The stress state at an atomic level and its governing physics inside a random alloy are essential elements in developing a model for solid solution strengthening in random alloys, which is one of the primary strengthening mechanisms of high-entropy alloys (HEAs).Through first-principles calculation, we investigated the atomic stress in fcc and bcc
Purpose.The article considers definition of the bond types occurring in a modified cement concrete matrix, and the evaluation of the quality of these links in a non-uniform material to determine the geometrical and physical relationships between the structure and the cement matrix modifiers.Methodology.To achieve this purpose the studies covered th
In recent 20 years, the rapidly development of thermoelectric materials promotes thermoelectric s application in large scale cooling area, i.e.air-conditioner.To provide quiet working environment for the driver of high-speed railway, a kilowatt scale air-conditioner was designed.Firstly, a novel thermoelectric cooler with maximum cooling capacity o
The simulation of the authentic evacuation process is conducive to accurately evaluate the casualties of PHYTONECTAR buildings under earthquake.This study improves the traditional cellular automata model to simulate the crowd evacuation process in buildings under earthquake.The modified model simulates the attraction of exits to crowds, herd behavi
In the past 5 years the Safety Engineering Group of BASF had determined the static equivalent pressures (pstata) of the eight detonative pressure scenarios which explosive gas mixtures can exhibit in long and in short pipes.More precisely, for different combustibles the pstat-values of the corresponding ternary mixtures combustible/O2/N2 were deter
