problem. 2) The soil in the free zone of a geogrid (i.e., the area significantly influenced by cyclic drying and wetting in the reinforced soil unit) is fully saturated. ZHAN et al [23] monitored......
for estimating CMFs using an EB before-after study, then documents the process for examining the accuracy of standard errors of the CMFs. 2.1 EB method for estimating CMF GROSS et al [3] provided......
15(b) gives the relationship between lgN(δ) and lgδ for SCTO specimen 4. D is the slope of the fitting line, and D=1.038 in Figure 15(b). According to ROSE [46] and BHAT et al [47], the DSIFfor......
a software architecture that can support dynamical task scheduling for improving the robustness of the system in surveillance tasks. BRUNO et al [14] recommended that robot architecture design should meet......
) good reproducibility and low cost in synthesis [12-16]. Recent work on NFAs has contributed to some breakthroughs in OPV [17, 18]. Especially after the report of Y6 by ZOU et al [17], OPV has reached......
has only two levels for each factor and cannot meet the accuracy requirement. In addition, the uniform design (UD), proposed by FANG et al [21] based on pseudo Monte Carlo method in number theory......
by the central government from 2016 [6]. It is required by law that the cyanide- containing solid wastes must be detoxified to a limit of 5 mg/L total CN before being discharged to tailing ponds [7,8... taken out and cooled in air. The mixture and clinker were weighed and the masses were recorded, respectively. According to DONG et al [35], O2 played an important role in the decomposition of sodium......
