The empirical correlation system serves as a crucial tool for unveiling the linear interconnections between two variables.Its significance lies in providing a prominent approach to depict a straightforward relationship without explicitly indicating a causal link between the sets involved.In the current research, an innovative concept of correlation
In order to study the effect of wheel harmonic wear on train operation safety, the Nail Hardener simulation model of train-track-subgrade coupling system which considered rail and track plate vibration was established.According to the harmonic order of the first-order, sixthorder and eleventh-order in the wave depth of 0.1 mm and 0.3 mm, the wheel-
Nature-based tourism can generate important revenue to support conservation of biodiversity.However, constant exposure to tourists and subsequent chronic activation of stress responses can produce pathological effects, including impaired cognition, growth, reproduction, and immunity in the same animals we are interested in protecting.Utilizing feca
Manpower and personnel is an important part of the support resources which can seriously influence the efficiency of the equipment support system.In order to effectively estimate, balance and optimize the support ability of logistical support staff, the Main Tub Bearing paper created a hierarchical logistical staff support ability evaluating parame
