During the rough marine environment, heave compensation is used to offset motion of vessel when a crane lifts and lands load. Thus, load are realized decoupled. In previous studies, interference items such as hydraulic cylinder friction, underwater drag force nonlinear friction in active system compensated concentrated be estimated. this paper, we disassembled items; disturbance observer adapti...

This paper deals with the implementation of cascade multilevel inverter-based STATCOM, which employs H-bridge inverter. The STATCOM system is modeled using the d-q transform, which calculates the instantaneous reactive power. In this paper, a power line conditioner using a cascade multilevel inverter is presented for voltage regulation, harmonic filtering and reactive power compensation (var). ...

Glutamine synthetase (GS) regulation in Escherichia coli by reversible covalent modification cycles is a prototype of signal transduction by enzyme cascades. Such enzyme cascades are known to exhibit ultrasensitive response to primary stimuli and act as signal integration systems. Here, we have quantified GS bicyclic cascade based on steady state analysis by evaluating Hill coefficient. We demo...
