To meet the needs of employees growing, training costs increase and better resources sharing, a UML-based instant communication system of enterprise was established to implement study, exchange and training inside enterprise. The paper analyzes in detail the UML modeling based on the system requirement and designs the use-case model, static model and dynamic model which give a kind of visual framework...
To implement the informatization management of water supply pipe network, the paper introduces the general design of a wireless monitoring system for water supply pipe network based on ARM and GPRS technology, including the implement of the hardware and software of the monitor terminal. The monitor terminal was designed based on LPC2210 MPU and could collect the data of supply pipe network such as...
High cost and power consumption are the disadvantages of traditional two-wired meters, the paper introduces a design method for high precise and low cost multi-function meter. The system used ultralow power MSP430F4152 microprocessor as the main control chip which has 10bits A/D module. In order to improve the measure resolution, a conversion circuit was designed to extend 10bits A/D module to 12bits...
A mathematic model based on RBF neural network and genetic algorithm for multivariable optimal control with the lowest operational cost by limiting total substrate discharge in activated sludge process are discussed in this paper. It shows that the RBF neural network has preferable convergence for modeling the process. Genetic algorithm is an effective searching method to resolve the optimal problem...
