the austenitic stainless steel (ss) has been used as a material for  building  ultra  high  vacuum  (uhv)  chamber.  recently significant  efforts  have  been  concerned  a  comparing  the standard  cleaned  for  ultra  high  vacuum,  passivity  stainless. in  this work austenitic  nanocomposites were  synthesize by sol-  gel method. the morphologies  and  topographies  of  the samples  have  b...

Introduction The first part of the paper presents several properties of saddle point matrices with two vector blocks. In these block matrices, the top-left block is a real square matrix , the topright block is the column vector with all entries , the bottom-left block is transposed, and the bottom-right block has the single entry . If is symmetric, the saddle point matrix can be interpreted as ...

In the Standard Model, the origin of CP-violation lies in the charged weak interaction sector, which involves transitions amongst quarks of different flavor and charge through the emission of a virtual W . The coupling strengths of these transitions for the 3 generations of quarks form a 3×3 matrix first introduced by M. Kobayashi and T. Maskawa and known as the (CKM) matrix. The CKM matrix is ...

ABSTRACT: Camel milk contains sufficient levels of insulin and does not form the coagulum in the stomach preventing degradation of insulin and act as an effective vehicle to take the milk insulin unchanged to the intestine. In present study direct spectroscopy and standard addition method, well-known methods in analytical chemistry were used for determining insulin concentration in camel milk. ...

Standard shear samples used for piezoceramic characterization lead to underestimation of the piezoelectric shear coefficients due to its dynamical clamping at resonance. This work presents the application of Alemany et al. ́s automatic iterative method to the resonance of a non-Standard shear sample, in order to determine the related complex parameters of piezoceramics, thus including losses, fr...

If the Standard Model explanation of CP violation is correct, then measurements of CP-violating asymmetries in B meson decays can in principle determine the entire quark mixing matrix. According to the Standard Model (SM), CP violation arises from the fact that in the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix, some of the elements are not real. This picture of CP violation will be inc...

Matrix completion is a widely used technique for personalized recommender systems. In this paper, we focus on the idea of Bounded Matrix Completion (BMC) which imposes bounded constraints into the standard matrix completion problem. It has been shown that BMC works well for several real world datasets, and an efficient coordinate descent solver called BMA has been proposed in [R. Kannan and Par...

In this paper, efficient one-dimensional (1-D) fast integer transform algorithms of the DCT matrix for the H.265 standard is proposed. Based on the symmetric property of the integer transform matrix and the matrix operations, which denote the row/column permutations and the matrix decompositions, along with using the dyadic symmetry modification on the standard matrix, the efficient fast 1-D in...

The objective is to efficiently evaluate u-resultants for numerical uvalues (such as over a finite field). The u-resultant of n homogeneous polynomials in n + 1 variables is defined to be the multi-variable resultant of these n polynomials and a general linear form in the same variables whose coefficients are represented by the symbols u0, . . . , un. It is shown that the u-resultant can be ext...

The Schur method for computing a matrix square root reduces the matrix to the Schur triangular form and then computes a square root of the triangular matrix. We show that by using either standard blocking or recursive blocking the computation of the square root of the triangular matrix can be made rich in matrix multiplication. Numerical experiments making appropriate use of level 3 BLAS show s...
