Road sign detection and recognition is an important research issue of driver assistance systems. This paper proposes a two-stage automatic detection and recognition algorithm for the most common road signs in China. In the first phase, color segmentation and Hough transform are used for ROI detection. Considering the difference between the actual road signs and standard road signs, the pictograph on road signs is extracted for recognition. Adaptive Hausdorff distance based on similarity weighting is employed in the recognition phase. The experiment results show the effectiveness for recognition and the insensitivity to slight occlusion. © 2008 IEEE.

2008 IEEE International Conference on Robotics and Automation (ICRA 2008), vol.2

作者： Chao Zhou Min Tan Zhiqiang Cao Shuo Wang Douglas Creighton Nong Gu Saeid Nahavandi Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy and Sciences Beijing China School of Engineering and Information Technology Deakin University Geelong VIC Australia

This paper proposes a kinematic modeling method for a bio-inspired robotic fish based on single joint. Lagrangian function of freely swimming robotic fish is built based on a simplified geometric model. In order to build the kinematic model, the fluid force acting on the robotic fish is divided into three parts: the pressure on links, the approach stream pressure and the frictional force. By solving Lagrange's equation of the second kind and the fluid force, the movement of robotic fish is obtained. The robotic fish's motion, such as propelling and turning are simulated, and experiments are taken to verify the model.

Min-max-plus systems are discrete-event systems in which the operations minimum, maximum and addition appear simultaneously. This paper describes a general model of single-input min-max-plus systems and proposes the concept of the state feedback stabilization for these systems. It is derived that the reachable single-input min-max-plus systems can be stabilized using the max-plus linear state feedback. The method based on max-plus algebra is constructive in nature and yields a direct design to achieve the feedback stabilization.

Vehicle type recognition generally refers to identifying the make and model of vehicles through collected images or other information. This paper presents a Two-Dimensional Linear Discriminant Analysis (2DLDA) based algorithm for real time vehicle type recognition. The algorithm is initiated by extracting a region of interest (ROI) relative to the located license plate, and then robust features obtained by performing 2DLDA on the gradients of ROI are used for recognition. Experimental results show that the algorithm can achieve high recognition accuracy (94.7%) and that it is not sensitive to variations of vehicle colors and light conditions. The computational complexity is low so that the algorithm can be implanted in real time.

Artificial transportation systems (ATS) has been related to the study of complex systems and traffic simulation since its birth. Its relationship with complex systems and its connections, as well as differences from traditional traffic simulation systems pose an interesting problem. In this paper, according to two hypotheses about complex systems, we inferred three principles: synthesis, experimentation, and constant experimentation. We explored ATS from the perspective of complex systems, along with a diagram depicting the relationship between ATS-related concepts and methods. We then used the reasoning behind deploying agent-based modeling to explain why the principle of simple objects and relationships can be effective in ATS. We examined these principles from a complex adaptive systems perspective. Finally, essential differences between ATS and traditional traffic simulation systems are reported.

作者： Morteza Montazeri-Gh Mohammad Asadi Systems Simulation and Control Laboratory Mechanical Engineering Department Iran University of Science and Technology Tehran Iran

In this paper, application of the vehicle telematic system in the design of an intelligent HEV control strategy is presented. The system employs a genetic-fuzzy controller that considers the influence of traffic condition on the controller parameters. The proposed intelligent controller is tuned by the traffic data received from the telematic information systems. For this purpose, the concept of the driving cycle is introduced to characterize the driving conditions by several traffic conditions. Accordingly, the application of telematics information for adaptation of the HEV fuzzy-based control system is explained. Finally, simulation results are presented to show the effectiveness of the suggested approach.

Simultaneous Cooling of an Artificial Atom and Its Neighboring Quantum System

We propose an approach for cooling both an artificial atom (e.g., a flux qubit) and its neighboring quantum system, the latter modeled by either a quantum two-level system or a quantum resonator. The flux qubit is cooled by manipulating its states, following an inverse process of state population inversion, and then the qubit is switched on to resonantly interact with the neighboring quantum system. By repeating these steps, the two subsystems can be simultaneously cooled. Our results show that this cooling is robust and effective, irrespective of the chosen quantum systems connected to the qubit.

This paper presents a novel approach in pedestrian detection in static images. The state-of-art feature named histograms of oriented gradients (HOG) is adopted as the basic feature which we modify and create a new feature using boosting algorithm. The detection is achieved by training a linear SVM with the boosted HOG feature. We experimentally demonstrate that our solution achieve comparable performance as the HOG algorithm on the INRIA pedestrian dataset yet considerably reduce storage requirement and simplify the computation in terms of elementary operations.

Quantum entanglement via two-qubit quantum Zeno dynamics

We study the two-particle quantum Zeno dynamics with a type of nondeterministic collective measurement whose outcome indicates whether the two-particle state has been collapsed to ∣11⟩. Such a threshold detection, when used continuously, can lead to nontrivial quantum dynamics. We show that such type of dynamics can be used to produce quantum entanglement almost deterministically. We then numerically show the robustness of the method and we find that the operational errors of the small-angle rotations do not accumulate. We also propose a possible implementation using superconducting flux qubits.
