Cross-spectral root-min-norm algorithm for harmonics analysis in electric power system
Journal of Measurement Science and Instrumentation, 2012 To avoid drawbacks of classic discrete Fourier transform（DFT）method,modern spectral estimation theory was introduced into harmonics and inter-harmonics analysis in electric power system.Idea of the subspace-based root-min-norm algorithm was described,but

On the spectral norm of Rademacher matrices
We discuss two-sided non-asymptotic bounds for the mean spectral norm of nonhomogenous weighted Rademacher matrices. We show that the recently formulated conjecture holds up to $\log \log \log n$ factor for arbitrary $n\times n$ Rademacher matrices and the triple logarithm may be eliminated for matrices with $\{0,1\}$-coefficients.

THE SPECTRAL NORM OF A CIRCULANT MATRIX
JP Journal of Algebra, Number Theory and Applications, 2018Summary: Let \(\mathbf{x}=(x_0,\ldots,x_{n-1})\in\mathbb{R}^n\), \(\mathbf{C(x)}\) be the corresponding circulant matrix, and \(\|\cdot\|\) denote the spectral norm. We prove that if the matrix \(\mathbf{C}(\mathbf{x})^T\mathbf{C}(x)\geq \mathbf{O}\) (entrywise), i.e., if \[\begin{aligned} \sum^{n-1}_{i=0}x_i x_{i+j-1}\geq\,\,\text{for all}\,\,j=1 ...
