    Effects of water-table depth on seed quality as β-glucan content in waxy and non-waxy naked barley grains by Satoko Yasumoto, Yohei Kawasaki, Hidetoshi Mochizuki, Yuta Shimizu, Satoshi Kawakita

    Published 2025-01-01
    “…During ripening, the β-glucan content in both waxy and non-waxy cultivars increased sharply from the 20th to the 30th days after anthesis. In waxy-type cultivar ‘Fukumifiber’, β-glucan further accumulated from the 30th to the 50th days after anthesis, but the accumulation was suppressed as the water-table depth shallowed. …”

    Quadrature-Phase-Locked-Loop-Based Back-Electromotive Force Observer for Sensorless Brushless DC Motor Drive Control in Solar-Powered Electric Vehicles by Biswajit Saha, Aryadip Sen, Bhim Singh, Kumar Mahtani, José A. Sánchez-Fernández

    Published 2025-01-01
    “…A back-electromotive force (EMF) observer integrated with an enhanced quadrature-phase-locked-loop (QPLL) structure is proposed for accurate rotor position estimation, addressing limitations of existing control methods at low speeds and under dynamic conditions. The study replaces the conventional arc-tangent technique with a QPLL-based approach, eliminating low-pass filters to enhance system adaptability and reduce delays. …”
