The Effect of Suspension on Parametric Stability and Bifurcation of Geared Systems in Permanent Contact Regime
Gears are known to be one of the most common mechanical parts used in rotary machinery and power transmission systems. Originally, gears are designed to remain in permanent contact regime, where the teeth in mesh do not separate during operation. But because of the clearance between the teeth in …

The robustness of H-infinity control
… are fragile. A norm was introduced called the parametric stability margin, to serve as a measure of this robustness. A fragile controller is defined as a controller that is very sensitive to changes in its controller coefficients and any small change from the nominal controller will result in …

A Low-Lunar Orbit CubeSat Solution to Mission-Oriented Lunar Surface Imagery Requirements
… in this work includes an exploration of orbital stability and an assessment of suitability for imagery objectives. The data discussed herein include a summary of the results of 3,420 individual circular orbital initial configurations in the low-lunar-orbit regime. Each orbit's data set is the …

Theoretical and Computational Analyses on Transition and Turbulence in Purely Oscillating Pipe Flow
<p>The hydrodynamic instability of purely oscillating pipe flows is investigated in terms of the quasi-steady formulation assuming the temporal changes of the laminar base flow relative to disturbances are slow. A simple model equation is introduced to compare the exact solution of the current …
