Hermite-Hadamard Type Inequalities for the Class of Convex Functions on Time Scale

open access: yesMathematics, 2019
We investigate a time scale version of two auxiliary functions for the class of convex functions. We derive several novel dynamic inequalities for these classes of convex functions.

Time‐scale transformations of discrete time processes [PDF]

open access: yesJournal of Time Series Analysis, 2003
Abstract.  This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well‐known results on fixed‐interval aggregation, such as when monthly data are aggregated into quarters.

Irreversibility time scale [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2006
Entropy creation rate is introduced for a system interacting with thermostats (i.e., for a system subject to internal conservative forces interacting with “external” thermostats via conservative forces) and a fluctuation theorem for it is proved. As an application, a time scale is introduced, to be interpreted as the time over which irreversibility ...

Crustal evolution events in the Chinese continent: evidence from a zircon U-Pb database

open access: yesInternational Journal of Digital Earth, 2020
The zircon U-Pb chronology database provides a good opportunity to obtain important zircon growth peak periods in the Earth's history so as to study the origin and evolution of the crust.

Further new refinements in h-stability conditions for nonlinear abstract dynamic equations on time scales and applications [PDF]

open access: yesSurveys in Mathematics and its Applications, 2021
In this paper, we study the h-stability problems of some classes of dynamic equations as an extension of exponential stability. We derive some sufficient conditions that guarantee h-stability of perturbed dynamic equations using Grönwall-Bihari and ...

Almost Periodic Time Scales and Almost Periodic Functions on Time Scales [PDF]

open access: yesJournal of Applied Mathematics, 2015
We propose some new concepts of almost periodic time scales and almost periodic functions on time scales and give some basic properties of these new types of almost periodic time scales and almost periodic functions on time scales. We also give some comments on a recent paper by Wang and Agarwal (2014) concerning a new almost periodic time scale.

Linearization by input–output injections on homogeneous time scales; pp. 387–397 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
The problem of linearization by input–output (i/o) injections is addressed for nonlinear single-input single-output systems, defined on a homogeneous time scale.

Observable space of the nonlinear control system on a homogeneous time scale; pp. 11–25 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2014
The observability property of the nonlinear system, defined on a homogeneous time scale, is studied. The observability condition is provided through the notion of the observable space.
