In order to improve Multi-polar magnetic structure’s efficiency. Ansoft Maxwell of electromagnetic field finite element software is utilized to study the effect of different polarity arrangement of magnetic seeding element on the magnetic induction intensity of seeding element end and magnetic field distribution in the seeding air gap. As a result of the different electromagnetic coil current d...

The article discusses the questions of optimization parameters and operating modes tractor as a part arable unit by various criteria optimization. following have been chosen for consideration. These are minimum total energy costs, taking into account lost crop; emission carbon dioxide atmosphere; fuel consumption per 1 ha crops; maximum performance; traction efficiency tractor. optimal weight t...

Abstract. The seeder–feeder mechanism has been observed to enhance orographic precipitation in previous studies. However, the microphysical processes active seeder and feeder region are still being understood. In this paper, we investigate of a mixed-phase cloud passing over Swiss Alps, focusing on (1) fallstreaks enhanced radar reflectivity originating from top generating cells (seeder region)...

A 2-μm wavelength laser delivering up to 39-mJ energy, ∼10  ps duration pulses at 100-Hz repetition rate is reported. The system relies on chirped pulse amplification (CPA): a modelocked Er:Tm:Ho fiber-seeder is followed by a Ho:YLF-based regenerative amplifier and a cryogenically cooled Ho:YLF single pass amplifier. Stretching and compressing are performed with large aperture chirped volume Br...

A universal seeder has been created for sowing wheat seeds between rows of cotton. One the important tasks research is to compare traction resistance determined by theoretical and experimental ways. This article devoted comparison theoretically experimentally resistances a
