In this paper the effect of faults in the elements and parts of discrete event systems is investigated. In the occurrence of faults, some states of the system must be changed and some of them must be forbidden. For this goal, different states of these elements are examined and a model for fail-safe behavior of each state is introduced. Replacing new models of the target elements in the prelimin...

The Algorithm2 for a n-link manipulator movement amidst arbitrary unknown static obstacles for a case when a sensor system supplies information about local neighborhoods of different points in the configuration space is presented. The Algorithm2 guarantees the reaching of a target position in a finite number of steps. The Algorithm2 is reduced to a finite number of calls of a subroutine for pla...

An exact algorithm for a n-link manipulator movement amidst arbitrary unknown static obstacles is presented. The algorithm guarantees the reaching of a target configuration of the manipulator in a finite number of steps. The algorithm is reduced to a finite number of calls of a subroutine for planning a trajectory in the presence of known forbidden states. The polynomial approximation algorithm...

This paper presents the study reports of major process involved in a handwritten character recognition system. We focus on the various feature extraction techniques as the recognition mainly depends on the features extraction. After studying the various features we have modified an existing feature extraction technique by introducing two more feature vectors. After the introduction of these two...
