This paper focuses on usage intention of the e-commerce based on ATM model. After empirical analysis, the following conclusions were made: Customer usage attitude has a significant positive impact on customer usage intension; customer perceived usefulness, perceived ease of use and perceived risk would significantly affect usage attitude. At the end, this paper proposes related suggestion about e-commerce.
In this paper, we investigate the permanence of a class of Holling III-Tanner predator-prey diffusion system with stocking rate and time delay, the existence positive periodic solution by using Comparability Theorem, Coincidence Degree Theory. We obtain the sufficient conditions which guarantee permanent of the system and existence of the positive periodic solution of the periodic system. Some new...
The new method of one-factor analysis of variance for medical statistical data with binomial distribution is studied in this paper. The total probability variation of the control groups is decomposed into sample probability variation and probability variation between samples in control groups, the statistical analysis will be done to the data with binomial distribution by using one-factor analysis...
The design conditions of traditional terminal sliding surface for second order system are raised, and proved the singular phenomenon is inevitable when use the traditional terminal sliding mode surface. A new nonsingular terminal sliding mode surface is proposed for second order nonlinear dynamic system with external disturbance. The time of reaching this kind of TSM from any initial system state...
A new reaching law of sliding mode control is proposed. It is an efficient technique to reduce the chattering and to guarantee a good robustness of systems by using time-variable boundary layer. The design approach is much simpler than other approaches of time-variable boundary layer reaching law. The simulation results show that the novel control strategy is effective and feasible.
