The mathematical relationship between the rock block shape and speed is sunken curve. The slope gradient and speed is convex curve. They are the same as the analysis of the empirical formula. Through rock-fall field test and based on the measurement,a simplified modified velocity formula is v ...
Current studies on the movement of saltation sand grains in aeolian flow over a complex surface are not satisfactory. This is mainly because the landform conditions of most aeolian sand transport models are based on flat sand beds without considering the effect of complex surface and slope on the...
The undercutting method applied together with the cut-and-fill technique has been realized through open-pit coal mining. To predict the time of slope failure, a method of forecasting slope failure time by the inverse velocity of slope surface proposed by Fukuzono (1985 in A new method for ...
The load was applied through a lost-motion rod; this allowed for the system to accelerate to the desired test velocity, prior to pulling the sample. The load was measured using a piezoelectric load cell (PCB model 222B). This was placed between the sample and the machine base. Download: ...

► Cyclosis provides functional polarity to cell areas around a light spot in Chara. ► A mediator of interplastid interactions moves at a velocity of streaming cytoplasm. ► Local cell fluorescence changes may arise after and aside from incident light pulse. ► Cytoplasm inflow from shaded...
The wave velocity of the specimen was measured, and those with large differences were excluded to reduce the dispersion. The test specimens are shown in Fig. 1. The RMT-150C rock mechanics test system and the Prisma E scanning electron microscope are shown in Fig. 2. Figure 1 Complete ...
RR-MA (p = 0.048), RR-MT (p = 0.025), FAI (MA, MV, MT) and RI (MA, MV, MT) all showed a constant decrease over time (all p < 0.001). Figure 1 (A–H). Longitudinal changes in ocular pulse waveform (PWF) parameters. The line graph represents the PWF ...
we will briefly introduce the training problem for SLFN. Given a training set S = {(xi, ti)| xi = (xi1, xi2, …, xin)T ∈ Rn,ti = (ti1, ti2, …, tim)T ∈ Rm}, wherexidenotes the input value andtirepresents the target, the outputoo...
