As improving fuel economy and performance through weight reduction in vehicles are recognized as important tasks, the defense industry is researching ways to reduce the weight of armor plates for combat vehicles and increase bulletproof performance and durability.Most armor plates in combat vehicles are manufactured using weld joints.High-hardness
Purpose: In this study, a mixed-integer programming model is developed to minimize the total lateness and total completion time of the jobs in an automotive company.In order to respond rapidly to the continuous customer demand through the production, the work schedule of engineers in the research and development department is considered flexibly.Me
This paper proposes a three-dimensional lever-type inertial amplification metamaterial for the mitigation of low-frequency vibration.This metamaterial was developed as a small, stiff, and single-phase structure that can inhibit the transmission of vibration in a certain frequency range below 100 Hz.An analytical model was developed to derive analyt
Attention contains three functional network subcomponents of alerting, orienting, and executive control.The attention network test (ANT) is usually used to measure the efficiency of three attention subcomponents.Previous researches have focused on examining the unimodal attention with visual or auditory ANT paradigms.However, it is still unclear ho
