The Yugur nationality is one of the ethnic groups with a small population in China, and the Yugur nationality has its own language. In the course of development, the Yugur language is divided into two types: Eastern Yugur and Western Yugur. The native language has been lost. Yugur language currently has a very small population and is an endangered language, and the special attributes displayed in the evolution of the language make Yugur language research of great value. This article will start from the design of the voice database, with the purpose of protecting and preserving the existing Yugur language, taking the western Yugur language voice database design as an example, introduce the design of the western Yugur language voice database, and propose the western Yugur language signals and parameters Set standards.

In artificial intelligence research, prosodic and pitch features are the focus of singing intelligent speech synthesis. Pitch features are usually studied by extracting fundamental frequencies. In the process of folk song singing, many special vocal skills are used, mainly related to the mode of vocal fold vibration. Using singing voice signals and parameters to study singing pitch and vocal types can better obtain the pitch and prosodic characteristics of singing. This experiment mainly takes Ewenki folk songs as the research object, analyzes singing voice signals and parameters, so as to provide reference for singing voice synthesis. The Ewenki are one of China's ethnic groups with a small population. The Ewenki folk songs are sung in the Ewenki language, which retains many features of ancient folk songs and singing pronunciation characteristics, especially in the vocal vocalization of the singing voice. The article takes the typical traditional folk song of Ewenki, "Molie Girl", as the object of study. By collecting the singing voice and voice signals of a professional and a non-professional singers, extracted the parameters of fundamental frequency, open quotient and speed quotient. After statistical analysis of the parameters, the overall voice characteristics of the professional and non-professional singers during the singing process and the differences in the voice parameters of the trailing part of the voice were obtained. The analysis revealed both professional and non-professional singers were able to express the artistic characteristics of traditional folk songs, with different vocal styles and singing techniques. The experimental voice acoustic parameters and results can be used as a reference for the synthesis of traditional folk songs and as a method for the teaching of traditional folk songs.

Most drivers often make route choices according to their preferences in our real life, and they have different requirements for different path attributes. In this paper, the problem for optimal path selection with driver's preference is studied and path selection algorithm based on Grey Incidence Decision is put forward. Firstly, a path selection index system was constructed in order to reflect the driver's preference. Analytic Hierarchy Process was used to calculate the driver's preference coefficient for the path. Secondly, since the process of path selection in Route Guidance System is complex and contains a lot of “grey” information, the method based on Grey Incidence Decision was proposed to sort paths. Finally, an actual network was used to simulate, the combination of Analytic Hierarchy Process and Grey Incidence Decision searched the optimal path reflecting driver's preferences. The simulation results show that the proposed path selection algorithm has good feasibility and applicability.

With rough set and software tools-ROSETTA, the possibility of adopting series timing analysis in the process industry has been able to show in this article. There is some shortcoming for traditional time series analysis adopted in data mining, such as the window method has the limitation on the length of time series which can be analyzed. Because of limitations mentioned above, the direct apply of traditional methods in industrial processes data mining has become unsuitable. The method introduced in this paper adopted a method similar to which operator monitor the actual production process, so which it overcome the limitations of traditional methods.

Super fine cement is a kind of smashed ordinary G grade oil well cement. Though its chemical property isn't changed, its physical properties are improved, which brings obvious advantage in recementing operations such as casing leakage repairing, out-casing channel plugging and high water cut zone plugging etc. Since super fine cement firstly being produced in XianHe Oil Production Plant in 1994, super fine cement plugging technology has been developed in many aspects including super fine cement series, plugging method, result examination method and matching tools. Up to now, it has become a mature technology and gained good results in developing the potentiality of remaining oil in old oilfields.

This paper takes the love songs of the Ewenki traditional folk songs as the research object, extracts the acoustic parameters of five representative folk songs, including the duration, intensity and formant of the speech, as well as the fundamental frequency, open quotient and speed quotient of the voice signal. Finally, the acoustic characteristics of the speech and voice are obtained. The findings of the study can provide a new method to the study of speech and singing acoustics, and also provide parameters for reference and identification of singing speech and synthesis.
