Acceleration of convergence in solving the eigenvalue problem by matrix iteration using the power method
A modification of the matrix iteration using the power method, in conjunction with Hotelling deflation, for the solution of the problem K.x = ω².M.x is here proposed. The problem can be written in the form D.x =λ.x, and the modification consists of raising the matrix D to an appropriate power p …

Creating a Comparative Map of Relative Power for DC ARC Flash Methodologies
… equation outlined in the NFPA70E, the Maximum Power Method, does provide engineers with a formula to calculate DC arc flash incident energy but as the NFPA states this can be quite conservative. However, the NFPA70E also mentions a Detailed Arcing Current and Energy Calculations Method which …

An Empirical Comparison of Four Data Generating Procedures in Parametric and Nonparametric ANOVA
… to empirically investigate the Type I error and power rates of four data transformations that produce a variety of non-normal distributions. Specifically, the transformations investigated were (a) the g-and-h, (b) the generalized lambda distribution (GLD), (c) the power method, and (d) the Burr …

A Comparison of Methods for Generating Bivariate Non-normally Distributed Random Variables
… speed and simplicity. They are the Fleishman Power Method, the Fifth-Order Polynomial Transformation Method, and the Generalized Lambda Distribution Method. Simulations were run in order to compare the three methods by how well they generate bivariate distributions with the desired means, …

Technology for facilitating and analyzing interviews in large groups
… between data gathering and student feedback. The power method of eigenvalue analysis was used to rank student evaluations of leadership effectively and robustly, yet provided insufficient feedback for students. Revising the activity to focus on visioning and collaborating resulted in a more …

Linear stability analysis of non-reacting and reacting elliptical jets
… For the circular jet, the Michalke's shooting method has been extended to the case with a swirling basic flow. For the elliptical jet, an algebraic eigenvalue problem has been formulated by applying the Chebyshev and Fourier spectral collocation method to the disturbance equations of the flow …

Mean capacity of both equal power and water-filling increased as the signal to noise ratio (SNR) is increased. The difference between these two capacities is that the equal power method has no knowledge about …
