Stability of trapped degenerate dipolar Bose and Fermi gases
(2013-06-14)
Trapped degenerate dipolar Bose and Fermi gases of the cylindrical symmetry with the polarization vector along the symmetry axis are only stable for the strength of dipolar interaction below a critical value. In the case ...
A numerical study of the 1/2, 2/1, and 1/1 retrograde mean motion resonances in planetary systems
(Oxford Univ Press, 2022-07-29)
We present a numerical study on the stability of the 1/2, 2/1, and 1/1 retrograde mean motion resonances in the three-body problem composed of a solar mass star, a Jupiter mass planet, and an additional body with zero mass ...
Comparison between Laplace-Lagrange secular theory and numerical simulation: the case of υ Andromedae planetary system
(2018-12-01)
The large increase in exoplanet discoveries in the last two decades showed a variety of systems whose stability is not clear. In this work, we chose the υ Andromedae system as the basis of our studies in dynamical stability. ...
Consistent and stable meshfree Galerkin methods using the virtual element decomposition
(Wiley, 2017)
Over the past two decades, meshfree methods have undergone significant development as a numerical tool
to solve partial differential equations (PDEs). In contrast to finite elements, the basis functions in meshfree
methods ...
An Efficient Galerkin BEM to Compute High Acoustic Eigenfrequencies
(ASME-AMER SOC MECHANICAL ENG, 2009)
An efficient numerical method, using integral equations, is developed to calculate precisely the acoustic eigenfrequencies and their associated eigenvectors, located in a given high frequency interval. It is currently known ...
Three-dimensional effect of stresses in open stope mine design
(Taylor and Francis Ltd., 2018)
The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
A semi-empirical stability criterion for real multi-planetary systems with eccentric orbits
(Wiley-blackwell Publishing, Inc, 2013-12)
We test a crossing orbit stability criterion for eccentric planetary systems, based on Wisdom´s criterion of first order mean motion resonance overlap citep{Wisdom1980AJ}. We show that this criterion fits the stability ...
A simple and less conservative test for D-stability
(Siam PublicationsPhiladelphiaEUA, 2004)
Investigating the ESBWR stability with experimental and numerical tools: A comparative study
(Elsevier Science SA, 2010-02)
In this work, the stability of the Economic Simplified Boiling Water Reactor (ESBWR) has been studied by using a Freon-134a based experimental facility (GENESIS) and two system codes, being ATHLET 2.0a and (to a lesser ...
