Cryptography and biometrics have been identified as two of the most important aspects of digital security environment, for various types of security problems the merging between cryptography and biometrics has led to the development of Bio-Crypto technology. In this paper we propose a cryptography key generating methodology based on graph construction and adjacency matrix of extracted minutiae....

Abstract To solve the problem of fast online analysis distribution network operation safety, an N-1 security method based on minimum isolation area information matrix is proposed. Firstly, model established to describe switch and transformer in all feeders network. Then real-time load used determine total be transferred downstream fault. Secondly, active power margin transfer path described by ...

In this paper, the traditional AGC two area system is modified to take into account the role of AGC as an ancillary service. The concept of DISCO participation matrix is introduced and reflected in the two-area diagram. Simulation studies as well as trajectory sensitivity studies are done, the latter for optimization.

The continuous time Linear Quadratic Regulator (LQR) theory has been implemented in the present work for the design of optimal Proportional Integral(PI) controller for the frequency response enhancement of multi area interconnected power system . The PI controller gains as proportional gain (Kp) and integral gain (Ki) are formulated as the optimal state-feedback gains, corresponding to the stan...

this paper utilises the modified folchi method to assess the environmental impact of coal washing plant, alborz sharghi, north-east iran. in this study, the number of factors designed in the method was slightly modified by focusing on the environmental impact of coal washing operations. in addition, few other factors were designed and added to the previous factors. then, twenty-one values of en...

consider the linear system ax=b where the coefficient matrix a is an m-matrix. in the present work, it is proved that the rate of convergence of the gauss-seidel method is faster than the mixed-type splitting and aor (sor) iterative methods for solving m-matrix linear systems. furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a precondition...
