Best multiplier Approximation in L_(p,∅_n ) (B)
Al-Mustansiriyah Journal of Science, 2019 The purpose of this paper is to find best multiplier approximation of unbounded functions in L_(p,∅_n ) –space by using Trigonometric polynomials and by de la Vallee- Poussin operators.

On approximation processes defined by a cosine operator function; pp 214–224 [PDF]
Proceedings of the Estonian Academy of Sciences, 2017 In this paper we introduce the Blackman- and Rogosinski-type approximation processes in an abstract Banach space setting. The historical roots of these processes go back to W. W. Rogosinski in 1926.

Padé approximant related to remarkable inequalities involving trigonometric functions
Journal of Inequalities and Applications, 2016 In this paper we, respectively, give simple proofs of some remarkable trigonometric inequalities, based on the Padé approximation method. We also obtain rational refinements of these inequalities.

Trigonometric approximation in the norms and seminorm [PDF]
Studia Mathematica, 1984 There are proved four theorems on approximation by trigonometric polynomials of some periodic functions and their Weyl derivatives. Estimates obtained here can be treated as generalizations of the results of \textit{T. Ganelius} [Math. Scand. 4, 247-258 (1957; Zbl 0077.070)] and \textit{V. A. Popov} [C. R. Acad. Bulg. Sci. 32, 1319-1322 (1979; Zbl 0439.

On approximation by trigonometric Lagrange interpolating polynomials II [PDF]
Bulletin of the Australian Mathematical Society, 1989 We show that trigonometric Lagrange interpolating approximation with arbitrary real distinct nodes in Lp space for 1 ≤ p < ∞, as that with equally spaced nodes in Lp space for 1 < p < ∞ in an earlier paper by T.F. Xie and S.P. Zhou, may also be arbitrarily “bad”.

C1 rational quadratic trigonometric spline
Egyptian Informatics Journal, 2013 A Bézier like C1 rational quadratic trigonometric polynomial spline is developed. It defines two shape parameters in each subinterval. The approximation and geometric properties are investigated. The curvature continuity is established.

Approximations to inverse tangent function
Journal of Inequalities and Applications, 2018 In this paper, we present a sharp Shafer-type inequality for the inverse tangent function. Based on the Padé approximation method, we give approximations to the inverse tangent function. Based on the obtained result, we establish new bounds for arctanx.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading
Advanced Engineering Materials, EarlyView.This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
