In the paper, the fast-charging strategy of correcting slope iteratively is put forward to shorten charging time and extend operation lifecycle of electric vehicles. The method could adjust the slope of charging current in real-time to make actual current close to or equal to the battery's acceptable maximum current. And this increased the charging rate and avoided that batteries were overcharging...
With the emergence of SaaS, enterprises are looking for available application construction approach to quickly adopt to new business requirements and reduce application development and maintenance costs. To speed the application construction and guarantee multi-tenant configurability in large amount, a flexible design is of major importance. This paper puts forward the concept of abstract SaaS application...
Software-as-a-service emerges as a new delivery model for the software development and applications. In multi-tenancy applications, tenants can customize and adjust the corresponding services shared by tenants based on their business requirements with strong elasticity and expansibility. As services do not exist independently, the resolving of service dependencies in practical multi-tenancy applications...
The present situation and characters of rural sewage were described. Accordingly, the index system for evaluating the performance of rural sewage treatment facilities was proposed, which consisted of two categories-technology and economy. The Delphi method was employed to decide the weight of index. The data was standardized correspondingly and finally the model was construed for evaluating the comprehensive...
In this paper, A production environment monitoring system based on GPRS-Internet was designed and implemented. The system uses ARM9 embedded CPU as its host and realizes monitoring function and man-machine interface by using cross-platform C++ graphic interface library Qt in Linux OS. It sends collected data to remote server by GPRS model and clients realize real-time and long distance monitoring...
With the development of the embedded technology, the Zigbee communication protocol is used in more and more application systems. In this paper we proposed a scheme to realize the intellectualized management system of garage in the community. In the scheme, we combined the embedded technology with the Zigbee wireless communication technology, utilized the license plate recognition system to recognize...
With Ajax firmly established as a widespread Web application-development technique, it is possible to build GPS monitoring system based on B/S architecture, so a large number of Web GPS monitoring systems are released recently. This article analyzes the common GPS monitoring systems based on AJAX and points out three main existing weaknesses. Then the article introduces how to use AJAX push pattern...
