Studies generalization of shape change of equipotential surfaces of stress-deformed objects

open access: yesТехнічна інженерія, 2023
The vast majority of analytical studies of the stress-strain state of various objects of technical systems, performed at the stage of their development and design, show that the operational characteristics of these technical objects are determined by the

Cassini Ovals in Dynamic Geometry of Polynomials [PDF]

open access: yesUniversal Journal of Applied Mathematics, 2015
In this paper, we investigate the behavior of critical points of some polynomials whose roots are the vertices of some parallelogram, in case of rotation two of them on a given circle. In this case, the trajectory is the Cassini ovals.

Transient Flashes in Saturn’s UV Aurora: An Analysis of Hubble Space Telescope 2013–2017 Campaigns and Cassini Magnetic Field Measurements

open access: yesUniverse, 2022
We examined Hubble Space Telescope images of Saturn’s northern UV aurora in 2013–2017, identified 29 short-lived flashes, and examined simultaneous magnetometer data collected by the Cassini orbiter.

ANALYSIS OF SPATIAL-TIME CHARACTERISTICS OF A RADIO LINE WITH MULTIPATH WITHIN 5G TECHNOLOGY

open access: yesInformation and Telecommunication Sciences, 2020
Background. As a result of the reflection of rays from buildings, from the surface of the Earth or from horizontal boundaries between different layers of the atmosphere, multipath effects occur that cause fast fading, which affects the quality of service.

IMF dependence of Saturn's auroras: modelling study of HST and Cassini data from 12–15 February 2008 [PDF]

open access: yesAnnales Geophysicae, 2010
To gain better understanding of auroral processes in Saturn's magnetosphere, we compare ultraviolet (UV) auroral images obtained by the Hubble Space Telescope (HST) with the position of the open-closed field line boundary in the ionosphere calculated ...

Dieless bulging and nonlinear buckling of longan-shaped pressure hull

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2023
In this study, the dieless bulging and nonlinear buckling behaviours of a stainless longan-shaped pressure hull were investigated. According to the Cassini oval equation, the longan shape has a shape index of 0.1.

Magnetospheric mapping of the dayside UV auroral oval at Saturn using simultaneous HST images, Cassini IMF data, and a global magnetic field model [PDF]

open access: yesAnnales Geophysicae, 2011
We determine the field-aligned mapping of Saturn's auroras into the magnetosphere by combining UV images of the southern dayside oval obtained by the Hubble Space Telescope (HST) with a global model of the magnetospheric magnetic field.
