## The positivity of operators in Hilbert spaces is an important concept finding wide application in various branches of Mathematical System Theory. A frequencydomain condition that ensures the positivity of time-varying operators in L2 with a state-space description, is derived in this paper by usi

A standing wave in front of a seawall may reach a height more than twice of its incident component. When excess pore pressure occurs, it may even induce seabed instability, hence endangering the structure. This issue was studied previously using only linear wave theory. In this paper, standing-wave
Based on the two-port describing function characterization, frequency domain stability conditions are derived for non-linear two-port amplifiers. The conditions are applied to the case of a tuned transistor amplifier with saturated class-C type transfer characteristic. The theoretical considerations
