MULTI-PATCHES IRIS BASED PERSON AUTHENTICATION SYSTEM USING PARTICLE SWARM OPTIMIZATION AND FUZZY C-MEANS CLUSTERING
Particle swarm optimization Fuzzy c-means Taylor’s series expansion weighted mean Hamming distance Iris recognition system
2017/6/19
Locating the boundary parameters of pupil and iris and segmenting the noise free iris portion are the most challenging phases of an automated iris recognition system. In this paper, we have presented ...
NON-EXISTENCE OF SINGULAR CYCLES IN AQUADRIC DIFFERENTIAL SYSTEM WITH FINE FOCUS OF ORDER THREE
Homodinic heteroclinic centre-focus cr
2007/12/17
The problem of existence or non-existence of singular cycles (or komoclinic loops and keteroclinic cydes as being termed in the modern literature of nonlinear dyndric systems) is one of the most impor...
UNIFORM PERSISTENCE IN DISCRETE SEMIDYNAMICAL SYSTEM AND ITS APPLICATION
Uniform persistencem discrete periodic
2007/8/7
In this paper we consider the uniform persistence of a discrete semidynamical system. We establish the conditions under which the weak persistence implies the uniform persistence. We also apply the th...
ON THE BOUNDEDNESS OF SOLUTIONS,EXISTENCE AND UNIQUENESS OF LIMIT CYCLES FOR A CLASS OF CUBIC DIFFERENTIAL SYSTEM
Boundedness of solutions limit cycle exi
2007/8/7
In this paper, we discuss the boundedness of the solutions, the existence and the uniqueness of the limit cycle of the following cubic differential system: x'=y, y'=-x+δy+a_2xy+a_4x+a_5x~2y. (*) We ob...
