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.

Divergent Time Scale in Axelrod Model Dynamics [PDF]

open access: yes, 2006
We study the evolution of the Axelrod model for cultural diversity. We consider a simple version of the model in which each individual is characterized by two features, each of which can assume q possibilities.

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 ...

Time-Scales [PDF]

open access: yesJournal of Navigation, 1973
W. Palmer's note on Standard Time (this Journal, Vol. 25, page 535) may mislead some readers. He tends to confuse ‘Time’, as an abstract philosophical concept, with the measures of time, or time-scales, used in practice by astronomers, navigators, surveyors, physicists, electronic engineers and the general public.

Occupational Cohort Time Scales [PDF]

open access: yesJournal of Occupational & Environmental Medicine, 2015
This study explores how highly correlated time variables (occupational cohort time scales) contribute to confounding and ambiguity of interpretation.Occupational cohort time scales were identified and organized through simple equations of three time scales (relational triads) and the connections between these triads (time scale web).

Build Time Estimations for Large Scale Modelling [PDF]

open access: yes, 1998
Achieving speedy results in model making is very much desired if not a necessity in ahnost any manufacturing industry. There is no doubt that rapid prototyping contributes to this process.

On Hardy-Hilbert-type inequalities with α-fractional derivatives

open access: yesAIMS Mathematics, 2023
In the current manuscript, new alpha delta dynamic Hardy-Hilbert inequalities on time scales are discussed. These inequalities combine and expand a number of continuous inequalities and their corresponding discrete analogues in the literature.

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.
