Book Description
Ce livre concerne les techniques d'indexation dans des bases d'image appliquées à la navigation des robots. Deux types de représentations peuvent ètre construites. D'une part les modèles géométriques 3D; ces modèles permettent de localiser le robot précisément sous la forme d'une position et d'une orientation dans un repère métrique. D'autre part les modèles fondées sur l'apparence, sont obtenues à partir d'une base d'images acquises lors de déplacements effectués de manière supervisée durant une phase d'apprentissage: des techniques d'analyse de données (ACP, ACI) permettent d'extraire les données les plus pertinentes de cette base; ces modèles permettent au robot de se localiser de manière qualitative ou topologique.Le robot se localise en recherchant dans la base d'images, celle qui ressemble le plus à l'image courante.Par ailleurs, nous développons une technique de navigation par RFID (Radio Frequency IDentier) qui utilise la méthode MonteCarlo. Ensuite, nous combinons une perception par capteurs RFID et par capteurs visuels afin d'améliorer la précision de la localisation du robot mobile.

Book Description
Navigation techniques in mobile robotics system have gained significant research interest over the past few years. The mobile robot must be able to navigate through a known or unknown environment based on its necessities and applications. This can be achieved by determining its positions and selecting a suitable motion control. Conventional techniques include landmark or dead-reckoning with excessive number on sensors which increases complexities. Several other researchers have been done using both active and passive Radio Frequency Identification (RFID) Signal but there is still need for a more simple and suitable navigation system. This research has been done to present an effective navigation technique using passive RFID reader and tags. The proposed algorithm provides not only the estimation of the robot position in the environment but also the orientation of the autonomous robot. Polar coordinate system has been adopted on the navigation environment where the RFID tags are placed in a grid-like pattern with constant distance. The research objectives have been fulfilled via simulation and experimental validation through hardware implementation. The experimental results show effective and reliable results and the novelty lies in the use of simple technique to achieve the objectives. As a whole, this work has investigated and analyzed several navigation techniques and adopted the best technique for practical application with satisfactory results.

Book Description
To many readers the book of Ezekiel is a hopeless riddle. We still find many features of the man and his message difficult and sometimes even shocking, if not offensive. The bizarre opening vision catches us off guard and tempts us to stop reading. However, if we persist, and if we meditate long and hard on individual utterances and sign actions, we will discover that despite the strangeness of the man and his utterances, this is the most clearly organized of the major prophetic books. Individual prophecies are clearly marked by headings and often by conclusions. If we persist, we will also discover that from a rhetorical perspective, this priestly prophet knew his audience; he recognized in Judah's rebellion against YHWH the underlying cause of the divine fury that resulted in the exile of his people and the fall of Jerusalem to the Babylonians in 586 BCE. But he also recognized that YHWH's judgment could not be the last word. Because his covenant was eternal and irrevocable he looked forward to a day of spiritual renewal and national restoration. This is the first of two volumes of essays on Ezekiel and his book. The seven general essays and two studies of particular texts in this collection explore the times, the message, and the methods of the prophetic priest.
