In this chapter, we present an autonomous monitoring robot platform for agricultural farms and fields that is built using low-cost off-the-shelf hardware and open source software so as to be affordable for farmers. We provide a review of the current state of the art in autonomous agricultural robots and summarize the challenges that they must overcome. Our work comprises two main components: (1) the system architecture and hardware selected for a fully autonomous agricultural robot platform for automated monitoring and intervention tasks, and (2) the sensor fusion, local planning, and navigation software based on the Robot Operating System (ROS) framework with inclusion of design details and testing results. the challenges faced, solutions tested, and successes achieved with respect to the hardware and software architectures for this robot are presented in the interest of guiding future solutions for autonomous agricultural navigation and planning. We evaluate our approaches in outdoor farm field environments as well as indoor environments serving as an analogue for greenhouse navigation, and show how the properties of the environment affect the accuracy of the mapping and localisation tasks.

In this paper we describe the implementation of a Medical Image Aid system designed for fast access to images based on their semantic content. the raw and processed images are grouped according to image type and image content and are organized in a hierarchy. the data organization in the system consists of a collection of such hierarchies that are used to efficiently store images and other related knowledge. the novelty of our system is that it accepts an arbitrary number of userdefined attributes and other features that characterise the image, as well as image processing algorithms for feature extraction. the system supports different query types and it is capable of searching images using multiple levels of symbolic and quantitative descriptions. this system provides a platform for future research on linking knowledge-based image understanding with content-based image retrieval.

the main aim of this paper is using the obtain transfer function of the macroscopic traffic flow model, as distributed parameter system, to simulate this model (fig. 1), then based on the obtain results characteristics to make analysis and for further works to use all this simulations for the synthesis and analysis of corresponding control algorithms depending of the needed conditions in transportation problem model. Using this exact method we obtain directly the plant transfer function for the traffic flow model viewed as a distributed parameter system. the entire physical phenomenon is presenting through the partial differential equations whose show the distribution in vehicles on the high ways. All the research is devoted on the transfer function result and his control system model. In the presenting paper we shown the verification of the analytical result of the model simulation thought the time and frequency characteristics analysis. Copyright 2008 ACM.

the main aim of this paper is the obtaining of transfer function of the macroscopic traffic flow model using an exact analytical method of solution of the non-linear partial differential equations, presenting the transportation problem model as distributed parameter system. the different analytical methods of solution are shown, some of them giving an exact solution. Using this exact method we obtain directly the plant transfer function for the traffic flow model viewed as a distributed parameter system. the entire physical phenomenon is presenting through the partial differential equations whose show the distribution in vehicles on the high ways. All the research is devoted on the transfer function result because of the control system modeling.

this paper describes our efforts to develop a Digital Fish Simulator (DFS), particularly aiming at creating a controlled kinematic centered environment to further shed light on how to design and control artificial fish robots. Compared to a 3D simulator for autonomous robotic fish by Liu and Hu, an improved body wave equation capable of multimodal swimming motions is adopted in our simulator and artificial swimming data can be further imported enabling various fictive swimming patterns. Furthermore, the swimming data generated from the simulator can directly be fed into the fish robots for verification, and vice versa. Finally, a series of fishlike robots with different mechanical design have been built to validate our well-formed ideas and to reach a new level of performance close to actual fish for real applications.
