Abstract: Focusing on the speech recognition function of Automatic Speech Translation System, applying the figures and data collected from tests, and testing the deduced formula, the thesis mainly compares the computer-aided speech recognition with the pure manual one. As shown by the results, during the whole process of speech recognition, the computer-aided one consumes less time than the pure manual one does, and this time remains to be 2 seconds. It can be said that the technological feature, “little time-consuming”, ensures the system’s superiority of spreading information in unit time.

Abstract: In order to make training for the substation operation and maintenance personnel professional skills more effectivethis paper has designed a three-dimensional substation simulation training system based on Unity3d.In this paper,a variety of virtual scenes of the substation are studied,designed a 3Dsimulation training system of substation based on operation and maintenance personnel behavior. Framework of system comprises two-dimensional mathematical modeling, 3D modeling, development and release of platform.

Find its shortcomingsand propose an improved method for the deficiencies, and establish the neural network softwarereliability of the new model.Through MATLAB simulation tools forexamples of simulation, confirmed the new model year with the traditional modelof high-precision, the characteristics of generalization stronger.

Abstract: The issue of WDM network traffic grooming has been a hot in the field of research. The implementation of traffic grooming technology can improve the utilization of wavelength channels, reducing the link delay and the blocking rate of the network, which to improve network resource utilization and optimize network performance. This article mainly studies all-optical network routing algorithm utilizing WDM technology to achieve the dynamic traffic grooming and propose a optimization grooming policy -HaffmanGroom (M) algorithms which based on SONET / WDM ring network. The most important feature of this algorithm is that the SONET / WDM ring network of multiple multicast request packet , with a minimum weight of the light path priority selection method, the flow of requests each group effectively optimize ease . The algorithm takes into account the impact of the link request factor and link hops to optimize the link selection. The simulation results show that under the conditions of factors and the number of hop a request fully consider the impact of these two factors to the link, and can achieve optimal link with the smallest weights for effective data transmission, improving resource utilization, reducing blocking rate in order to achieve the purpose of optimizing network performance.

Abstract: This paper briefly describes the most important resources in the area of information resources organization and retrieval (RDA) summary of advantages and application of, and from the perspective of discusses the difficulty of understanding the RDA. The author suggests that catalogers should take countermeasures under the new circumstances.

Abstract: data information management has thoroughly changed the traditional mode of data management, whose real ability is not only presented on a more efficient work way, but also on the creation of a new work approach, which is the core content of department work flow reorganization, and also the embodiment of the ultimate goal of department workflow reorganization. With the continuous development of enterprise information, the establishment shall be constantly perfected of data management information system.

Abstract: In this paper, we study the Schur decomposition for unitary symmetric matrices: The formula for the Schur decomposition is obtained, and the relationship of the unitary symmetric matrix with mother matrix is also obtained.

Abstract: In this paper, we propose a weighted quantile regression method for partially linear models with missing response at random. The proposed estimation method can give an efficient estimator for parametric components, and can attenuate the effect of missing responses. Some simulations are carried out to assess the performance of the proposed estimation method, and simulation results indicate that the proposed method is workable.
