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. Phainesthai : Auditory Processes as Tools for Musical Composition

   University essay from Kungl. Musikhögskolan/Institutionen för komposition, dirigering och musikteori

   Author : Luka Aron; [2023]
   Keywords : music; psychoacoustics; auditory distortion products; tuning; just intonation; phenomenology;

   Abstract : The human auditory system can become an active agent in the production of sound when stimulated with specific tone combinations. The resulting auditory distortion products can be amplified and drawn attention to by employing certain just intonation practices – a compositional technique that may serve as a powerful catalyst for reaching different states of mind in listeners.
