Individuals with schizophrenia, particularly those with passivity symptoms, may not feel in control of their actions, believing them to be controlled by external agents. Cognitive operations that contribute to these symptoms may include abnormal processing in agency as well as body representations that deal with body schema and body image. However, these operations in schizophrenia are not full...

We consider the problem of passivity control for a kind of T-S fuzzy system in the literature [1].We will extend it to the uncertain T-S fuzzy descriptor systems with time-delay in this paper. Generally speaking, a mathematical model cannot be used to exactly describe a dynamical system in practice because it is inevitable to include some degrees of uncertainties in the systems. Moreover, time-...

We propose a novel combination of haptic data reduction with the control architecture of the time domain passivity approach (TDPA) in teleoperation systems for dealing with time-varying delay. The sampling rate of haptic data is typically 1kHz for stability and transparency reasons. This high packet rate as well as the additional data overhead becomes a critical factor for data transmission in ...

Time delayed teleoperation has been one of the first and most challenging topics in robotic control. Although numerous methods have been developed by researchers all over the world during the last two decades, those methods have limitations or need special assumptions to be applied. With the development of the world-wide-web, teleoperation through the Internet sees a bright future. However, the...

In this paper, by using some analytic techniques, several sufficient conditions are given to ensure the passivity of continuous-time recurrent neural networks with delays. The passivity conditions are presented in terms of some negative semi-definite matrices. They are easily verifiable and easier to check computing with some conditions in terms of complicated linear matrix inequality.

--It can be shown tha t the value o f the charge/ radius ratio o f metallic ions determines whether the metal on dissolut ion tends to become passive or not. Us ing this criterion it is possible to clarify the influence o f p H and electrode potential on the occurrence and breakdown of passivity. I N T R O D U C T I O N IN MANY cases a base metal is less reactive than would be expected from its...
