Research on Prediction Method of Transmission Accuracy of Harmonic Drive
Volume 10: 2019 International Power Transmission and Gearing Conference, 2019Abstract Harmonic drive is an indispensable device for robotic joint, and transmission accuracy of harmonic drive is one of its most important performance indexes. Due to the unsystematic research on the accuracy of harmonic drive, the accuracy consistency of harmonic drive is poor, and the prediction accuracy is seriously insufficient ...

Registration accuracy of 153Gd transmission images of the brain
European Journal of Nuclear Medicine and Molecular Imaging, 2004The aim of the study was to determine the accuracy of non-rigid nine-parameter image registrations based on 153Gd transmission computed tomography (TCT) images as compared with those based on 99mTc-ethyl cysteinate dimer (ECD) images and to assess whether normalised mutual information (NMI) or count difference (CD) should be used.TCT and ECD data were ...

Accuracy of paediatric echocardiographic transmission via telemedicine
Journal of Telemedicine and Telecare, 2006We evaluated the accuracy of realtime echocardiography studies conducted via telemedicine (at 384 kbit/s) and prerecorded video studies, by comparing the results with subsequent in-person echocardiography examination performed at follow-up. Between January 2002 and December 2004, there were 769 paediatric echo studies of patients aged one day to 19 ...

Accuracy of Evaluation of Speech Transmission Index with Formant-Modulation Method
Radioelectronics and Communications Systems, 2023Unlike the known modulation method, the formant-modulation method for the evaluation of speech intelligibility allows the evaluation of not only the speech transmission index but also the articulation index. This paper presents the results of a study of the accuracy of speech transmission index evaluation using the full and rapid variants of the ...

Accuracy issues in microwave characterization of graphene transmission lines
2014 IEEE 2nd International Symposium on Telecommunication Technologies (ISTT), 2014In this paper, we compare several calibration methods available for on-wafer microwave measurements conducted on transmission lines made of graphene. Multi-layered graphene films were grown on Si wafers coated with SiO 2 and Ni using chemical vapor deposition.

On the accuracy of Friis' transmission formula at short range
2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017This paper presents a numerical investigation on the accuracy of Friis' transmission formula for short distances between the transmitting and receiving antennas. It addresses the accuracy of the formula around the far-field distance where effects due to multiple reflections may be of significance.
