RISElectrical Contact Resistance at the Carbon Nanotube/Pd and Carbon Nanotube/Al Interfaces in End-Contact by First-Principles Calculations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reported in this paper is a quantum mechanics study on the electronic structure and contact resistance at the interfaces formed when an open-end single-walled carbon nanotube (CNT) is in ...
Type Synthesis of Parallel Mechanisms Having the Second Class GF Sets and Two Dimensional Rotations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the introduction of generalized function sets (GF set) to represent the characteristics of the end-effectors of parallel mechanisms, two classes of GF sets are proposed. The type synthesis ...
Relationship Among Input-Force, Payload, Stiffness, and Displacement of a 6-DOF Perpendicular Parallel Micromanipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micromanipulators play an important role in the precision engineering field from optical stages to micro-electromechanical systems for their excellent performances. In this paper, a 6-DOF perpendicular ...
On the Extension of a Fourier Descriptor Based Method for Planar Four-Bar Linkage Synthesis for Generation of Open and Closed Paths
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier work, we have presented an efficient method for synthesizing crank-rocker mechanisms that are capable of generating perceptually simple and smooth low harmonic closed curves. In ...
Heavy-Metal Accumulation in Low-Sludge Wastewater Treatment Technique: Sonication-Cryptic Growth
Publisher: American Society of Civil Engineers
Abstract: This paper used a sonication-cryptic growth technique in sequencing batch reactor (SBR) to reduce sludge yield and then analyzed the accumulation of eight typical heavy metals in sludge, namely, Hg, Cr, Ni, Cu, Zn, As, Cd, ...
Upper-Bound Finite-Element Analysis of Characteristics of Critical Settlement Induced by Tunneling in Undrained Clay
Publisher: American Society of Civil Engineers
Abstract: An interesting operation has been developed to estimate the critical normalized surface settlement for shallow tunnels in undrained clay (idealized as a homogeneously Tresca material). The upper-bound finite-element method ...
Novel 3D Failure Criterion for Rock Materials
Publisher: American Society of Civil Engineers
Abstract: The failure criterion of rock material has been used in geotechnical engineering to assess the failure behavior of rocks under complicated stress conditions. In the present study, a new failure criterion is proposed; it ...

Convergence Compensation for Space Contact Semiphysical Simulator Based on Mechanical Structure Dynamics
Publisher: ASCE
Abstract: Space capturing and docking is a key technique for space on-orbit operations. The semiphysical simulator is an essential experimental facility to verify the space capturing and docking task. The simulation divergence problem ...
Disintegration Characteristics and Mechanisms of Carbonaceous Mudstone Subjected to Load and Cyclic Drying–Wetting
Publisher: ASCE
Abstract: Carbonaceous mudstone is a common embankment material with the characteristics of water softening and water disintegration, which often causes the instability of embankments. This paper presents an experimental work on the ...
