Abstract: This paper discusses the definition, characteristics of China English and its inevitability of being accepted as a new member of the world Englishes, elaborating the pedagogical implication of the recognition of China English in China’s EFL.

Abstract: Based on the synthesis and analysis of recursive receivers, new algorithms are proposed to achieve satisfactory performance with moderate computational complexity. During the analysis, some interesting properties shared by the proposed procedures are described. Finally, the performance assessment shows that new schemes are superior to the linear detector and ordinary grouping algorithm, and achieve a bit-error rate close to that of the optimum receiver.

Abstract: Forest ecosystems provide a lot of service functions which are not only sustainable conditions for life, but also the material foundation and guarantee for human survival and socio-economic development. Therefore, these years more and more attention has been paid to forest health and health assessment has become extraordinarily important. This study is primarily based on the evaluation criteria prescribed by Continuous Forest Inventory Technique, combining with site, geography, climate conditions and so on in Liangshui nature reserve to define the evaluating indicators. In this thesis, windthrow hazarel is divided into four grades: zero, mild, moderate and severe. The data of forest resource inventory in Liangshui nature reserve in 2009 is used to calculate the accumulation of different forest compartment and species of wind fallen trees. And based on ARCGIS, windthrow hazarel geodatabase, disaster distribution, volume distribution of wind fallen trees of Liangshui nature reserve are built and mapped. Then with the combination of aspect, slope and stand density distribution, this thesis is to analyze the factors which influence the disaster grade and distribution, to propose target-oriented prevention measures and treatment strategies. The results demonstrate that in Liangshui nature reserve, forest compartments in mild disaster are the most with the total number of 21, those in moderate disaster are 4, in zero degree disaster are 4 and in severe are 2. And the area of forest compartments whose main variety of wind fallen tree is pinus koraiensis takes up over 45% of the total forest zone, the area of forest compartments whose main varieties are fir and spruce takes up approximately 40%, and the areas of forest compartments whose main varieties respectively are poplar and basswood takes up about 10% and 5%.

Abstract: For the purpose of discussing the potentiality of composite materials in information protecting, the microwave transmitting properties of epoxy-based carbonyl iron composite material was systematically analyzed in this report. The effective medium approximation (EMA) model was used to calculate the electro-magnetic parameters of the material, while the transmission line model was used to calculate the absorption ability of the composite material. Good agreement between calculation and experiments was obtained, which means the rationality of the describing method in this paper.

Abstract: As a kind of information protecting technology, material compositing becomes more and more important. The microwave properties of composite materials depend on many aspects, but stuffing is the most critical. The effect of conductive stuffing, magnetic stuffing, and the mixed stuffing are compared and analyzed in this report. It is found that conductive stuffing has the lowest absorbing behavior, while magnetic stuffing is best choice for composite. The mixing of conductive stuffing and magnetic stuffing does not result in better absorbers.

Abstract: ERP-Enterprise Resource Planning is an advanced management tool, which can provide effective service for enterprise purchasing manufacturing, marketing and goods circulation etc. The fast changes of market and drastic competition between enterprises request ERP system can support enterprise Business Process Reengineering and reconstructed business process. This paper analyzes the disadvantages of traditional ERP system, the request of Business Process Reengineering, then brings forward a workflow based method for analyzing, building, developing and executing ERP system. The research of this thesis is built on J2EE application platform, the application model, component implementing and work mechanism of workflow in ERP system.

Abstract: This document explains and demonstrates the basics of how email is work on the Internet. By analyzing the working process of e-mail, it try and describe some tips that can help reduce the number of emails you send out that get blocked by spam filters.

Abstract: The evaluation system of constitution in Traditional Chinese Medicine(TCM) is designed by relational-like data base Access, based on interface, function buttons, and menu, designed by VBA language. The system links to office word in order to achieve the automation of the issuance of constitution assessment and healthcare programmes. The design includes four parts, they are, overall design, interface design, evaluation test design and constitution report design. This system shows some advantages, such as simple operation, good stability, low requirements of equipment configuration, vividly visual interface. By analysing information on examinees' lives, their constitutions can accurately be identified, and the reports of the constitutions can be issued. Besides, relative healthcare suggestions are also attached. The convenience of the process is suitable for outpatient services, physical examination centers, and family health, and among which the system can be popularized.

Abstract: Due to the existing of the semantic gap, images with the same or similar low level features are possibly different on semantic level. How to find the underlying relationship between the high-level semantic and low level features is one of the difficult problems for image annotation. In this paper, a new image annotation method based on graph spectral clustering with the consistency of semantics is proposed with detailed analysis on the advantages and disadvantages of the existed image annotation methods. The proposed method firstly cluster image into several semantic classes by semantic similarity measurement in the semantic subspace. Within each semantic class, images are re-clustered with visual features of region Then, the joint probability distribution of blobs and words was modeled by using Multiple-Bernoulli Relevance Model. We can annotate a unannotated image by using the joint distribution. Experimental results show the the effectiveness of the proposed approach in terms of quality of the image annotation. the consistency of high-level semantics and low level features is efficiently achieved.

Abstract: The rapid development of Graphic Processor Units (GPU) in recent years in terms of performance and programmability has attracted the attention of those seeking to leverage alternative architectures for better performance than that which commodity CPU can provide. This paper presents a new algorithm for cutting display of computed tomography volume data on the GPU. We first introduce the programming model of the GPU and outline the implementation of techniques for oblique plane cutting display of volume data on both the CPU and GPU. We compare the approaches and present performance results for both the CPU and GPU. The results show that cutting display image generated by GPU algorithm is clear, frame rate on GPU is 2-9 times than that on CPU.
