  1. 1. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE

  2. 2. Evaluating LoRaWAN for IoT applications by developing a wireless parking space monitoring sensor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Felix Jontegen; Emma Good; [2018]
    Keywords : LoRaWAN; IoT; Parking space monitoring; Car detection; The Things Network; LoRaWAN; IoT; Parkeringsplatsbevakare; Bildetektering; The Things Network;

    Abstract : The process of finding a parking space can be a tedious task that drivers spent too much time on today. With the rising threat from global warming, reducing the time spent driving is vital. READ MORE

  3. 3. 5G Positioning using Machine Learning

    University essay from Linköpings universitet/Reglerteknik

    Author : Magnus Malmström; [2018]
    Keywords : 5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Abstract : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

  4. 4. Nya metoder för att detektera AhR-aktivitet i fiskceller

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Linnea Eknefelt; [2018]
    Keywords : Arylhydrokarbonreceptor; AhR; akvatisk toxicitet; zebrafiskceller; ZFL; ZF4; TCDD;

    Abstract : Toxicitetstester på bland annat fisk är ett viktigt verktyg för att samla kunskap om kemikaliers effekter i akvatiska miljöer. Samtidigt finns det flera anledningar att försöka minimera antalet tester på levande djur; till exempel ekonomiska, praktiska och inte minst djuretiska skäl. READ MORE

  5. 5. Re-examining the dynamics of the Milky Way with new distance estimates

    University essay from Lunds universitet/Astronomi

    Author : John Wimarsson; [2018]
    Keywords : Milky Way dynamics; Gaia; distance estimates; Physics and Astronomy;

    Abstract : The use of reliable distance estimates is key to derive accurate three-dimensional velocities of celestial objects. Systematic overestimation and large uncertainties in the distances will thus provide misleading information of an object's kinematics. READ MORE
