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

A Hierarchy of Time-Scales and the Brain

open access: yesPLoS Computational Biology, 2008
In this paper, we suggest that cortical anatomy recapitulates the temporal hierarchy that is inherent in the dynamics of environmental states. Many aspects of brain function can be understood in terms of a hierarchy of temporal scales at which representations of the environment evolve. The lowest level of this hierarchy corresponds to fast fluctuations

Efficient monitoring of large scale infrastructure as a service clouds [PDF]

open access: yes, 2015
Cloud computing has had a transformative effect upon distributed systems research. It has been one of the precursors of supposed big data revolution and has amplified the scale of software, networks, data and deployments.

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.

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 ...

Real-Time Scale Selection in Hybrid Multi-Scale Representations [PDF]

open access: yes, 2003
Local scale information extracted from visual data in a bottom-up manner constitutes an important cue for a large number of visual tasks. This article presents a framework for how the computation of such scale descriptors can be performed in real time

Unilateral Laplace Transforms on Time Scales

open access: yesMathematics, 2022
We review the direct and inverse Laplace transforms on non-uniform time scales. We introduce full backward-compatible unilateral Laplace transforms and studied their properties. We also present the corresponding inverse integrals and some examples.

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.

Measure on Time Scales with Mathematica [PDF]

open access: yes, 2006
In this paper we study the Lebesgue Δ-measure on time scales. We refer to [3, 4] for the main notions and facts from the general measure and Lebesgue Δ integral theory. The objective of this paper is to show how the main concepts of Mathematica can be applied to fundamentals of Lebesgue Δ- and Lebesgue $\nabla$- measure on an arbitrary time scale and ...
