The article provides an analytical review of the achieved crop yields under irrigation in experimental and production conditions. For today, best experience use irrigated land indicates that, subject to all agrotechnical requirements, yield early grain crops reaches 8-10 t / ha, corn - 10-14 oilseeds 4-6 vegetable over 60 which is about 90% their productivity experiments scientific institutions...

A nonlinear control system depending on a parameter is considered in finite-dimensional Euclidean space and finite time interval. The dependence the of reachable sets integral funnels corresponding differential inclusion studied. Under certain conditions system, degree this estimated. Problems targeting to target set presence an obstacle strict soft settings are considered. An algorithm for num...

Ukraine has favourable natural conditions for the cultivation of medicinal and aromatic plants, but there is a lack scientific knowledge practical guidelines their cultivation. Clary sage valuable prospective crop South deserves special attention. This study aimed to investigate theoretical mechanisms clary productivity formation on irrigated lands Southern Ukraine. The experimental basis data ...

This study investigates the influence of stimulus properties on explorative movement parameters in active touch. Using a PHANToM force-feedback device we generated virtual stimuli with different stiffness values. Participants freely explored pair-wise presented stimuli and were asked to select the softer one. Afterwards we analyzed their explorative movements considering the parameters velocity...
