I. INTRODUCTION
Pioneering experiments with promising results and ironically lay unpublished is paradoxical. But that is what had happened to him as the another, years ago, in 2013. Yet, the continuing relevance of the ideas and similar pursuit by others, prompted him now in 2023, to publish his "post doctoral" works; as it knowledge matters and its chronology too!
His doctoral thesis, Anna University (2008) was on "Trifemur" a wear tester for hip joint prostheses, his patented invention. Subsequently, he augmented it as a versatile tribometer for the orthopaedic implants. Dimpled femur ball, spinal discs, special coating and lubricants could get unacceleratedly test-measured for their natural wear-life span. Pilot test runs on shells and discs proved successful, it was ready to test dimpled femur ball as well.
Parallelly, he was pursuing his other idea of tiltrotor for wind-turbine, through the guided projects for students at the Crescent Engineering College, during the years 2009, 10, 11 and 2013. Results encouraged to go for prototype of the new design.
In the midst of it all, came the retirement in 2013 at his age 65 and the abrupt freeze of the these projects due to self-imposed oblivion. Then personally, he kept himself play-fit all along by musing nonlinear dynamics, spacetime curvature, stability of the wind turbine blades and all that. Meanwhile, the efficacy of the dimpled ball in the hip joint vouched by the Arkansas University U.S., the potential of tilt-rotor wind turbine published by Korean-Japanese team in another journal, came to his notice and triggered a positive change in the beginning of 2022.
Both of his ideas gaining momentum enthused him as a pioneer! the who initiated the dimpling of femur ball, at the Indo-Japan conference I.I.T (Madras) as early as 2004 even before his Ph.D, got invigorated to salvage his "post doctoral" works freezing since 2013 and put them public for what so ever its worth.
From Jan. 2022, he resumed working on those frozen records, alone as an emeritus professor and consolidated his research findings in Jan 2023, as rubric reports entitled:-
Augmented "Trifemur" as versatile tribometer and the efficacy of dimpled femur ball in bettering the lubrication!
Tilt & Swivel type wind rotor for harnessing high winds, and the pleasant spin-off, of its kinetic resemblance to that of the Kovalevaskaya- Top, a legendary, mathematician's work.
Reporting of these two ideas: Trifemur and Tilt rotor as a sequel to their pioneering emergence decade ago and grooving relevance globally, delights the another and hopefully the reader too. Hence it is termed as rubric report - a distinguished one.
