ZigBee networks based on the IEEE 802.15.4 standard are designed for wireless sensor and control networks with low-cost, low-power consumption, and low-data rate. To join in a ZigBee network with the tree topology, the hardware requirement of a device is simple and low threshold. However, a device may become an isolated node due to constraints of(More)
Information and communication technology (ICT) profoundly impacts on environment because of its large amount of CO<inf>2</inf> emissions. In the past years, the research field of &#x201C;green&#x201D; and low power consumption networking infrastructures is of great importance for both service/network providers and equipment manufacturers. An emerging(More)
Network-on-chip (NoC) architectures provide a high-performance communication infrastructure for system-on-chip designs. Circuit-switched networks guarantee transmission latency and throughput, and hence are suitable for NoC architectures with real-time traffic. In this paper, we propose an efficient integrated scheme which automatically maps application(More)
The effect factors of acoustical properties and tire/road noise, such as cruising speed, vehicle categories, pavement surface type and pavement condition are uncertain. Many of the exiting prediction models for acoustical properties and traffic noise have still application limitations and accuracy problems. Therefore, acoustical properties and tire/road(More)

Mesoporous titanium dioxide materials were prepared using a nanocasting technique involving silica SBA-15 as the hard-template. At an optimal loading of titanium precursor, the hexagonal periodic array of pores in SBA-15 was retained. The phases of titanium dioxide could be easily varied by the number of impregnation cycles and the nature of titanium(More)
