We consider a multivariate continuous-time process, generated by a system of linear stochastic differential equations, driven by white noise, and involving coefficients that possibly vary over time.

In performing air sampling in the field, the first step is to assemble a sampling train consisting of a calibrated personal sampling pump connected by a piece of plastic tubing to the collection media ...

Real-time sampling oscilloscopes let you see the details of a waveform because they capture details, especially when your waveform isn’t repetitive. Equivalent-time sampling oscilloscopes generally ...

Regularly testing waterways and reservoirs is a never-ending responsibility for utility companies and municipal safety authorities, and generally — as you might expect — involves either a boat or at ...
