In order to solve the problem of garbage treatment effectively, a control method is proposed based on Takagi-Sugeno (T-S) fuzzy neural network model after analyzing the characteristics of garbage incinerators system and the main factors affecting combustion. A T-S fuzzy neural network model for garbage incinerators control is established which utilizes bp learning algorithm for data training. Then a simulation research is carried out to verify the feasibility and superiority. Results show that the T-S fuzzy neural network control can well track the input in a relative short time. The contrast analysis with conventional PID control and fuzzy control is done to show a better performance under the fuzzy neural network control. The fuzzy neural network control method can adapt to the complex garbage incineration process, which makes it high application value.

An intelligent pattern recognition used artificial neural networks is presented in this paper to meet the requirement of controlling stripe shape in cold rolling. The cold-rolled products are characterize into several types based on its irregularity, 'left wave', 'right wave', 'center buckle', 'edge wave', 'W-type', and 'M-type'. The developed identification algorithm calculates for each type of irregular strip shape using neural network and experiment data. The work is studied by taking a double-stand reversing cold rolling mill as example. The method improves the speed and the accuracy of strip shape identification.

This paper addresses the application of neural network to air-cooling condenser faults diagnosis. For traditional Back Propagation (bp) neural network algorithm, the learning rate selection is depended on experience and trial. In this paper, an improved bp neural network algorithm with self adaptive learning rate is proposed using the fundamental equation. Unlike existing algorithm, self adaptive learning rate depends on only network topology, training samples, average quadratic error and error curve surface gradient but not artificial selection. The train results show iteration times is less than that of traditional algorithm with constant learning rate and it is a feasible method to diagnose air-cooling condenser faults.

Presently, electromagnetic field numerical value analysis methods such as finite difference time-domain (FDTD) method are generally used to calculate the DGS, although these methods are accurate, they are also computationally expensive. In this paper, a neural network model of a novel defected ground structure is established. Since the neural network model has the advantages of great precision and effectiveness, the developed design model can be used to take the place of the FDTD method of the DGS, being a kind of aid tool of circuit design. The neural network models of two different non-periodic DGS have been developed, at the same time the circuit of the according DGS is designed and manufactured. The result of computer simulation and product measurements are obtained to demonstrate the effectiveness of the method.

The Luby Transform (LT) codes have been suggested as an efficient solution for multimedia communications over erasure packet network, and provide equal error protection (EEP) for all input symbols. However, for the progressive image transmission, the significant source bits are generally located ahead of the bit streams of the encoder output, which are more important for the reconstruction of the image. Therefore, the LT codes based on EEP (EEP-LT) scheme is not suitable for the progressive image transmission. In the paper, based on the LT codes, a novel unequal error protection (UEP) scheme is proposed for image transmission over multiple input multiple output (MIMO) channels, which is named UEP-LT scheme. Simulation results confirm the efficiency of the proposed scheme.

Probabilistic Neural Network (PNN) overcame the shortcomings of entrapment in local optimum, slow convergence rate which was in bp algorithm. With enough training samples, PNN obtained the optimal result of Bayesian rules. Because of the fast training rate, the training samples can be added into PNN at any time. So, PNN is fit to diagnose the fault of power transformer and has auto-adaptability. In order to improve the classification accuracy, the conception of combination is introduced into PNN. The fault diagnosis of power transformer is consisted of 4 Probability neural networks in this paper. PNN1 is used to classify the normal and fault. PNN2 is used to classify the heat fault and partial discharge (PD) fault. PNN3 is used to classify the general overheating fault and severe overheating fault. PNN4 is used to classify the partial discharge fault, and energy sparking or arcing fault. The example shows that the effect of combinatorial PNN is a good classifier in the fault diagnosis of power transformer. The combinatorial PNN has better diagnosis accuracy than bpNN and FUZZY algorithm.
