Convergence Rates of Approximation by Translates [PDF]
, 1992 We consider the problem of approximating a function belonging to some function space by a linear combination of $n$ translates of a given function. Using a lemma by Jones (1990) and Barron (1991) we show that it is possible to define function spaces for which the rate of convergence to zero of the error is $O({1 \over \sqrt n})$ in any number of ...

Rate of Convergence Estimates for Nonselfadjoint Eigenvalue Approximations [PDF]
Mathematics of Computation, 1973 In this paper, a general approximation theory for the eigenvalues and corresponding subspaces of generalized eigenfunctions of a certain class of compact operators is developed. This theory is then used to obtain rate of convergence estimates for the errors which arise when the eigenvalues of nonselfadjoint elliptic partial differential operators are ...

Journal of Physics D: Applied Physics, 2020 Phase-change memory materials are promising candidates for beyond-silicon, next-generation non-volatile-memory and neuromorphic-computing devices; the canonical such material is the chalcogenide semiconductor alloy Ge2Sb2Te5.

Rigorous numerical approximation of escape rates [PDF]
Nonlinearity, 2006 An interval map with holes is a mathematical model which is used in the study of nonequilibrium statistical mechanics. We use Ulam's method to approximate the escape rate for an interval map with holes and find a bound on the approximation error. © 2006 IOP Publishing Ltd and London Mathematical Society.

A New Kantorovich-Type Rational Operator and Inequalities for Its Approximation
Mathematics, 2022 We introduce a new Kantorovich-type rational operator. We investigate inequalities estimating its rates of convergence in view of the modulus of continuity and the Lipschitz-type functions.

α-Schurer Durrmeyer operators and their approximation properties
Annals of the University of Craiova. Mathematics and computer science series, 2023 The key goal of the present research article is to introduce a new sequence of linear positive operator i.e., α-Schurer Durrmeyer operator and their approximation behaviour on the basis of function η (z), where η infinitely differentiable on [0,1], η(z ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

Approximation properties of a new family of Gamma operators and their applications
Advances in Difference Equations, 2021 The present paper introduces a new modification of Gamma operators that protects polynomials in the sense of the Bohman–Korovkin theorem. In order to examine their approximation behaviours, the approximation properties of the newly introduced operators ...

Functional Relationships between Kinetic, Flow, and Geometrical Parameters in a High-Temperature Chemical Microreactor. [PDF]
, 2018 Computational fluid dynamics (CFD) simulations and isothermal approximation were applied for the interpretation of experimental measurements of the C10H7Br pyrolysis efficiency in the high-temperature microreactor and of the pressure drop in the flow ...
