We investigate a hybrid electro-optomechanical system that allows us to realize controllable strong Kerr nonlinearities even in the weak-coupling regime. We show that when the controllable electromechanical subsystem is close to its quantum critical point, strong photon-photon interactions can be generated by adjusting the intensity (or frequency) of the microwave driving field. Nonlinear optic...

This paper discusses the controllability problem of gene regulation networks from the systems and control point of view. First, we consider what kind of controllability problems are useful for analyzing and controlling gene networks. Next, based on a probabilistic approach for the controllability analysis of hybrid dynamical systems, this paper provides a method to solve a kind of controllabili...

Given a system with an uncontrollable linearization at the origin, we study the controllability of the system at equilibria around the origin. If the uncontrollable mode is nonzero, we prove that the system always has other equilibria around the origin. We also prove that these equilibria are linearly controllable provided a coefficient in the normal form is nonzero. Thus, the system is qualita...

the interline power flow controller (ipfc) is a concept of the facts controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. this paper proposes a novel ipfc-based damping neuro-control scheme using pso for damping oscil la t i o ns in a power system to improve power system stability. the add i tion of a supplementary controll...

in this work the general aspect and the behavior of a simplified theoretical model for studying mass isolated systems are investigated. the model is in the form of a dual mass model in a single storey arrangement. to find damping ratio and natural frequency of the system, non-classical eigen analysis has been performed on the model. later, time integration analyses subjected to different earthq...

Positioning systems include different control functions for automatic positioning and guidance of marine vessels by means of proper action of the thruster and propeller devices. These may be controllable pitch propeller (CPP) with fixed speed, controllable speed with fixed pitch propeller (FPP), or controllable pitch and speed in combination. The positioning controller computes commanded forces...

Emotional reactions to basic, artificial, yet carefully controllable point-light displays (PLDs) were investigated with ratings of valence, arousal, approachability, and dominance. PLDs were varied by movement location (upper and lower) and intensity (10°, 20°, and 30° angular change) for angular upward and downward movements. Half of participants (N = 28) were told that PLDs were related to fa...

Workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎However, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. Controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

To offer point absorber wave energy converters (WECs) as a bankable product on the marine renewable market, multiple WECs will be installed together in an array configuration. The community (research and industrial) has identified urgent need for available realistic reliable data WEC tests order to perform better optimization approach validate recently developed (non-linear) numerical models. ‘...

The quality of manufactured products is characterized by many controllable quality factors. These factors should be optimized to reach high quality products. In this paper we try to find the controllable factors levels with minimum deviation from the target and with a least variation. To solve the problem a simple aggregation function is used to aggregate the multiple responses functions then a...
