Natural gaits of the non-pathological flat foot and high-arched foot
Yifang Fan, Yubo Fan, Zhiyu Li +2
There has been a controversy as to whether or not the non-pathological flat foot and high-arched foot have an effect on human walking activities. The 3D foot scanning system was em…
Bone in vivo: Surface mapping technique
Yifang Fan, Yubo Fan, Zhiyu Lin +1
Bone surface mapping technique is proposed on the bases of two kinds of uniqueness of bone in vivo, (i) magnitude of the principal moments of inertia, (ii) the direction cosines of…
Foot Bone in Vivo: Its Center of Mass and Centroid of Shape
Yifang Fan, Mushtaq Loan, Yubo Fan +2
This paper studies foot bone geometrical shape and its mass distribution and establishes an assessment method of bone strength. Using spiral CT scanning, with an accuracy of sub-mi…
Dynamic Principles of Center of Mass in Human Walking
Yifang Fan, Mushtaq Loan, Yubo Fan +2
We present results of an analytic and numerical calculation that studies the relationship between the time of initial foot contact and the ground reaction force of human gait and e…
Distribution of Primes and of Interval Prime Pairs Based on Function
Yifang Fan, Zhiyu Li
function is defined based upon Kronecher symbol. In light of the principle of inclusion-exclusion, function of sine function is used to denote the distribution of composite…
