In the society with the rapid development and popularization of computer technology, the management information system has become the hot field of software development. It runs stably in the browsers, like IE6, IE7, IE8, IE9 and FireFox, with high efficiency, sound security, friendly interface and simple operation. It has done research on the design and realization process of HTML5 off-line data storage on the Android platform. Under the Eclipse integrated development environment, with Android SDK and HTML5 grammar, develop the system, which realize the functions of off-line storage, addition, deletion and modification of user data. It enables the application of HTML5 of Android platform and has made detailed analysis on the Android platform and HTML5 application module. The result indicates, the webpage application design of HTML5 conducted on the Android platform, is simple and fast, which can better meet the demand of Android cellphone users. © (2014) Trans Tech Publications, Switzerland.

Large file uploading is a problem often occurs in Web applications. Existing uploading components does not support Resume-broken-transfer while most of them cannot display uploading progress, also Cross-platform compatibility is not very well. This paper adopts Fragments-access, Asynchronous-uploading strategy, implements large file Resume-broken-transfer using ADODB. Stream and XMLHttp, obtains higher rates of transmission and real-time display of uploading progress and good Cross-platform compatibility, meets the large file uploading needs in web applications. © (2014) Trans Tech Publications, Switzerland.

This paper describes the application of the complex variable meshless manifold method (CVMMM) to stress intensity factor analyses of structures containing interface cracks between dissimilar materials. A discontinuous function and the near-tip asymptotic displacement functions are added to the CVMMM approximation using the framework of complex variable moving least-squares (CVMLS) approximation. This enables the domain to be modeled by CVMMM without explicitly meshing the crack surfaces. The enriched crack-tip functions are chosen as those that span the asymptotic displacement fields for an interfacial crack. The complex stress intensity factors for bimaterial interfacial cracks were numerically evaluated using the method. Good agreement between the numerical results and the reference solutions for benchmark interfacial crack problems is realized. © 2014 Hongfen Gao and Gaofeng Wei. Source
