This paper proposes a run-to-run(RtR) fault detection approach for general semiconductor manufacturing processes. In this paper, a data-based model, auto-regressive with exogenous inputs (ARX) model, will be introduced as an alternative of a mechanical model for a semiconductor manufacturing process. In this model a recursive least-squares (RLS) algorithm is proposed to identify the on-line parameter...
In supply chain, the ordering strategy is one of the main reasons leading to Bullwhip Effect which can induce inventory's fluctuations or excessive inventory. In this paper, we set up a simulation model on the retailer' s demand-driven supply chain by virtue of system dynamics, in which we compare the inventory's behavior mode based on different ordering strategy, whose simulation results testify...
In this paper, we proposed a new data fusion method to infer gene regulatory networks based on differential equations model. After testing on several simulation and real data sets, and comparing with three other kinds of single fusion methods, the results show that our method is effective and better than other 3 fusion methods in inferring networks.
This study attempted to find the adsorption law of fly ash to COD in domestic sewerage. After the elementary characterization of fly ash was described, the influence of contact time, sorbent concentration, and different pretreatment ways of fly ash, initial COD concentration and temperature on the adsorption process was investigated. Results showed adsorption equilibrium attained within 120 min time...
Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnacepsilas very large power input ratings. In order to propose solutions to minimize the adverse effects, developing an accurate electric arc model has a much needed task. Hence, a new time domain electric arc model is developed on the basis of the conservation of energy,...
