摘要：
Currently, various mobile intelligent terminals have penetrated into our daily life. But at the same time, security and privacy issues of mobile intelligent terminals become a serious problem. In this paper, we present an approach to ensure the secure communication between mobile intelligent terminals. Our idea is to restrict that plaintext information can only exist inside mobile intelligent terminals, and any information outside of mobile intelligent terminals must be automatically encrypted. Experimental results show that our approach is efficient, and incur only 2%similar to 3% performance losses.

摘要：
This study has established a 1/184 model of blade root by using finite element software (ANSYS), and analyzed the stress pipeline and errors of this blade root model. By transforming the loads in blade root and imposing axial step load, especially by analyzing models boundary conditions and the structure of contact surface, the axial stress, bending stress and the other parameters have been acquired.

摘要：
Missing data universally exists in various research fields and it results in bad computational performance and effcet.In order to improve the accuracy of filling in the missing data,a filling missing data algorithm of the nearest neighbor based on the cluster analysis is proposed by this paper.After clustering data analysis,the algorithm assigns weights according to the categories and improves calculation formula and filling value calculation based on the MGNN (Mahalanobis-Gray and Nearest Neighbor algorithm) algorithm.The experimental results show that the filling accuracy of the method is higher than traditional KNN algorithm and MGNN algorithm.

摘要：
The generalized Wonham controllable canonical form in multi-input systems is presented and applied to pole placement of state derivative feedback. A new direct algorithm is proposed. The multi-input system can be decomposed some single-input systems and for every single-input system the problem is easy to be resolved. The advantage of this algorithm is no need to compute the characteristic polynomial of the system. The theory and approach are introduced, and the general expression containing arbitrary parameter is obtained for the derivative feedback gain matrix of the multi-input system. An illustrative example is presented to show the proposed method.
摘要：
Let Diag(G) and D(G) be the degree-diagonal matrix and distance matrix of G, respectively. Define the multiplier Diag(G)D(G) as degree distance matrix of G. The degree distance of G is defined as D'(G) = Σ x∈v(G)dG(x)Dg(x), where dg(x) is the degree of vertex x, DG(x) = Σ∈V(G)d G(u,x) and dg(u,x) the distance between u and x. Obviously, D'(G) is also the sum of elements of degree distance matrix Diag(G)D(G) of G. A connected graph G is a cactus if any two of its cycles have at most one common vertex. Let G (n, r) be the set of cacti of order n and with r cycles. In this paper, we give the sharp lower bound of the degree distance of cacti among G (n,r), and characterize the corresponding extremal cactus.
