(2019-06-10)Shale swelling causes 90% of wellbore instabilities and oil-base muds (OBM) have been the best choice for many years. However, the stringent environmental concern have resulted in a keen interest in the development of ...

(2018-08-06)We study the nonlinear Dirac equation with Soler-type nonlinearity in one dimension (which is called the Gross-Neveu model), with the nonlinearity localized at one and at two points. We study the spectral stability of the ...

(Texas A&M University, 2004-09-30)Internal friction has been known to be a cause of whirl instability in built-up rotors since the early 1900's. This internal damping tends to make the rotor whirl at shaft speeds greater than a critical speed, the whirl ...

(2015-09-11)Transient growth is a linear disturbance growth mechanism that plays a key role in roughness-induced boundary-layer transition. It occurs when superposed stable, non-orthogonal continuous spectrum modes experience algebraic ...
