The objective of this work was to evaluate the normalized difference water index (NDWI) based on Sentinel-2 imagery as a tool for monitoring pasture seasonal dynamics and inter-annual variability in a Mediterranean agro-silvo-pastoral system. Forty-one valid NDWI records were used between January ...
The instantaneous opening speed of the relief valve spool reaches 15.7 m/s, and the hinge point between the top beam and the column is most sensitive to the hysteresis effect (impact coefficient increases by 0.63). Keywords: hydraulic support; rotary impact; dynamic response; mechanical-hydraulic...
I want to acquire a set of pressures and temperatures to monitor the environment at my facility. The rates will not be in excess of one sample a second, and I expect little variation between each sample. With those values, I will do some logging, and alarming if the values go out of ...
Electrical characteristic experiments show that the discharge duration, the evolution of the gliding arc and the fracture frequency are affected by the pressure difference between the inlet and outlet of the igniter (∆p). With the increase in ∆p, the frequency of the trapezoidal envelope in ...
