Human motion tracking from monocular video has received increasing attention in recent years due to its broad applications. Among these human motion tracking methods, the particle filter is considered as an effective approach for human motion tracking. However, there are still two limitations of current particle filter approaches such as the prior used for the filtering step is often poor due to relatively...
Automatic age estimation relying on human facial images is a key technology of many real-world applications, which is still a challenging task in the computer vision field. There are three cascade modules for facial age estimation: facial aging feature extraction, dimension reduction (or feature selection) and estimation method. Many existing literatures focus on the first or last module while for...
This paper presents a novel method for electric vehicle charging station planning based on weighted Voronoi diagram. First, the traffic flow of each intersection node is used to represent the road network traffic. The number of charging stations is estimated in accordance with the capacity of conventional-standard charging station. The initial locations are determined by using coordinate method. Then,...
Since the grid structure of 10kV distribution network has always been in a complex and chaotic state, this paper did some research to effectively standardize it. Firstly, the backbone grid and the secondary grid of 10kV distribution network are presented and defined. Then, based on the grid structure and functional characteristics of secondary grid, three types of analysis models are established to...
Adaptive cruise control (ACC) system is a Driver assistant system, which can provide safe and comfortable driving. Based on the analysis of ACC system, a parameter self-tuning fuzzy-PID algorithm is developed to design the ACC control strategy. According to the traffic condition, the parameters of PID controller are adapted on-line by fuzzy rule. The simulation results show that the parameter self-...
We all have a large amount of data stored in Gmail, Facebook, Twitter, Google Docs and many other online services. With the increasingly importance of these online data, we need an effective way to protect it. This paper proposes a personal data storage system, UPDS, to improve personal data's availability and durability. Two common approaches to improve availability and durability are complete replication...
Spatial clustering is an important area in cluster analysis. Up to now, most computing models are implemented mostly by traditional von Neumann's architecture. The purpose of this paper is to propose a simulated evolutionary DNA computing model and integrate DNA computing with cluster analysis. The proposed technique will apply for large scale, high parallel clustering problems potentially.
Since China joined the WTO, the Chinese telecom market has been transformed from a seller's to a buyer's market due to the new competition pattern and booming telecom technology. Therefore, the telecom industry must transform their production centered operations to custom service centered operations. During this process, it is very important to develop new business models and lower operational costs...
Most existing evolutionary algorithms are only effective for optimization problems with no more than one hundred decision variables. However, many optimization problems involve more than several hundreds decision variables, even one thousand. To deal with these problems, a fast cooperative coevolutionary particle swarm optimizer (FCPSO) is proposed, which is constructed based on cooperative coevolutionary...
In the light of the development of energy performance contracting (EPC) in our country, the writer systematically studies the policy, market, financing, running and benefit risk which are existing in the process of the development of EPC. On the basis of it, the target system of risk evaluation on EPC is discussed, quantitative evaluation is conducted by applying theory of indistinct integrated evaluation,...
In this paper we suppose the formation and evolvement mechanism of city system is the site selection of special entities in the city. We construct model to simulate the mechanism based on multi-agent system, the experiment results show that the distribution of a virtual city system can be generated by the mechanism. Further, we prove that the generated distribution of city system is corresponding...
A decision making model for ship collision avoidance is developed in this paper by use of the information fusion methods. The model consists of two kinds of agents, ship agent and VTS agent, and three fusion levels, original data fusion level, multiple union fusion level and distributed plan fusion level. With this model, a final collision avoidance plan with less inconsistent and more economic than...
Traffic flow models had become an important tool for modeling the operations of dynamic traffic systems. Different traffic flow model had its advantage and disadvantage. While microscopic simulation models provided a more detailed representation of the traffic process, were macroscopic and mesoscopic models able to simulate traffic dynamic of large networks in lesser detail, but without the problems...
