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

Linearization by input–output injections on homogeneous time scales; pp. 387–397 [PDF]
Proceedings of the Estonian Academy of Sciences, 2014 The problem of linearization by inputâoutput (i/o) injections is addressed for nonlinear single-input single-output systems, defined on a homogeneous time scale.

Journal 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]
Journal 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).

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

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

Time‐scale transformations of discrete time processes [PDF]
Journal 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.

The asymptotic properties of the dynamic equation with a delayed argument [PDF]
Opuscula 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
Energies, 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 ...
