STUDY ON OPTIMUM ANALYSIS METHOD OF UAV-SfM/MVS SURVEY AND TOPOGRAPHIC CHANGE CHARACTERISTICS OF GRABEL BEACH

The article analysis comprehensively the features of time change and spatial variation on each class of land use about Baolan-Lanqing-Qingzang urban belt, using EXCEL based on the data of land change from 1991 to 2009. It reveals the amplitude, velocity, regional difference and the distribution of spatial variation on principal class of land use in the study district. Meanwhile, we actually analysis the social economic factors by using factor analysis method in SPSS, which reflect population economy and urban industrial structure are the principal components to influence on the land use about Baolan-Lanqing-Qingzang urban belt.

Maximum Separation

AbstractA series of simulated microstructures containing nanometer-scale precipitates was created with an atom probe simulator. These data were then analyzed with the proximity histogram and the maximum separation method to determine the influence of the particular analysis method. For simulated 2-nm-radius spherical precipitates, the optimized voxel size and delocalization were found to be 0.5-0.6 nm and 1.0-1.5 nm, respectively. Under optimum analysis parameters, the voxelization/delocalization process only slightly degrades the interface width determined from the proximity histogram to ˜0.15±0.04 nm.

Crawler Crane

A system simulation model is established by multidisciplinary simulation software Amesim. This model is on account of travel system of a certain hydraulic crawler crane, mainly on selector valve and load sensing pump. Based on this model simulation and dynamic analysis is carried out, then output volume change characteristics of load sensing pump along with load changes is got. Contrasting the simulation result and experiment result, correspondence is very good， which indicate that this model and related parameters are in accordance with real system. A simulation analysis method used to analysis changes of load sensing pump along with load changes is provided.
