INFLUENCE OF CONTROL CURRENT WAVEFORM ON ROTOR NUTATION OF THREE-DEGREES-OF-FREEDOM ELECTRIC MACHINE
Технічна електродинаміка, 2023 The design of the electric machine with three degrees of freedom of the rotor with an external magnetic core, containing permanent magnets, and an internal magnetic core is considered. The both magnetic cores are rotating.

Experimental model for the description of the behaviour of a 9-mm projectile at a target
Forensic Sciences Research, 2021 Analysis of crime scenes involving single-fire-gun projectiles requires the determination of the direction of arrival of a projectile at the target and other factors to reconstruct events.

Determination of Global Stability of the Slosh Motion in a Spacecraft via Num Erical Experiment [PDF]
Journal of Astronomy and Space Sciences, 2003 The global stability of the attitude motion of a spin-stabilized space vehicle is investigated by performing numerical experiment. In the previous study, a stationary solution and a particular resonant condition for a given model were found by using ...

Mathematic Modelling and Numerical Analysis for a Novel Inner-Type Nutation Magnetic Drive
Energies, 2020 This paper presents an inner-type of magnetic gears for non-contact driving, based on the nutation gearing principle. An improved three-dimensional analytical model, based on the magnetic vector potential of rectangular permanent magnets, via the ...

Red Light and Glucose Enhance Cytokinin-Mediated Bud Initial Formation in Physcomitrium patens
Plants, 2022 Growth and development of Physcomitrium patens is endogenously regulated by phytohormones such as auxin and cytokinin. Auxin induces the transition of chloronema to caulonema.

Long-period nutational-precessional motions of the instantaneous Earth rotation pole
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Nutation and the Oppolzer's Terms [PDF]
Symposium - International Astronomical Union, 1980 Two fundamental frames of reference are used in the study of the rotation of the Earth: the nonrotating celestial coordinate system XYZ attached to the directions to stars and/or extragalactic sources, and the terrestrial coordinate system xyz attached in “a prescribed way” to several points (observatories) on the surface of the Earth or to the pencil ...

Basic Earth's Parameters as estimated from VLBI observations
Geodesy and Geodynamics, 2017 The global Very Long Baseline Interferometry observation for measuring the Earth rotation's parameters was launched around 1970s. Since then the precision of the measurements is continuously improving by taking into account various instrumental and ...
