Certain novel estimates within fractional calculus theory on time scales

open access: yesAIMS Mathematics, 2020
The key purpose of this study is to suggest a delta Riemann-Liouville (RL) fractional integral operators for deriving certain novel refinements of Pólya-Szegö and Čebyšev type inequalities on time scales.

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.

The asymptotic properties of the dynamic equation with a delayed argument [PDF]

open access: yesOpuscula Mathematica, 2006
In this paper, we present some asymptotic results related to the scalar dynamic equation with a delayed argument. Using the time scale calculus we generalize some results known in the differential and difference case to the more general dynamic case.

Nabla inequalities and permanence for a logistic integrodifferential equation on time scales

open access: yesOpen Mathematics, 2017
In this paper, by using the theory of calculus on time scales and some mathematical methods, several nabla dynamic inequalities on time scales are established. As an application, we apply the obtained results to a logistic integrodifferential equation on

On the Variation of Turbulence in a High-Velocity Tidal Channel

open access: yesEnergies, 2019
This study presents the variation in turbulence parameters derived from site measurements at a tidal energy test site. Measurements were made towards the southern end of the European Marine Energy Centre’s tidal energy test site at the Fall of Warness ...

Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]

open access: yes, 2000
Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).

A class of retarded Volterra-Fredholm type integral inequalities on time scales and their applications

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we study some new retarded Volterra-Fredholm type integral inequalities on time scales, which provide explicit bounds on unknown functions.
