Aiming to survey scenarios of offshore projects with difficult horizontal elevation transmission and long-distance, all-weather monitoring operations, a total station, trigonometric leveling based on dynamic compensation is proposed. The feasibility this method was verified by an outdoor experiment, the range transverse coverage accuracy reached quantitatively analyzed. results indicate that sh...

The suspension bridges in mountainous areas are commonly designed with asymmetrical overall layouts to match the terrain and construction under limited space. However, effects influences of asymmetry parameters on bridge performance have yet be thoroughly investigated. To address this gap, based a real-world main span length 700 m, paper first presents an improved shape-finding method that can ...

about 30 viewers, a driver is selected to direct the robot's path and the pan and tilt of the panospheric imagery. Other audience members choose what technical information is overlaid on the display. In addition, imagery and robot status are available in real time on the Internet. The Science Center also features kiosks that describe the Trek, various technologies utilized by the robot, the sci...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...

The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake.  In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...

introduction: the purpose of this in vitro study was to compare the accuracy of the new electronic apex locator raypex5 with radiography for working length determination of straight and curved root canals. materials and methods: twenty straight and single canals of maxillary central teeth and twenty curved mesiobuccal canals of mandibular molar teeth were used. access cavities were prepared and...

The AASHTO code of practice for design of bridges shows that the ductility level for foundation is given equal to one. Bridges are classified in three classes. For class of essential and normal bridges a question for not to use ductility level due to the importance of bridges’ costs is become an important item in different countries particularly in Middle east. This paper aimed to study on pe...
