In this paper, the intrinsic material properties of human skin via THz Time Domain Spectroscopy have been investigated in a working frequency range from 0.1-1.5 THz. These measured material parameters are utilized to characterize the channel for inbody nano-networks. The sample for spectroscopic study is the real human skin and repeated measurements have provided consistent refractive index and...

Dynamical evolution of earthquake network is studied. Through the analysis of the real data taken from California and Japan, it is found that the values of the clustering coefficient exhibit a specific behavior around the moment of a main shock: the coefficient remains stationary before a main shock, suddenly jumps up at the main shock, and then slowly decreases to become stationary again. Thus...

In the context of growing networks, we introduce a simple dynamical model that unifies the generic features of real networks: scale-free distribution of degree and the small-world effect. While the average shortest path length increases logarithmically as in random networks, the clustering coefficient assumes a large value independent of system size. We derive analytical expressions for the clu...

Let H be a real Hilbert space and S = {T (s) : 0 ≤ s < ∞} be a nonexpansive semigroup on H such that F (S) 6= ∅. For a contraction f with coefficient 0 < α < 1, a strongly positive bounded linear operator A with coefficient γ̄ > 0. Let 0 < γ < γ̄ α . It is proved that the sequences {xt} and {xn} generated by the iterative method xt = tγf(xt) + (I − tA) 1 λt ∫ λt

From several results in recent years, starting with Hörmander’s characterization of the constant coefficient partial differential equations P (D)u = f that have a real analytic solution u for every real analytic function f , it has become clear that certain properties of the partial differential operator P (D) are equivalent to estimates of Phragmén–Lindelöf type for plurisubharmonic functions ...

The global FOM and GMRES algorithms are among the effective methods to solve Sylvester matrix equations. In this paper, we study these algorithms in the case that the coefficient matrices are real symmetric (real symmetric positive definite) and extract two CG-type algorithms for solving generalized Sylvester matrix equations. The proposed methods are iterative projection methods onto matrix Kr...

Several methods of extracting the magnitude of the real parts of the elastic hadron scattering amplitude-from the experimental data are presented. These methods allows us to obtain the real parts at one definite point of the transfer momentum and with a high accuracy without knowledge of the precise values of the normalization coefficient and with minimum theoretical assumptions.

typographical data entry errors and incomplete documents, produce imperfect records in real world databases. these errors generate distinct records which belong to the same entity. the aim of approximate record matching is to find multiple records which belong to an entity. in this paper, an algorithm for approximate record matching is proposed that can be adapted automatically with input error...

Because of the limitations of existing methods and techniques for directly obtaining real-time blood data, no accurate microflow in vivo real-time analysis method exists. To establish a novel technical platform for real-time in vivo detection and to analyze average blood pressure and other blood flow parameters, a small, accurate, flexible, and nontoxic Fabry-Perot fiber sensor was designed. Th...

Hand gesture recognition possesses extensive applications in virtual reality, sign language recognition, and computer games. The direct interface of hand gestures provides us a new way for communicating with the virtual environment. In this paper a novel and real-time approach for hand gesture recognition system is presented. In the suggested method, first, the hand gesture is extracted from th...
