Reinforcing Effect of Thin-wall at Serviceability Condition

Laboratory Model Tests to Study the Behavior of Soil Wall Reinforced by Weak Reinforcing Layers

In this paper we suggest a method to calculate the first integrals of a special system of the first order of differential equations. Then we use the method for finding the solutions of some differential equations such as, the differential equation of RLC circuit

Reinforcing Multi-Wall Carbon Nanotubes by Electron Beam Irradiation

To prepare the samples for Transmission Electron Microscopy (TEM) imaging and Atomic Force Microscopy (AFM) measurements, as-grown carbon nanotubes were dispersed in isopropanol and sonicated using HD2200 homogenizer with a power of 20W for 5 minutes. To characterize the nanotubes by HRTEM, a droplet of the suspension was put on a Cu TEM grid with a lacey C film. Alternatively, we deposited a d...

Two Alternative System Reliability Approaches to the Serviceability Condition Assessment of Spillway Gate Systems on Dams

CFD simulation for segregation behavior of a ternary mixture in a bubbling fluidized bed: effect of solid wall boundary condition

Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...

Scale effect of slip boundary condition at solid–liquid interface

Rapid advances in microelectromechanical systems have stimulated the development of compact devices, which require effective cooling technologies (e.g., microchannel cooling). However, the inconsistencies between experimental and classical theoretical predictions for the liquid flow in microchannel remain unclarified. Given the larger surface/volume ratio of microchannel, the surface effects in...
