finally the paper introduces the programming implementation of the proposed method and mix-language programming techniques . numerical examples are used to prove the proposed sensitivity analysis method 最后,在程序?qū)崿F(xiàn)上,闡述了混合編程技術及程序的實現(xiàn)過程,給出了數(shù)值算例,對所提出的靈敏度分析方法進行了驗證。
based on stable reliability-based design theory and sensitivity analysis method, research on stable reliability-based sensitivity design for compressive bar is carried out and a numerical method for reliability based sensitivity design is presented 摘要在穩(wěn)定可靠性設計理論與靈敏度分析方法的基礎上,研究了壓桿穩(wěn)定可靠性靈敏度設計問題。
power sensitivity is defined and some related mathematical models are deduced, which bring on a set of theoretic power sensitivity analysis methods for combinational circuits . experimental results verify that the method can be used for dynamic power and leakage power 另外文章還提出了一種靜態(tài)功耗壓縮估計方法和一種雙閾值電壓快速優(yōu)化方法,它可以很好地用在低漏電電路的設計中。
when damaged elements increase at the same time and the number of element is much more than that of measured modes, the sensitivity analysis method can ? give desired results . therefore, a method which can identify damage though two steps, location and extent, is put forward 當結構中同時損傷的單元數(shù)目較多,以及結構單元數(shù)目遠大于實測的模態(tài)階數(shù)時,靈敏度分析法的識別結果嚴重下降,本文提出損傷識別的兩步法,將結構的損傷分為定位和定量兩個步驟,有效地改進了識別效果。
after probable damage location through msecr, the method based on the sensitivity of orthogonality conditions gives good predictions of damage . this method overcomes the natural defect of the concept first order approximation of the ordinary sensitivity analysis method . but this method needs complete measured modes 為克服靈敏度分析法一階近似的本質(zhì)缺陷,基于正交條件靈敏度分析法,利用msecr對結構的損傷進行粗略定位后,給出了準確的識別結果,但這種方法的缺點是需要完備的實測振型。
