where [u.sub.k] is the control vector, [[omega].sub.k] and [n.sub.k] are the vectors of the external signal and parametric perturbations [5, 6], f is a nonlinear function.
During processing, a broad array of sensors measure multiple parameters, including the actual laser output at microsecond intervals, all internal and external signal characteristics, the utilisation rate of the beam source, and the condition of additional components.
Data can be automatically gathered, triggered by time, temperature, or an external signal, with threshold alarms available together with the automatic capture of high, low, and average or user-defined temperature.
Assume that such a system is driven by a periodic external signal that is too weak on its own to induce transitions between the various attractors.
To build their microscopic recorder, Ravi Sheth and other members of the Wang lab modified a piece of DNA called a plasmid, giving it the ability to create more copies of itself in the bacterial cell in response to an external signal. A separate recording plasmid, which drives the recorder and marks time, expresses components of the CRISPR-Cas system.
A de-interlacer enables 1080i and 1080p SDI video sources from multiple fixed-lens, PTZ or ENG-style cameras to be used simultaneously without the need for an external signal converter.
Built-in Advanced Hybrid Processing (AHP) on every input and output means there is no need for external signal processing devices.
They were being excited by some external signal, but the actual response I was seeing was not a gravity wave, but simply the transient response of each of these circuits as they resonated at their not-quite-equal natural frequencies.
Triggering is therefore often initiated by an external signal. For example, consider a target object in a high speed production line, which passes a sensor every five seconds for a period of one second.
So when she says there will be an initiative, it is as much of an external signal as you can get that the SNP are ready for a post-mortem and to move on from the failure of 2014.
It is used to decode transmitted signals into video content from an external signal source to display on the screen of a connected TV or a computer.
The STB connects a TV to an external signal source and transforms the AV signal into video content, which is displayed on the screen.
