With the development of the technology of mobile communication, smartphones have become one of the most popular ways that people get information. However some restrictions such as the screen size, ambient brightness etc. still cause some troubles to read news by smartphones. We based on Android designed an audio news software system by means of the speech synthesis technology which can afford pleasure to listen to information. Using the Andriod technology we developed the smartphone client software which can get the latest information in RSS channels by communicating with the server. Also, it can dynamically manage the RSS channels subscribed by yourself. In the design, we used the techniques of the Android UI framework and component which made the smartphone interface succinct and easy. In order to improve data store efficiency we implemented the data modification and store by transforming between the Json format and the Java object. Based on the iFLY mobile speech platform we developed the audio news player. The function of information automatic acquisition in the server made it possible that smartphones can get the latest information of the subscription channels.

Radio Frequency Identification (RFID) is an automatic identification technology that can identify the objects at a distance.This paper presents the design of remote attenance system based RFID. The system is implemented for the automation of time and attenance using a new mode of barrer-free channel. With a simple setting, the attendance system is capable of recording real time attendance, counting attendance and attenance statistics analysis. Reports and charts will be provided for the top management to make decision, annual review, and planning on man power. The applied result of the system shows that it is simple and effective.

The temperature control and crack prevention of the high dam is with very much difficulties. One important reason is that the unsmooth information causes improper measures and management, that is "four don't" for obtaining the information-not timely, not accurate, not true, not systematic; furthermore, "four top" problems during the temperature control construction process can't be controlled easily, that is: large temperature difference, large scale of drop in temperature, high rate of temperature fall, large temperature gradient, which could finally cause the generation of distress in concrete. In order to solve "four don't" to control "four tops", take informationized, automatic and intelligent technical methods, establish individual ideal temperature control curve model, temperature and flow prediction and forecasting model, temperature control effectiveness evaluation model, crack risk alarm model and other online real-time analysis models, develops key technology and processes for simulative analysis of the whole process of the whole dam, develops pervasive, stable and highly precise automatic monitoring and controlling instrument and equipment, researches and develops all software function models and subsystems , integrates a complete digital concrete temperature control intelligent monitoring system for Huangdeng Dam, realizes comprehensive, accurate and timely automatic collection of large quantity of temperature control information and relevant key factors, realizes automatic analysis, evaluation and warning and alarm as well as support of intervening measure decision for large quantity of temperature control information, realizes intelligent water cooling of the whole dam under the "non-manual intervention" ideal conditions, and improves the water cooling construction quality while reducing the construction error rate. The system dynamically and high-efficiently manages, real-timely controls and analyzes the temperature control information of Huangdeng Hydropower Dam with many characters, such as real-time, continuity, automation and intelligentization, etc., it effectively manages all links during the temperature control process of the dam, realizes online real-time monitoring and feedback control of construction, which is able to effectively solve "four don't" and control "four tops", basically realizes the temperature control and crack prevention of concrete, and improves construction quality and informatization control level of Huangdeng Hydropower Station.
