Characteristic exponents of impulsive differential equations in a banach space

International Journal of Theoretical Physics, 1988
Consider the impulsiv differential equation \(dx/df=A(+)x|_{t\neq t_ n}\quad x(t_ u+0)=Q_ nx(t_ n-0)\) in a Banach space X, where A(t), \(Q_ n: X\to X\) are linear bounded and \(t_ n\) are fixed impulsive moments. Let W(t,\(\tau)\) denote the evolutionary operator of the above problem.

Analysis of impulse response characteristics of polymer ultrasonic transducers

NDT & E International, 1988
The impulse response characteristics of polymer ultrasonic transducers were analyzed using the Mason's equivalent circuit. These characteristics strongly depend on material factors of the piezoelectric polymer: the dielectric and mechanical internal loss factors, the electromechanical coupling factor and the acoustic impedance.

Impulse and 60-cycle characteristics of driven grounds — II

Electrical Engineering, 1942
I. Introduction Driven grounds are important in electric power transmission and distribution. In fact, they comprise one of the essential elements in the art of lightning protection. Yet, to this day, the value of protection derived from grounds under actual operating conditions of lightning discharge is difficult to state in full quantitative measure.

DIRECTIONAL CHARACTERISTICS OF IMPULSE RADIATING ANTENNA

Инженерная физика, 2018
Для описания направленности импульсно излучающей антенны предлагается использовать энергетический коэффициент направленного действия и отношение плотности энергии, излучаемой в течение импульса в направлении на точку наблюдения, к плотности энергии на оси антенны.

Servo motor characteristics by impulse testing

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1962
IT IS THE PURPOSE of this paper to suggest the possibility and to consider some of the initial analyses and results of determining certain servo motor steady-state and transient characteristics by impulse testing. If the method can be successfully applied to servo motors, it appears to be reasonable that many other servo and control components could be
