With the development of national economy, they are subjected to increasingly higher usage and heavier traffic loads.

Francesco da Paola” bridge – was opened to traffic more than fifty years ago, on March 10, 1958.
For instance, this is due either to their decreased capacity due to decay or to a increased demand with respect to when they were built (i.e., the loads and the traffic flows are higher, fewer disturbances due to traffic-induced vibrations are accepted).
Thus, performing a reliable structural assessment of a bridge becomes essential to avoid its disposal, which involves seldom-acceptable economical and safety implications, not to mention the irreparable loss of a cultural heritage artifact.
The developed system for structural dynamic monitoring has been named as “THOR” and it fulfills the most important international standards and guidelines in this field.

Although the inorganic thermal insulation materials’ fire safety performance is better, but in the current application of building insulation system, the main percent is still organic insulation materials because of their relatively low price, simpler and more convenient construction process.
While at the same time, there are several defects against fire prevention or control, such as more operations by fire, regular electric welding or cutting, lack of necessary fire protection facilities, untrained staff, inconvenience traffic and etc.
The principle of high-rise building fire safety design is based on self-help.
It should be important to strengthen the construction site fire safety management, such as developing the construction fire prevention programs, strengthen staff fire safety education and pre-service training, implement the fire prevention applications and eliminate initial fire hazards in time.

The Federal Aviation Administration (FAA) of the USA and the International Civil Aviation Organization (ICAO) had attached great importance to the wake vortex, so as to avoid a hazardous impact of these vortices. [2, 3, 4] They issued regulations of safe separation distances between two airplanes to maintain a safe margin from the aircraft ahead.
But these standard separations have strongly limited the capacity of many airports and cause the congestion of air traffic throughout the world.
Therefore, the alleviation of the wake vortex becomes crucial and meaningful to the flight safety for today's booming air traffic.

This is not only conducive to traffic safety, but also can reduce the number of lightings and the waste of resources.
Anti-sliding performance of asphalt pavement is an important indicator to ensure road traffic safety.
We use the wet wheel wear test to evaluate resisting wear performance of light-colored pavement, the test results are in the following. ①From the datum, the value of wear which is between 400 ~ 530g/m2, is satisfied the qualified value which is less than 800g/m2 that the American Society for Testing and Materials (ASTM) and the International Slurry Seal Association (ISSA) suggested.
(4) The method to measure the light-colored performance did not take into account the traffic exists in operation.

The MUAV presented in this paper is designed to carry out missions like traffic monitoring and surveillance, therefore it is expected to behave like a transport aircraft.
A factor of safety of 1.5 is taken into account to the prescribed limit load to make the design loads on the wings.
Therefore, after taken into account the limit load factor and the safety factor, the maximum maneuvering load the wing structures have to withstand without breaking is 58.86 N.
The design load (maximum maneuvering load) is obtained by multiplying the lift load obtained from E.q. 1 with the limit load factor, n and safety factor, S.F

Machine vision perception technology is widely used in the vehicle’s active safety system.
Introduction For taking vertical control of the moving vehicle in the active safety system, it's needed to inspect the moving vehicles ahead to give information for further motion estimation and tracking.
Fig. 5 The result of symmetry detection of edges extracted with Sobel operator Conclusions In the view of vertical control of vehicles, moving vehicle ahead is the main threat to traffic safety.
