Rapid, reflex-like stepping movements are a prevalent and functional compensatory reaction to destabilization, however, little is known about the underlying control. In this paper, a model is developed to examine how speed and stability demands affect control of foot placement during forward and backward compensatory stepping reactions. The concept of the velocity stability margin (VSM) is intr...

This paper focuses on the DC noise margin analysis and read/write failure analysis of the proposed 8T low power SRAM cell. In the proposed structure two voltage sources, one connected with the Bit line and the other connected with the Bit bar line for reducing the voltage swing during the switching activity. These two extra voltage sources will control the voltage swing on the output node and i...

This paper presents the analysis of dynamic noise margin of proposed 8T static random access memory (SRAM) cell. The proposed SRAM cell has two voltage sources, one connected to the bit line and the other is connected to bitbar line. These voltage sources are used to reduce the swing voltage at the output nodes. This reduction of swing voltage causes the reduction in dynamic power dissipation o...

In the category of stable dcpo's, free constructions w.r.t. algebraic theories exist. From this, we obtain various stable power domain constructions. After handling their properties in general, we concentrate on the stable Plotkin power construction. For continuous ground domains, it is explicitly described in terms of saturated compact sets. In case of algebraic ground domains, this descriptio...

Problem statement: Modern power system consists of the complicated network of transmission lines and carries heavy demand. Thus they cause in the stability problem. Approach: Static Synchronous Series Compensator (SSSC) is a power electronic based device that has the capability of controlling the power flow through a line. The series voltage injection model of SSSC is modeled into power flow eq...

This paper presents high speed and low power full adder cells designed with an alternative internal logic structure and Gate Diffusion Input (GDI) logic styles and hybrid CMOS logic style that lead to have a reduced Power Delay Product (PDP). The main design objective for this adder module is not only providing low-power dissipation and high speed but also full-voltage swing. In the first desig...

The paper describes a new method to generate the reactance reference for a TCSC, which has been installed in order to provide damping in a power system. The knowledge of the expected oscillation frequency in the power system is used to create a coordinate system, which rotates with that frequency. In this coordinate system a phasor representing the power swing is being extracted from the input ...

We define the notion of a power stable ideal in a polynomial ring R[X] over an integral domain R. It is proved that a maximal ideal χ M in R[X] is power stable if and only if P t is P primary for all t ≥ 1 for the prime ideal P = M ∩ R. Using this we prove that for a Hilbert domain R any radical ideal in R[X] which is a finite intersection G-ideals is power stable. Further, we prove that if R i...

Recent investigations have focused on the use of active phase imbalance schemes using series connected FACTS devices for subsynchronous resonance (SSR) and power swing damping. This paper compares the effectiveness of TCSC and SSSC based single phase compensation schemes with the corresponding three phase schemes. Controllability of swing modes as well as torsional modes is compared by using a ...

Complex dynamics in the reduced swing equations of a power system are investigated. As the change of bifurcation parameter μ, the system exhibits complex bifurcations, such as saddle-node bifurcation, Hopf bifurcation, cyclic fold bifurcation and torus bifurcations and complex dynamics, such as periodic orbits, quasiperiodic orbits, period-doubling orbits and chaotic attractors which link with ...
