Deep-learning potential method to simulate shear viscosity of liquid aluminum at high temperature and high pressure by molecular dynamics

open access: yesAIP Advances, 2021
The shear viscosity of matter and efficient simulating methods in a wide range of temperatures and densities are desirable. In this study, we present the deep-learning many-body potential (the deep potential) method to reduce the computational cost of ...

Heat transfer enhancement in the boundary layer flow of hybrid nanofluids due to variable viscosity and natural convection

open access: yesHeliyon, 2019
The aim of the current work is to explore how heat transfer can be enhanced by variations in the basic properties of fluids in the presence of free convection with the aid of suspended hybrid nanofluids.

Optimal detection of changepoints with a linear computational cost [PDF]

open access: yes, 2011
We consider the problem of detecting multiple changepoints in large data sets. Our focus is on applications where the number of changepoints will increase as we collect more data: for example in genetics as we analyse larger regions of the genome, or in ...

Study on MOOC scoring algorithm based on Chinese University MOOC learning behavior data

open access: yesHeliyon, 2018
Existing online learning evaluation methods do not accurately reflect learning effects, which only considers test and assignment scores. A comprehensive evaluation algorithm is proposed in this paper based on the big data of learning behavior.

Computational reverse mathematics and foundational analysis [PDF]

open access: yes, 2018
Reverse mathematics studies which subsystems of second order arithmetic are equivalent to key theorems of ordinary, non-set-theoretic mathematics. The main philosophical application of reverse mathematics proposed thus far is foundational analysis, which

Analysis of moving least squares approximation revisited

open access: yes, 2015
In this article the error estimation of the moving least squares approximation is provided for functions in fractional order Sobolev spaces. The analysis presented in this paper extends the previous estimations and explains some unnoticed mathematical ...

Computational Literacy and “The Big Picture” Concerning Computers in Mathematics Education

open access: yes, 2018
This article develops some ideas concerning the “big picture” of how using computers might fundamentally change learning, with an emphasis on mathematics (and, more generally, STEM education).
