1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

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

   Author : Máté Károly Tóth; [2023]
   Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

3. 2. Characterization of NOx sensor performance under oscillating pressure conditions

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Álvaro López Méndez; [2023]
   Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

   Abstract : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. READ MORE

4. 3. Parallel Operation of Grid-Forming Power Inverters

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

   Author : Alessia Camboni; [2023]
   Keywords : ;

   Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE

5. 4. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Guillaume Larrat; [2023]
   Keywords : Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

   Abstract : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. READ MORE

6. 5. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications
