This work offers a framework for predicting the delays of individual design paths at the post-silicon stage which is applicable to post-silicon validation and delay characterization. The prediction challenge is mainly due to limited access for direct delay measurement on the design paths after fabrication, combined with the high degree of variability in the process and environmental factors. Our framework...
This article is though discussed numerical simulation to predict the migration of uranium and strontium in shallow strata in the soil. The result indicated that the uranium will migrate out between 9777a ∼ 13587a in landfill T1, and the uranium will migrate out between 62150a ∼ 91703a in landfill T2. But the strontium won't migrate away completely. Therefore it is need to take necessary measures to...
A self-exciting vibration model of a single-degree-of-freedom blooming mill, part of the main blooming drive system, is presented and its dynamical equation is established. According to the bifurcation, phase portrait and Poincaré portrait, the nonlinear dynamical motions are studied in one parameter. The software Matlab/Simulink is used to create a block diagram of the circuit system. The result...
