Stieltjes functions and spectral analysis in the physics of sea ice [PDF]

open access: yesNonlinear Processes in Geophysics, 2023
Polar sea ice is a critical component of Earth’s climate system. As a material, it is a multiscale composite of pure ice with temperature-dependent millimeter-scale brine inclusions, and centimeter-scale polycrystalline microstructure which is largely ...

Teleseismic earthquake wavefields observed on the Ross Ice Shelf

open access: yesJournal of Glaciology, 2021
Observations of teleseismic earthquakes using broadband seismometers on the Ross Ice Shelf (RIS) must contend with environmental and structural processes that do not exist for land-sited seismometers.

The implementation of an improved differential transform scheme on the Schrodinger equation governing wave-particle duality in quantum physics and optics

open access: yesResults in Physics, 2022
Seeking solutions to nonlinear differential equations cannot be overemphasized as this illuminates clarity in the dynamical behavior of the described model, and thus, enables precise forecasting of the processes with respect to time.In this study, Elzaki

Interaction effects from the elastodynamic scattering by two symmetric spherical cavities

open access: yesAIP Advances, 2023
The scattering of harmonic waves has been studied extensively for problems in quantum mechanics, acoustics, electromagnetics, and elasticity. Solutions to elastodynamic problems are the basis for ultrasonic non-destructive evaluation measurement models ...

Analysis of results of interpretation of elastic parameters of solid core of the Earth from the standpoint of current geomechanics

open access: yesГеофизический журнал, 2017
It follows from the basic principles of mechanics of deformable solids relating to the strength, stability and propagation of elastic waves that the inner core of the Earth cannot exist in the form of a spherical structure in the assumed thermobaric ...

Liquid Droplet Microresonators

open access: yesSensors, 2019
We provide here an overview of passive optical micro-cavities made of droplets in the liquid phase. We focus on resonators that are naturally created and suspended under gravity thanks to interfacial forces, illustrating simple ways to excite whispering ...

NONLINEAR STABILITY OF SINUSOIDAL VELAROIDAL SHELL

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2018
The nonlinear analysis of thin-walled shells is not a rarity, particularly the nonlinear strength one. Many works are devoted to linear and nonlinear analyses of shells of classical form: cylindrical, spherical, hemispherical, shallow, conical.

Microaccelerometer on Surface Acoustic Waves with a Ring Resonator on Anisotropic Material

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2019
Introduction. Diagnostic systems are designed to monitor the condition of operational components (for example, on the railway). It is imperative that micro-electromechanical systems (MEMS) equipped with acceleration sensors (accelerometers) be used as ...
