Abstract. Based on the problems caused by current automatic irrigation system with a large number of cables, such as installation, maintenance, and difficult expansion, this paper proposed a wireless integrated irrigation control system and developed a wireless intelligent valve controller which can satisfy the requirements for agricultural irrigation in our country. The controller consisted o...

In this paper a fuzzy controller is proposed to regulate the intake manifold pressure and the fresh mass airflow of diesel engines simultaneously. The instrumentation set usually embedded in a mass-produced passenger car has been considered. Unlike many multi-variable controllers, the proposed structure requires neither an internal model nor identification algorithms. In comparison to controlle...

E REPORT on plant visits and data collection carried out in China and present our initial preliminary findings. Eight assembly plants with their respective seat, exhaust and brake suppliers were visited in 2006. Two ECU (engine control unit) suppliers were also interviewed. Where possible, we compare our findings with the situation in China in 2003 and with current best practice worldwide. Info...

Chlorophyll content is an important indication for evaluating crop growth status and predicting crop yield. The NDVI (Normalized Difference Vegetation Index) is commonly used as an indicator in practical crop healthy monitoring. Hence, a spectroscopy-based device for indirectly measuring crop growth conditions in terms of NDVI is developed. This device consists of four channels: two are designe...

This paper introduces the prototype of design and implementation of a videoconferencing (VC) system and protocol for 3G networks based on our 3G-324M protocol stack. Efficient multimedia processing and intelligent MCUs (multipoint control unit) for efficient token transfer among a group of terminals are presented. The prototype system has shown its performance for VC in WLAN environment.
