Chaotic Vibrations of the One-dimensional Wave Equation Due to a Self-excitation Boundary Condition Part I: Controlled Hysteresis
The study of nonlinear vibrations/oscillations in mechanical and electronic systems has always been an important research area. While important progress in the development of mathematical chaos theory has been made for finite dimensional second order nonlinear ODEs arising from nonlinear springs and electronic circuits, the state of understanding of chaotic vibrations for analogous infinite dim...
متن کاملPlane Wave Propagation Through a Planer Slab
An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
متن کاملPLANE WAVE PROPAGATION THROUGH A PLANER SLAB
An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...
متن کاملThe Spanish flu--Part I: the first wave.
The Spanish Flu is a term which denotes an influenza pandemic which emerged in 1918. This disease has numerous synonyms: the Spanish Flu, La Grippe espagnole, the Spanish Influenza and it is also possible to encounter throughout the world such names as the Spanish Lady or the Purple Death. The latter name resulted from the specific skin colour in the most severe cases of the diseased, who by th...
متن کاملThe Excitation of Plane Surface Waves
It is shown that a surface wave will be generated by a horizontal.slot situated above a corrugated or dielectric-coated guiding surface. A physical interpretation of the analysis is suggested which explains the mechanism of launching in terms of a resonance phenomenon allied to that which arises when a piston attenuator is terminated by a reactance equal and opposite to its own (reactive) chara...
