Network-in-the-loop is the direction that the military training simulation is advancing forward. Dynamic networking modeling is the key issue for constructing the network-in-the-loop training simulation. For this purpose, the fundamental architecture for the network-in-the-loop training simulation was analyzed and presented. Several features of dynamic networking modeling were researched. Based on a general view of the network, a set of networking models suitable for the network-in-the-loop training simulation were constructed, including the aggregated vehicle node model and latent link model. Now, these models are working well in a certain training simulation.

The aim of this paper is to introduce the application of an S-shaped transition curve in designing and generating a spur gear. In engineering field, the spur gear usually designed by using an involute curve where this curve needs to use a tracing point method to obtain a curve while an S-shaped curve can obtain a curve directly. The comparative study between an S-shaped method and direct method in computer aided design (CAD) tool also covered.

This paper presented architecture approach to remote monitor and control for providing protection and self-restoration against fault in the distribution region of fiber-to-the-home passive optical network (FTTH-PON). The devices consist of optical switches and a microcontroller to handle the optical switch routing. It is employed at the customer end, just before the optical network units (ONUs) to ensure the data flow continuously due to breakdown occur in the network and instantly repair operation.

In order to describe traffic operation characteristics of bi-directional pedestrian flow in urban pedestrian walkways and work for walking safe, authors proposed an improved cellular automaton bi-directional pedestrian flow model. This model takes into account many basic pedestrian behaviors, forward move, side stepping, position exchange, lateral-move and step back, and, using MOORE Neighborhood method, provides rules of pedestrian movement combining with the characteristics of walking process, for instance, intelligent, flexible and complicated. With computer simulation, authors studied the influence of position exchange and lateral-move on the model, the parameters of bi-directional pedestrian flow such as velocity and volume were discussed also. The results demonstrated that position exchange and lateral-move make the pedestrian behavior more comprehensive;the model could be better applied to simulate the high-density bi-directional pedestrian flow and provided reasonable traffic operation parameters of bi-directional pedestrian flow.

Professional development of teachers plays a significant role for the success of educational reforms and for student achievement. Programs for developing teachers' skills to integrate digital media in the classroom have received increased attention, due to the role of technology in today's world. Recent research and field experiences have identified elements which contribute to the effectiveness of such programs, among them opportunities for sustained, collaborative and self-directed learning. This paper explores how an online platform of a large scale blended program for professional development, Intel (R) Teach - Advanced Online, supports the implementation of such opportunities in practice and incorporates them in the structure of the program. The positive outcomes from the program as evidenced by its evaluation indicate that professional development based on the design principles identified as effective by recent research is a viable solution for addressing the limitations of traditional teacher training for technology integration.

The controlled distribution of a fluid to the entrance surface of a process, or into the volume of equipment, is an important issue for various aspects of process performance. The flow field in the inlet double-bend distributor and single-bend distributor were obtained through the numerical solution of the governing partial differential equations including the conservation equations of mass and momentum. The experimental studied prove good agreement between the model simulation and experiment data. The results show that double-bend distributor has more advantage than single-bend one; the behavior of flow is very dependent on flow pattern upstream of the distributor.

As the constrained conditions, the urban system of the host cities influence the Post-Games development of the Olympics' venues significantly. Based on the interactive mechanism between the urban system and the Olympics' venue projects, as well as the demand theory, this paper explores the main factors of the urban system are per capita GDP, population, ratio of the service industries of the urban system, which influence post-Games development of the Olympics' venues. Meanwhile, with the relevant statistic materials of the recent Games host cities in the Games year, applies two methods of ward cluster analysis and k-means cluster analysis to verify the validity of the three factors which influence post-Games development of the Olympics' venues. The Olympic Events hosted cities in China-Beijing, Hongkong, Qingdao and other cities are clustered with the recent Games host cities, and the differences are discussed. So conclusions are given that support of urban system of hosting the 2008 Olympic Games in China for the post-Games development of Olympics' venues is no strong, and the relevant strategies are introduced, such as attracting external consumption, improving the relative industries of the urban system, etc.
