Linear operators for which T * T and TT * commute. II Let (BN) denote the class of all bounded linear operators on a Hilbert space such that T,*T and TT* commute. Let (BN)+ be those T∈(BN) which are hyponormal. Embry has observed that if T∈(BN), then 0∈ W(T) or T ...
aThe more darkness of pupil region versus other parts and having medium gray level of iris district that limited between pupil (very low) and sclera (very high) levels. So we design a method for detecting these two boundaries.Mathematical morphological operators with a suitable threshold are appli...
There are two cases: the first case is that the noisy background pixels which are supposed to be 0 have intensities other than zero and the second case is that the foreground pixels, which are supposed to be 255 have intensities other than 255. We also notice that even though the ...
Thus, the objectives of the research are: To formalize a mathematical model for the operation process of the e-commerce-oriented ecosystem of the 5Ge base station, the information environment that supports the functioning of independent virtual network segments, in the queuing theory paradigm; To fo...

F Gross - 《Michigan Mathematical Journal》 被引量: 8发表: 1972年 On Finite Groups in Which Cyclic Subgroups of the Same Order are Conjugate We consider finite groups G for which any two cyclic subgroups of the same order are conjugate in G. We prove various structure results and, in part...
Two closed subspaces X,Y⊂H are called compatible if there is an orthonormal basis of H such that X and Y both are spanned by subsets of this basis. This is equivalent to the existence of closed orthogonal subspaces X′⊂X and Y′⊂Y such that X∩Y is orthogonal to both X′,...
- 《Journal of Mathematical Physics》 被引量: 45发表: 1972年 Contributions to the Eigenvalue Problem for Slowly Varying Operators We consider Hermitian operators with kernels which exhibit a slow variation, $K( x - y,\\varepsilon ( x + y )/2 )$. The Wigner transform of such a kernel ...
These models are specially designed to be as physically different as possible from each other providing the analyst with significantly different alternatives. The proposed methodology is validated with two numerical examples. The first example shows the capabilities of the technique with a mathematical ...
