This paper proposes a generalized space vector pulse width modulation (SVPWM) technique for hybrid multilevel inverters for minimizing total harmonic distortion (THD). The proposed method easily determines the actual location of the instantaneous reference space vector and the corresponding switching sequence of a multilevel inverter. The proposed algorithm offers a novel method for minimizing ...

In this pedagogically structured article, we describe a generalized harmonic formulation of the Einstein equations in spherical symmetry which is regular at the origin. The generalized harmonic approach has attracted significant attention in numerical relativity over the past few years, especially as applied to the problem of binary inspiral and merger. A key issue when using the technique is t...

Abstract. Water diversion systems play crucial roles in assuaging flood risk by diverting and redistributing water within among basins. For drought assessments, including investigations of the effects on river discharge worldwide, explicit inclusion these into global hydrological models (GHMs) is essential. However, such representation remains pioneering stage because complex canal operations i...

It is the purpose of this short note to indicate in which way certain amalgam spaces, deened in the spirit of N. Wiener, can be used to deal with questions arising in generalized harmonic analysis in several dimensions. In some sense these results are natural extensions of corresponding one-dimensional results due to N. Wiener (e.g. Theorem 29 in his book 33i]). Amalgams are taken with respect ...

A new representation of the Einstein evolution equations is presented that is first order, linearly degenerate, and symmetric hyperbolic. This new system uses the generalized harmonic method to specify the coordinates, and exponentially suppresses all small short-wavelength constraint violations. Physical and constraint-preserving boundary conditions are derived for this system, and numerical t...

BACKGROUND Official statistics under-estimate influenza deaths. Time series methods allow the estimation of influenza-attributable mortality. The methods often model background, non-influenza mortality using a cyclic, harmonic regression model based on the Serfling approach. This approach assumes that the seasonal pattern of non-influenza mortality is the same each year, which may not always be...

A new numerical scheme to solve the Einstein field equations based upon the generalized harmonic decomposition of the Ricci tensor is introduced. The source functions driving the wave equations that define generalized harmonic coordinates are treated as independent functions, and encode the coordinate freedom of solutions. Techniques are discussed to impose particular gauge conditions through a...

This paper is devoted to the presentation and analysis of matrix representations of the genetic code. Principal attention is paid to a family of the genetic matrices which are constructed on the basis of Gray code ordering of their rows and columns. This Gray code ordering reveals new connections of the genetic code to: 8dimensional bipolar algebras; Hadamard matrices; golden matrices; Pythagor...
