The most emerging technologies of vehicular communications is vehicular ad-hoc networks (VANET) that has become part of intelligent transportation system (ITS) and wich is able to support a large applications such as: road safety, Comfort and infotainment applications. The routing mechanism is crucial in supporting ITS due to the highly dynamic topology that characterizes this kind of applications. In this paper, we study and compare a overall performance evaluation of seven ad-hoc routing protocols, including a position based protocol wich is the most functional schemes for VANET. Considering two types of data traffics and depending on certain metrics. NS-2 and VANETMOBISIM are used for performance evaluation. The paper shows the suitable protocol for Quality of Service (QoS) metrics and provides great information about choosing an appropriate routing protocol for large scale network.

In this paper, we consider the problem of delay-dependent stability of two-dimensional (2-D) discrete state delay systems described by the second Fornasini and Marchesini (FM) state-space model. Different from the existing results in the literature, this paper makes the use of the Auxiliary Function-based Summation Inequality, which covers Jensen inequality as a special case. Based on a Lyapunov-Krasovskii functional, a new delay-dependent stability criterion is proposed in terms of linear matrix inequality (LMI). Two numerical examples are given to demonstrate the effectiveness and benefits of the result obtained in this study.

The discrete orthogonal moments and moment invariants are powerful descriptors for image analysis and computer vision. However, until now obtaining moment invariants had always needed much computation time and numerical accuracy, which has not been resolved well. Therefore, the main purpose of this paper is to introduce an efficient set of discrete orthogonal moment invariants, named Improved dual Hahn Moment Invariants (IDHMI). The proposed IDHMI are based on a recursive methods for the computation of dual-Hahn polynomials coefficients. These recursive methods permits the fast and accurate computation of the dual Hahn Moment Invariants. In fact, this new set can be used to extract invariant shape features regardless the change of shape's orientation, size and position. Consequently, a series of numerical experiment are performed in order to evaluate the performance of the proposed moment invariants, with regard to the numerical stability, computational time and recognition accuracy. The theoretical and experimental results clearly show the applicability and the efficiency of the proposed method.

This paper give a novel linear matrix inequalities (LMI) approach to robust H∞ controller design of a bilateral teleoperation system. The errors feedback of the position and velocity control scheme are considered for the master and the slave manipulators. The system is modelled as differential equations with communication time-delay. An improved delay dependent stability criterion is derived by constructing a new augmented Lyapunov-Krasovskii (L-K) functional. We prove that the teleoperation system is stable and has good performance under specific LMIs conditions.

The objective of this work is to explore the use of sound augmented reality in order to enhance the museum visit. We aim to provide an audio guide to immerse the visitor in an audio scene consisting of ambient sounds and comments associated with the exhibits, while minimizing its effort to discover these objects and interact with the sound environment. The first contribution of this work is the implementation the concept proof of SARIM (Sound Augmented Reality Interface for visiting Museum). The second contribution is the modeling of the museum visit augmented by the sound dimension. Inspired from some existing models, the objective is to design a complete and integrated model that includes a representation of the visitor, the soundscape and the navigation parts. The purpose of this model is to facilitate the design of different scenarios based on the concept of audibility zones. The third contribution is the evaluation conducted in a real environment which is the Musée des arts et Métiers (MAM) in Paris. This evaluation has confirmed the usability, as well as the educational and playful positive impact of the audio augmented reality in general, and the SARIM in particular comparing to traditional audio-guides.

This paper proposes the control of the rotor side PWM converter of a variable speed doubly fed induction generator (DFIG) based wind turbine using rotor flux oriented vector control based fuzzy logic in order to control the rotor currents. The fuzzy logic controllers and PI controller are used to control the rotor currents to overcome any disturbance. The simulations are developed in MATLAB Simulink.

Per-pixel revolution mapping is an image-based modeling and rendering technique or IBMR (Image-Based Modeling and Rendering). It consists of generating very convincing revolved surfaces without polygonization effect, which are displayed interactively by the graphics cards. When it is about the interactivity or about the visual quality, this technique produces satisfactory results. When the revolved surface is created, we observed that the texture did not map in a correct way. In this paper, we presented an improvement of the revolution mapping technique to solve the problem related to the texture mapping.

Currently, the amount of statistical linked data available on the Web is exponentially increasing. The need to exploit these data for analytical purposes becomes a priority. Online Analytical Processing (OLAP) presents a powerful solution for such task. However, OLAP systems require the implementation of Extract, Transform and Load (ETL) process. Furthermore, carrying out ETL on web data is time and materialization space consuming. This paper discusses an approach for directly querying the web data stored in RDF format (Resource Description Framework) as part of an OLAP interface through a mapping between MDX (MultiDimensional eXpressions) and SPARQL (Simple Protocol and RDF Query Language) without any materialization. This work proposes a first architecture validated by some scenarios. The obtained results shows the effectiveness of our method.
