Convergence methods on time scales

AIP Conference Proceedings, 2013
In this paper, we introduce the concepts of lacunary statistical convergence and strongly lacunary Cesaro summability of delta measurable functions on time scales and obtain some inclusion results between them. We also display some examples containing discrete and continuous cases.

Convergence time [fixed-mobile telephony convergence]

Communications Engineer, 2004
Fixed-mobile convergence, that is, using a mobile terminal for both fixed and mobile calls, seems an easy enough concept, but bringing it to reality is proving no easy task. The handset would act as normal when on the move, using cellular radio frequencies and protocols to communicate with the mobile networks' base stations. Indoors, the device becomes

��- convergence on time scale

2011
In the present paper we will give some new notions, such as -convergence and -Cauchy, by using the -density and investigate their relations. It is important to say that, the results presented in this work generalize some of the results mentioned in the theory of statistical convergence.

Convergence of Averaged Occupation Times

Canadian Mathematical Bulletin, 1975
Let X = {Xt, t ≥ 0} be a stationary Markov process with values in a measurable space (S, ℬ), transition function p, and initial distribution concentrated at a point x ∊ S. The occupation times of a set A ∊ ℬ are defined for t ≥ 0 bywhere 1A is the indicator function of A.

Finite- and fixed-time convergent algorithms: Design and convergence time estimation

Annual Reviews in Control, 2019
Abstract This paper presents a review of finite- and fixed-time convergent algorithms for dynamic systems of various dimensions and relative degrees, with or without disturbances. The review mainly focuses on finite- and fixed-time convergent algorithms, which provide explicit and easily computable upper estimates for the corresponding convergence ...

Convergence acceleration for simulated time‐reversal

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2009
Summary: Purpose - The purpose of this paper is to report on the use of conjugate-gradients (CG) as a means to accelerate the convergence of the iterative time-reversal algorithm used for optimisation of electromagnetic devices. Design/methodology/approach - The numerical time-domain transmission line modelling method is used for time-reversal ...
