-world optimization (SWO), was designed to solve the global optimization problems, which was inspired from small-world theory and six degrees of separation principle in sociology. Firstly, the solution... algorithms have become a very active area of research. Researchers and engineers from system engineering, automation, computer science, management engineering, mining and mechanical engineering and so......
improved as compared to RTR samples (320 MPa and HV 115). The increase in hardness and UTS of CR samples after annealing at 200 °C was due to precipitation of β'' from Al matrix, which imparted higher... with the grain size ranging from 100 nm to 1 μm, exhibit very high strength and hardness but low ductility as compared to their bulk counterpart. The combination of high strength and ductility could......
and the experimental results were close from each other. The microhardness distribution maps were in a good conformity with the effective plastic strain contours and verifying the 3D FEM simulations results. The ECAP... the commercial software DEFORM-3D V.6.1 [26]. DEFORM-3D is a finite element method (FEM) program based on the process simulation system to analyze different metal forming processes. Unlike, most FEM......

mechanical properties, severe plastic deformation (SPD) has attracted much attention from the extensive researchers during past decades. Except for the conventional deformation methods such as rolling [1...- extrusion) is a further development of Conform, and liquid metal in Castex is used to replace solid feedstock in Conform [12-14]. However, little work is available about the combination of Castex and ECAP......
, the research object has changed from sampling data to overall data, and the goal of the research has shifted from pursuing causality to pursuing correlations [1]. We face two major tasks in the future: 1) extracting knowledge from the data deluge and 2) deriving models from the data that can learn much more than traditional approaches while still respecting our evolving understanding of nature’s laws......
from principles to practices. Many studies have demonstrated that WMA technologies work effectively with AR pavement in different ways, alleviating the concerns of potential higher emissions of AR..., reclamation in pavement engineering refers to the process of reclaiming road materials from loss or from a less useful condition; recycling involves processing waste materials from other fields into useful......
