Approximation of Probability Density Functions for PDEs with Random Parameters Using Truncated Series Expansions [PDF]
Vietnam Journal of Mathematics, 2021 The probability density function (PDF) of a random variable associated with the solution of a partial differential equation (PDE) with random parameters is approximated using a truncated series expansion. The random PDE is solved using two stochastic finite element methods, Monte Carlo sampling and the stochastic Galerkin method with global polynomials.

A High Order Theory for Linear Thermoelastic Shells: Comparison with Classical Theories
Journal of Engineering, 2013 A high order theory for linear thermoelasticity and heat conductivity of shells has been developed. The proposed theory is based on expansion of the 3-D equations of theory of thermoelasticity and heat conductivity into Fourier series in terms of ...

Adiabatic series expansion and higher-order semiclassical approximations in scattering theory [PDF]
Journal of Physics A: Mathematical and Theoretical, 2014 The scattering properties of any complex scattering potential, v:R -> C, can be obtained from the dynamics of a particular non-unitary two-level quantum system S_v. The application of the adiabatic approximation to S_v yields a semiclassical treatment of the scattering problem.

Approximate Trigonometric Series Expansions of Some Bounded Solutions in the Tsien Problem [PDF]
Journal of Guidance, Control, and Dynamics, 2019 INTHE last decades, studies on the dynamics of a spacecraft that is moving in the gravitational field of a celestial body and subjected to some low-thrust propulsion system have attracted the attention of many researchers in astrodynamics. Here, we consider a particular case, the so-called Tsien problem [1], in which the spacecraft moves in a circular ...
