State Observers for Systems Subject to Bounded Disturbances Using Quadratic Boundedness Abstract: Quadratic boundedness is adopted to construct state observers for linear, piecewise linear, and ...

β-Piperidinoethylsulfides are oxidized by m-chloroperbenzoic acid to intermediates containing both N-oxide and sulfone functions. These undergo a Cope-type elimination to a vinylsulfone that can be ...

The problem of impulsive mode elimination for descriptor systems via a structured output proportional and derivative (P-D) feedback is investigated in this technical note. The motivation of solving ...
