At present,effective visualization tools are needed urgently to understand the abundant multi-dimensional data in the science,engineering and commerce field.The traditional multi-dimensional data visualization based on dimension reduction is computation complexity and cannot offer the dimension distribution information of multi-dimensional object,so this paper proposes a new multi-dimensional visualization technique based on right regular polygon of even sides.The reference of the multi-dimensional data space—regular 2k polygon coordinates—in the Cartesian coordinates is defined;dimension reduction algorithm is used to the multi-dimensional object according to the optimization theory,using the minimum of the multi-dimensional object coordinates variation between in regular 2k polygon coordinates and in the multi-dimensional data space as criterion;they are rendered in the two-dimensional space using point cloud.The experiments show that the dimension reduction algorithm is highly efficient and easily implemented and adapts to the aggregation with a great amount of high dimensional data.The visualization method is easily understandable,and it can offer the dimension distribution information effectively and is helpful for common user to view the multi-dimensional data and discover the implicit information in knowledge discovery process,especially in the early stages of it,and has an important role in decision depending on the multi-dimensional data.

This article put forward a design of educational technology network cooperation based on task according to actual situation of some institute educational technology development actual situation.The purpose is to study how to balance resources in different institutes or from different educational technology works, and how to common develop by resource sharing or network cooperation.The model and architecture of educational technology network cooperation are discussed in this paper.We give a description of technology platform features and core module function.Educational technology network cooperating, has made beneficial trial to solve the problem of regional information resources sharing and irrational allocation of Educational technology resources.

The quality of the human beings trained by college schools affect the level of troop’s battle effectiveness in the future. Establishing a scientific and rational appraisal system overall quality of students can promote the comprehensive development of students. In this paper, we use modified Delphi method to establish evaluation index system, then propose a kind of index weights ascertainment method based on the combination of modified Delphi and AHP. We quantitatively determine the evaluation index weights and the inverse proportions of the main evaluation comments’ attitude, so as to establishing the comprehensive quality evaluation model of college student based on modified Delphi-AHP method and completing a comprehensive quality evaluation list for college students. It serves as the theory foundation of the comprehensive quality evaluation system of college students.

In this paper, we study the transportation network flow problem with stochastic flow distribution. According to the stochastic properties of transportation network flows, we first discuss the functional relations between the arcs and the nodes for modeling the transportation network systems, and originally construct an incidence matrix of capacity in the frequency domain. Then a new frequency-domain spanning graph model to analyze the network stochastic maximum flow and the stochastic minimum flow problem is presented. A corresponding algorithm is designed to resolve the model. In our solution, through the mutual transformations of probability functions between time-domain and frequency-domain in our model, the dynamic process of origin-destination flows is analyzed qualitatively; hence the minimum flow and maximum flow are derived quantitatively. An advantage of our approach is that it can handle uniformly both the continuous probability distribution case and the discrete probability distribution case. Numerical experiment results illustrate the feasibility and effectiveness of our approach.
