This paper presents a novel nonlinear velocity estimation method for robotic joints based on inverse hyperbolic sine tracing differential algorithm. Unlike the conventional methods that using the motor-side position measurements to obtain the joint velocity, this paper addresses the problem of joint velocity estimation that using the link-side absolute encoder data, so that the kinematic error caused...
Aiming at the fast processing demands of large batches of UAV data processing in Photogrammetry, this paper studies the GPU acceleration matching method guided by Position and Orientation System (POS) and combined with RANSAC method for excluding mismatching points. Experiments are carried out according to the Songshan Calibration Field's Mapping Project. Firstly, three groups of stereo image pairs...
Experimental investigations on turbulent heat transfer of carbon dioxide in a helically coiled tube were performed under constant wall heat flux conditions. A computational program was compiled in a helical coordinate system to calculate the inner wall temperatures based on the directly measured outer wall temperatures by thermocouples. It was found that the wall temperatures increased with the increasing...
The article will provide an idea to investors for review and investment decision-making without errors through the analysis on the existing hydropower projects through the use of funds and financing plan, sale estimates, the total cost, current assets, loan and repayment term, profits and distribution, solvency, profits ability and the financial sensitivity.
Internet of things (IOT) based on EPC system is a revolutionary new technology of modern logistics management. IOT can obtain intelligent recognition, location, tracking, monitoring, management and its application in logistics management can achieve real-time tracking of goods, improvement of information transparency and visual management, thus can highly optimize logistics management. Presently in...
