Based on the Internet of Things technology, this paper proposes building a cross-border e-commerce logistics supervision system and determines the evaluation index system from the overall framework design of the system, supply chain supervision process optimization, risk supervision optimization, and system order degree optimization.First of all, t
It is absolutely necessary to expand high pressure lancing area in order to ensure the operation safety of steam generator transfer heat tubes Latch in nuclear power plants.Considering the structure at the secondary side of the steam generator, and in compliance with the guidelines of reducing cost and increasing the compatibility, the reverse lanc
The estimation of crop yield is a compelling and highly relevant task in the scenario of the challenging climate change we are facing.With this aim, a reinterpretation and a simplification of the Food and Agriculture Organization (FAO) fundamentals are presented to calculate the fresh biomass of forage crops.A normalized difference vegetation index
This study is a contribution to our understanding of the mechanical behaviour of dental implants through the use of the finite element and the photoelastic methods.Two internal connection and bone level dental implants with different design have been analysed (M-12 by Oxtein S.L., Zaragoza, Spain, and ASTRA, from Dentsply Sirona, Charlotte, NC, USA
