for Vehicle-to-Vehicle Systems in Urban Scenarios

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

    Författare :Hao Wu; [2018]
    Nyckelord :V2V; V2X; CKF; SUMO; GemV2; ns3; algorithm; positioning; urban positioning; non-GPS; Technology and Engineering;

    Sammanfattning : This master thesis aims at improving vehicle positioning in high-speed movement scenarios where global navigation satellite system (GNSS) does not work well. The standard 802. LÄS MER
