A Stability Assessment Methodology
IEEE Power Engineering Review, 1986Weak transmission boundaries are shown to cause steady state and transient stability problems. The weak boundaries are defined by a loss of controllability property of the transient stability model. The loss of synchronism for fault contingencies can occur across these weak boundaries [7] if this boundary is weak compared to the other cutsets that ...

Optimization of a Stability Bound
SIAM Review, 1993The paper deals with the following question. Let \(A\in \mathbb{R}^{n\times n}\) be an asymptotically stable matrix. What is the ``largest'' \(\Delta A\) such that \(A+\Delta A\) remains stable? Letting \(V= x^ T Bx\) be the Lyapunov function for \(\dot x= Ax\), where \(B= B^ T>0\), and using one of the two Lyapunov equations \(A^ T B+ BA+ C=0\) or ...

It is, of course, well known that the usual output stabilization problem, asking about the existence of a constant feedback gain that stabilizes the system, does not have a especially clean answer. Here we describe an alternative version involving the existence of time-varying gains. The problem is this.

Cereal Research Communications, 1997
A new descriptive method for stability estimation based on genotype’s ascending ecological row was proposed. Dynamic meanings of an analyzed agronomic character-dynamic descriptive row and dynamic descriptive statistics were calculated. The proposed statistics estimated stability to the average level and variability of the studied trait.

A stabilized electronic multiplier
Transactions of the I.R.E. Professional Group on Electronic Computers, 1952Many people engaged in the development of precision analog computing equipment have concluded that the two most useful computing circuit elements are a stabilized d-c amplifier and a high-speed precision switch. The first requirement is met by a circuit disclosed by Goldberg.1 A method of stabilizing a large number of d-c amplifiers with a single pulse

A Stabilized Cuboctahedron Frame
International Journal of Space Structures, 1992When one quarter of the vertices and half the edges of an octet truss are removed systematically, the remaining vertices form a lattice complex known among crystallographers as the J-complex, because their spatial configuration resembles that of jackstones.

Business Horizons, 1972
Abstract Organizational adaptability and stability are often viewed as opposites. It is the authors' view that they should be treated as independent concepts and that the relative effectiveness of organizations depends upon their ability to operationalize both.

A Stabilized Switching Ignitron
IEEE Transactions on Nuclear Science, 1964Ignitrons switching high-current pulses are troubled by arc transfer to the wall. An ignitron was made with the anode closer to the cathode (1 cm) than to the wall (3 cm). It was tested successfully as a capacitor-bank crowbar (clamp) tube at 12 kv with two different current wave shapes.

A Stabilized Frequency Divider
Proceedings of the IRE, 1941A method is described for stabilizing the frequency of a relaxation oscillator to any required degree. The stabilized oscillator may be synchronized with a high-order submultiple of a control frequency without any possibility of synchronization at any other submultiple, even if the operating conditions vary widely; the maintenance of synchronization ...
