With the rapidly development of science and technology. The single navigation system for positioning and orientating is not adequate for the requirement of navigation, position, and orientation in the field of military and civil. The higher precision and cheaply cost of integrated navigation system are gradually applied for every field. Therefore, the combination of GPS and INS constitute the integrated navigation system becoming a developmental direction. This thesis discusses the technology problem and calculation methods of GPS/GLONASS/INS integrated navigation system. Firstly, it summarizes the merit and demerit of GPS and INS navigation system respectively. Putting forward the GPS/GLONASS/INS integrated navigation system based on information fusion technology. Also, a new method of GPS/GLONASS/INS integrated navigation system for quick positioning and orientating is presented, on the basis of which the scheme and the principles are given. Then a multi-sensor information fusion algorithm based on federal kalman filter is analyzed in detail. Finally, the {3. simulation is given. The results show that federal kalman filter can deal with information fusion for the GPS/GLONASS/INS integrated system. Efficiently improving the accuracy and the reliability of the navigation system. It is the best way for seeking the navigation parameter and lead to the GPS/GLONASS/INS integrated system acquiring superior performance.

The bowtie effect refers to geometry distortions for the moderate resolution imaging spectrum-radiometer （MODIS） level 1B （L1 B） data. Till now, to eliminate the bowtie effect, numerous methods are proposed. However, most of them have limitations in computation efficiency. Through a comparative study of existing methods, this article puts forward a fast method to eliminate the bowtie effect using the ephemeris data. In this method, the rough positions of overlapping data are first detected. Because of the influence caused by the instrarnent characters and the earth＇s curvature, the positions of overlapping data need to be rectified to obtain more precise results. The optimal rectification method used in this article is selected by comparing three methods. By using the optimal method, the rectified MODIS data can be obtained. The experiments demonstrate that the bowtie effect can be eliminated in less than 1 s. In contrast, other traditional methods spend at least 3.s, thus the proposed method is faster and more effective.

The key ingredient for promoting software reuse in a repository base integrated development environment, is to provide support for the software developer who wants to search the repository to locate and retrieve suitable software components for reuse. This paper presents that reusable software components form a base to provide a flexible representation of component adaptability to any repository with a specific classification. As an alternative, it proposes to automatically identify and convert the component source code with all its information into a standard form, so that components can be transferred from one type of library to another.

An experiment was conducted to study the effect of high dietary copper on the growth performance,NPY concentration and NPY mRNA expression level in hypothalamus of ***-five crossbred pigs were randomly assigned to three groups of fifteen pigs with five replicates of three pigs each. Pigs were allotted to dietary copper(Cu) treatments that contained 10(as control),125 and 250 mg/kg Cu as CuSO in the diet *** animal performance was determined at the end of the experiment and five pigs selected randomly from each group were slaughtered,hypothalamus was collected for determination of NPY concentration and NPY mRNA expression level by relative quantitative RT-PCR. The result was as following:compared with control,ADG,ADFI,were increased and F:G was decreased in pigs fed the diets with 125 and 250 mg/kg Cu,(P<0.05),but there was no statistic difference in growth performance between 125 and 250mg/kg ***,Pigs fed the diets with 125 and 250mg/kg Cu had higher NPY concentration and NPY mRNA expression level in hypothalamuses than those of control. These data indicated that 125 and 250 mg/kg Cu gave a similar response in growth performance,and high dietary copper could enhance NPY concentration and NPY mRNA expression level in hypothalamus of *** dietary copper increases feed intake and promotes growth performance may through enhancing NPY concentration and NPY mRNA expression level in hypothalamus of pigs.
