Researchers at the University of Tsukuba employ a modified mathematical technique to make complicated nonlinear equations more tractable, which can lead to more accurate control systems for mechanical ...

The problem of nonlinear filtering is studied asymptotically as the noise tends to zero. Detectability conditions ensuring that the filtering error tends to zero are ...

Imagine standing on top of a mountain. From this vantage point, we can see picturesque valleys and majestic ridges below, and streams wind their way downhill. If a drop of rain falls somewhere on this ...
