Zero-electric-power position retaining utilizing hysteresis on an antagonistic shape memory alloy system

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Shape Memory Alloy (SMA) actuators must be continued to be heated generally to retain a shape of a smart structure deformed by the SMA actuators. To save the energy applying to the smart structure, a new control method was proposed utilizing the fact ...

Analytical Model of the Time Developing Turbulent Boundary Layer

open access: yes, 2007
We present an analytical model for the time-developing turbulent boundary layer (TD-TBL) over a flat plate. The model provides explicit formulae for the temporal behavior of the wall-shear stress and both the temporal and spatial distributions of the ...
