The load frequency control system aims to regulate the in electric power at a normal value with predetermined tolerance limit. In practice, does not always operate optimally, therefore controller is needed be added system. designed variation of combination Proportional-Integral-Differential (PID) controllers standard model PIDTune method consisting proportional (P) controller, integral (PI) dif...

We provide a sufficient condition for a measure on the real line to satisfy a modified logarithmic Sobolev inequality, thus extending the criterion of Bobkov and Götze. Under mild assumptions the condition is also necessary. Concentration inequalities are derived. This completes the picture given in recent contributions by Gentil, Guillin and Miclo.

at first, ground-based circular strip-map synthetic aperture radar (gb-csmsar) and its capabilities is introduced and the received signal model, 2-d frequency spectrum and the azimuth and range resolutions are derived and compared with the linear motion strip-map sar resolutions. because of the stability of the path and speed of antenna in gb-csmsar a frequency domain imaging algorithm is sugge...

The classic Poincaré inequality bounds the L-norm of a function, f , orthogonal to a given function g in a domain Ω, in terms of some L-norm of its gradient in Ω. Suppose we now remove a set Γ from Ω and concentrate our attention on Λ = Ω \ Γ. This new domain might not even be connected and hence no Poincaré inequality can generally hold for it. This is so even if the volume of Γ is arbitrarily...

We study eigenvalues of polyharmonic operators on compact Riemannian manifolds with boundary (possibly empty). In particular, we prove a universal inequality for the eigenvalues of the polyharmonic operators on compact domains in a Euclidean space. This inequality controls the kth eigenvalue by the lower eigenvalues, independently of the particular geometry of the domain. Our inequality is shar...
