The purpose of this paper is to present some issues that arise when applying a traditional continuous-time approach to system identification. In particular, we consider the bias that is introduced into the continuous-time model through the use of sampled data which is filtered to recover the derivative of the continuous time signals. We find that this error has two constituent components, one being...
Although the grey forecasting model has been successfully adopted in quality prediction control field and demonstrated to have promising results, its performance still could be further improved. For this purpose, a grey dynamic model group based on GM(1, 1) model to solve this problem is presented by founding a series of grey models. In this paper, firstly, adopting GM (1, 1) model based on grey forecasting...
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...
The adsorption and desorption properties of beta-cyclodextrin polymer (beta-CDP) for 4-cresol were investigated. Studies concerning the effects of pH, contact time and initial 4-cresol concentration were presented and discussed. Results of batch experiments showed that this adsorbent exhibited some sorption capacities toward 4-cresol. It was found that kinetics followed a Ho and McKay equation and...
