This study developed a self-localization system that uses landmarks and movement to pursue a moving object. Specifically, an omni-directional camera was adopted as a visual sensor and was installed on a robot. The image from the omni-directional camera was processed to detect a landmark (an object), and the robot's distance from that landmark was then measured. These functions allowed the mobile robot to pursue a moving object. The measurement of distance based on the omni-directional image depends on the precise inclination of the camera. Consideration of this factor enabled the measurement of distance of relatively close objects with a high degree of precision. In this study, the effectiveness of this system was investigated by various experiments evaluating the measurement of distance, the movement to pursuit a moving object, and self-localization. The robot demonstrated its ability to recognize a moving object and to measure its distance and its angle in relation to the object. Based on these abilities, the robot could successfully follow a moving object. The robot's ability to recognize its location was seen to be based on its ability to recognize certain landmarks, the functions of which are mentioned above.

In this paper, we developed a terminology tagging system using knowledge in an encyclopedia on *** the encyclopedia we first of all, constructed a terminology tagged corpus. The terminology tag sets consist of category information of terminology and identification in the encyclopedia. The corpus was used to extract context rules and heuristic rules for terminology tagging system and to be as an answer set for evaluating the *** context rules and heuristic rules are automatically extracted from the terminology tagged corpus and heuristic rules according to the syntactic patterns and morphological characteristics. The terminology tagging system uses the context rules, heuristic rules and dictionary of postposition and ending of a word instead of morphological analyzer for faster *** terminology tagging system is evaluated using the tagged corpus and its precision is resulted in 98.0%.

Stochastic process algebras have been proposed as compositional specification formalisms for performance models. A formal analysis method of survivable network was proposed based on stochastic process algebra, which incorporates formal modeling into performance analysis perfectly, and then various performance parameters of survivable network can be simultaneously obtained after formal modeling. The formal description with process expression to the survivable network system was carried out based on the simply introduced syntax and operational semantics of stochastic process algebra. Then PEPA workbench tool was used to obtain the probability of system's steady state availability and transient state availability. Simulation experiments show the effectiveness and feasibility of the developed method.

In this paper, a vision based localization is described. Mobile robots must be able to determine their own position to operate successfully in any environments. The Simultaneous Localization and Mapping (SLAM) problem is the key problem for any autonomous mobile robot. We will consider the positioning system of the autonomous minirobot Khepera II. The system uses different colored cylinder landmarks which are positioned at the corners of the environment. This paper describes development of an analytical model to calculate the robot's position based on a parameter set and the knowledge of the positions of landmarks. By using 2D vision, the robot is able to identify colored landmarks and to extract the centre of each landmark.
