Numerical methods for fractional diffusion [PDF]

open access: yesComputing and Visualization in Science, 2018
We present three schemes for the numerical approximation of fractional diffusion, which build on different definitions of such a non-local process. The first method is a PDE approach that applies to the spectral definition and exploits the extension to one higher dimension.

The effect of the friction pendulum isolation system on the seismic response of structures located on different types of soils [PDF]

open access: yesمجله مدل سازی در مهندسی, 2022
Conventional seismic design and reinforcement methods are based on increasing the capacity of the structure. That is, the bearing capacity of the structure is increased by increasing its strength and ductility, which is not possible in the reinforcement ...

Numerical methods with Sage

open access: yesTbilisi Mathematical Journal, 2012
Numpy and SciPy are program libraries for the Python scripting language, which apply to a large spectrum of numerical and scientific computing tasks. The Sage project provides a multiplatform software environment which enables one to use, in a unified way, a large number of software components, including Numpy and Scipy, and which has Python as its ...

Efficiency of Higher Order Finite Elements for the Analysis of Seismic Wave Propagation [PDF]

open access: yes, 2000
The analysis of wave propagation problems in linear damped media must take into account both propagation features and attenuation process. To perform accurate numerical investigations by the finite differences or finite element method, one must consider ...
