Multipath characteristics of impulse radio channels
VTC2000-Spring. 2000 IEEE 51st Vehicular Technology Conference Proceedings (Cat. No.00CH37026), 2002We investigate the multipath characteristics of the impulse radios (IR) which have drawn much attention for future high-speed wireless communication services. For this objective, we observe the characteristics of bit error rates through computer simulations for the deterministic two-path model and the statistical indoor multipath model of Saleh and ...

The Impulse Characteristics of Electrical Insulation Operating at Cryogenic Temperatures
IEEE Transactions on Electrical Insulation, 1981This paper reports the transient voltage breakdown characteristics of electrical insulation operating at cryogenic temperatures. Nomex®e, Tyvek® and polypropylene film/cellulose paper laminate (PPLP) specimens impregnated with liquid nitrogen (LN2) and containing cavities of known dimensions were subjected to either 1.2/50 or 250/2500 ps impulses of ...

Characteristic exponents of impulsive differential equations in a banach space
International Journal of Theoretical Physics, 1988Consider 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, 1988The 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, 1942I. 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.

Servo motor characteristics by impulse testing
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1962IT 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
