In classical linear algebra, the eigenvalues of a matrix are sometimes defined as the roots of the characteristic polynomial. An algorithm to compute the roots of a polynomial by computing the eigenvalues of the corresponding companion matrix turns the tables on the usual definition. We derive a firstorder error analysis of this algorithm that sheds light on both the underlying geometry of the ...

islamic architecture has a fundamental dignity and tries to preserve the spiritual and immortal elements. the most sensible characteristic of this type of art is the compatibility with the nature of islam; monotheism, which the mosque architecture provides the best bed for such purpose. the main model for constructing mosques, from both outward and internal spiritual truths point of view, is th...

In this paper, the concept of semi-compatibility and weak compatibility in Fuzzy metric space has been applied to prove a common fixed point theorem. We improve the result of Kumar and Pant [14] by dropping the condition of continuity of the mapping and using semi-compatibility and weak compatibility of the mappings in place of compatibility.

OBJECTIVE Standardization and systematization of data to provide quick access to compatibility of leading injectable drugs used in hospitals for parenteral nutrition. METHODS We selected 55 injectable drugs analyzed individually with two types of parenteral nutrition: 2-in-1 and 3-in-1. The following variables were considered: active ingredient, compatibility of drugs with the parenteral nutr...

In a recent review in TREE [1], Mays and Hill discuss the interface between sexual selection for good genes (i.e. female choice based on traits indicating heritable fitness) and sexual selection for genetic compatibility (i.e. how well the genes of the parents function together in their offspring).We feel that the scopeof their contribution is somewhat limited, primarily because they implicitly...
