Accurate prediction and reasonable warning for dam displacement are important contents of safety monitoring. However, it is difficult to identify abnormal based on deterministic point results. In response, this paper proposes a model that integrates several strategies achieve high-precision interval displacement. Specifically, the realized in three stages. first stage, Extreme gradient boosting...

In this paper, a methodology is presented for obtaining the plastic anisotropy of bulk metallic materials using cross-sectional indentation. This method relies on spherical indentation on the free edge of a specimen, and examining the out-of-plane residual deformation contour persisting on the cross-section after unloading. Results obtained from numerical simulation revealed that some important...

after springs production, different residual stresses are created in the inner and outer surfaces of spring wires. some of these stresses for example compressive residual stresses are useful and some are harmful. the effects of vareation of these stresses are caused spring relaxation and decrising in their free length when they are loaded intermittently. for review this phenomena in this resear...

The purpose of this study was to evaluate the degree and amount of movement of the abutment tooth and denture base influenced by the direct retainer of distal extension removable partial denture and the location of functional loading, then to suggest direct retainer design with minimal adverse effect and with optimum functional loading location for residual tissue. The displacement of the abutm...

A trial comparing the use of Bier's block and the direct infiltration of the fracture site with local anaesthetic was carried out to assess their effectiveness in the reduction of Colles' fracture. This showed Bier's block to be superior in terms of patient acceptability and in ease of reduction. The results of the reduction were also significantly better using the Bier's block, as judged by th...

This paper treats the interactions between a main crack and a rnicrocrack in an anisotropic piezoelectric solid. Based on the Green's function approach and the principle of superposition, a system of singular integral equations for the unknown temperature discontinuity defined on each crack face is developed and can be solved numerically. In the analysis, the residual heat flux, stress and elec...

This paper discusses the efficiency of a compression scheme for video sequences that jointly encodes groups of pictures. Our approach, motion-compensated transform coding, applies a KLT to decorrelate a set of motion-compensated pictures for efficient encoding. The theoretical investigation utilizes a signal model for inaccurate motion compensation and provides a performance comparison to motio...
