Abstract: MultiSim is a famous electronic designed automation software, which is widely used in circuit teaching, circuit design and SPICE simulation. In this paper, the MultiSim software is introduced into electronic circuit teaching, the three-section teaching pattern and six-step teaching process are proposed, meanwhile, the teaching design examples of three-level amplification circuit and its frequency characteristic analysis are also demonstrated. The research results show the advantages of MultiSim virtual simulation software are to build a learning platform to explore, resolve the difficulty of teaching, and promote students thinking. MultiSim virtual simulation software is a carrier of learning for students, it is the source of the question, it is an effective tool for improving students learning enthusiasm and initiative.

Abstract: To solve the Dual Resource Constrained Job Shop Dynamic Scheduling Problem with heterogeneous workers (DRCJDSP-HW),a three-tier dynamic scheduling system including dynamic disturbance analysis, dynamic disturbance evaluation and dynamic scheduling method was constructed based on the idea of scheduling with local time window. To minimize the revision of old scheduling scheme in DRCJDSP-HW, a hybrid dynamic scheduling algorithm was proposed based on the chromosome reduction mechanism and the scheduling optimization of local job in stages. The outstanding application effect of the dynamic scheduling system and the hybrid dynamic scheduling algorithm were validated reducing the influence of dynamic disturbances effectively by simulation experiment at last.

Abstract: At present the awareness model of network security situation can only analysis the network security situation of past or current time. The lack of research on this field will affect the security of network. A method based on Kalman algorithm is proposed in this paper, which can forecast the network security situation by using the current and past security situation values. The simulation results show that the proposed algorithm can not only reflect the overall trend of network security situation but also forecast the trend of value effectively. Compared with the traditional GM(1,1), the method has a more predictive value; Compared with RBF algorithm, the method is more applicable to the real network environment.

Abstract: Flash has become the major technique in developing network courseware. This paper analyzes the advantages of flash network courseware: compactable size, outstanding animation effect, effective interaction and network spread convenience. In addition, it introduces the design process and main content for developing a flash courseware. Finally, it analyzes the major methods for adopting Flash in developing network courseware.

Abstract: Equipment manufacturing industry belongs to "high technology, high value-added" industry, providing equipment for other industries and protecting Chinas industry security. The paper study how to take advantage of the industry clusters to support the development of equipment manufacturing industry. Firstly, the paper analysed the present stage of China's manufacturing industry clusters,and Concluded that Chinas primary industry cluster stage has been completed. In this case, the model of Chinas industry cluster should transfer from "low technology, low value-added, low wage" to "high technology, high value-added, high wage". Secondly, the paper analyzed the internal industries interaction in cluster and the interaction between the cluster and the external area, and how they support the development of the equipment manufacturing industry. The paper pointed out: Industrial cluster has many benign interaction mechanisms, and the upstream and downstream industries inside the clusters can form a mutual promoting and spillover effect, and this effect will influenced the development of equipment manufacturing industry. Meanwhile, the interaction of cluster and external educational institutions, research institutes will support the development of the equipment manufacturing industry.

Abstract: The express delivery services (EDS) industry is an important field for Internet of Things (IOT) application. Based on reviews of current research on IOT and current application of IOT, this paper addresses major issues in the application of IOT in EDS industry, analyzes opportunities and threats in the application of IOT in EDS industry, and gives suggestions on how to apply IOT technology in EDS industry.

Abstract: The law of equipments or products life is the calculation fundament of reliability indexes in power plant. Aim to how to determine the most fitted life distribution type, the linear regression and correlation coefficient had been employed in this paper. The linearization of common distribution like as: exponential distribution, normal distribution and logarithmic normal distribution, is complied with the principle of linear regression. After the comparison of correlation coefficient, the most fitted distribution type is quickly found out. The result also shows that the inferred distribution type is in accord with the facts. We may draw the conclusion from this research that the optimized linear regression and correlation coefficient is effective and valid for the inference of life data distribution type.

Abstract: Multi-core processor parallels two or more computing core in a single processor to enhance computational capability. Plenty of former researches are focused on CMP (Chip multi-processor), the most typical structure of multi-core processor. Thus deign of cache coherence, in particular, is one of the primary problems beyond other researches about CMP. In this paper, cache coherence protocol of CMP is fully presented, along with its advantages and disadvantages. Finally, some edging issues of cache coherence protocols are addressed in this paper.

Abstract: One of the controversial issues in manufacturing systems is bottleneck. Managers and engineers are trying to find methods to eliminate the bottlenecks and waiting times in the production line. More over the manufacturing companies are striving to sustain their competiveness by decreasing the bottlenecks, total cost and increasing the productivity. The objective of this study is applying the computer simulation to analysis the production line bottlenecks. To achieve this goal a color manufacturing line was selected as a case study and the basic application of arena 13.9 software. Finally the some modifications in the simulation model are proposed to improve the production line as well as to decrease the bottleneck.

Abstract: Propose the method of acquisition boards interface via EPP protocol and CPLD. Give a detailed technical solution. Communications speed can reach 1000kB/s. At the same time fully meet the requirement of vibration signal processing high-speed synchronous.
