Curvature reflects the size of bending degree of curve. In this paper, we put forward a new relational degree model based on curvature of the two series. The new model satisfies the parallel property and uniform property. It is consistent with the actual situation by comparison to the existing relational models. At the end, we give a case in order to validate the new model.
This paper analyzes main factors that affect yield rates and risks of short-term financing bonds in Huainan Mining Group by KMV model and SHIBOR standard. The result indicates a smaller credit risk, a potential increase of the interest risk and a smaller liquidity risk as well. In addition, other risks like safety risk, guarantee risk and environmental protection policy risk are also significant factors...
In the process of coal mine construction, it is significant that how to identify the risk factors and to take measures to prevent the occurrence of safety accidents for the mine investment unit to speed up the construction of the new mines and exploit the coal energy rationally. With the ability of structural equation model that processes the variables and their relationship, this article applied...
Air flow character and gas mathematical mode of heading laneway in coalmine is researched in detail to tackle with normal ventilation and gas discharging problem. Combining with ventilation requirements and safety regulation in coalmine, control strategy which aims at both safety and energy saving is established at length. Moreover, conventional double fuzzy control model is found to carry out two...
Based on the System Dynamics theory and the causality of the factors influencing competency of mine special operators, this paper established a dynamic simulation model of Training function on the Influencing Factors of mine special operators' Competency. The studies showed, under the same training inputs, coping capacity, sense of security responsibility, and self-management skills have more visible...
In this paper, finite element analysis has been applied on the Phi2.8 mtimes5.75+2.25 m of southern Africa that has been contracted by CBMI Construction Co Ltd. Different contact finite element model as manholes in different position of the twelve clock points are built by using ANSYS parametric design language (APDL). Stress and deformation under the actual condition were presented by calculating,...
The research of the impact of safety regulation on the operation of enterprise is difficult, because the acquirement of data is different and research cycles are too long. To solve these issues, the paper imports the idea of multi-agent model to build a virtual platform using computer technology, and then research these issues with this platform. This paper proposes a multi-agent model which contains...
