This paper presents the results of Non-Destructive Testing on Magnetically Impelled Arc Butt (MIAB) welded mild steel tubes of 27mm OD and 1.5mm thickness.As part of this work, the tests covered were radiography, liquid penetrant, and magnetic particle testing.The testing results indicate that porosity, penetration levels and the defects found are
Deep neural networks have been successfully applied in the field of image recognition and object detection, and the recognition results are close to or even superior to those from human beings.A deep neural network takes the activation function as the basic unit.It is inferior to the spiking neural network, which takes the spiking neuron model as t
To study the influence of different liner structures and materials (copper, steel, and tungsten) on the forming characteristics of multiple explosively formed projectile (MEFP) with integrated liner and shell designs, three types of liners with different structures were designed.LS-DYNA was used for numerical simulation, and the results show that t
Small islands in the Mediterranean Sea, although endowed with exquisite land and maritime natural and cultural resources, are in most cases lagging behind areas, mainly due to insularity.Through their long history, many of them are strongly interwoven to events of European or even global significance, e.g., World War (WW) I and II.Such events have
