Design on Transmission Accuracy Testing System of Actuator
Advanced Materials Research, 2014Actuator is the main executive mechanism for the attitude control of aircraft in the aerospace industry and aviation field. With the further development of technology, higher quality of product research and detection has been required. According to the test requirements, the actuator nonlinear parameter testing system is designed to realise the ...

On the accuracy of the transmission line model of the folded dipole
IEEE Transactions on Antennas and Propagation, 1980A folded dipole is basically an unbalanced transmission line which radiates as a result of its unbalanced condition. It is known that the folded dipole may be analyzed by considering its current to be composed of two distinct modes, namely, a transmission line mode and an antenna mode.

Accuracy and stability of finite element schemes for the duct transmission problem
7th Aeroacoustics Conference, 1981An investigation is conducted regarding the feasibility of approaches for improving the efficiency and stability of existing finite element method (FEM) schemes, taking into account both analytical and numerical studies. Of the four schemes considered for the 'steady' problem, the Hermitian Galerkin formulation appears to be the most efficient and ...

Accuracy of the multilayer Born approximation in transmission and reflection
Journal of the Optical Society of America AThe simulation of light scattering by heterogeneous dielectric objects that are large compared to the wavelength is the bottleneck of many quantitative imaging techniques. The rigorous Maxwell equation solvers are slow and have high memory requirements; several approximate models have been developed to address this issue.

Accuracy of prospective space–time surveillance in detecting tuberculosis transmission
Spatial and Spatio-temporal Epidemiology, 2014To improve detection of tuberculosis transmission, public health can supplement contact tracing with space-time surveillance. However, investigation of space-time clusters not due to transmission (false alarms), may lead to costly, unnecessary interventions.

Accuracy of small encoders for gear transmission errors
Proceedings of the I MECH E Part C Journal of Mechanical Engineering Scienc, 2001For noise investigations and development work or precision production control of gear drives there are major advantages to using small encoders for transmission error measurement in situ owing to reduced size, inertias and cost. As there was uncertainty concerning the accuracies that would be obtained in practice, a small encoder was calibrated and ...

On the accuracy of the transmission line theory for the insulated linear antenna
IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003An insulated linear antenna consists of a metallic, cylindrical conductor covered by a concentric sheath of dielectric with relative permittivity /spl epsiv//sub ri/. Insulated antennas are almost always used in an ambient medium, such as soil, seawater, or biological tissue, whose electrical properties are quite different from those of the insulation;

System Optimization for Improved Accuracy in Transcutaneous Signal and Power Transmission
IEEE Transactions on Biomedical Engineering, 1984A stable transcutaneous transmission of power and signal via two coupled coils with minimized dependence on the relative spacing of external and implanted coil is possible by employing "critical coupling" between implanted and external circuits.

Accuracy of approximate transmission line formulas for overhead wires
IEEE Transactions on Electromagnetic Compatibility, 1989Errors resulting from two approximations of the transmission line parameters of overhead wires are determined. Sunde's simple approximation (1968) is found to be more accurate than the Hankel function approximation. >

Diagnostic accuracy of a teleradiology image transmission system.
M.D. computing : computers in medical practice, 1989Teleradiology is the remote interpretation of digitized radiographic images by physicians. The images are usually transmitted over telephone lines, but satellite communication has also been used. The interpretability of the transmitted image is an important factor in the operation and use of teleradiology systems.
