Use of cluster analysis method to increase the efficiency and accuracy of radar data processing
The article presents a range of solutions to improve the efficiency and accuracy of multiradar data processing using cluster analysis method. For this purpose commend to use cluster analysis method, based on which authors made an improvement for the classical abnormal measurement rejection algorithm and consider a possibility to implement a multithread processing of radar data.
Modeling Technological Support the Process of Grinding Abrasive About
Consider the impact of technological regimes polishing surface finish and establish the optimal conditions for grinding and abrasive wheels revision in view of their period of stability.
Evaluation of Integrated Self-adjusting Equipment Errors Impact on Machined Cylindrical Surfaces Accuracy
The paper deals with the analytic model suitable to evaluate the errors impact on the output surface accuracy in the machining process using the integral self-adjusting machine tool equipment. This model is based on the variation simulation method of machines precision calculation. The impact evaluation of accessories errors of force action from the cutting process as well as clamping is developed. This evaluation substantially considers the output accuracy of the machined cylindrical surfaces of the console fixed parts.
Precision of digital leveling with additional movements of the rails
The investigation to assess the impact of change in position heel staffs on the accuracy of determining the excess on the station at digital leveling was performed. It is proved if the accuracy of determining the changes in position heel staffs substantially higher than accurate reading rod accuracy leveling does not change, so these changes can serve only to control the leveling on the station.
Accuracy of determining the position of object points in ground digital survey
The analysis of influence the errors of exterior orientation elements on the coordinates when digital external survey.
The accuracy of determination of boundary position and areas of land parcels for inventory of urban land
The results of studies to assess the accuracy of determining the area of land in different ways.
Research of GPS-observations accuracy with part horizon closure
Possibility of the use of GPS-observations with the partly closed horizon is investigated. Accuracy of baseline vector determination in dependence of elevation mask and period of satellite observations is analyzed.
