Abstract: Axial static stiffness is a main technical indicator for the ball screw feed drive system, and the elastic deformation outside the Hertz contact zone of the system affects its axial static stiffness. However, the influence ...

Abstract: In conventional discontinuous deformation analysis (DDA), the procedure called open–close iteration is adopted to enforce the contact condition, which needs to repeatedly fix and remove the artificial springs between blocks ...

Abstract: Abstract. This study presents a novel artificial neural network approach for determining material parameters from single spherical indentation test data, addressing the fundamental nonuniqueness problem inherent in ...

Abstract: A scratch intersection based material removal mechanism for CMP processes is proposed in this paper. The experimentally observed deformation pattern by SEM and the trends of the measured force ...

Abstract: A high performance and cost effective biosensor is designed using a radial contour-mode disk resonator (RCDR). This sensor measures tiny biological mass attached on a disk vibrating at a high ...

Abstract: In order to the prevent and control construction dust, and to avoid secondary pollution, on the basis of single factor experiment, the viscosity, surface tension, determination of water retention, and water absorption rate ...

Abstract: This paper reports a case of a large-scale underground powerhouse whose high wall faces a significant stability problem owing to the presence of thin-layered, steeply dipping strata. The local failures are widely distributed ...

Abstract: Based on the fact that there are nonstrict priority left-turning maneuvers at signalized intersections with a permitted phase in some countries, this study proposes a left-turn unit-based approach to estimating permitted ...

Abstract: Methane and other gases released from soft sediments are among the main sources of greenhouse gases in the atmosphere. In this paper, a growth model for isolated bubbles in the sediments was established based on the theory ...

Abstract: Porous carbon with a high surface area has attracted wide attention in energy storage systems due to its fast charge−discharge rate and exceptional rate capability. However, it is still a challenge to design electrochemical ...
