All the structures (bridges, offshore structures, aeroplane, ships, submarines, space vehicles and civil structures) need to qualify the dynamic loading conditions.
In short it can be concluded that by measuring the material dynamic fracture properties we can build reliable engineering structures. 6.

Wireless Sensor Network Programming Based on IEEE802.15.4 Haifei Si and Zhong Yang Institute of Mechanical and Electrical Engineering, Jinling Institute of Technology, Nanjing, China 211169 sihaif@jit.edu.cn, yz@jit.edu.cn Keywords-wireless sensor network;IEEE802.15.4 standard; networking scheme Abstract—Wireless sensor network (WSN) requires a wireless communication technology which is low in cost, low in power and easy to be implemented.
Conclusion The wireless sensor network, as a self-organized, dynamic and topological network, requires no fixed basic network facility because of the distributed multi-hop wireless communication system without basic frame; the node with routing function can be utilized to dynamically and flexibly make up of a network; the network will be widely applied to military and civil fields; but the mobile self-networking brings about limitation in network resource such as channel capacity and energy consumption.

Increasing the lifetime of these structures is a continual challenge to engineers by reducing the cost of the technological process and the recycling or eliminating of refractory waste.
The most popular criteria for refractories are shown herein, these parameters being widely used by the engineers to rank the resistance of materials to thermal shock and (1) and (2) where E is the Young’s modulus, the Poisson’s ratio,the tensile strength, the thermal expansion coefficient and the fracture surface energy .
