Impedance Variation in a Coaxial Coil Encircling a Metal Tube Adapter

Autor: Yao Luo, Xinyi Yang

Publikováno v: Sensors, Vol 23, Iss 19, p 8302 (2023)

The impedance change in an induction coil surrounding a metal tube adapter is investigated using the truncated region eigenfunction expansion (TREE) method. The conventional TREE method is inapplicable to this problem as a consequence of the numerica

Approximation Properties of Chebyshev Polynomials in the Legendre Norm

Autor: Cuixia Niu, Huiqing Liao, Heping Ma, Hua Wu

Publikováno v: Mathematics, Vol 9, Iss 24, p 3271 (2021)

In this paper, we present some important approximation properties of Chebyshev polynomials in the Legendre norm. We mainly discuss the Chebyshev interpolation operator at the Chebyshev–Gauss–Lobatto points. The cases of single domain and multidom

On the Convergence Rate of Clenshaw–Curtis Quadrature for Jacobi Weight Applied to Functions with Algebraic Endpoint Singularities

Autor: Ahlam Arama, Shuhuang Xiang, Suliman Khan

Publikováno v: Symmetry, Vol 12, Iss 5, p 716 (2020)

Applying the aliasing asymptotics on the coefficients of the Chebyshev expansions, the convergence rate of Clenshaw–Curtis quadrature for Jacobi weights is presented for functions with algebraic endpoint singularities. Based upon a new constructed
