Among various industries, there are so many kinds of product structure and also many ways of manufacture, it is hard to give a universal standard for BOM, so that it is important to give a deep study into this field. Based on the research into the structure as well as the production way of BOM, the study puts forward one coding principle, which combines the product structure with serial number of...
Complex network theory is put forward in following research to analyze the statistical parameters of network business statically in E-commerce area. Empirical Study is based on the data provided by an online shopping website and statistical parameters such as enterprise act degree and clustering coefficient is studied accordingly. Thus we found that E-commerce displays the power law and clustering...
Optical current/magnetic field sensor based on creation of the Faraday rotation effect in cerium-substituted yttrium iron garnet single crystal has been presented. Here we focus our studies on improving the magneto-optical properties and sensitivity constant of Ce:YIG Faraday sensor element through compositional modification. Due to the Ce3+ ions substitution, the specific Faraday rotation of Ce0.29...
The dynamics of electro hydraulic servo system (EHSS) in pipe expanding process are highly nonlinear. The system may be subjected to large extent of model uncertainties, non-smooth and discontinuous nonlinearities of asymmetry proportional-servo valve, asymmetry cylinder, friction, etc. To address these challenging issues, the nonlinear character of asymmetry cylinder actuated by asymmetry valve was...
E-commerce on the Internet provides a high level of flexibility and openness, but it still has many drawbacks due to the heterogeneity of the exchanged information. Web Services have added a new level of functionality on top of current Web, enabling the use and combination of distributed functional components within and across company boundaries, but they offer only syntactical description that are...
