Numerical solutions of quasi-stationary ring-spinning equations have been extensively investigated after the appearance of computer. However, mathematicians and engineers are more willing to obtain analytical solutions. This paper presents a technique for analytical solution of the dynamics of ring-spinning balloon. Artificial parameter is introduced in order to be used as an expanding parameter....
Enterprise Resource Planning (ERP) projects have often been found to be costly, complex, and risky to implement in enterprises. Therefore, understanding ERP implementation risks can help reduce the failure of ERP projects. The aim of this study was to explore two questions: (1) Do the six risk dimensions (planning & control, requirement, organization environment, user, team, and project complex)...
The reliability for measure and control system of a space environment simulator is analyzed in the paper to build the models. The paper systematically summarizes the state of measure and control system. The system structure and principles are introduced. According to requirement of environmental test, working procedures of the system are divided into the particular assignments. On the basis of reliability...
Poverty, a permanent problem in the society, is listed top-class global problem of social development by the United Nations. Grading the needy situation of impoverished families helps the government establish better policies, distribute resources more reasonably, and therefore provide aid more effectively. However, the traditional single-factor mode is not adequate, for poverty grade evaluation involves...
