Recurrence techniques for the calculation of bessel functions [PDF]

open access: yesPreprints of papers presented at the 14th national meeting of the Association for Computing Machinery on - ACM '59, 1959
where Fv(x) may be either J,(x) or Y,(x). If one is given Y,(x) and Yv+?(x) then Eq. (1) may be used to generate the functions Yv+,(x). For ? >> (x/2) the function Y,(x) increases extremely rapidly with increasing order, i.e., Y,(x) -(2,u/x) and the functions Y,+n(x) calculated from Eq. (1) yield good accuracy for large n. However, if one is given JA(x)

Generalized Almost Periodicity in Lebesgue Spaces with Variable Exponents, Part II

open access: yesMathematics, 2020
In this paper, we introduce and analyze several different notions of almost periodic type functions and uniformly recurrent type functions in Lebesgue spaces with variable exponent L p ( x ) .

Impaired Lung Functions Using Tidal Breath Analysis in High-risk Infants with Recurrent Wheezing

open access: yesTrends in Pediatrics, 2020
Objective: We aimed to investigate lung functions using tidal breath analysis (TBA) in high-risk infants with recurrent wheezing. Methods: Lung functions measured using TBA in infants with physician-diagnosed recurrent wheezing (≥3 episodes) who ...

Dynamical properties of direct products of discrete dynamical systems

open access: yesЖурнал Средневолжского математического общества, 2022
A natural way for creating new dynamical systems is to consider direct products of already known systems. The paper studies some dynamical properties of direct products of homeomorphisms and diffeomorphisms.

Management of a post-stroke patient

open access: yesНеврология, нейропсихиатрия, психосоматика, 2013
The management of a post-stroke patient represents is a challenge to modern neurology. Complete recovery of all functions requires only recurrent stroke prevention. If the patient continues to have motor, speech, and/or other disorders that are promising

On the convergence of Steffensen-type methods using recurrent functions nonexpansive mappings

open access: yesJournal of Numerical Analysis and Approximation Theory, 2009
We introduce the new idea of recurrent functions to provide a new semilocal convergence analysis for Steffensen-type methods (STM) in a Banach space setting.
