in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

In this paper, we propose a new optimized PID controller to stabilize the synchronous machine connected to an infinite bus. The model for the synchronous machine is 4-ordered linear Philips-Heffron synchronous machine. In this research, the parameters of the PID controller are optimally achieved by minimizing a definite fitness function to removes the unstable Eigen-value to the left side of im...

This work presents the developed mathematical models of main components and units that are part stabilizer: control panel, gyrotachometer GT46, position sensor, unit, etc. Mathematical armament unit turret with gearbox motor obtained. A model analog digital path horizontal guidance channel is obtained; vertical channel; results modeling modes: for channel, channel. have been developed, which us...

Purpose: The aim of the work was a numerical and experimental analysis of spine’s transpedicular stabilizer on lumbar part of spine. The result of the analysis was determination of displacements of the stabilizers’ elements. Design/methodology/approach: To define numerical characteristic of the lumbar spine – transpedicular spine stabilizer system, the finite element method was applied. Geometr...

A Power System Stabilizer (PSS) is the most cost effective approach of increase the system positive damping, improve the steady-state stability margin, and suppress the low-frequency oscillation of the power system. A PSS has to perform well under operating point variations. Some of the major issues in the application of PSS are the choice of the input signal, the location of the PSS, the contr...

The power system stabilizer is used to damp out the low frequency oscillations that improve the small signal stability of the power system. If ignored these low frequency oscillations may lead to cascaded failure of the complete power system. This paper presents the comparative study of conventional power system stabilizer (CPSS) with newly proposed Adaptive Fuzzy Logic Controlled Power System ...

In 2005 IEEE (The Institute of Electrical and Electronic Engineers) introduced a new standard model for Power System Stabilizers, the PSS4B. This is an advanced multi-band stabilizer that may give a better performance than the regular PSSs often used today. The new stabilizer has three parallel control blocks, each aiming at damping different oscillatory modes or different frequency bands of th...

This paper investigates the relation between linear codes and the stabilizer in GL2(C) of their weight enumerators. We prove a result on the finiteness of stabilizers and give a complete classification of linear codes with infinite stabilizer in the non-binary case. We present an efficient algorithm to compute explicitly the stabilizer of weight enumerators and we apply it to the family of Reed...

We present a new approach to simulate arbitrary quantum circuits on a classical computer. Our technique generalizes the stabilizer formalism, the underpinnings of the Gottesman-Knill theorem, to include arbitrary states and arbitrary quantum operations. The core of our approach is a novel state representation combining the density matrix and stabilizer representations. Obviously, not all simula...
