MRI phase contrast is a well known technique for computing the average velocity associated to each pixel. In this work, we calculate the exact probability distribution function for the velocity given the noise in the signal. ...

In networked control a channel model is explicitly considered in discrete-time within the classic feedback loop scheme. It is well known by now that the channel model signal-to-noise ratio (SNR) happens to be an important ...

The explicit consideration of a communication channel model in a feedback control loop is known to introduce a fundamental limitation on the feedback control loop stabilisability in the form of a channel signal-to-noise ...

Fundamental limitations in networked control systems (NCS) has been researched for the last years with many results, from a channel transmission minimal rate for stability based on information theory, to an infimal ...
