Abstract: The authors developed a valuable method for estimating the impact stress caused by dynamic load head-disk contacts. Based on existing experimental database, they extrapolated the desired radius ...

Abstract: Collaboration networks are a compilation of dynamic relationships among multiple stakeholders within and across organizations. A megaproject may involve hundreds of organizations that may be competing for a new subproject ...

Abstract: The lining rings of a shield tunnel are connected by steel bolts, which play an important role in longitudinal structural deformation during long-term operation. In recent decades, there have been increasing numbers of ...

Abstract: This study used a two-stage method to derive an analytical solution for assessing the vertical displacement of an existing pipeline caused by the undercrossing construction of a shield tunnel. The aim was to evaluate the ...

Abstract: High-momentum jets, which are the key parameter to achieve moderate or intense low-oxygen dilution (MILD) combustion may lead to insufficient residence time and high CO emissions, especially for furnaces with a forward-flow ...

Abstract: The purpose of this study was to find an effective way for in vivo measurement of joint motion and give the normal knee motion according to this method. The joint model proposed by Grood ...

Abstract: Foam is potentially a promising vehicle to deliver nanoparticles for vadose-zone remediation because foam can overcome the intrinsic problems associated with solution-based delivery, such as preferential flow and contaminant ...

Abstract: Detecting trends in hydrometerological data through the commonly used Mann-Kendall test is misleading in the presence of data autocorrelation. Autocorrelation seriously interferes with type I errors and power of trend ...
