Abstract: With the rapid growth of the Internet, the interest for connecting devices such as frequency converters into Internet has increased. Web browser is used by remote operator to control and monitor frequency converters via Internet and this application will be widely utilized. This article makes a study of web-based monitoring for frequency converters with USS interface. It is based on TCP/IP stack and the real time operating systemμC/OS-II. Then this paper presents a detailed analysis of the Web server, and the interactive method of the browser and the Web server. In the design of the server, it emphasizes the USS protocol telegram processing method. The architecture of embedded monitoring system, hardware and software implementation are also described in this article.

Abstract: Web search engine based on DNS, the standard proposed solution of IETF for public web search system, is introduced in this paper. Now no web search engine can cover more than 60 percent of all the pages on Internet. The update interval of most pages database is almost one month. This condition hasn't changed for many years. Converge and recency problems have become the bottleneck problem of current web search engine. To solve these problems, a new system, search engine based on DNS is proposed in this paper. This system adopts the hierarchical distributed architecture like DNS, which is different from any current commercial search engine. In theory, this system can cover all the web pages on Internet. Its update interval could even be one day. The original idea, detailed content and implementation of this system all are introduced in this paper.

Abstract: In recent years, we have been studied about medical data analysis, especially for the rehabilitation data provided by a hospital, and extracted the recovery tendency of patients from their Functional Independence Measure (FIM) data. This time, we adopt the nonnegative Tucker decomposition (NTD) method, which is known as an extension of the nonnegative matrix factorization (NMF) to higher-dimensional data, to the medical data built up by piling each FIM data at some time points for several patients. Since the all elements of the tensor and matrices obtained by the NTD are nonnegative, it is expected that this method makes the interpretation of the characteristic vectors which are obtained from the resulting matrices easy and intelligible in comparison with our former approach, which used the multi-dimensional principal component analysis (MPCA). The experimental results show the effectiveness of proposed approach.

Abstract: The algorithm of hologram compression using BP neural network in wavelet domain is proposed. Firstly, computer-generated hologram pretreatment is carried out by wavelet transform. And then the inner product of wavelet and holograms are weighted and used to implement the feature extraction of hologram. Finally, the extracted feature vectors are substituted into neural network so as to implement the function approximation, classification and hologram compression. The experimental results clearly show the feasibility and effectiveness of the method. The compression rate can reach 0.803%and still gets a clear reconstructed image. And the algorithm has the advantages of simple structure and fast calculation speed.

Abstract: The experiment circuit is divided into two parts: fixed and non-fixed in a synthetical teaching experiment for SCM.The fixed part is made ​​of printed circuit board in its auxiliary device, the non-fixed part is lapped on the bread board by the experimenters .Above contents include:(1) system storage structure is non fixed, which using the jumper switch K1, the system structure may become the Princeton structure, or Harvard architecture or no RAM structure;(2) system storage capacity is non fixed, which using the jumper switch K1,K2, the chip EPROM or RAM is arbitrarily selected by experiment system according to the needs. Experiences show: this auxiliary device improves the flexibility and versatility,saves time, strengthens the experimenter’s operational ability and improves the success rate for the SCM experiment.

Abstract: With the explosive growth of the World Wide Web information, we need the appropriate retrieval tools, especially the retrieval of the professional information, we need a embody of search engines with the professional vocabulary features. Based on the research of search engine's core technology, this paper presents a design scheme which is the botanical garden plant information search engine based on Internet data, we descript of its design.

Abstract: fingerprint image preprocessing and is one of the branch of image processing and pattern recognition, after several years of development the increasing maturity of the technology. Due to the uniqueness and invariability of fingerprints, and the feasibility and practicability of the fingerprint identification technology, fingerprint identification has become the most popular, the most convenient, one of the most reliable personal identity authentication technology. Although on this technology has a variety of molding products, but because many of the core technology by commercial interests and confidentiality need without open, as well as the development of the society put forward higher requirements on the performance of the system, so in this field of research, still has important theoretical significance and practical value.

Abstract: In order to solve dispersed resources of enterprise and diversity of manufacture, put forward the methods to realize manufacturing information using cloud technology. The key technologies of cloud computing and cloud manufacturing are discussed for small or middle manufacturing enterprise and studying technology characteristic, application pattern and realizing method for cloud manufacturing service platform. Fault diagnosis, performance evaluation and maintenance are shown on cloud manufacturing platform so that obtain data of equipment's state on line. Thus, improve equipment utilization and reduce shutting down time and maintenance cost.

Abstract: In computer-aided design meteoric rise in the field of architectural design , computers have become an important tool for architects work. The use of computers has changed a lot of work methods. Updated key architectural design methods, using new thinking tools by updating to assist architectural design ideas that can help us find new ways to architectural creation. We know that there is a convenient three-dimensional computer modeling, easy to modify and intuitive physical display. The concept of the future whether to play a vital role in the concept of the method, and eventually will change and affect the building design and construction. By using computer-aided design and design examples to make computer-aided design method building construction design process , the use of further explanation.

Abstract: With the increasing data amount of 3D models of view-dependent progressive mesh in recent years, it is more and more difficult for the efficiency of the traditional serial vertex processing algorithm to meet the current demand for the rendering time for models. Therefore, this paper proposes a parallel vertex processing framework based on the half-edge structure view-dependent progressive mesh, enabling users to obtain not only the dynamics of three-dimensional progressive mesh models but also the improving rendering efficiency.
