Logistics distribution problem is an important part of the modern logistics systemSuppliers need to plan a route scheme for each customer in goods distribution, which is a multiponit to multi-point problemIt is *** analysis of characteristics of the existing logistics system, we construct a mathematical model by introducing the order request and the return request with multiple suppliersWith this model, we present a heuristic logistics distribution algorithm based on parallel multi-colonies, by adding heuristic facor and introducing metrizable ratioSimulation results show that the proposed algorithm is more effective.

The composition of the microemulsion plays a key role in modulating the formation of nanoparticles of inorganic *** order to understand the modulating mechanism,the composition of the middle phase microemulsion formed by Sodium Dodecyl Sulfonate/ 1-Alcohol/n-Alkane/ Water quaternary system was studied by δ-γ phase diagram.A series of phase inversions O/W(2) → B.C.(3) → W/O(2) were observed with the increase in 1-alcohol *** physicochemical parameters,such as the coordinates of the start(β,ε) and end points(β,ε) of the middle-phase microemulsion,the mass fractions of AS(C) and 1-alcohol(C) in the total system,and the solubilities of A(S) and 1-alcohol(A) in oil phase,were *** influences of n-alkanes,1-alcohol and concentration of NaCl solution on the composition of middle phase microemulsion were significantly.

In this paper,the operation of a wind energy conversion system(WECS) incorporating a Double-Fed Induction Generator(DFIG),under various wind speeds and faulty conditions,is investigated through simulationIn this study the simulation of such a system(DFIG-WECS) was held by using the software Matlab/SimulinkThe simulation results are presented and evaluated for the issues of fault diagnosis and identificationMore specifically,a DFIG-WECS has been simulated under various wind speeds and when a short-circuit occurs in the back-to-back converter and in the DC link from the point of view of these issuesIn this work,it has been concluded that the investigated faults have caused a specific and unique harmonic content in grid,rotor and stator phase currents,which could be used for fault diagnosis and identification

Digital urban management has been a fast developing trend in modern cities. And as the development of the urban management, there are an increasing number of people finding that public opinion information is quite valuable and important for this process. So in this paper, we design a public opinion analysis system for urban management information（POASUMI）, in which we implement certain functionalities like public opinion information acquisition, Chinese word segmentation, analysis and statistic of sentiment and hotspot of public opinion information. The experimental results indicate that the results generated by POASUMI can match actual condition very well, definitely providing quite valuable information for urban management.

According to the pervasive applicability problem of PMI(Privilege Management Infrastructure), we make discussions. Through the analysis we state the idea how to solve the aboving problem, and put forward a PMI model that have partly intelligent fundament, I-PMI(Intelligent Privilege Management Infrastructure) model. This model combine with X.509 PMI frame model, UCON usage control model and security knowledge management system(Policy Authority), emphasizing on solving to represent meta-knowledge such as attributes of subject, object and etc, express and manage security policies, and making PMI to have certain knowledge sharing and learning ability.

This paper focuses on the inefficiency in detecting suspicious activities for financial supervision agencies. We propose a hidden group recognition framework to detect suspicious financial subgroups in financial networks. Our algorithm is based on social network theories, constructing financial networks using transaction information among multiple accounts and customers, and also we distinguish two kinds of hidden groups -trusting hidden groups and non- trusting hidden groups. We conduct an experiment using real financial data from financial institutions and the initial evaluation demonstrates the efficiency of this algorithm.
