This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...

Assuming the existence of an eV scale sterile neutrino, we develop a 3 + 1 neutrino mass model using A4 × Z4 Z2 symmetry group. Three Higgs fields \(H, H^{\prime }\) and \(H^{\prime \prime are considered to give desired matrix which generates non-zero

In the present investigation an attempt has been made to increase therapeutic efficacy, to reduce frequency of administration and to improve patient compliance by developing a sustained release matrix tablets of isosorbide-5-mononitrate. Sustained release matrix tablets of isosorbide-5-mononitrate were developed by using different drug: polymer ratios, such in F1 (1:0.75), F2 (1:1), F3 (1:1.5),...

Let $\mathcal{H}$ be an arrangement of hyperplanes in $\mathbb{R}^n$ and $\operatorname{Perv}(\mathbb{C}Cn,\mathcal{H})$ the category perverse sheaves on $\mathbb{C}^n$ smooth with respect to stratification given by complexified flats $\mathcal{H}$. We give a description $\operatorname{Perv}(\mathbb{C}^n, \mathcal{H})$ terms “matrix diagrams”, i.e., diagrams formed vector spaces $E\_{A,B}$ labe...

In this article we provide a solution to the mixed H 2 =H 1 problem with reduced order controllers for time-varying systems in terms of the solvability of diierential linear matrix inequalities and rank conditions, including a detailed discussion of how to construct a controller. Immediate specializations lead to a solution of the full order problem and the mixed H 2 =H 1 problem for linear sys...

Simple upper bounds for the spectral radius of an H-matrix and a block H-matrix are presented. They represent an improvement over the bounds in [T.Z. Huang, R.S. Ran, A simple estimation for the spectral radius of (block) H-matrices, Journal of Computational Applied Mathematics, 177 (2005), pp. 455–459].

A way to compose a matrix P and a finite dimensional representation ρ of C via a map h into a new matrix P ∗h ρ is defined. Several results about the spectrum, eigenvectors, kernel and rank of P ∗h ρ are proved.
