This paper presents a magnetostrictive in-pipe impact drive mechanism (IDM). To estimate the output performances of the IDM, a dynamics model was developed based on the magnetostrictive material constitutive model and mechanical model of the IDM. Therefore, an experimental system has been built to test the motion performance of IDM. Simulation and experimental results illustrate that the propos...

Abstract D emonetization initiative by Govt. of India in Nov-Dec, 2016 aimed at addressing the issues like black money, hoarding and overall cleansing the monetary system. This paper in this regard attempts to empirically examine the impact of demonetization drive upon the monetary system by taking data of 180 days prior to Nov, 2016. The cointegration results exhibit show a long run ...

A smooth impact drive mechanism (SIDM) is one type of piezoelectric actuator that has been put into practical use. In previous SIDMs, soft-type multilayered piezoelectric elements with low mechanical quality factors were utilized, which meant it was difficult to generate high output power, and the multilayered structure was an obstacle to further miniaturization. We have proposed a resonant-typ...

GAMs oscillate between states of strong rotation and up-down asymmetric plasma compression. Hence, at first glance the natural turbulent drive (or damping) mechanisms for them is either a direct boost of the rotation – via Reynolds stress – or the creation of asymmetric pressure distributions – via transport. However, an up-down asymmetric pressure can also be created by the divergence of the d...
