This paper presents the design and implementation on a new architecture of broadband network system which suitable for asymmetric digital subscriber line (ADSL) application. The main design skill is based on the cell-based digital IC design process, and is implemented in 0.18 µm 1P6M CMOS process. The main function of this chip is to build a bridge between Ethernet and ATM which is used to substitute for RISC processor, leading to enhance the broadband network switching ability and stability. Furthermore, the clock management system is adopted to manage the packages. By this technique, a small size and low cost chip will be obtained.

Trojan is a Trojan horse hiding technology, one of the key technologies, directly determine the viability of Trojan horses. This paper describes the current commonly used Trojan horse hiding technology, the traditional implementation method Trojan hidden lack of independence, according to concerted hidden thought, given the four threading model under Windows systems and their specific implementation method to explain the problems encountered in the implementation process and solution approach. In response to the four further threading model is just to restore the initial state of the shortcomings of the passive given extension model. Experiments show that the four threads together more independent thought hidden Trojan horse has a better prospect.

Information sharing is a new service mode originated from academic libraries in the United States in the 1990s. Having analyzed the causes of low level of technological innovation in universities from information sharing perspective, the paper suggests constructing a information sharing platform of technological innovation achievements on the basis of service science and knowledge sharing. Moreover, the author approaches a subject on building a new information sharing mode, which is market-oriented, research-based, product-linked and innovation-aimed. This mode is also expected to provide special knowledge products and services.

The selection of project management (PM) software is a complex issue and has significant impacts to the efficiency of the automobile research & development (R&D) process. Given two alternatives based on critical path method (CPM) and critical chain project management (CCPM) respectively, decision-makers usually cause confusion. This paper analyzed the characteristic of automobile R&D project and developed an evaluation model based on the fuzzy analytic hierarchy process (FAHP) and fuzzy multiple criteria decision making (FMCDM) methods, which can help the managers in automobile industry to select more appropriate software in the course of product R&D. In particular, the FAHP method is used to obtain the weights of evaluation criteria, and the FMCDM method is used to determine the final rank of the software. The uncertainty and vagueness in evaluation procedure were presented as the fuzzy triangular numbers. The proposed method is applied to the case study of evaluating the performance of PM software based on CPM and CCPM respectively for a car manufacturer. The result of evaluation not only assisted managers in choosing suitable software but also outline the trend in development of CCPM software.

A technology-mediated learning space is not a technology-shielded island. Technologies may promise to facilitate human learning, but should never detach learning from social context. Computer-mediated communication (CMC) has created new opportunities for synchronous and asynchronous collaborative learning among geographically dispersed individuals. This study especially explores four social considerations in Computer-supported collaborative learning (CSCL), including roles, trust, nimbus, and interpersonal familiarity.

Teaching method is the means and ways to implement the task of teaching. The purpose of this study is to select the appropriate teaching methods for a newly developed school-based curriculum Introduction to Zhejiang Business Culture. A validated and reliable self-administered questionnaire developed by the investigators was used in the study. 70 students from Zhejiang Economic & Trade Polytechnic were chosen as samples randomly. It was emphasized that participation was voluntary, and respondent confidentiality was assured. Results shows majority of students believe that visits to businesses, real circumstance training, and group discussion may work well. Questionnaire results also indicated that the examination form should be flexible. In stead of the solely writing examination, the performance of students in the discussions and training should be given full consideration and appropriate rating. Flexible teaching methods can stimulate student's passion for learning, develop their independent problem-solving skills, and markedly increase the student's satisfaction to the curriculum.

Being different from general continual-data stream BER tester, the receiver of burst-mode BER tester is required to extract clock and recover data accurately from the incoming datasteam characterized by phase variation within a dozen bits time before error bits detection is conducted, moreover, while error bits detecting, the receiver should filter the preamble and delimiter and execute error bits statistic only for Payload. In this paper a design method for Burst-mode BER Tester Based on FPGA is put forward. First of all, the whole structure of this design is introduced, and then the logic function modules implemented in the FPGA and system control program are presented in detail separately. The experimental results of applying this test equipment to 1.25G burst-mode optical receiver in GPON system illustrate that it has good performance and practical value.
