This paper presents an adaptive Power System Stabilizer (PSS) using an Adaptive Network Based Vague Inference System (ANVIS). An Adaptive Vague Set Based Controller Power System Stabilizer (AVCPSS) has been evaluated. This AVCPSS is capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbances. A Vague Controller (VC) is synthesized by using ...

This paper proposes a reinforcement learning based SVC controller to improve the damping of power systems in the presence of load model parameters uncertainty. The proposed method is trained over a wide range of typical load parameters in order to adapt the gains of the SVC stabilizer. The simulation results show that the tuned gains of the SVC stabilizer using Reinforcement Learning can provid...

Quench propagation velocity in conductors having a large amount of stabilizer outside the multif i lamentary area is considered. The current redistribution process between the multif i lamentary area and the stabilizer can strongly affect the quench propagation. A criterion is derived determining the conditions under which the current redistribution process becomes significant, and a model of e...

the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

Using styrene as raw material, potassium persulfate as an initiator, beta-cyclodextrin as a stabilizer, polystyrene microspheres were successfully prepared with nice monodisperse feature by means of soap-free emulsion polymerization method. Experimental studies were performed in detail to check the effect of the synthesis process of the microspheres, the stabilizer dosage, monomer concentration...

We generalize the random coding argument of stabilizer codes and derive a lower bound on the quantum capacity of an arbitrary discrete memoryless quantum channel. For the depolarizing channel, our lower bound coincides with that obtained by Bennett et al. We also slightly improve the quantum Gilbert–Varshamov bound for general stabilizer codes, and establish an analog of the quantum Gilbert– Va...

two steps synthetic method for the preparation of a novel emulsion stabilizer called poly(ricineoleic acid-b-ethyleneglycol-b-ricineoleic acid) with average mass molecular weight of 7000 daltons is investigated. in the first step, oligoricineoleic acid with average mass molecular weight of 1800 daltons is synthesized (yield 70%). in the second step, the desired copolymer is  synthesized from th...

This work is concerned with multi-party stabilizer states in the sense of quantum information theory. We investigate the homological invariants for states of which each party holds a large equal number N of quantum bits. We show that in many cases there is a generic expected value of the invariants : for large N it is approximated with arbitrarily high probability if a stabilizer state is chose...

We consider the transformation of Hamilton operators under various sets of quantum operations acting simultaneously on all adjacent pairs of particles. We find mappings between Hamilton operators analogous to duality transformations as well as exact characterizations of ground states employing non-Hermitean eigenvalue equations and use this to motivate a generalization of the stabilizer formali...
