In this paper the problem of Fault Tolerant Control (FTC) in the framework of Discrete Event systems (DES) modeled as automata is considered. The approach we follow is the so-called active approach in which the supervisor actively reacts to the detection of a malfunctioning component in order to eventually meet degraded control specifications. Starting from an appropriate model of the system, we recall the notion of safe diagnosability as a necessary step in order to achieve fault tolerant supervision of DES. We then introduce two new notions: (i) “safe controllability”, which represents the capability, after the occurrence of a fault, of steering the system away from forbidden zones and (ii) “active fault tolerant system”, which is the property of safely continuing operation after faults. We show how it is possible to define a general control architecture to deal with the FTC problem by introducing a special kind of automaton, called a “diagnosing-controller”.
In this paper we consider the performance behavior of two protocols: AODV and DSR using TwoRayGround model. We study the routing efficiency of the ad-hoc sensor network and compare the performance of two protocols for...

A motivationally-aware version of the Ecolab system was developed with the aim of improving the learners' motivation. To gain some insight into the effects of motivational modeling on students' affective states, we observed the affect of 180 students interacting with either Ecolab or M-Ecolab. The affective states considered were based on existing coding schemes [10]. The results suggest that the motivationally-aware tutoring system seems to maintain students' delight over time. However, it seems the motivational interventions did not create new "virtuous cycles" of positive affect [10], or disrupt "vicious cycles", where a student persists in a negative affective state.

Local conditional Lyapunov exponents are introduced and plotted in dynamical phase space to visualize the local susceptibility of the Lorenz system driven by chaos and noise signals when the system produces consistent response outputs. The dependence of the distribution of the local conditional Lyapunov exponent on changes in the drive signal is investigated. We consider the existence of multiple basins of consistent response for the same drive signal and the dependence of the basins on the drive signal.
