Based on the phenomenon of serious tensile-shear failure bolts and cables, domestic foreign scholars’ research mechanical properties cables has gradually changed from pure tensile to performance. To reduce long-term bolt cable breakage accidents in deep soft rock tunnels coal mines, we independently developed a new type support material—anchor with C-shaped tube corresponding test system. The s...

the combination of flexural frame and shear wall is one of the suitable systems to apply in reinforced concrete buildings. the deflections of flexural frame become limited due to the high stiffness of wall and the interaction of these systems. tall buildings even higher than fifty stories can be designed by using frame- wall systems. with respect to special behavior of flexural frame or shear w...

this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

The 56-kDa protein of Rickettsia tsutsugamushi, which is located on the rickettsial surface, has been shown to be an immunodominant antigen. The gene that encodes the 56-kDa protein of R. tsutsugamushi Boryong (bor56) was cloned. Sequencing revealed an open reading frame of 1,602 bp encoding 534 amino acids with a molecular weight of 56,803. The 56-kDa protein of R. tsutsugamushi Boryong (Bor56...

Generally, the finite element method is a powerful procedure for analysis of tall buildings. Yet, it should be noted that there are some problems in the application of many finite elements to the analysis of tall building structures. The presence of artificial flexure and parasitic shear effects in many lower order plane stress and membrane elements, cause the numerical procedure to converge in...

0 Robot control using a real-time visual feedback has been recently improved (visual servoing.) Conventional vision systems are too slow for these application, because the CCD cameras are restricted to the video frame rate ( N T S C 30Hz, PAL 25Hz). To solve this problem, we have developed a 1ms vision system, to provide a far faster frame rate than that of the conventional systems. Our 1ms vis...

partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...
