This paper represents using Case-Based Reasoning (CBR) in order to support undergraduate control engineering students for learning nonlinear systems and control applications. CBR is an experience-based problem solving methodology;thus, it is used for helping control engineering students to design conventional PID controllers for nonlinear systems. For this purpose, GUNT pH neutralization process is used as the experimental setup and a GUI is designed for cased-based reasoning in MATLAB. It is observed that undergraduate students can learn and increase their experience on nonlinear systems using the proposed new CBR-GUI. © 2012 IEEE.

Outdoor images captured during inclement weather conditions generally exhibit visibility degradation. Localized light sources often result from activation of streetlights and vehicle headlights and are common scenarios in these conditions. The presence of localized light sources in hazy images may cause the generation of oversaturation artifacts when those images are restored by traditional state-of-the-art haze removal techniques. Therefore, we propose a novel haze removal approach based on the proposed hybrid dark channel prior technique in order to remedy the problems associated with localized light sources during image restoration. The overall results show that the proposed haze removal approach can recover haze-free images more effectively than can the other previous state-of-the-art haze removal approach while avoiding over-saturation.

This paper addresses the stability problem of a class of nonlinear switched systems with partitioned state-space and state-dependent switching. In lieu of the Carathéodory solutions, the general Filippov solutions are considered. This encapsulates solutions with infinite switching in finite time. Based on the theory of differential inclusions, a Lyapunov stability theorem is brought forward. These results are also extended to switched systems subject to polytopic uncertainty. Furthermore, the proposed stability theorems are reformulated using the sum of squares decomposition method which provides sufficient means to construct the corresponding Lyapunov functions via available semi-definite programming techniques. © 2012 IFAC.

M-Bus is a special communication technology for transferring information of consumption measurement instrument and the counter. M-Bus is widely used in data collection in the fields of buildings and industrial energy consumption. City underground pipeline system is huge and the structure is complex. As a result, it is great inconvenient for a daily management and maintenance. With all kinds of sensors, the proposed monitoring system can monitor the temperature of the well environment, the water level, gas leaks, whether workers into the well, alarm information. Moreover, it can be applied in the long distance, multi-collection channel, inflammable and explosive application. Due to the new Bus communication, equipments are supplied with power by Bus. Consequently, the proposed system is manageable and suitable for site conditions which can't afford power supply. The system has high reliability, low cost, a broad prospect and practice value. © 2012 Springer-Verlag GmbH.

This paper presents the analysis, modeling, identification and predictive control of an anaerobic digestion process. The widely adopted anaerobic digestion model ADM1 is used to describe the anaerobic digestion of primary and secondary wastewater sludge. Their feed flow rates constitute two model inputs, which are considered as manipulated variables, while the biogas production rate and its methane content constitute two model outputs (controlled variables). The general control objective is to manipulate the inputs within the operation limits such that a maximum methane production is ensured at all times. A comparison between open-loop and closed-loop control reveals the net advantage of predictive control for optimal rate regulation. © 2012 Dunarea de Jos University.

We consider a realistic wireless sensor deployment strategy by which mobile robot deploys sensor nodes when it moves along the linear backbone network with some branches. Because of its finite load capacity, the robot has to repeatedly move back to the position where all sensors are temporarily stored and reload sensor nodes, which leads to the robot has to travel the path many times and consumes more energy. We present a Shortest Traveling Path for Robot (STPR) algorithm by which the robot can reduce the traveling path and achieve the required coverage. All nodes are stored at the temporary starting point and mobile robot continuously loads sensors and moves to the destination, dropping some sensor to meet the basic coverage and connectivity requirements. The mobile robot arrives at the far intersection and deploys sensors along the branches in accordance with the algorithm rules, and then returns the recent branch when having enough sensors. Otherwise the robot moves back and deploys sensors on the back path. The robot reloads sensors and repeats the deployment process until all the branches and backbone is finished. The paper proves that the algorithm is effective compared with the common methods. Simulation results show that the algorithm effectively reduces the moving distance at the randomly generated network. © 2012 IEEE.
