Description
In this article we have developed the optimum speed diagrams for small movements of electric drive’s actuating device. We have identified analytical dependences of position of automatic regulation of system control signal of time, which allows to form the optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision

MORPHOLOGICAL AND CYTO-BIOCHEMICAL BASIS OF SHOOT FORMATION OF CEREALS
DescriptionProcess of shoot formation of cereals is associated with the formation of zone shortened internodes, establishes buds certain capacity and completes transition by growth and formation of crop aboveground mass of each individual. Process of shoot formation is divided into three phases - preparatory, hidden and visible tillering, each of which is different peculiar morphological and cytobiochemical development

Description
A method for predicting the wear rate of the drive roller chains in programs with internal teeth was developed. We took into account the way the friction in the hinge when forced transverse oscillation branches chain loop, which is based on probabilistic and statistical representation of the wear process

Description
The purpose of work is increasing the efficiency of the inertial conveyor by applying the link of preacceleration of the linear induction electric drive (LIED). One of the tasks is creation a mathematical model and its research. LIED design with the link of preliminary dispersal was chosen during the work, its installation coordinated on the inertial conveyor. The mathematical model created and its researches conducted. The results of the researches confirm the increasing of the efficiency of the inertial conveyor
