Although insider attacks have increased rapidly in recent years and cause enormous damages, there are very few academic studies that have investigated this problem and proposed a solution.Many of these attacks are kept private for reasons such as Hobby boxes loss of prestige and advantage of competing companies.The main difference between insider a

A derailment detection algorithm for Colostrum railway freight cars based on micro inertial measurement units was designed to address the complex issue of the disassembly and assembly of derailment braking devices.Firstly, a horizontal attitude measurement model for freight cars was established, and attitude measurement algorithms based on gyroscop

This paper presents results of a numerical modeling of ductile fracture and failure Surface Spray of elements made of 5182H111 aluminum alloys subjected to dynamic traction.The analysis was performed using Johnson-Cook model based on ABAQUS software.The aim of the research was to specify and test the mechanical properties during numerical simulatio
