Slow-varying
WebbWhen the exciting frequency is relatively small, by regarding the whole exciting term as a slow-varying parameter, the original system can be transformed into a generalized autonomous system. The phase space can be divided into three regions by the nonsmooth boundaries, in which the trajectory is governed by three different subsystems, respectively. WebbVarying requirements and the complications of international politics meant that progress on the initiative was slow. 不同的要求和国际政治的复杂性意味着该倡议的进展缓慢。 Still in use today , the M198 is, in turn , being slowly replaced by the M777 Ultralightweight howitzer , which weighs nearly half as much and can be more easily moved .

Webb14 juli 2024 · Definition ( Karamata ): A function L ( x) > 0 is called slowly varying if for any λ > 0 we have (1) lim x → ∞ L ( λ x) L ( x) = 1. Definition (Jakimczuk): Suppose that f ( x) > 0, lim x → ∞ f ( x) = ∞, and there exists a continuous derivative f ′ ( x) > 0. The function f ( x) is of slow increase if (2) lim x → ∞ f ′ ( x) f ( x) / x = 0.

Similarly, a regularly varying function is a function of a real variable whose behaviour at infinity is similar to the … Visa mer Definition 1. A measurable function L : (0, +∞) → (0, +∞) is called slowly varying (at infinity) if for all a > 0, $${\displaystyle \lim _{x\to \infty }{\frac {L(ax)}{L(x)}}=1.}$$ Definition 2.

WebbThe terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. http://www.cdam.lse.ac.uk/Reports/Files/cdam-2007-03.pdf
