In this paper, the modified Euler-Bernoulli beam model is presented to examine the influence of surface elasticity and residual surface tension on the critical force of axial buckling of nanotubes in the presence of rotary inertia. An explicit solution is derived for the buckling loads of microscaled Euler beams considering surface effects. The size-dependent buckling behavior of the nanotube d...

Nomenclature β,γ(∈ S) = The gimbal and wheel angles. (rad) Rβ(∈ SO(3)) = Transformation from gimbal frame G to the spacecraft body frame B. Is = Spacecraft inertia without the CMG gimbal and wheel inertia. (kg.m) Ig, Ir = Gimbal frame inertia, wheel inertia about own centre of mass represented in gimbal frame. (kg.m) (Igr)β = Combined inertia of gimbal frame and wheel in the spacecraft frame. R...

The goal of our study is to obtain a precise dynamic model by applying the technique of system identification for the model-based control of a nonlinear robot arm, taking joint-elasticity into consideration. We previously proposed “decoupling identification method” for a planar serial two-link robot arm with elastic-joints caused by the Harmonicdrive reduction gears. First, this paper reviews t...

When a new brand is launched, consumers are initially both uncertain of and not inertial to the new brand. Though these barriers may disappear on their own over time, a savvy brand manager who knows the relative importance of both can use relevant marketing levers to increase profits in the long run. This paper studies exactly these barriers and measures their relative effects on the launch of ...

<p style="text-indent:20px;">We present a second-order extension of the first-order Lohe Hermitian sphere (LHS) model and study its emergent asymptotic dynamics. Our proposed incorporates an inertial effect as extension. The inertia term can generate oscillatory behavior particle trajectory in small time interval(initial layer) which causes technical difficulty for application monotonicit...
