    Unsupervised Multitaper Spectral Method for Identifying REM Sleep in Intracranial EEG Recordings Lacking EOG/EMG Data by Kyle Q. Lepage, Sparsh Jain, Andrew Kvavilashvili, Mark Witcher, Sujith Vijayan

    Published 2023-08-01
    “…Existing methods of sleep scoring using only iEEG recordings accurately classify all stages of sleep, with the exception that wake (W) and rapid-eye movement (REM) sleep are not well distinguished. A novel multitaper (Wake vs. REM) alpha-rhythm classifier is developed by generalizing K-means clustering for use with multitaper spectral eigencoefficients. …”

    Effect of spectrum occupancy on the performance of a real valued neural network based energy detector by Onumanyi, Adeirza J., Onwuka, Elizabeth Nonyelu, Aibinu, Abiodun Musa, Ugweje, Okechukwu, Salami, Momoh Jimoh Eyiomika

    Published 2014
    “…We also observed that the RVNN based ED would provide better precision performance characteristics over the Periodogram, Welch and Multitaper based ED schemes compared herein. Hence, the RVNN based ED suffices as a favourable choice for CR application even under varying occupancy conditions.…”

    Effective elastic thickness of South America and its implications for intracontinental deformation by Perez-Gussinye, M, Lowry, A, Watts, A

    Published 2007
    “…We present here a new Te map of South America generated using a compilation of satellite-derived (GRACE and CHAMP missions) and terrestrial gravity data (including EGM96 and SAGP), and a multitaper Bouguer coherence technique. Our Te maps correlate remarkably well with other proxies for lithospheric structure: areas with high Te have, in general, high lithospheric mantle shear wave velocity and low heat flow and vice versa. …”
