The QR decomposition, recursive least squares (QRD RLS) algorithm is one of the most promising RLS algorithms, due to its robust numerical stability and suitability for VLSI implementation based on a systolic array architecture. Up to now, among many techniques to implement the QR decomposition, only the Givens rotation and modified GramSchmidt methods have been successfully applied to the deve...

In this paper, we compare with the inverse iteration algorithms on PowerXCell 8i processor, which has been known as a heterogeneous environment. When some of all the eigenvalues are close together or there are clusters of eigenvalues, reorthogonalization must be adopted to all the eigenvectors associated with such eigenvalues. Reorthogonalization algorithms need a lot of computational cost. The...

With the development of research on educational psychology and foreign language teaching and learning, one of the most controversial concepts in educational psychology might be the issues related to the students’ achievement goal orientations. Regarding the goals that students adopt which might influence their academic success and failure, this study was undertaken to determine whether gender a...

introduction: over the past few decades, two revolutionary approaches have emerged as a new form of medical education: electronic medical education and web-based medical education. a number of well-known medical institutions, such as harvard and johns hopkins used a wide range of cyberspace capabilities to increase their competitiveness. researchers have expressed that cyberspace will change he...

background: eclampsia is associated with 14 % of maternal mortality in developing countries. considering that identification of at risk mothers and improving the level of knowledge and awareness of family care experts would lead to better control of the disease and its complication, the aim of this survey was to evaluate the level of knowledge and attitude concerning this disease among pregnant...
