we study the free oscillations of a non-rotating earth-like planet in the presence of a force free magnetic field. The model consists of a solid inner core, a liquid outer core and a solid mantle which is spherically symmetric. The lagrangian displacements are decomposed into scaloidal, poloidal and toroidal components using a gauged version of Helmholtz theorem. These components are identifi...
در این پایان نامه بر مقاله ی an iterative method for the symmetric and skew symmetric solutions of a linear matrix equation axb+cyd =e نوشته ی xingping sheng و guoliang chen، مروری داشته ایم. در این مقاله دو روش تکراری برای حل معادله ی ماتریسی خطی axb+cyd=e ارائه شده است. روش اول جواب معادله را به صورت متقارن و روش دوم جواب معادله را به صورت پادمتقارن ارائه می دهد. تعدادی مثال های عددی را با...
Received February 7, 2011; revised April 16, 2011; accepted April 19, 2011; posted April 19, 2011 (Doc. ID 142374); published May 19, 2011 We report analytical solutions for spatial solitons supported by layers of a quadratically nonlinear (χð2Þ) material embedded into a linear planar waveguide. A full set of symmetric, asymmetric, and antisymmetric modes pinned to a symmetric pair of the nonli...
This study examined the effects of 3 lifting ranges and 3 lifting modes on maximum lifting capability and total lifting time. The results demonstrated that the maximum lifting capability for FK (from floor to knuckle height) was greater than that for KS (from knuckle height to shoulder height) or FS (from floor to shoulder height). Additionally, asymmetric lifting with initial trunk rotation de...
We reveal the existence of asymmetric vortex solitons in ideally symmetric periodic lattices and show how such nonlinear localized structures describing elementary circular flows can be analyzed systematically using the energy-balance relations. We present the examples of rhomboid, rectangular, and triangular vortex solitons on a square lattice and also describe novel coherent states where the ...
This study is the first report of numerical solution of nonlinear bending analysis for annular and circular plates based on 3D elasticity theory with asymmetric boundary conditions using semi-analytical polynomial method (SAPM). Orthotropic annular and circular plates are subjected to transverse loading and 3D bending analysis in the presence of symmetric and asymmetric boundary conditions is s...
We introduce a new method for the visualization and simulation of the growth and developments of competing plants. In this method the plant competition for resources is illustrated as aboveand below-ground competition. The strength of the below-ground competition depends on the neighboring root biomass. The strength of the aboveground competition depends on the neighboring plant body biomass. W...
A novel semi analytical method is developed for transient analysis of single-lap adhesive joints with laminated composite adherends subjected to dynamical loads. The presented approach has the capability of choosing arbitrary loadings and boundary conditions. In this model, adherends are assumed to be orthotropic plates that pursuant to the classical lamination theory. Stacking sequences can be...
We study the effects produced by competition of two physical mechanisms of energy localization in inhomogeneous nonlinear systems. As an example, we analyze spatially localized modes supported by a nonlinear impurity in the generalized nonlinear Schrödinger equation and describe three types of nonlinear impurity modes, one- and two-hump symmetric localized modes and asymmetric localized modes, ...
