RISRoot Cohesion Estimation of Riparian Trees Based on Model Uncertainty Characterization
Publisher: American Society of Civil Engineers
Abstract: The mechanical reinforcement effect of roots on soil shear strength is widely recognized and can be used in slope stability analyses based on the limit equilibrium or finite-element method. Although some advanced root ...
Pore-Scale Study of the Thermochemical Process in Porous Media With Immiscible Phase by Lattice Boltzmann Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reactive flow happens in carbonate rocks which are porous media during acidification. In this study, a thermochemical dissolution model based on the lattice Boltzmann method (LBM) is established to investigate the complex ...
The Impregnating Reduction Method for Synthesis of Pt–Ru Nanoparticles and Its Catalytic Performance for Methanol Electro oxidation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welldispersed and low Pt content Pt–Ru/C nanoparticles were prepared by a developed impregnating reduction method with sodium citrate as stabilizer. The asprepared Pt–Ru/C catalysts were characterized by Xray diffraction ...
Global Wavenumber Spectrum with Corrections for Altimeter High-Frequency Noise
Publisher: American Meteorological Society
Abstract: he altimetry wavenumber spectra of sea surface height (SSH) provide a unique dataset for testing of geostrophic turbulence. While SSH spectral slopes of k?11/3 and k?5 are expected from theories and numerical simulations, ...
Connecting Microstructures for Multiscale Topology Optimization With Connectivity Index Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the rapid developments of advanced manufacturing and its ability to manufacture microscale features, architected materials are receiving ever increasing attention in many physics fields. Such a design problem can be ...
Two-Dimensional Numerical Simulation of Rock Fragmentation by TBM Cutting Tools in Mixed-Face Ground
Publisher: American Society of Civil Engineers
Abstract: In the study described in this paper, a general particle dynamics (GPD) code was developed to simulate rock fragmentation by tunnel-boring machine (TBM) cutters in mixed-face ground. In the GPD code, a novel algorithm of ...
Reliability Assessment of Tunnel Based on P-Wave Seismic Velocity
Publisher: American Society of Civil Engineers
Abstract: This paper aims to propose a new method to analyze the stability of a tunnel using P-wave seismic velocity (Vp) with the help of the Tunnel Seismic Prediction 23 plus system (TSP23PLUS). On one hand, the relationship between ...
Experimental Study on Rockfall Impact Force Applied to Frame Shed Tunnels
Publisher: American Society of Civil Engineers
Abstract: A model experiment is performed to test the rockfall impact force applied to frame shed tunnels under the protection of different types of cushions embedded on tunnel roof slabs. The changing rule of impact force induced ...
The Effect of Solvent on the Capacity Retention in a Germanium Anode for Lithium Ion Batteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thin and mechanically stable solid electrolyte interphase (SEI) is desirable for a stable cyclic performance in a lithium ion battery. For the electrodes that undergo a large volume expansion, such as Si, Ge, and Sn, the ...
