Education experienced by foreign-born faculty whose native countries have undergone major socio-economical changes

Three professors of education reflected on education in their countries of origin, and compare their education with learning, teaching and the education in the United States. The three countries represented are China prior to the political and economical reforms starting from 1979, Iran prior to the Islamic Republic of 1979, and the Russian Federation of the Former Soviet Union prior to the fall of the Soviet Union in 1991. Certain aspects of education such as the curriculum, pedagogy, length of schooling, methods of teaching, the textbooks, and priorities and goals of schooling in each country are discussed. This article is a comparison of the educational system of each country with the American educational system as well as among the three countries. The article concludes with each author offering some ideas on how the American educational system might benefit from the experience of the other countries.

Try to say The Differences Between American and British English

Talking about American and British English, we know the variation is considerable, but there are no accurate estimates for the number of points of contrast. Because recent decades have seen a major increase in the amount of influence the two models have had on each other, especially American on British. For example, the influence of films and television on each other. Another reason is, the     

优化网格服务请求的QoS 性能

Workload of each service class varies dynamically in the grid environment,making the static service pool size allocation scheme unable to guarantee the QoS requirement of each service class.In this paper,we link the issue of dynamical service pool size allocation scheme with QoS requirement under the varying workload,and formulate the QoS performance of service requests in the grid environment by queue theory.Combined Lagrangian optimization with a bisearch approach,the problem of optimally allocating service pool size scheme is resolved.Simulation results Show efficiency of the optimal service pool size allocation scheme.     

Hierarchical topic modeling with nested hierarchical Dirichlet process

This paper deals with the statistical modeling of latent topic hierarchies in text corpora. The height of the topic tree is assumed as fixed, while the number of topics on each level as unknown a priori and to be inferred from data. Taking a nonparametric Bayesian approach to this problem, we propose a new probabilistic generative model based on the nested hierarchical Dirichlet process （nHDP） and present a Markov chain Monte Carlo sampling algorithm for the inference of the topic tree structure as well as the word distribution of each topic and topic distribution of each document. Our theoretical analysis and experiment results show that this model can produce a more compact hierarchical topic structure and captures more fine-grained topic relationships compared to the hierarchical latent Dirichlet allocation model.

Under high loads, a multimedia cluster server can serve many hundreds of connections concurrently, where a load balancer distributes the incoming connection request to each node according to a preset algorithm. Among existing scheduling algorithms, round-Robin and least-connection do not take into account the difference of service capability of each node and improved algorithms such as weighted round-Robin and weighted least-connection. They also do not consider the fact that the ratio of number of TCP connections     

Modern Sound-light Electrochemical Technology and Public Art

The modern science and technology advances with each passing day,while the art also develops to the situation of letting a hundred flowers blossom.The progress of science and technology will eventually be turned into the presentation of art,and the inspiration of art will direct the development of science and technology as well.The both sides complement each other.The application of the modern science and technology in public art is valueable and has its own special artistic forms.The real value of the application is to use the modern methods to present the dynamic and developed world in modern artists’ hearts.

Architecture Singularity Analysis of 4-U■S/U■U 5-DOF Parallel Mechanism

Architecture singularity of a parallel mechanism with five degrees of freedom (DOF) is analyzed. Such mechanism consists of a movable platform connected to the base by five active limbs. Four of them are identical 6-DOF limbs and the last one has the same DOF as the specified DOF of the movable platform. Based on the kinematics analysis, two categories of architecture singularities for such mechanism are proposed. Then the sufficient condition for each singularity is researched. Results show that the mechanism is singular when it employs each category of the proposed architecture, provided that it satisfies the corresponding sufficient condition. It can be concluded that the proposed two categories of architecture singularities should be avoided with the following dimensional synthesis of such mechanism.     

A Decision Model for Selecting Participants in Supply Chain

In order to satisfy the rapid changing requirements of customers,enterprises most cooperate with each other to form supply chain.The first and the most important stage in the forming of supply chain is the selection of participants.The article proposes a two-staged decision model to select partners.The first stage is the inter company comparison in each business process to select highefficiency candidate based on inside variables.The next stage is to analyse the combination of different candidates in order to select the most perfect partners according to a goal-programming model.
