Accurate on-line measurement of ball mill load (ML) affects production capacity and energy efficiency of the grinding process. An on-line soft sensor method based on recursive principal component analysis (RPCA) and on-line least square support vector regression (LSSVR) was proposed in this paper. At first, spectral principal components (PCs) at low, medium and high frequency bands of the vibration...
This paper proposed a new hybrid forecasting model for the prediction of ozone concentrations in semi-arid area. It is based on chaotic, particle swarm optimization algorithm (CPSO) and back propagation (BP) neural network, called CPSO-BP neural network. The results show that the proposed hybrid model is superior to both the BP neural network and the regression model being tested. The hybrid model...
Combining neural networks and fuzzy systems is a great tool for modeling nonlinear systems. Few researches have presented useful or practical results on the case of lack of data, which does not provide necessary information for training the model. In this paper, we proposed a new modeling idea based on nonparametric regression, which provide us prior information for constructing the fuzzy system....
It is difficult to establish a black-box model for sparse data, because not enough data can be applied for training. This paper presents a novel identification approach using multiple fuzzy neural networks. It focuses on structure and parameters uncertainty which have been widely explored in the literature. Firstly, the sparse data are used within a fixed time interval to generate model structure...
The purpose of this paper was to find some feature pattern which may be used in diagnosis of blood stasis syndrome (BSS, a unique concept of traditional Chinese medicine) with myocardial ischemia. After establishing an animal model of Chinese experimental miniature swine, 7 indicators in plasma, e.g. troponin T (cTNT), heat shock protein 27 (HSP27), cytochrome C (Cyt C), endothelin-1 (ET-1), calcitonin...
Steel string strain gauges are pre-embedded in ten pieces of 20m-span low-height reactive powder concrete(RPC) T-beam to test the changing law of early shrinkage along the height of T-beam's section. According to this law, self-restraint stress which comes out of uneven shrinkage of RPC, and easy cracking dangerous areas which are caused by self-restraint stress, are both analyzed. Then S.Miyazawa...
