摘要:Abstract(#br)A passive visible spectroscopic diagnostic which may measure the profiles of line emission and continuum radiation simultaneously is first installed on HL-2A tokamak. The line-integrated brightness profiles nearly covering the whole plasma cross section are meas...

摘要:Abstract(#br)The impact of a low frequency MHD mode crash on triggering the H-mode has been studied in detail on the HL-2A tokamak. The mode manifests fishbone characteristics with a precession frequency f ≈ 14 – 19 kHz . The abrupt mode crash evokes substantial energy relea...

摘要:Abstract(#br)Poloidal symmetric low frequency oscillations at the plasma edge were observed during the low-intermediate-high transitions on the HL-2A tokamak. The limit cycle oscillation (LCO) frequency gradually reduces from 3.0 kHz to 1.5 kHz approaching the H mode. Meanwhile a...

摘要:Abstract(#br)The array of autosomal recessive spastic ataxia of Charlevoix–Saguenay (ARSACS) has expanded worldwide after the first description in the Charlevoix–Saguenay region of Québec. Here, we report a Chinese ARSACS patient presenting progressive peripheral neurop...

摘要:Abstract(#br)Radial basis function (RBF) neural networks are investigated here for process fault diagnosis. The use of the output prediction error, between a neural network model and a non-linear dynamic process, as a residual for diagnosing actuator, component and sensor faults ...

摘要:Abstract(#br)A stable self-learning PID ( proportional + integral + derivative ) control scheme for multivariable nonlinear systems with unknown dynamics is proposed in this paper. The control scheme is based on a neural network (NN) model of the plant. The NN model is adapted by...

摘要:Abstract(#br)CN x /TiN y multilayers have been prepared by ion beam sputtering and analyzed by X-ray diffraction, transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray and X-ray photoemission spectroscopy. The structure analyses shows ...

摘要:Abstract(#br)Implementation of a neural network model-based predictive control scheme to a laboratory-scaled multivariable chemical reactor is described in this paper. Three variables are controlled in the reactor—temperature, pH and dissolved oxygen. The reactor exhibits co...

摘要:Abstract(#br)An adaptive neural network model-based fault tolerant control approach for unknown non-linear multi-variable dynamic systems is proposed. A multi-layer Perceptron network is used as the process model and is adapted on-line using the extended Kalman filter to learn ch...

摘要:Abstract(#br)In modelling non-linear systems using neural networks (NN), a commonly used method for the selection of network inputs, or to determine system order and time-delay, is to try different combinations of the system input–output data and choose the best one, giving ...
