  1. 1. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector

    Master-uppsats, KTH/Marina system

    Författare :Yaolin Ge; [2020]
    Nyckelord :;

    Sammanfattning : Our ocean covers more than 70% of our planet’s surface. It is a huge reservoir continuously supplying us with enormousvaluable resources. The autonomous aquaculture, deep sea mining, subsea oil / gas exploitation and marine biology etc.,are the increasingly important driving forces for the development of underwater robotics. LÄS MER

  2. 2. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Gustav Aaro; [2020]
    Nyckelord :Wi-Fi RTT; Indoor positioning; FTM; Android; Smartphone; Sensor fusion; IPS;

    Sammanfattning : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. LÄS MER

  3. 3. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

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

    Författare :Victor Sesma Santos; Victor Egorov; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. LÄS MER

  4. 4. Wireless wave propagation in city street canyons

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

    Författare :Andrés Felipe Garcia Albarracin; [2017]
    Nyckelord :Channel modeling; Channel sounding; Local scattering function; Ray tracing.; Technology and Engineering;

    Sammanfattning : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.

  5. 5. Movement ecology of the golden eagle Aquila chrysaetos and the semidomesticated reindeer Rangifer tarandus : synchronous movements in a boreal ecosystem

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Mattias Nilsson; [2014]
    Nyckelord :golden eagle; reindeer; GPS transmitter; movement; seasonal migration; ecosystem; Northern Sweden;

    Sammanfattning : The golden eagle Aquila chrysaetos in Sweden are believed to be rather sedentary. Hence, studies in Norway suggest the opposite with a diurnal pattern with seasonal migrations to e.g. south Sweden during the winter – distances of thousands of kilometers. LÄS MER
