In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...

1. Desirability Index 1.1 Comparing Experimental Participants to Other Clients We first show that the experimental participants are comparable to regular clients of the dating site. We compare the distribution of the desirability index among experimental participants and regular members of the dating company. Regular members are individuals who used the dating service between January 2005 and J...

Regular grid spatial subdivision is frequently used for fast ray tracing of scanned models. Scanned models feature regular sized primitives, with a regular spatial distribution. Grids have worse performance, than other subdivision techniques, for irregular models without these characteristics. We propose a method to improve the performance of grids for rendering irregular scenes by allowing the...
