Research On Flying Animation System Driven by Data

Larger quantities of data about flight performance and flight condition are recorded by flight data recorder (FDR) during the aircraft's flying. It is an importance task to make 3D flying animation from the data on the process of flight data. The design ideas and realizing methods about the software of flying animation system driven by the data from relation database are presented.     

Finite Groups With 52 p Elements of Maximal Order

The authors discuss the finite groups with 52 p elements of maximal order,and get a theorem as follows: SupposeG is a finite group with |M(G)|=52 p elements of maximal order,where p is a prime and p>5,then G is solvable.     

Modularity Design in Customization Marketing of Third Party Logistics

This paper focuses on the key tactics and technology in customization marketing of Third Party Logistics -design modularity of logistics product, which is be researched deeply. The modularity figure of logistics product, and depth management for modularity are constructed by adopting boston Matrix in order to avoid over-customized. Personality customization is realized through making up module differently for Third Party Logistics corporations, to satisfy the demand for customizing and responding the market fast.     

MACHINE PARAMETER IDENTIFICATION AND FAULT DETECTION FOR THE ALTERNATOR SYSTEM

In this paper, the machine( physical) parameters of the alternator system are on-line estimated on the basis of the derived system continuous-tims model, using Recursive Least-squares Estimation and Inverse Calculation Method proposed by Authors. Therefore, the estimated machine parameters can effectively track the changes of their true values and accomplish the fault detection for the alternator system. This paper gives a new way for machne parameter estimation and fault detection of the alternator systems.     

Application of Attribute Reduct Method in Spatial Load Forecasting

Spatial load forecasting is a process distributing the total forecasted load to all partitioned area, and involving more spatial information and more factor influencing application of the future small area, which need a great deal of memory space and longer operation time. Rough set is new method of data analysis. It need not be provided with any advanced information except data set. But attribute reduct is its main algorithms. Division matrix approach on rough set used to reduce the attribute related to land - use decision in order to remove redundancy attribute and then the rules of small area land - use decision is distilled. The method obtained better effect and enhanced the total load forecasting efficiency.     

Data Loading Technology of Data Warehouse

Data warehouse is not the simply data accumulation of operational database. For exerting the function of data warehouse, the construction of data warehouse should be convenient for the data mining and business intelligent work, supply information access, analyze, and share for decision maker. The key to constructing a successful data warehouse is to fully understand the demand of end users from beginning to the end, search and storage data surround users motive closely. This paper first analyzes the data warehouse characteristic and the sort of data component, emphasizes in effective data loading methods and strategies from operational database to data warehouse, gives five sorts data loading methods.     

New Method of Founding Profile Equations and Pressure Angle Formula to the Cylindrical Cam Mechanism with Slide Roller-Follower

According to existent problems on design and application of the cylindrical cam mechanism with the slide roller-follower, the one correct concept about profile design and pressure angle is presented. Based on this concept, the theoretical profile,practical profile,meshing surface equations and pressure angle formula of the cam mechanism are built up by using opp.rotation analysis and offset surface principle. This method is very simple and clear, and avoids the abstract analysing process in meshing principle. The mathematic models built by this paper can be used to design,manufacture and check this type of cam mechanism correctly, and also create conditions to make deeply meshing property analysis of this mechanism.     

Third-party Logistics Subcontract Design Based on Bilevel Programming

The research theme of this paper is about how third-party logistics provider design a kind of effective incentive mechanism which can not only avoid the moral hazard behavior of the subcontractor , but also promote subcontractor to raise the serving performance constantly, until obtaining the best TPL performance .Through building bilevel programming model where constructing the Nash equilibrium model this paper, the anthors assume subcontract decision variable as endogenetic variable first, and then analyze the optimal solution with the restraint of Nash equilibrium at the time of decision variable as exogenous variable, push the subcontract relationship research at the principal-agent level into the lay that principal-agent combining with whole contract performance optimal decision.     

Analysis of Social Appraisal Index System in Public Project

The social evaluation theories of public project still have not been standardization today, and have effects on the process of the construction to city. One of the main reasons lays in that the index system, about the social evaluation theories of public project, connects with many fields, has many non-economic index and difficult in measuring the every index. This article is to mark off the main factors involved in social evaluation effectually, to set up index system of social evaluation practically, and to settle firm ground for methodology and theory of public project.
