Based on the global features, the local information of different kinds of features is utilized. Both the global and the local features are combined together. Moreover, the multiple kernel learning method is adopted. The global features and each kind of local feature are respectively associated with a kernel, and all these kernels are added together with different weights to obtain a mixed kernel for nonlinear mapping. In the reproducing kernel Hilbert space, different kinds of emotional features can be easily classified. In the experiments, the popular Berlin dataset is used, and the optimal parameters of the global and the local kernels are determined by cross-validation. After computing using multiple kernel learning, the weights of all the kernels are obtained, which shows that the formant and intensity features play a key role in speech emotion recognition. The classification results show that the recognition rate is 78. 74% by using the global kernel, and it is 81.10% by using the proposed method, which demonstrates the effectiveness of the proposed method.展开更多

Based on image multi-feature fusion and support vector machine, a new method to identify flow regime in two-phase flow was presented. Firstly, gas-liquid two-phase flow images including bub- bly flow, plug flow, slug flow, stratified flow, wavy flow, annular flow and mist flow were captured by digital high speed video systems in the horizontal tube. The image moment invariants and gray level co-occurrence matrix texture features were extracted using image processing techniques. To improve the performance of a multiple classifier system, the rough sets theory was used for reducing the inessential factors. Furthermore, the support vector machine was trained by using these eigenvectors to reduce the dimension as flow regime samples, and the flow regime intelligent identification was realized. The test results showed that image features which were reduced with the rough sets theory could excellently reflect the difference between seven typical flow regimes, and successful training the support vector machine could quickly and accurately identify seven typical flow regimes of gas-liquid two-phase flow in the horizontal tube. Image multi-feature fusion method provided a new way to identify the gas-liquid two-phase flow, and achieved higher identification ability than that of single characteristic. The overall identification accuracy was 100%, and an estimate of the image processing time was 8 ms for online flow regime identification.展开更多

The MPSVMs are designed by mapping the output of standard support vector machines into a calibrated posterior probability by using a learned sigmoid function and then combining these learned binary-class probability SVMs. Two Bayes based methods for combining multiple MPSVMs are applied to improve the performance of classification. Our proposed methods are applied to fault diagnosis of a diesel engine. The experimental results show that the new methods can improve the accuracy and robustness of fault diagnosis.展开更多

In ＂neutrosophy＂ of renowed American professor F. Smarandache＇s terms, the interwar period was, in Romania, a ＂neutral＂ period. As mediating operators, professional journals reflected the atmosphere of relative tranquility and social peace. From the qualitative analysis of their media discourse, we can see three elements that： （1） the professional journals of Oltenia, as media tools for teachers, priests and folklore （folklorist）, or music enthusiasts （music lovers）, were loyal to their financial supporters; （2） although they served oblique and opposition interests, the communication professional operators have generally not emphasized, perpetuated or generated conflicts, disputes and misunderstandings; and （3） social attitudes promoted by professional magazines in Oltenia was a beneficial, objective one of better understanding and neutrality. The conclusion is that, despite the axiom that progress is generated by contradiction, it shows that professional journals in Oltenia, during 1920-1939, even in the absence of contradictions, namely under neutrality, there have been major advances.展开更多

This is the comprehensive implementation of urban and rural development to increase industrial agriculture, move the city to support the countryside, accelerate urbanization and narrow the gap between urban and rural areas. To solve the ＂three rural issues＂, the comprehensive construction ofa well-offsociety, has a very important strategic role to ease the contradiction of China＇s rural and urban ecnomic structure. In the process of building a new socialist countryside, the financial policy, as an important means ofmacroeconomic regulation and control, should play a leading role in solving the effective allocation ＆funds. Due to various factors affected by the current supply of rural financial market constraints, system defects and environmental constraints, there is a large gap between the level of the existing rural financial services and the requirements of the new rural construction which is to be improved urgently.展开更多

In recent years, the developing environment for the small and micro-sized enterprises in Hubei province has become increasingly severe, and the problems such as high management cost, high taxes and fees, financing difficulties, and labor shortages of the small and micro-sized enterprises have been more obvious, so that the further development, transformation, and upgrading of the small and micro-sized enterprises are severely restricted. In order to promote the development of the small and micro-sized enterprises, the developing environment for the small and micro-sized enterprises should be further optimized, the tax environment for supporting the development of the small and micro-sized enterprises should be well improved, the financing system should be promoted to be sound, the industrial structure should be actively adjusted, and also the development quality should be increased.展开更多
