Currently, the data size of Advanced Metering Infrastructure (AMI) system is leaping rapidly. The traditional data storage solution in most AMI systems utilize Relational Data Base Management System (RDBMS) However, current RDBMS can hardly meet the requirements of high-speed storage, computation and analysis when faced with mass data, which places a huge limit on potential applications. This paper...
Internet has provided many confinement services to all of us, sometime we need compare all the similar services or products to decide which one is the best for us. However, most of current web browsers don't render any comparing function for user. People have to manually extract the information on the pages then compare them. In this paper, first introduce the critical item comparing scheme then we...
The network communication applying network coding, in which the intermediate peers firstly encode the information from source, and then forward the encoded data which will be decoded by the destination peers where the original information gets restored. Previous methods indicate that we can improve throughput and stability of a network, fasten the expanding-velocity of copies, and reduce the download...
This paper studies the network synthesis problem, which is common in the design of telecommunication networks and considers a set of practical constraints, such as arc capacity, node capacity and degree, and hop limit. To obtain the minimum cost for the given traffic flows, we propose a concretized model and a branch and bound algorithm for the problem. A schema based on Lagrangian relaxation is introduced...
This paper presents some control methods of the discontinuous conduction mode for the controlling of a cyclo-converter. In this paper, control methods for the cyclo-converter's AC current-loop are introduced and the unique issues of current control with respect to single phase circuit and three phase circuit under the discontinuous conduction mode are analyzed. Base on this, corresponding compensation...
A novel scheme entitled as Additive Increase Multiplicative Decrease control with the Number of Burst Control Packet (AIMD-NBCP) is proposed. Simulation results show that AIMD-NBCP scheme is efficient at keeping the network stable and enhancing the performance of deflection routing in terms of good-put, burst loss probability as well as fairness index.
Adversaries can easily launch an attack, by taking advantage of the free wireless networking available to the public at many conferences, airports or cafes. Meanwhile in these environments, it is very difficult to identify the adversaries. In this paper, we present a scheme that is designed to defend against potential attacks at a very early stage, in order to minimize the damage to the victims and...
A novel knowledge discovery method to multiple classifier fusion is proposed. In the new method, all base classifiers are viewed as predictors relating to domain knowledge, and they may be allowed to operate in different feature spaces. Then the beliefs assigned to each base classifier are generated automatically from the established decision tables (DTs). For this purpose, two types of belief structures...
Mining association rule is one of the common forms in data mining, in which the critical problem is to gain the frequent itemsets efficiently. The classical Apriori and AprioriTid algorithm, which are used to construct the frequent itemset, are analyzed in this paper. Author finds out that there too many data due to those items repeatedly saved in the AprioriTid algorithm. On the basis of analysis,...
This paper describes a method to determine rigid body motion using straight line correspondences. It is assumed that the body has features in the form of parallel line segments. Our method relies on the observation of two pairs of parallel lines over three frames. By introduction of pl??cker coordinates of a line in R3, the motion of the line is easly modeled, and the line-based computation of motion...
