When Does a Dual Matrix Have a Dual Generalized Inverse?

Generalized inverse of fuzzy neutrosophic soft matrix

Neutrosophy is a new branch of philosophy that studies the origin, nature, and scope of neutralities, as well as their interactions with different ideational spectra. Aim of this article is to find the maximum and minimum solution of the fuzzy neutrosophic soft relational equations xA=b and Ax=b, where x and b are fuzzy neutrosophic soft vector and A is a fuzzy neutrosophic soft matrix. Wheneve...

Design and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

The Dual of a Strongly Prime Ideal

Let R be a commutative integral domain with quotient field K and let P be a nonzero strongly prime ideal of R. We give several characterizations of such ideals. It is shown that (P : P) is a valuation domain with the unique maximal ideal P. We also study when P^{&minus1} is a ring. In fact, it is proved that P^{&minus1} = (P : P) if and only if P is not invertible. Furthermore, if P is invertib...

A generalized dual phase-2 simplex algorithm

Real-life linear programming (LP) problems include all types of variables and constraints. Current versions of the primal simplex method are well prepared to handle such problems efficiently. At the same time, the usefulness of the dual simplex method was thought to be limited to the standard problem though it could be the ideal algorithm in many other cases. For instance, most solution methods...
