The first part of this paper presents a survey of the literature on automatic handwritten signature verification systems using binary or graylevel images, and focuses primarily on preprocessing techniques, feature or primitive extraction methods, comparison processes, and performance evaluation. With these previous studies in mind, we propose, in the second part of this paper, an image-understa...

This paper tackles the challenging task of developing a simple and accurate analytical model for performance evaluation of WiMAX networks. The need for accurate and fast-computing tools is of primary importance to face complex and exhaustive dimensioning issues for this promising access technology. In this paper, we present a generic Markovian model developed for three usual scheduling policies...

In ad-hoc network, mobile nodes are free to move. They can join or leave the network at any moment of time. Due to this dynamicity, working of network may gets disturbed affecting network performance in terms of throughput, delay, fairness. Considering this we have to focus on various parameters of mobile node. This paper focused on speed and packet drop of mobile nodes. Obtained result is usef...

The fairness of performance evaluation is a concern for all professions, and the appraisal of research output is of particular interest to business scholars and academic administrators. We describe research assessment as a process of social construction that is heavily influenced by journal valuation in business schools. Using journal quality data from multiple sources, we empirically investiga...

this paper proposes a new method of gain scheduling control design for a nonlinear system which is described as linear parameter varying form. a performance measure based on linear matrix inequality is introduced. to consider stability and performance measures in design process, the h∞ loop-shaping method is used to design the local controllers, which can be described as state feedback observer...
