After researching the discrete standard quantity system dynamic error separation technique,two error correction methods based on genetic algorithm and neural network mixed modeling technique are established.
lowing an analysis of different kinds of commonly-used centering correction methods,the paper makes a discussion of the feasibility and superiority in applying gyroscopic orientation for correction of centering in GPS surveying.
本文分析了几种常用的归心改正方法，探讨了在 G P S定位测量中应用陀螺定向进行归心改正的可行性和优越性。
Based on an analysis of the major factors affecting the quality of data obtained in aeroelectromagneticsurvey, this paper has put forward zero horizontal drift correction methods such as field value standardization andphase check and correction, studied and developed a suite of techniques suited to data - processing and graphical representation for aeroelectromagnetic method.
In order to weaken the influence of atmosphere refraction on elevation surveying in dam three-dimension automatic surveying system, on the basic of characteristic and relativity of atmosphere refraction in small scope of highland, the gray model of refraction coefficients and correction methods are studied. The problem of refraction correction of unilateral triangulation in dam safety monitoring is efficiently solved.
This paper introduces the technology for the reinforcement of the existing railways,as well as the construction methods,technical measures,deviation prevention methods and deviation correction methods taken during the jacking of the large-span oblique-crossing frame-shaped culvert.
The success of these automatic correction methods depends on the fundamental principles of the recording situation, the actual characteristic of the distorting noise and the parameter justification by the operator.
Using the theory of Subspace Correction Methods robustness is proved of both the multiplicative and additive variant applied to anisotropic problems in an arbitrary number of space dimensions.
Implementation of defect correction methods for stiff differential equations
New high resistivity CdZnTe material, new contact technologies, new detector structures, new electronic correction methods have opened the field of nuclear and x-ray imaging for industrial and medical applications.
Intracavity correction methods have been considered, which shows that the proposed gradient method enables one to find the flexible-mirror profile with allowance for diffraction effects.
