The von Kármán model is the preferred model of continuous gusts for the Department of Defense and the FAA. [1] [2] The model first appeared in a 1957 NACA report [13] based on earlier work by Theodore von Kármán. [14] [15] [16] In this model, the power spectral density of the longitudinal linear velocity component is
This disturbance rejection feature allows users to treat the considered system with a simpler model insofar as the negative effects of modeling uncertainty are compensated in real time. As a result, the operator does not need a precise analytical description of the base system; one can model the unknown parts of the dynamics as internal ...
The control laws may be represented by high order transfer functions required to simultaneously accomplish desired disturbance rejection performance with the robust closed-loop operation. High-gain feedback is the principle that allows simplified models of operational amplifiers and emitter-degenerated bipolar transistors to be used in a ...
A universal three-way trade-off produces adaptive strategies throughout the tree of life, with extreme strategies facilitating the survival of genes via: C (competitive), the survival of the individual using traits that maximize resource acquisition and resource control in consistently productive niches; S (stress-tolerant), individual survival via maintenance of metabolic performance in ...
While earlier nuisance alarms could be set off by small disturbances, like insects or pets, newer model alarms have technology to measure the size/weight of the object causing the disturbance, and thus are able to decide how serious the threat is, which is especially useful in burglar alarms.
The von Kármán wind turbulence model (also known as von Kármán gusts) is a mathematical model of continuous gusts. It matches observed continuous gusts better than that Dryden Wind Turbulence Model [ 1 ] and is the preferred model of the United States Department of Defense in most aircraft design and simulation applications.

The Electronic Disturbance Theater (EDT), established in 1997 by performance artist and writer Ricardo Dominguez, is an electronic company of cyber activists, critical theorists, and performance artists.
A trimmer, or preset, is a miniature adjustable electrical component. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. It is meant to be set correctly when installed in some device, and never seen or adjusted by the device's user.
