Flutter is a dynamic instability of an elastic structure in a fluid flow, caused by positive feedback between the body's deflection and the force exerted by the fluid ...
In electronics and communication, flutter is the rapid variation of signal parameters, such as amplitude, phase, and frequency.Examples of electronic flutter are: Rapid variations in received signal levels, such as variations that may be caused by atmospheric disturbances, antenna movements in a high wind, or interaction with other signals.
A plot of Lorenz' strange attractor for values ρ=28, σ = 10, β = 8/3. The butterfly effect or sensitive dependence on initial conditions is the property of a dynamical system that, starting from any of various arbitrarily close alternative initial conditions on the attractor, the iterated points will become arbitrarily spread out from each other.
For functions of a single variable, the theorem states that if is a continuously differentiable function with nonzero derivative at the point ; then is injective (or bijective onto the image) in a neighborhood of , the inverse is continuously differentiable near = (), and the derivative of the inverse function at is the reciprocal of the derivative of at : ′ = ′ = ′ (()).
[104] [113] [114] The patent, titled Aërial Locomotion &c, described several engine improvements and conceptual designs and included a technical description and drawings of an aileron control system and an optional feature intended to function as an autopilot. [115] [116] In fact, this patent was well known to participants in the Wright ...

Nadya Movchan, CEO of a communications firm, said quitting her coffee addiction made her more energetic and productive at work. Experts weighed in on the impact caffeine can have on the body.
In mathematics, generalized functions are objects extending the notion of functions on real or complex numbers. There is more than one recognized theory, for example the theory of distributions . Generalized functions are especially useful for treating discontinuous functions more like smooth functions , and describing discrete physical ...
