In FACTS devices various auxiliary signal are used for damping the Oscillations. These signals may be Deviation in Active power, Reactive power to TCR-FC bus, Deviation in frequency, derivative of Active power, Reactive power etc. In this paper various auxiliary signals are compared at a very simple model.

The study of path properties of stochastic processes is a very active area of probabilistic research, where it is of considerable interest to find necessary conditions and sufficient conditions for the regularity of the trajectories of a stochastic process. (1-4,5-10) In Ref. 4, we proved that every random function holomorphic in mean on an open subset D of the complex field is equivalent to a ...

The Chinese hawthorn (Crataegus pinnatifida Bge. var. major N.E.Br.) is uniquely originated in northern China. The ecological and horticultural importance of Chinese hawthorn is considerable and some varieties are valued for their fruit or medicine extracts. Its taxonomy and phylogeny remain poorly understood. Apart from general plant morphological traits, pollen is an important trait for the c...
