LOW ORDER p-MODES IN A BIPOLYTROPIC MODEL OF THE SUN
نویسنده
چکیده
Based on the Solar Standard Model SSM we developed a solar model in hydrostatic equilibrium using two polytropes that describes both the radiative and convective zones of the solar interior. Then we apply small periodic and adiabatic perturbations on this bipolytropic model in order to obtain proper frequencies and proper functions. The frequencies obtained are in the p-modes range of low order 0 < l < 20 which agrees with the observational data, particularly with the so called five minutes solar oscillations. Subject headings: Solar Standard Model (SSM), Lane-Emden, Non Radial Oscillations (NRO), p-modes

Extension Ability of Reduced Order Model of Unsteady Incompressible Flows Using a Combination of POD and Fourier Modes
In this article, an improved reduced order modelling approach, based on the proper orthogonal decomposition (POD) method, is presented. After projecting the governing equations of flow dynamics along the POD modes, a dynamical system was obtained. Normally, the classical reduced order models do not predict accurate time variations of flow variables due to some reasons. The response of the dynam...
متن کاملDetermination of Resonance Frequency of Dominant and Higher Order Modes in Thin and Thick Circular Microstrip Patch Antennas with Superstrate by MWM (RESEARCH NOTE)
An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
