An approximation algorithm for the solution of the nonlinear Lane-Emden type equations arising in astrophysics using Hermite functions collocation method

, 2010
In this paper we propose a collocation method for solving some well-known classes of Lane-Emden type equations which are nonlinear ordinary differential equations on the semi-infinite domain. They are categorized as singular initial value problems.

Preconditioning fractional spectral collocation [PDF]

arXiv, 2015
Fractional spectral collocation (FSC) method based on fractional Lagrange interpolation has recently been proposed to solve fractional differential equations. Numerical experiments show that the linear systems in FSC become extremely ill-conditioned as the number of collocation points increases. By introducing suitable fractional Birkhoff interpolation

Multi-Index Stochastic Collocation for random PDEs [PDF]

, 2015
In this work we introduce the Multi-Index Stochastic Collocation method (MISC) for computing statistics of the solution of a PDE with random data. MISC is a combination technique based on mixed differences of spatial approximations and quadratures over the space of random data.

Memory Manufacture Under Microgravity (MMuM): In‐Space Manufactured ZnO‐Based Resistive Random Access Memory for Emerging Computing Application

Advanced Electronic Materials, EarlyView.
This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...
