Mathematical model and manufacturing of a human or a robotic knee joint
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 This paper proposed two imaginary planar rack-cutters to create a spherical gear pair with ring-involute teeth. The spherical gear pair can be used to a knee joint mechanism. The imaginary planar rack cutter consists of two kinds of conical tooth. One is

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...
