University human resources loss has become one of the most important problems in education developing areas. According to human nature hypothesis, the reasons of university human resources loss are analyzed from the angle of economic man, social man, self-actualizing man and complex man, these conclusions propose theoretical basis for solving university human resources loss.
As one of the optimum design of enclosure structures for deep excavation, the double-row pile has advantages of large lateral stiffness, no support and small footprint. But more studies should be done on how it works practically. the paper summarizes the currently used model, analyses and compares of their characteristics. Using a typical example, verifies the advantages and disadvantages of flexible...
Investigation theme of this paper is "special school teachers in the application of information technology", a series of comprehensive practical investigation is given for special education school teachers of different regions, type, forms. We hope understand the application situation of information technology in special education teaching by this survey, and propose some measures to improve,...
In order to study the bearing capacity of a joint in composite structure of a railway station, A 1∶4 scale specimen subjected to the monotonic and hysteretic load was investigated through laboratory test. Belonging to the overloaded floor system which spans about 36m×28m, the joint connects the concrete-filled steel tube column with steel reinforced concrete beam, size of which exceeds more than 1...
When D-STATCOM is used in load comprehensive compensation, the preciseness of detecting the compensation current required by the system is very important for compensation effects. There are many detection methods at present. This paper describes and analyzes the principle of the traditional id-iq detection method, and presents and simulates a improved id-iq detection method to eliminate the errors...
A novel dual-frequency circularly polarized microstrip antenna is designed in this paper. The antenna has a structure of two microstrip board layers, and employs two circular patches which have different radius can achieve the resonance of dual-frequency, which opens a slot in the upper radiation patch in order to reduce the patch size. The antenna can work at GPS L1 band (1.575GHz) and Beidous band...
Based on control equations in fluid dynamics, the main thought of oil spray process for full-automatic cold header is proposed according to the idea of green manufacturing. The CFD software is applied to simulate the multiphase oil mist flow in control box of the oil spray process with numerical method. The simulation results are discussed including temperature, pressure, velocity and multiphase fluid...
In view of genetic superiority in data mining algorithms, this paper combines the genetic algorithm and K-means algorithm and presents a genetic algorithm based k-means clustering algorithm and the algorithm to improve genetic clustering algorithm clustering using variable length actual real number of cluster center, and design a new crossover and mutation operators and the introduction of is widely...
A fresh air system with solar collectors and Latent Heat Thermal Storage (LHTS) tank filled with Phase Change Material was firstly introduced in this paper. For the mathematical model of the fresh air system is difficult to accurately establish, the adaptive neuro-fuzzy inference controller was proposed to realize the parameter identifications of the system applying for the back-propagation algorithm...
This paper studies the relationship between cooperation patterns and resources of university in international science and technology cooperation and exchanges based on correspondence analysis method, makes assessment and judgment about pattern selection of international science and technology cooperation between universities in terms of human resources, technology level, financial resources, analyzes...
In multi-cluster sensor network, the inter-cluster interference is a factor to bring packet loss and energy cost. In this paper, a slot pre-allocation algorism to deal with the inter-cluster interference in TDMA based sensor network is proposed. The algorism is totally based on TDMA MAC, without using frequency enlarged methods such as CDMA and FDMA, can be easily implemented and not demands additional...
Teachers evaluation is the important part of teaching management works in universities, which is helpful for supervising and responding teaching situation and teaching effectiveness. This paper introduces the design idea and implementation methods of the teaching evaluation management system based on Web. The teaching evaluation management system is designed on the actual teaching evaluation management...
In order to compress calculation, the background estimation algorithm for the infrared target detection was proposed. Firstly, a Least Square Matrix is proposed and an image background is estimated. Then the target is detected by self-adaptive threshold detection in different images. It is shown by nonlinear function regression experiment and sequence infrared image detection experiment whose methods...
The rational and efficient allocation of human resources is a prerequisite to improve overall efficiency of the organization. This article analysed and evaluated the related elements of organization, and then it proposed a two-way choice model of optimal allocation of human resources form the maneuverability. We used the genetic algorithm to solve the model and designed detailed process of the algorithm...
Uses the small shake table model experiment to confirm the mechanism of the liquefy sandy soil of has not reinforced and be marker reinforcement by the gravel pile, the key contrastive.
Trust is a key constraining factor in the development of electronic commerce. The parties must establish a certain trust model between each other before the beginning of transaction. This paper analyses the advantages and deficiencies of existing models, and presents a trust model for E-commerce based on Bayesian network. The model is based on Bayesian network and conditional probability formula,...
Citizen political participation in future will inevitably show a lot of revolutionary features of digit and network. The rise of e-participation is closely related to the rapid development of social economy and network technology. The political background of e-participation is mainly composed of the crisis of representative democracy and the trend of direct democracy. Moreover, the new ideas of service-oriented...
We can find potential relationship behind the data by data mining for e-commerce, so adjust dynamically web page structure, improve service, and meet better consumer demand. This paper discusses the data resources used by data mining in e-commerce and their characteristics, gives the basic process of data mining, analysing e-commerce data mining techniques used, at last points out the current problems...
This paper gives an improved alamouti 2*2 strategy in dense wireless sensor networks after analyse the model of communication between the transmitting cluster and receiving cluster. Simulation show the results of energy consumption among worst-channel, random-channel and optimal-channel. Some rules are given in the process of the simulation analyse.
In this paper we study the problem of collaboration in RF-Sensor networks, comprised of a large number of very small and low cost nodes, capable of sensing, communicating and computing. The Multi-phases Collaboration of such nodes may lead to the accomplishment of large sensing tasks, having useful applications in practice. First, we research two collaboration methods, one is no collaboration and...
