In this paper, the combination of genetic algorithm and a new variable step-size algorithm for a second-order adaptive IIR notch filter is presented. The objective of the new algorithm is to optimize the filter coefficient. The results of computer simulation show that the new algorithm provides a good performance such as fast convergence rate, low mean square error and noise robustness. In addition, the new algorithm is also applied to cancel 50-Hz power line interference in the recording of electrocardiograms signal.

Global optimal path planning of car-like vehicles remains today an open problem especially in the presence of obstacles. In this paper, we propose a method to obtain the optimal motion of a vehicle considering kinematic and obstacle constraints. We employ an efficient algorithm (CACM), based on cell mapping techniques, to find the optimal motion laws of a car-like vehicle. Simulation results are reported to show the satisfactory performance of the method.

Smart sensors differ from conventional ones in their ability to process a high amount of data close to the source and in the ability to communicate in a bidirectional way. In this article, we show the reasons to make sensors smart, identify the design challenges of the software running on smart sensors, and put forth our software platform. In our solution, we adopt the event-driven components with bidirectional interface and provide alternative scheduling policies for specific applications. This component infrastructure also supports diversity of connections by including a hierarchical communication model. Additionally, we present our solutions to improve the reliability of these software systems.

China railway has been playing an important role in the economical development and has been confronted with the requirement of higher speed, higher capacity of transport, higher degree of safety and higher quality of services. With the development of artificial intelligence, communication, computer, and its related technologies, it becomes feasible to rebuild traditional railway with such advanced technologies in order to resolve the problems mentioned above. China railway had started an informatics-based construction on train planning, dispatching, interlocking and other special fields from early 1980 successively. The conditions are ready for the transformation of railway transportation system to the railway intelligent transportation system (RITS). Establishment of system architecture is the first step to develop the China national RITS. This paper presents the current state of the research and development of information and intelligence technologies in China. On the basis of the discussion about the definitions and goals of China national RITS, the developed principle and the system architecture, which includes service architecture, logical architecture and physical architecture for China national RITS are discussed at the end.

We describe a fast and reliable vision system for detecting and recognizing occupants in automobiles. The main advantage of our system is its high accuracy due to the use of fusion module, which combines the results of multiple classifiers operating on different types of features (edges, scale, and range) from the same image. Another advantage is that since the same image sensor is used to generate the multiple feature types, cost is reduced. We utilize an active illumination strategy to provide adequate illumination car seat and shadow fill-in during both the night and day. Occupant position detection and recognition is performed on the actively illuminated image using the same algorithm under both night and day conditions. Our system can use images from commercially available CMOS vision sensors and thus very cost-effective and efficient for smart air bag applications in automobiles. We have successfully demonstrated this system operating in a test vehicle at real-time video rates (30 updates/sec) with high accuracies for a large variety of situations and lighting conditions.

This paper presents the results from the application of an optimal control discrete-time algorithm to solve the dynamic user equilibrium problem. The underlying traffic model is a macroscopic second order model, which intrinsically represents queue spillback. Results obtained from the application of the dynamic user assignment for a southern part of the Paris highway network are presented.

We propose a macroscopic method, which can perform real-time tracking of moving vehicles on highway. In addition to dealing with the problem caused by occlusion and noise, the proposed method can also track a vehicle doing lane change. The proposed method consists of two phases: the detection phase and the tracking phase. In the detection phase, we use entropy-based features to check the existence of vehicles. Then, we use the flux theory, which is commonly used in fluid mechanics to perform the tracking task. By conducting a great number of experiments, we have demonstrated the efficiency as well as the effectiveness of the proposed system.
