In this paper we study models based on stable probability laws which explain power spectra due to propagation of different kinds of waves in different media, for instance, acoustics in quiet or turbulent atmosphere, ultrasonics in liquids or tissues, or electromagnetic waves in free space or in ...
The energy distribution between different types of seismic waves produced by a source of longitudinal and transverse waves with an arbitrary radiation pattern in an elastic half-space is considered. With an appropriate choice of the angular distribution functions, this source can model an earthquake so...

Meng,Qing,Bin - 《Advances in Mathematical Physics》 被引量: 0发表: 2014年 TRAVELING WAVE SOLUTIONS FOR A CLASS OF NONLINEAR DISPERSIVE EQUATIONS The method of the phase plane is emploied to investigate the solitary and periodic traveling waves for a class of nonlinear dispersive partial differen...
The stability of a liquid layer flowing down an inclined plane is investigated. A new perturbation method is used to furnish information regarding stability of surface waves for three cases: the case of small wavenumbers, of small Reynol... Chia㏒hun Yih - 《Physics of Fluids》 被引量: 1065...
We study the run-up of long solitary waves of different polarities on a beach in the case of composite bottom topography: a plane sloping beach transforms into a region of constant depth. We confirm that nonlinear wave deformation of positive polarity (wave crest) resulting in an increase in...

An approach to transport measurements of electronic molecules EM (Electromagnetic) field-pattern measurements are one of the hottest subjects. Field patterning helps to understand how EM waves propagate and what kinds... I Amlani,AM Rawlett,LA Nagahara,... - 《Applied Physics Letters》 被引量: ...
However, the concentrations of viable bacteria decreased from (2.12 ± 2.04) × 104 cells·m−3 to (9.00 ± 1.72) × 103 cells·m−3 when the AQI increased from <50 to 150. The ratio of viable bacteria to total bacteria (viability) decreased from (31.0...
They observed visually the breakage of the liquid slugs, forming waves, after the sudden enlargement. In most cases, the waves will initiate the creation of new slugs. The authors also used the time signals of the pressure drop to analyze qualitatively and quantitatively the flow behavior in ...
