Design of thinned elliptical antenna arrays of uniformly excited isotropic antennas using particle swarm optimization (PSO), is reported. Thinned arrays can generate directive beam with minimum side lobe level (SLL) without degrading the performance of fully populated antenna arrays significantly. Thinning of elliptical antenna arrays using PSO are optimized with different values of eccentricit...

For any graph G, the Equi-eccentric point set graph Gee is defined on the same set of vertices by joining two vertices in Gee if and only if they correspond to two vertices of G with equal eccentricities. The Glue graph Gg is defined on the same set of vertices by joining two vertices in Gg if and only if they correspond to two adjacent vertices of G or two adjacent vertices of Gee. In this pap...

The Fibonacci cube Γn is the subgraph of the hypercube induced by the binary strings that contain no two consecutive 1’s. The Lucas cube Λn is obtained from Γn by removing vertices that start and end with 1. The eccentricity of a vertex u, denoted eG(u) is the greatest distance between u and any other vertex v in the graph G. For a given vertex u of Γn we characterize the vertices v such that d...

Event-related potential (ERP) studies consistently have described a strong, face-sensitive response termed the N170. This component is maximal at the fovea and decreases strongly with eccentricity, a result that could suggest a foveal bias in the cortical generators responsible for face processing. Here we demonstrate that scaling stimulus size according to V1 cortical magnification factor can ...

this paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (srm) during offline and standstill modes. in this method, the fault signature is differential induced voltage (div) achieved by injecting diagnostic pulses to the motor windings. it will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...

according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...
