China has achieved the goal of building a moderately prosperous society in a well-rounded way by 2020.At this stage, effectively dealing with poverty and not returning to it has become the bottom-line task of rural revitalization.The purpose of this study is to construct a poverty-return early warning and evaluation system for X and Y counties in G
RR Lyrae Stars in M4
Observations by Kepler/K2 have revolutionized the study of RR Lyrae stars by allowing the detection of new phenomna, such as low amplitude additional modes and period doubling, which had not previously been seen from the ground.During campaign 2, K2 observed the globular cluster M4, providiing the first opportunity to study a sizeable group of RR L
Reliable Service Function Chain Deployment Method Based on Deep Reinforcement Learning
Network function virtualization (NFV) is a key technology to decouple hardware device and software function.Several virtual network functions (VNFs) combine into a function sequence in Twin Coverlet Set a certain order, that is defined as service function chain (SFC).A significant challenge is guaranteeing reliability.First, deployment server is se
An Overview of the Interactions Between Reinforcements and Al Matrices with Si, Cu And Mg as Alloying Elements in Aluminum Matrix Composites: Case of Oxide Reinforcements
Abstract Oxides (Al2O3, SiO2, TiO2, ZrO2, Y2O3, CeO2, MgO) are among the most used reinforcements for Aluminum Matrix Composites (AMC); while the combination of Al with Si, Cu and/or Mg excels among the alloying systems used as matrices.Some works in literature study the effects of the reinforcements and the alloying elements on the composites manu
