Stochastic finite element method with simple random elements [PDF]

open access: yes, 2008
We propose a variant of the stochastic finite element method, where the random elements occuring in the problem formulation are approximated by simple random elements, i.e.

Construction of strong mammalian promoters by random cis-acting element elongation

open access: yesBioTechniques, 2007
Synthetic oligonucleotides containing one of four kinds of cis-acting elements, binding sites for activating protein-1 (AP-1), nuclear factor κB (NF-κB), CArG binding factor A (CBF-A), and nuclear factor Y (NF-Y), were randomly ligated to construct DNA ...

Generating Random Elements in Finite Groups [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2008
Let $G$ be a finite group of order $g$. A probability distribution $Z$ on $G\ $is called $\varepsilon$-uniform if $\left\vert Z(x)-1/g\right\vert \leq\varepsilon/g$ for each $x\in G$. If $x_{1},x_{2},\dots,x_{m}$ is a list of elements of $G$, then the random cube $Z_{m}:=Cube(x_{1},\dots,x_{m}) $ is the probability distribution where $Z_{m}(y)$ is ...

Predicting the Probability of Failure of Cementitious Sewer Pipes Using Stochastic Finite Element Method [PDF]

open access: yes, 2015
In this paper, a stochastic finite element method (SFEM) is employed to investigate the probability of failure of cementitious buried sewer pipes subjected to combined effect of corrosion and stresses.

Finite element modeling and random vibration analysis of BGA electronic package soldered using lead free solder alloy − Sn-1Cu-1Ni-1Ag

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2019
As a result of the ban of lead from solder joints, many lead-free solder joints were developed. Most of the electronic equipment is subjected to random vibration.

Numerical methods for boundary value problems on random domains [PDF]

open access: yes, 2014
In this thesis, we consider the numerical solution of elliptic boundary value problems on random domains. The underlying domain is modelled via a random vector field which is given by its mean and its covariance.

Design of a wideband random phase gradient metasurface by using line-shaped element

open access: yesJournal of Advanced Dielectrics, 2020
Based on phase randomization theory, a method for manufacturing metasurface with diffuse scatter performance is proposed. By using the line-shaped elements with random rotate angles and random distributing positions, the metasurface can achieve good ...

Solution of Static Field Problems With Random Domains [PDF]

open access: yes, 2010
A method to solve stochastic partial differential equations on random domains consists in using a one-to-one random mapping function which transforms the random domain into a deterministic domain.
