New Criteria of Oscillation for Linear Sturm–Liouville Delay Noncanonical Dynamic Equations

open access: yesMathematics, 2023
In this work, we deduce a new criterion that guarantees the oscillation of solutions to linear Sturm–Liouville delay noncanonical dynamic equations; these results emulate the criteria of the Hille and Ohriska types for canonical dynamic equations, and ...

Droplet Fate in a Cough Puff

open access: yesAtmosphere, 2020
The dynamic and thermodynamic evolution of droplets, in a size range characterizing a cough, has been analysed using basic equations of motion and coupled to the evolution of a spherical cloud puff in which they are supposed to be expired.

Improved Hille Oscillation Criteria for Nonlinear Functional Dynamic Equations of Third-Order

open access: yesMathematics, 2022
This paper aims to improve Hille oscillation criteria for the third-order functional dynamic equation p2(ξ)ϕγ2p1ξϕγ1yΔ(ξ)ΔΔ+a(ξ)ϕγy(g(ξ))=0, on an above-unbounded time scale T. The obtained results improve related contributions reported in the literature

Solution of the general dynamic equation along approximate fluid trajectories generated by the method of moments [PDF]

open access: yes, 2005
We consider condensing flow with droplets that nucleate and grow, but do not slip with respect to the surrounding gas phase. To compute the local droplet size distribution, one could solve the general dynamic equation and the fluid dynamics equations ...

Oscillation criteria for third-order functional half-linear dynamic equations

open access: yesAdvances in Difference Equations, 2017
In this paper, we study the third-order functional dynamic equation { r 2 ( t ) ϕ α 2 ( [ r 1 ( t ) ϕ α 1 ( x Δ ( t ) ) ] Δ ) } Δ + q ( t ) ϕ α ( x ( g ( t ) ) ) = 0 , $$ \bigl\{ r_{2}(t)\phi_{\alpha_{2}} \bigl( \bigl[ r_{1}(t) \phi _{\alpha _{1}} \bigl(

Relativistic Kinetics of Phonon Gas in Superfluids [PDF]

open access: yes, 2006
The relativistic kinetic theory of the phonon gas in superfluids is developed. The technique of the derivation of macroscopic balance equations from microscopic equations of motion for individual particles is applied to an ensemble of quasi-particles ...

Dynamic Structural Equation Models

open access: yesStructural Equation Modeling: A Multidisciplinary Journal, 2017
This article presents dynamic structural equation modeling (DSEM), which can be used to study the evolution of observed and latent variables as well as the structural equation models over time. DSEM is suitable for analyzing intensive longitudinal data where observations from multiple individuals are collected at many points in time.

Forced oscillation of second-order superlinear dynamic equations on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, by constructing a class of Philos type functions on time scales, we investigate the oscillation of the following second-order forced nonlinear dynamic equation $$x^{\Delta\Delta}(t)-p(t)|x(q(t))|^{\lambda-1}x(q(t))=e(t),\quad t\in\mathbb{T}
