Static footprint parameters have been used to quantify arch height with conflicting results. This could be caused by the inherent inaccuracy and variations of the methodology used. Since the foot is a dynamic structure that undergoes changes during a step, it is more desirable to capture and analyse the dynamic footprint at an instant during the gait ...

The investigation of contact ratio in mixed lubrication
Tribology International, 2006In order to describe the mixed lubrication in nano-scale which is constituted from dry friction, boundary lubrication, and thin film lubrication, a contact ratio between surfaces of a glass disk and a steel ball in a pure rolling process has been measured by the technique of Relative Optical Interference Intensity (ROII) with a resolution of 0.5 nm in ...

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
The mesh stiffness and contact ratio of gear drive are very important factors which have a great impact on the dynamic load. Contact ratio also affects the fluctuation and the mode of change of the mesh stiffness. In this research, a novel high contact ratio internal gear with a circular arc contact path is introduced.

Influence of contact tracing on sex ratios in gonorrhoea
Public Health, 1975The effect of contact tracing in reducing the sex ratio for cases of gonorrhoea has been considered using data provided annually by the Department of Health. A 10-year period was considered. By further classification of the figures into those cases that came directly to the clinics and those that were seen as a result of contact racing, the direct case

The AC/A Ratio and Convergence in Hypermetropia Corrected with Spectacles or Contact Lenses
American journal of optometry and physiological optic, 1982Abstract Some hypermetropes, when corrected with contact lenses, appear to have a much smaller AC/A ratio than when corrected with spectacle lenses. Ocular convergence measured with contact lenses is greater than that measured with spectacles. Studies were carried out to establish the cause of these effects. Theoretical considerations

Contacts on high aspect ratio 3D structures
Microelectronic Engineering, 2011We present a novel way for depositing material on the top surface of three-dimensional (3D) structures. This process supplies the possibility of applying a wide range of materials on the top of structures which are too high to be processed with conventional techniques. A planarization process or vertical sidewalls of the structures are not necessary.

Contact Ratio, Interference and Backlash
1987The meshing cycle of a tooth pair begins when the teeth first make contact, and ends when the contact is broken. If one gear is to drive the other in a continuous manner, there must clearly be at least one tooth pair in contact at all times. However, it is found that smooth operation is only possible when the contact at one tooth pair continues until ...

Measurements of Injection Ratio of Point Contacts on Germanium
Proceedings of the Physical Society. Section B, 1955Measurements are reported of injection ratio γ on various specimens of n-type germanium. γ was found to be insensitive to the nature of the contact material, to the contact thrust, and to the carrier concentration of the germanium over the limited range investigated.
