    Ferroelectric Properties and Electrocaloric Effect in Dy2O3 Substitution on Lead-Free (Na0.5 Bi0.5)0.94 Ba0.06TiO3 Ceramic حسب Turki, O.

    منشور في 2023
    "…Higher stability of the ferroelectric (FE) phase was obtained at room temperature for the compositions y = 0.01, 0.02 and 0.05, with optimum values for y = 0.02 as remanent polarization Pr = 32µC/cm2, as well as piezoelectric coefficients d33 = 137 pC/N, kp = 0.27 and kt = 0.16, whereas a higher content of Dy (y = 0.08) induced a remarkable decrease of the ferroelectric and piezoelectric properties. …"

    Use of Electrical Resistivity Tomography to Study the Impact of Long-Term Application of Sewage Sludge: Case Study of Oued Souhil Experimental Station, Nabeul (Tunisia) حسب Hechmi, Sarra

    منشور في 2022
    "…Laboratory analyses were conducted on soil samples taken in the middle of the treated plots at four depths (0–20 cm), (20–40 cm), and (40–60 cm) for a comparison with the ERT survey result. ERT panels showed a general decrease in soil resistivity below (40 cm) with extremely low resistivity in each plot’s corner, indicating a vertical leaching and a lateral migration of conductive materials in all the treatments. …"

    Failure mode analysis for single-phase Multi-level qZSI interfacing PV system to utility grid حسب Rahman, Syed

    منشور في 2017
    "…In this paper, control algorithm for the operation of Multi-level qZSI with module failures (up to three modules out of total 16) is discussed. The power deficit due to a failure of the module is reflected as a decrease in the grid current reference. …"

    Sliding mode control based dtc of sensorless parallel-connected two five-phase pmsm drive system حسب Kamel T.

    منشور في 2018
    "…In order to increase the proposed drive robustness and decrease its complexity and cost, the rotor speeds, rotor positions, fluxes as well as torques are estimated by using a sliding mode observer (SMO) scheme. …"

    Tandem osmotic engine based on hydrogel particles with antipolyelectrolyte and polyelectrolyte effect fuelled by both salinity gradient modes حسب Padmanabhan, Anjali Cheeramthodi

    منشور في 2021
    "…The swelling of hydrogel with a polyelectrolyte effect and shrinking of hydrogel particles possessing an antipoly-electrolyte effect in desalinated water, and subsequent shrinking of hydrogel with polyelectrolyte and swelling of hydrogel antipolyelectrolyte effect in saline water, generate power in both increasing and decreasing salinity modes. …"
