In order to improve the accuracy of prediction model for the population of preschool children, a new prediction method is provided based on logistic model in this paper. The results show that new prediction model based on logistic model can more accurately predict the preschool population, and distribution of educational resources based on preschool demographic characteristics can effectively develop plans for the state preschool education. © 2017 IEEE.

With the diversification of education and the depth of integration of education and economy, the role of various professional supports for the social economy becomes more and more obvious. As a basic professional, preschool education has been a hot research area in various research teams and government education departments. How to carry on the objective reality, the comprehensive evaluation to the student professional identity, is a major problem which is placed in front of the scientific research personnel. The collaborative filtering algorithm based on neural network optimization, classical statistical methods integration, through the model self-learning, solve the sparsity of the judgment matrix, and evaluation index of comprehensive and objective of problem. By introducing the machine learning algorithm, using Matlab to calculate, the important features of the data hidden behind the data mining, the establishment of a good robustness, high accuracy of the identification of the model. © 2017 IEEE.

For the hot spots problem caused by the number of replica could not satisfy the soaring request from users, we present a Cloud Computing storage resource replica dynamic scheduling scheme based on HDFS. There are two sub algorithms which is the number of replica dynamic adjustment algorithm and replica placement algorithm. This scheme could improve system stability and file access through put. The experiment result shows this optimized scheme lower the access delay obviously than the original scheme with some cost of storage resource and network workload. For the problem of metadata management, this paper introduced a distributed metadata management scheme. This scheme distributed metadata into several name node according to their ability, and provides an efficient inquiry algorithm for metadata to improve system availability and reliability. The experiment result shows the multi-name nodes system with this metadata management scheme could improve the performance than the original system facing the huge metadata operation requests. © (2014) Trans Tech Publications, Switzerland.

We have built a physical model about macromolecule's chain conformation by applying the methods of physics, and then we have mainly simulated macromolecule chain's conformation. We also have studied the single chain system conformation's size which represented by mean-square end to end distance R2 and mean-square radius of gyration R2, shape and the variation of energy which acted between different chain lengths. The results shows that the average energy Ec and the size which represented by mean-square end to end distance R2 and mean-square radius of gyration R2 are proportional to the variation of chain's length. When the chain lengthens, the distribution of chain conformation in a small size area will be expanded and increased. When the chain length reaches from 10 to 16, chain conformations are mostly distributed the area with high energy and small size. © 2011 IEEE.

We have acquired the approximate method about how to get macromolecule's relaxation spectrum by means of experiment data. Depending on steady state stress relaxation experiment or dynamic shear experiment, we have gotten steady state relaxation modulus function G(t) or dynamic state modulus function G′(ω) and G″(ω). And then we have calculated all the approximate solutions of relaxation spectrum H(λ). Depending on the melt storage modulus G′(ω) data and power cost modulus G″(ω) data which from dynamic linear small swing shear oscillating experiment, we have calculated discrete relaxation spectrum in accordance with the approximate formulas which proposed by Schwarzl and staverman. At last, we also have discussed the affection of discrete relaxation spectrum which caused by some parameters and temperature. © 2011 IEEE.

On the basis of molecule chain model of macromolecule material, we have studied the affection of rheological property which caused by macromolecule material chain structure, macromolecule material average weight and macromolecule material viscosity. We also have studied the affection which caused by macromolecule material molecular weight. What we have studied is very important to study macromolecule material rheological property and science of macromolecule material. © 2011 IEEE.

On the basis of equant roll calender, we have designed non-equant isometric roll calender which applied in macromolecule material. This kind of calender can be realized by decreasing the diameter of one or two rolls properly. And a pair of non-equant roll calender can be constructed by means of one big roll and one small roll. During the process of design, we have built the corresponding mathematical model. And we have calculated the non-equant roll calender's key problems in accordance with this mathematical model. By comparing with traditional calender, non-equant roll calender has such advantages as high precision, low pressure load, low power consumption and rapid speed. © 2011 IEEE.

In this paper, we have mainly studied the terylene's anti-static effect which has been processed by means of external use negative ion anstatic agent, external use positive ion anstatic agent, external use amphoteric anstatic agent, external use nonionic anstatic agent and chemical fiber anstatic agent. We also have compared with the anti-static effects in accordance with anstatic agents with different densities. At the same time, we have analyzed some anstatic agents' water-tolerant and washing experiments. At last, we have analyzed several kinds of anstatic agents' effects. We have concluded that macromolecular compound has excellent anti-static ability and water-tolerant ability. © 2011 IEEE.

Melt Fracture (MF) is a kind of unstable fluxion of extruding moulding. We have analyzed the process of MF and introduced macromolecule material solid solution's viscosity and unstable fluxion which can damage the stable fluxion. This is the main reason of MF which caused by irregular moulding and slippage. In this paper, we also have studied the mechanism of melt fracture, what we have studied is import to eliminate melt fracture. © 2011 IEEE.
