  1. 1. Demand Forecasting of Automobile Spare Parts after the End-of-Production - A review of demand forecasting models

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Abid Ali; Arosha Ratnayake; [2023-07-03]
    Nyckelord :Demand forecasting; Spare parts; Automobile; End-of-Production EOP ; PRISMA; AHP; MCDM;

    Sammanfattning : Demand forecasting of spare parts plays a crucial role in automobile industry where it generally requires a significant attention in controlling inventory. It is possible to maintain an optimal stock level when there is a continues supply at the Original Equipment Manufacturers (OEMs). LÄS MER

  3. 2. 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.

  4. 3. Pilot Study on Working Memory : Investigating Single Trial Decoding to Find the Best Stimulus and Target for a Future Personalized Neurofeedback

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Erik Gasparini; [2023]
    Nyckelord :Visual working memory; Personalised neurofeedback; Visual stimulus; Targeted brain region.;

    Sammanfattning : A standard Neurofeedback approach to mitigate the working memory decline in some fragile groups (elderly, subjects affected by stroke or Alzheimer's disease) can be suboptimal for some patients. The goal of this research is to investigate which visual stimulus (among colour, geometrical shape, direction, and symbol) is the most suited for each of the six healthy participants and which brain areas are the most discriminative, during the maintenance of a presented stimulus in a retro-cue-based working memory experiment.

  5. 4. Optimal kontroll av en cykel

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Ibrahim Abakar; [2022]
    Nyckelord :Optimal kontroll; cykel; dynamisk programmering; LQR-kontroll;

    Sammanfattning : Optimal kontroll är studien om hur man på bästa sätt kan kontrollera ett system, givet kontrollvariabler, för att minimera ett specifikt prestationsindex. Denna teori användes för att studera hur en cykel optimalt skulle kunna balanseras. LÄS MER

  7. 5. The Effect of Theta Binaural Beats on Executive Functions, Heart Rate Variability, Self-Rated Stress and Tiredness

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för psykologi

    Författare :Sara Moradi; Linda Orrell; [2022]
    Nyckelord :;

    Sammanfattning : Binaural beats (BB) are a phenomenon occurring when two sinus tones of slightly different frequencies are presented separately to each ear, resulting in the perception of a beating sound. BB is believed to cause brainwave (BW) entrainment, inducing different effects depending on their frequency. LÄS MER
