In this paper a novel framework is presented for 2 - d shape interpolation using the intrinsic shape parameters of a piecewise linear curve based on skeleton 本文基于骨架概念,根據(jù)多邊形內(nèi)在量插值思想給出一個新穎的二維形狀插值算法框架。
Abstract : the problem of approximating a given piecewise linear curve by another coarser one consisting of fewer line segments is discussed . an efficient algorithm is presented and analyzed 文摘:討論了用較少的折線段來表示精細折線邊界的問題.提出了解決該問題的一個有效算法,并對該算法進行了分析
Through the study of this problem , that an amendment method is presented for non - linear curve of equivalence pile head . the method can be used to analyze the three dimensional effect on nsas and commercial software ansys 本文針對這一問題進行了分析,并提出樁頭等效非線性曲線的修正方法,并在nsas和大型商業(yè)軟件ansys上均可以實現(xiàn)樁-土-結構共同作用的空間效應分析。
To guarantee the validity and speediness insimulation , the back - emf is generated using piecewise linear curves . in the double loop of control system , a pi controller is adopted in the speed loop and a hysteresis current controller is adopted in the current loop 為保證仿真快速性和有效性,模型采用分段線性法生成梯形波反電動勢,系統(tǒng)采用雙閉環(huán)控制:速度環(huán)采用pi控制,電流環(huán)采用滯環(huán)電流控制。
The results indicate that the ratio of span to rise , the ratio of reinforcement and the stretching controlling stress are the three primary influencing factors to the failure pattern of the slab . in addition , the relationships between the ratio of deflection to span and the ratio of span to rise and the stretching controlling stress submit to linear curves , the relationship between the ratio of deflection to span and the ratio of reinforcement submits to a quadratic parabola curve 運用數(shù)值分析程序計算了175組不同跨高比、配筋率、張拉控制應力的中強( 1270mpa )螺旋肋鋼絲預應力空心板,結果表明跨高比、配筋率、張拉控制應力是影響空心板破壞形態(tài)的主要因素,且構件撓跨比與跨高比和張拉控制應力呈線性關系,與配筋率呈二次拋物線關系。
