The original Lamb system was introduced by Horace Lamb in 1900, [13], as a simple model for the phenomenon of radiation damping experienced by a vibrating body in an energy conducting medium. Examples include vibrations of an elastic sphere in a gaseous medium, electrical oscillations of a spherical conductor, a dielectric sphere with large inductance, relativistic radiation of energy from a co...

How realistic are these requirements? Well, noninvariance under the charge conjugation transformation (C) and the combined charge conjugation and parity reflection transformation (CP) have been observed in the laboratory. Also, thermal nonequilibrium can perhaps be expected for certain (brief) epochs in the history of the early universe, as described by the Hot Big Bang Model. But baryon number...

The use of constrained thermal expansion to tune the resonant frequency of vibrating micromechanical resonators is explored. A simple model is developed to predict the power sensitivity obtained with folded and unfolded geometries, including the effects of electrothermal heating, and conduction and convection cooling. It is shown that the sensitivity of folded structures can change sign as the ...

16. Abstract (Limit: 200 words) Poor visibility conditions often lead to large-scale chain accidents causing human fatalities and property damage. Such visibility-related vehicle accidents could have been prevented if motorists were warned ahead of time to reduce speed and remain cautious before moving into the poor visibility zone. The objective of this research was to advance the visibility m...

Patients with Raynaud's phenomenon have abnormal digital vasoconstriction in response to cold. The pathogenesis remains unknown but may involve a local neurovascular defect leading to vasoconstriction. Diagnosis of primary Raynaud's phenomenon is based on typical symptomatology coupled with normal physical examination, normal laboratory studies and lack of observable pathology by nail fold capi...

in this paper, non-polynomial spline method for solving coupled burgers’ equations are presented. we take a new spline function. the stability analysis using von-neumann technique shows the scheme is unconditionally stable. to test accuracy the error norms2l, ∞l are computed and give two examples to illustrate the sufficiency of the method for solving such nonlinear partial differential equatio...

Symmetry breaking is a common phenomenon in nonlinear systems, it refers to the existence of solutions that do not preserve the original symmetries of the underlying system. In nonlinear optics, symmetry breaking has been previously investigated in a number of systems, usually based on simplified model equations or temporal coupled mode theories. In this paper, we analyze the scattering of an i...

In vitro microtubule assembly exhibits a rhythmic phenomenon, that is, fast growth periods alternating with slow growth periods. Mechanism underlying this phenomenon is unknown. Here a simple diffusion mechanism coupled with small diffusion coefficients is proposed to underlie this phenomenon. Calculations based on previously published results demonstrate that such a mechanism can explain the d...

We investigated the theoretical possibility of applying phenomenon of synchronization of coupled nonlinear oscillators to control alternate bearing in citrus. The alternate bearing of fruit crops is a phenomenon in which a year of heavy yield is followed by an extremely light one. This phenomenon has been modeled previously by the resource budget model, which describes a typical nonlinear oscil...
