In this paper, based on the research and analysis of the existing typical e-commerce logistics models, namely, enterprise itself, third party logistics, logistics alliance and other models, through the analysis of the logistics decision method, a logistics decision method based on business logistics cost is proposed, which has a certain reference for the conduct of e-commerce enterprises in the logistics...
In order to solve the problem of rigidity in IT architecture and the existence of heterogeneous information islands within most enterprises, a novel service-oriented IT architecture SOA (service-oriented architecture)emerges. The realization of SOA is embodied in the accomplishments of various IT applicable functions in the form of service encapsulation and the interconnection and interoperation of...
We present the adaptive simulations of Amrita Learning, a web-based, interactive eLearning program that aims to create a realistic mathematics and science laboratory environment for school students to study equipments, perform simulation experiments interactively, measure or analyze results, and understand their application, It teaches abstract concepts, such as flow of electrons and magnetic fields,...
Hyphantria cunea is one of the harmful international plant quarantine pests. In order to monitor and control the increasingly serious situation, based on the materials and data collected by “the 221 project” in Beijing in recent three years, this paper studies the spatial decision-making system of hyphantria prevention and control simulation, by combining WebGIS, JSP and Ajax technology. We design...
In order to carries on the plan and the control to aircraft level flight, the attitude and the route has been analyzed. First obtain that the factors control the level attitude are the roll angle and the yaw angle, and infers the computation algorithm of attitude; then obtain that the factors control the level route are the route position and the radius of turn, and infers the algorithm of flight...
Due to the transmission speed limitation of MIL-STD-1553B, no support for large data transmission especially, many departments have tried to improve the MIL-STD-1553B protocol. On this background, it is a necessity to develop a flexible and scalable simulation system to meet the demands of validating the improved protocol. Based on multi-thread technique, this paper designs an integrated MIL-STD-1553B...
