Specific absorption rate (SAR) is employed here to study the relationship between the radiation of a mobile handset and the Chinese electromagnetic human model (CEMHM) with different resolution. In the paper, 3D anatomically realistic CEMHM models with different resolution are presented by the first time. The highest resolution CEMHM model is built using the Chinese Visible Human (CVH) data set containing...
With the increasingly widespread application of cloud computing, it has become a critical task for researchers to study techniques on cloud safety and standardization. In this paper, hybrid cloud security and fair Resource Allocation related problems are investigated. A security model based on trust negotiation is presented to fit the hybrid cloud environment. Furthermore, fair resource model and...
This paper investigates the problems of robust D-stability and D-stabilization for linear discrete uncertain descriptor systems ties in the whole system matrices cover that in the coefficient matrix E. We assume that the coefficient matrix E is rank-invariant, that is, rank(E) = r ≤ n for all admissible uncertainties. Thus, we consider the robustness analysis problem as two cases: the right-descriptor...
With the increasingly widespread application of computer network, it has become a critical task to detect anomalous behaviors in the field of network security. In this paper we develop an entropy-based statistical approach that determines and reports entropy contents for variables in the Management Information Base. The change of the entropy value indicates that a massive network event or an anomaly...
The time-to-digital converter(TDC) aims to mark an accurate timestamp at the time of input signal comes. The Multi-phase Clock sampling method is an usual way to map the TDC into an FPGA. Traditionally, this method provides a medium accuracy and low resources occupation. In this paper, we present a new architecture of TDC base on the 2-ISERDES in the SelectIO, rather than utilizing the Slice resources...
Four estimators of the directed information rate between a pair of jointly stationary ergodic finite-alphabet processes are proposed, based on universal probability assignments. The first one is a Shannon–McMillan–Breiman-type estimator, similar to those used by Verdú in 2005 and Cai <etal/> in 2006 for estimation of other information measures. We show the almost sure and convergence...
In this paper, in order to solve the problem that based in favor subjective and standards are not comprehensive in the strategic supplier selection, we established the indicator system for the selection of the strategic supplier by quantitative and qualitative methods, and proposed a supplier selection model based on several stage selection and grey relational analysis. Then we got the correlation...
The SSE (streaming (single instruction multiple data) SIMD extensions) instruction set was used to accelerate the finite difference time domain (FDTD) method for the significant improvement on the simulation performance. The numerical results of the SSE acceleration on the multi-CPU workstation have demonstrated that we can obtain around 4 times speedup ratio comparing to FDTD without SSE.
The computation of the singular value decomposition (SVD) of an m ×n matrix A is important in many fields. Many sequential and parallel algorithms such as Jacobi, QR based methods have been proposed. In this paper, we study the one-sided JRS algorithm which is based on traditional cyclic one-sided Jacobi algorithm by using the relaxation technique and give a new method in which the relaxation parameter...
In this paper, predator-prey model of Holling III-function response with nonlinear density dependent was discussed by the differential equation qualitative theory, the properties of equilibrium was analysed and the sufficient condition of existence and uniqueness of the limit cycle was obtained.
To solve the ultrafiltration water plant's contradiction of high flux and membrane fouling in summer when algae was high, and ensure the water plant security and stable, a pilot testing which using immersion membrane as the core of combined process was carried on. The results showed: preoxidation using potassium permanganat and coagulation could efficiently reduce the number of algae, ultrafiltration...
