1.The Distinct Element Method(DEM)is a discontinuum-based numerical method especially applicable to solve the discontinuity problems in jointed rock mass.
2.According to the problem of position discontinuity using GPS in city cars, a scheme that GPS is combined with DR which is composed by piezoelectric gyro and milemeter is put forward.
6.This refers to the use of statistical tricks, such as instrumental-variable analysis, natural experiments and regression discontinuity, which are designed to tease out causal relationships from data.
7.However, as shown in Figure 1, the drawback of this approach is the inherent discontinuity of adjacent springs, which does not reflect the mechanical properties of foundation soil materials.
8.In addition, the discontinuity layout optimization (DLO) numerical approach has its unique advantages in the study of tunnel structure stability, but this study does not involve this aspect.
9.And that is because there is an absolute discontinuity between the economy of the seller of medicines and the economy of the buyer, as there is in the health industry as a whole.
10.Changes in the liquidity function itself; due to a change in the news which causes revision of expectations, will often be discontinuous, and will, therefore, give rise to a corresponding discontinuity of change in the rate of interest.
