The nanofluid flows in the channel with linearly varying wall temperature
Case Studies in Thermal Engineering, 2021 In many applications of heat exchanger, due to the heat convection, the wall temperature of the channel usually varies along the streamwise direction.

Preconditioning complex symmetric linear systems [PDF]
, 2014 A new polynomial preconditioner for symmetric complex linear systems based on Hermitian and skew-Hermitian splitting (HSS) for complex symmetric linear systems is herein presented. It applies to Conjugate Orthogonal Conjugate Gradient (COCG) or Conjugate

An improvement of the Euler–Chebyshev iterative method
Journal of Mathematical Analysis and Applications, 2006 AbstractWe present a new method for the computation of the solutions of nonlinear equations when it is necessary to use high precision. We improve the Euler–Chebyshev iterative method which is a generalization of an improvement of Newton's method. A symbolic computation allows us to find the best coefficients respect to the local order of convergence ...

Numerical Studies for Fractional-Order Logistic Differential Equation with Two Different Delays
Journal of Applied Mathematics, 2012 A numerical method for solving the fractional-order logistic differential equation with two different delays (FOLE) is considered. The fractional derivative is described in the Caputo sense. The proposed method is based upon Chebyshev approximations. The

Chebyshev Polynomial Approximation for Distributed Signal Processing [PDF]
, 2011 Unions of graph Fourier multipliers are an important class of linear operators for processing signals defined on graphs. We present a novel method to efficiently distribute the application of these operators to the high-dimensional signals collected by ...

Overview of Precoding Techniques for Massive MIMO
IEEE Access, 2021 Massive multiple-input multiple-output (MIMO) is playing a crucial role in the fifth generation (5G) and beyond 5G (B5G) communication systems. Unfortunately, the complexity of massive MIMO systems is tremendously increased when a large number of ...

Spectral Methods for Numerical Relativity. The Initial Data Problem [PDF]
, 1999 Numerical relativity has traditionally been pursued via finite differencing. Here we explore pseudospectral collocation (PSC) as an alternative to finite differencing, focusing particularly on the solution of the Hamiltonian constraint (an elliptic ...

Performance Evaluation of Short Packet Communications in NOMA VLC Systems With Imperfect CSI
IEEE Access, 2022 In this paper, we analyze and evaluate the impacts of imperfect channel state information (CSI) of the short packet communication (SPC) in a non-orthogonal multiple access (NOMA) visible light communication (VLC) system.
