  1. 11. 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. 12. Recording Bass-Cabinet: Microphone Choice and Microphone Placement

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Diana Carmona Velazquez; [2023]
    Keywords : audio technology; recording bass; recording; bass; microphone choice; bass-cabinet; microphone placement; rock; ljudteknik; mikrofon val; bas; rock;

    Abstract : Research on microphone choice and placement has been previously made for a variety of instruments, such as drums, vocals, and guitar, to name a few. However, in comparison, very little research has been made on the bass-cabinet. READ MORE

  4. 13. Automated Measurement of Relative HF Antenna Properties using WSPR

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

    Author : Axel Blomqvist; [2023]
    Keywords : ;

    Abstract : The performance of antennas is an important factor in creating a well performing radio communication channel. Traditionally measuring High Frequency (HF) antennas is an expensive and complicated process. J. Zander[1] proposes an alternative method of evaluating antenna performances in the HF band. READ MORE

  5. 14. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

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

    Author : Eduardo Salvador Lopez; [2023]
    Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  6. 15. Fano Resonances in Time-Dependent Wells

    University essay from Uppsala universitet/Materialteori

    Author : Anton Gregefalk; [2023]
    Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

    Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE
