The Impact of Multiple Autoclave Cycles on the Surface Roughness of Thermally Treated Nickel-Titanium Endodontic Files by Ba-Hattab, Raidan

“…An unsterilized group was assigned as the pre-autoclaving group (Cycle 0), and the other three groups underwent various autoclave sterilization cycles (Cycles 1, 5, and 10). The roughness average (Ra), root mean square (Rq), and average maximum peak-to-valley height (Rz) values were evaluated using SEM and ImageJ software. …”

Driver Drowsiness Detection Study using Heart Rate Variability analysis in Virtual Reality Environment by Chowdhury, Muhammad E.H.

“…Figure 4 shows the PSD averaged over trials for sample participants in case of active and drowsy states. As it can be seen from Fig. 4, there is a significant difference in the LF/HF ratios, as it decreased drastically from 4.164 (Fig. 4A) when subject was awake to 1.355 (Fig. 4B) when subject was drowsy. …”

The impact of PV generation and load types on the impedance relays during both balanced and unbalanced faults by Kamel, Rashad M.

“…When single line to ground fault occurs at the PV bus (far from relay location), the dynamic loads increase the relay impedance, while the PV plant decreases the relay impedance. When a single phase to ground fault occurs at the relay bus (load bus), the dynamic load decreases the relay impedance, and the PV plant increases it. …”

Thermodynamic analysis of solar-driven chemical looping steam methane reforming over Cr2O3/Cr redox pair by Bhosale, Rahul

“…The total solar energy required to drive the CS process (Q-solar-CS) rises by 1498.8 kW as the CH4/Cr2O3 molar ratio upsurges from 0.5 to 3. In case of the CSH process, when the TL increases from 500 to 1400 K, the Q solar CSH decreases by 54.5 kW and further surge in the TL from 1400 to 2050 K yields into upturn in the Q-solar-CSH by 108.5 kW. …”
