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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Máté Károly Tóth; [2023]
    Nyckelord :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;

    Sammanfattning : 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. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

  4. 3. Embedded digital filter design and implementation

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiao Su; [2023]
    Nyckelord :;

    Sammanfattning : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.

  5. 4. Microwave substrate filter implementationfor an advanced 5G antenna system

    Magister-uppsats, Högskolan i Halmstad

    Författare :Arhayem M Bashar; [2021]
    Nyckelord :;

    Sammanfattning : This master thesis has been done at Ericsson AB (2018) in collaboration with LeonardoPadial Torán. Microwave filters for the future 5G have become an increasingly interesting researchtopic. The conventional design theory of microwave filters is no longer valid. LÄS MER

  7. 5. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Kristinn Arnar Ormsson; [2021]
    Nyckelord :Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

    Sammanfattning : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.
