The Acoustic Analogy as a Tool of Computational Aeroacoustics region. The generalization of Lighthill’s equation in the presence of moving surfaces by Ffowcs Williams and Hawkings in 1969 was a major advance. The primary impact of the governing equation of noise generation known as the Ffowcs Williams-Hawkings (FW-H) equation has been in the prediction of the

Relationship of the Boundary of an Integral Funnel with the Hamilton-Jacobi Equation,d, z (q, t) is an unknown scalar function. A large number of remarkable works are devoted to this equation (see, for example, ). A geometrical interpretation of this equation is as follows. We fix a point (q’, t’) in {q, t}, and from this point draw a vector (P, P.) = (∂z/∂q, ∂z/∂t

Bank Debt, Growth Opportunities and Corporate Investment Behavior,creditors. So, this paper proposes that the “control effect” of the liabilities mainly comes from bank debt. To verify the above assumption, we use the data of listed firms during 2008–2010 to examine the bank debt-investment relationship. The result shows that bank debt has a negative effect on cor

Processing Emulsified Oils and Alkyds to Generate Polymers has switched to water-borne latex coatings based on petroleum derived materials. The major reason for this is consumer convenience in clean-up, short dry times and low odor. As paints based on these products further penetrate the existing market, the usage of vegetable oil-based coatings will continue to decline.
