In a time of heightened environmental concerns and increased importance on efficiency, thermoacoustic standing waves and oscillations provide a possible solution to many contemporary problems. Elementary standing wave theory is discussed, as well as the connection between thermodynamics and acoustical oscillations. Additionally, the benefits of Sondhauss oscillations and devices for their produ...

The cubic complex one-dimensional Ginzburg–Landau equation is considered. Using the Hone’s method, based on the use of the Laurent-series solutions and the residue theorem, we have proved that this equation has neither elliptic standing wave no elliptic travelling wave solution. This result amplifies the Hone’s result, that this equation has no elliptic travelling wave solution.

Explosions occur in military conflicts as well as in various industrial applications. Air blast waves generated by large explosions move outward with high velocity, pressure and temperature. The blast waves not only incapacitate military and civilian personnel, but also damages buildings, vehicles, and other properties. Hence, there has been extensive research on how to mitigate blast wave effe...
