In this paper the influence of shaper parameters on characteristics acceleration pulses (peak value and duration) reproduced mechatronic shock machines is analyzed. A comparison obtained experimentally by computational methods presented. Recommendations for clarifying requirements methodological calculations pulse are given. The dependence elastic force its deformation characteristic peak durat...

Cucumber seedling growth under constant and fluctuating photosynthetic photon flux density (PPFD) light (CPL FPL, respectively) was examined to discuss whether plants can acclimate CPL versus FPL. The FPL created in a chamber by artificially reproducing fluctuations ground-level sunlight PPFD using phosphor-converted white LEDs. daily mean at the canopy surface photoperiod were same for grown t...

This paper examines stability analysis of two classes of improved backward Euler methods, namely split-step $(theta, lambda)$-backward Euler (SSBE) and semi-implicit $(theta,lambda)$-Euler (SIE) methods, for nonlinear neutral stochastic delay differential equations (NSDDEs). It is proved that the SSBE method with $theta, lambdain(0,1]$ can recover the exponential mean-square stability with some...
