We show how to prepare any graph state of up to seven qubits with controlled-Z gates. We also classify simple graphs of up to seven qubits into 45 categories using the concept of connected, non-isomorphic, and non-LC-equivalent graphs. Here, the purpose is to classify them according to several relevant physical properties for quantum information theory. In addition, we propose an efficient entanglement measure for measuring entanglement quantity of graph states.

In this article, the stagnation point flow of nano fluid towards a shrinking sheet in a rotating frame in the presence of magnetic effects(MHD) have been discussed. The governing partial differential equations are simplified using similarity transformations. The simplified set of coupled differential equations are then solved by using an analytical semi numerical method named as homotopy analysis method(HAM).The convergence of the analytical solution has been discussed through -curves and the residual error has been computed. At the end, the analytical solutions have been discussed through graphs for various physical parameters appearing in the problem.

The aim of this paper is to study some properties of K-function introduced by Sharma [14]. Here we establish two theorems which give the image of this K-function under the generalized fractional integral operators in-volving Fox’s H-function as kernel. Corresponding assertions in term of Euler, Whittaker and K-transforms are also presented. On account of general nature of H-function and K-function a number of results involving special functions can be obtained merely by giving particular values for the parameters.

In this paper, I consider the case where the densities of the fluid and the rigid body are equal. It is not about a simplifying hypothesis but actually the evaluations of mistakes gotten rest crucial way on the equality of the densities fluid / rigid. I would come back on this aspect while indicating the difficulties met to call the heterogeneous case    and the necessity to modify the numeric diagram (more precisely to modify the approached characteristic function) to get a result of convergence in the heterogeneous case. The multidimensional analyses of features of the different maillages are proposed.

The problem of Schrödinger’s Cat has figured prominently in the debates about the bearing of quantum physics on our understanding of physical reality. On its basis, various theorists have maintained the quantum physical world exhibits a probabilistically indecisive physical reality. The analysis of the paper that this appeal to quantum reality is methodologically at odds with and disjoint from its underlying approach to quantum theory itself. If there is to be methodological uniformity at this juncture it will have to be along the lines that Einstein always focused—an incomplete hidden factor (perhaps better than “hidden variables”) approach.

In this paper we first obtain curvature tensor and Ricci tensor components of the flag manifold SO(7) U(3). Then we determine the necessary and sufficient condition for this flag manifold to be Einstein.We also completely determine Einstein-like metrics and prove that these spaces are neither locally symmetric nor conformally flat. Moreover, we give all critical points for the energy functional restricted to vector fields of the same length and calculate the energy of an arbitrary invariant vector filed V . The existence of shrinking homogeneous Ricci solitons and the non-existence of Yamabe solitons and harmonic maps are also shown. Also it is proved that in the case that these spaces are Einstein their Ricci tensors are parallel.

This work studies the regularity and gradient estimation of solution of the Cauchy problem for a degenerate parabolic equation  The objective is to improve a wellknown Holder-estimate for the nonlinear parabolic equation and show a geometric structure of the solution. If  is a weak solution, we will prove prove a time-derivatives estimation: for some positive constant  and, where. Furthermore, we also intend to prove that the Holder-index is (0, 1] rather than (0, 1) again for space dimension . Unfortunately, we are afraid we can only give a proving process for the first result in this report because there are a few difficulties for the next two conclusions. Maybe, there are some intrinsically difficulties to finish the left work, and the point is to give a gradient-estimation about space variable x. Although we have got one, we are still not satisfied with it. Therefore, we will explore in the next stage.

In this paper, a kind of multivariate linear q-Stancu operators are dened
on a simplex, which generalize the famous Bernstein operators and Stancu op-
erators. Then the direct, inverse and saturation approximation results of the
iterated Boolean sums of q-Stancu operators are obtained. Moreover, the op-
timal approximation order and the characteristics of these iterated operators
approximating the continuous functions are provided.

                                        Abstract

To answer if need be increasing of the modern societies to evolve in minimal situation of danger, the management of the risks became, since several years, a complementary activity and necessary of the engineering activities in a project or exploitation of an operational system. The research of the safety of facilities either industrial products and of the security of people and goods that results some make part of every citizen's daily life henceforth [8]. 

We propose multidimensional analyses of the risks project management in the case of the synthesis of the results of a spatial system. 

 

Keywords and phrases: Management, risks, risks project, multidimensional analyses.
