On a new criterion for the H-matrix property
A new criterion for identifying generalized diagonally dominant matrices (GDDM, or H -matrices) was given in [K. Ojiro, H. Niki, M. Usui, A note on a new criterion for the H -matrix property, J. Comput. Appl. Math. 150 (2003) 293–302], where the criterion is effective when the given matrix is irreducible. However, when the matrix is reducible, it may lead to a false answer. In this work, to ove...
متن کاملA New Criterion for Screening Medical Applicants
Introduction. In the current screening system, new admissions are based on general intelligence as measured by universities entrance examination. Considering the fact that an important function of medical graduates is to educate the patients how to restore and take care of their health, communicative competence and skills would be, at least, as important as general intelligence. To show that la...
متن کاملCritical to the H-index as a criterion for evaluation at universities
The use of scientometric indicators to evaluate scholar articles and scientist in academic settings is one of the most challenging topics.(1) These indicators can be influenced by diverse and different factors, including the context in which the assessment activity is performed to measure the productivity and publications of the scientist or scholar. One of these indicators, which is currently...
متن کاملA criterion for the half-plane property
We establish a convenient necessary and sufficient condition for a multiaffine real polynomial to be stable, and use it to verify that the half-plane property holds for seven small matroids that resisted the efforts of Choe, Oxley, Sokal, and Wagner [5]. In recent years, matroid theory has found connections with certain analytic properties of real multivariate polynomials. These properties are ...
متن کاملA new iterative criterion for H-matrices: The reducible case
H-matrices appear in various areas of science and engineering and it is of vital importance to have an Algorithm to identify the H-matrix character of a certain matrix A ∈ Cn,n. Recently, the present authors have proposed a new iterative criterion (Algorithm AH) to completely identify the H-matrix property of an irreducible matrix. The present work extends the previous Algorithm to cover the re...
