1. Antenna measurements of HF antennas using low cost UAVs
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : High-frequency signal far-field measurement systems usually involve the use of complex and expensive equipment, since the measurements must be made at a distance of multiple wavelengths from the antenna. Helicopter surveyors are commonly utilized. LÄS MER
2. Rörelsemönster hos varg i Skandinavien
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Predators have an important role in ecosystems due to their regulating effect on lower trophic levels, but their presence provokes a lot of different opinions and a great deal of interest about their behaviors and movements. It has been observed that predators’ movement patterns and activity patterns can be affected by e.g., human impact (e. LÄS MER
3. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector
Master-uppsats, KTH/Marina systemSammanfattning : 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
4. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : 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
5. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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
