Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Efficient thermal management in advanced industrial systems requires improved heat transfer performance, particularly under non‐Newtonian fluid behavior and complex surface geometries. This study investigates the two‐dimensional flow and heat transfer characteristics of ternary hybrid nanofluids over both stationary and moving wedge surfaces ...

Chebyshev centers, ?-Chebyshev centers and the Hausdorff metric
Manuscripta Mathematica, 1989 In this paper, we affirmatively answer an open question raised by P.Szeptycki and Vlech in (9) and give a new characterization of p-uniformly convex Banach space. The Lipschitz stability of the set of e-Chebyshev centers Ge(A) under the perturbations of A and G is also proved.

Best approximation in Chebyshev subspaces of L(l_{1}^{n},l_{1}^{n}) [PDF]
Opuscula Mathematica, 2009 Chebyshev subspaces of \(\mathcal{L}(l_1^n,l_1^n)\) are studied. A construction of a \(k\)-dimensional Chebyshev (not interpolating) subspace is given.

Image Encryption Algorithm Using Multi-Level Permutation and Improved Logistic–Chebyshev Coupled Map
Information, 2023 To improve the randomness of the Chebyshev chaotic sequences by coupling the Logistic map and the Chebyshev map, a new one-dimensional Logistic–Chebyshev chaotic map (LCCM) is first presented in this paper.

Carbon Energy, EarlyView.ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

Representation by Chebyshev Polynomials for Sums of Finite Products of Chebyshev Polynomials [PDF]
Symmetry, 2018 In this paper, we consider sums of finite products of Chebyshev polynomials of the first, third, and fourth kinds, which are different from the previously-studied ones. We represent each of them as linear combinations of Chebyshev polynomials of all kinds whose coefficients involve some terminating hypergeometric functions 2 F 1 .

Non-archimedean Chebyshev centers [PDF]
, 1987 In a recent paper, M.Z.M.C. Soares [3] introduced the concepts of Chebyshev radii and centers in a non-archimedean normed space E and posed some of the main problems in the non-archimedean theory of best simultaneous approximation. In this paper we prove,

A Low-Complexity Massive MIMO Precoding Algorithm Based on Chebyshev Iteration
IEEE Access, 2017 Precoding algorithm is used to transmit signals effectively and to reduce the interferences from other user terminals in the massive multiple-input-multiple-output (MIMO) systems. In order to decrease the computational complexity of the precoding matrix,

Nonlinear permuted Granger causality
Canadian Journal of Statistics, EarlyView.Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

Consensus Acceleration in Multiagent Systems with the Chebyshev Semi-Iterative Method [PDF]
, 2011 We consider the fundamental problem of reaching consensus in multiagent systems; an operation required in many applications such as, among others, vehicle formation and coordination, shape formation in modular robotics, distributed target tracking, and ...
