Dynamics of Nanoparticle Self-Assembly by Liquid Crystal Sorting in Two Dimensions
Frontiers in Physics, 2021 We study nonlinear dynamical equations for coupled conserved and non-conserved fields describing nanoparticle concentration and liquid crystal order parameter, respectively, and solve them numerically over bidimensional domains. These equations model the

Existence of positive solutions for second-order nonlinear neutral dynamic equations on time scales
Moroccan Journal of Pure and Applied Analysis, 2021 In this article we study the existence of positive solutions for second-order nonlinear neutral dynamic equations on time scales. The main tool employed here is Schauder’s fixed point theorem.

Modelling of a dynamic multiphase flash: the positive flash. Application to the calculation of ternary diagrams [PDF]
, 2004 A general and polyvalent model for the dynamic simulation of a vapor, liquid, liquid-liquid, vapor-liquid or vapor-liquid-liquid stage is proposed. This model is based on the -method introduced as a minimization problem by Han & Rangaiah (1998) for ...

Dynamic Structural Equation Models
Structural 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
Electronic 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}

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

A connection between weighted Hardy’s inequality and half-linear dynamic equations
Advances in Differential Equations, 2019 In this paper, we give an affirmative answer to the following question: Is the solvability of some nonlinear dynamic equations on a time scale T$\mathbb{T}$ not only sufficient but in a certain sense also necessary for the validity of some dynamic Hardy ...
