Human vision has marvelous ability in extracting linear features from images, such as roads, rivers and so on. In this paper we present a new method to simulate this ability. Our method is based on some general grouping factors arising at two levels. At the first level, grouping factors are identified as direct bar-bar interaction and orientation interaction. Bar-bar interaction is shortranged ...

Scrap steel fiber concrete (SFRC) is a new kind of material, which uses the scrap from tire as reinforced FRP bar concrete, replacing or partially traditional and synthetic fiber. This paper summarizes research status waste at home abroad, including mechanical properties compressive tensile resistance, mixing amount use requirements fiber, finally development prospect forecasted

Waters’ variant of the Boneh-Boyen IBE scheme is attractive because of its efficency, applications, and security attributes, but suffers from a relatively complex proof with poor concrete security. This is due in part to the proof’s “artificial abort” step, which has then been inherited by numerous derivative works. It has often been asked whether this step is necessary. We show that it is not,...

The aim of this paper is to present results of testing a full scale reinforced concrete T connection by static loading. The connection is a T connection representing a beam-column connection. The beam and column had a square cross section with a 300 mm dimension. The height of the column was 2.9 m and the clear beam length was 1.4 m. The connection was initially tested to failure. Galvanised st...
