This study evaluates the impact of knowledge spillovers on the convergence of productivity among firms. With the use of patent citation data, knowledge spillovers are decomposed into intraand inter-industry spillovers, and internal knowledge flows. The findings from this study suggest that each firm is converging to its own steady-state productivity growth rate, which is conditional on the firm...

Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. Laminar blood flow is assumed to have both Newtonian and non-Newtonian behavior (generalize...

The explosive viscous liquid becomes inject to warhead by discharge system. The injection device is consisted of a piston to move down and leads the viscous fluid through the cylindrical pipe towards the end of the duct. Then the viscous fluid leads into a convergent path that will be injected to the warhead or other injection equipment. In this project, the path of viscous fluid flow is divide...

We define two conformal structures on S which give rise to a different view of the affine curvature flow and a new curvature flow, the “Qcurvature flow”. The steady state of these flows are studied. More specifically, we prove four sharp inequalities, which state the existences of the corresponding extremal metrics.
