Unlike input deadband, the sandwiched deadband between actuator and plant dynamics is very difficult to be explicitly compensated for due to the proceeding actuator dynamics whose effect may not be negligible. The paper presents a practical way to overcome the design conservativeness of existing methods in dealing with sandwiched deadband. Specifically, a describing function based nonlinear ana...

We consider the diffusive limit of a typical pure-jump Markovian control problem as intensity driving Poisson process tends to infinity. show that convergence speed is provided by Hölder exponent Hessian problem, and explain how correction terms can be constructed. This provides an alternative efficient method for numerical approximation optimal in situations with very high jumps. illustrate th...

Aero-elastic systems, by their very nonlinear nature, frequently encounter Limit Cycle Oscillations (LCOs). An LCO occurs when the system being described reaches a periodic steady state where there is a constant exchange of energy between the various degrees of freedom, in this case: the Aero and Structural components. These LCOs might be benevolent at times, but are not so in most cases. In th...

in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

in [1] we uniquely introduced ultra exponential functions (uxpa) and de nednext step of the serial binary operations: addition, multiplication and power.also, we exhibited the topic of limit summability of real functions in [2,3]. inthis paper, we study limit summability of the ultra exponential functions andprove some of their properties. finally, we pose an unsolved problem aboutthem.

in this paper we study two important concepts, i.e. the direct andthe inverse limit of hyperstructures associated with fuzzy sets of type 2, andshow that the direct and the inverse limit of hyperstructures associated withfuzzy sets of type 2 are also hyperstructures associated with fuzzy sets of type 2.

a label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (ma) by the immobilization of thiolated self-assembled dna sequences on a gold nanoparticles-chitosan modified electrode is constructed. when ma was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...
