We consider the problem of assigning houses to agents, where each agent has his own partial ranking of the houses (i.e., a preference list of a subset of the houses). A matching M is Pareto optimal if there exists no other matching M' such that all agents have a house in M' not worse than in M and at least one agent has a better house in M'. In a dynamic market where agents and houses can be added...
A water quality comprehensive evaluation was taken for the water in water supply network. It was on the basis of water supply network microcosmic model. The water quality indicators, by which the state of water quality was expressed, were chosen as the input vector for the comprehensive evaluation model. The self-organizing feature map and k-means arithmetic were taken in the model. As a result, a...
Carbon Fiber-Reinforced Concrete (CFRC), which is also called smart concrete, is a new structural material capable of transmitting information. Its impermeability is a vital factor of the durability. The water infiltrating mechanism in CFRC is analyzed by utilizing hydrostatic process to test the impermeability of CFRC. Experimental results show that CFRC has different impermeabilities with different...
To choose more stable route in Ad Hoc network, it integrated the link stability arithmetic and the principle of the least hop number in route discovery, and proposed link stability Dynamic Source Routing protocol. This protocol chooses route with high link stability, and decreases the number of route interrupted, which results in lower packet loss rate and improves the performance of the network....
In this paper, a technique based on body features is employed to develop a system for sports training, healthcare and medical diagnosis through reusing huge amount of video resources, and extracting useful information from them. This technique realizes the motion capture by using existing video of human motion. The predefined human model is matched and identified with a sequence of videos. The interested...
Network calculus is a new theory of network QoS which is developed recently, it is the application of the Min-Plus Algebra and Max- Plus Algebra in network analysis. With the aim to resolve the transmitting of the real-time dataflow and get a good performance in dataflow waving ,the network calculus theory is applied to the real-time industrial Ethernet. In the paper ,we gained the real-time arrives...
In this paper, a numerical method based on non-polynomial spline functions is presented to solve the one-dimensional heat equation. The new method is unconditionally stable. The accuracy order of the new method is of O(k5+h4),where k and h denote the mesh parameters for t and x, respectively. The accuracy of the present method is much higher than previous known methods.
A variety of cluster analysis techniques exist to group objects having similar characteristics. While there have been recent advances in algorithms for clustering data, some are unable to handle uncertainty in the clustering process while others have stability issues. This paper proposes a new algorithm for clustering data based on rough set theory, which has the ability to handle the uncertainty...
A particular kind of invariants known as moment invariants have been used for object recognition and identification due to its invariabilities under translation, rotation and similitude transformation and approximate invariability even under small-scale perspective transformation, while contours representing shapes and structures play key role in people's tasks of reorganization and identification...
