Subgroup-closed lattice formations

open access: yesJournal of Algebra, 2015
The paper under review deals with finite groups. Therefore, the word ``group'' will mean ``finite group''. Recall that a class of finite groups that is closed under taking quotients and subdirect products is called a \textit{formation}. If every subgroup of a group in a formation \(\mathfrak F\) is also in \(\mathfrak F\), then \(\mathfrak F\) is ...

Matrix lattice Boltzmann reloaded [PDF]

open access: yes, 2011
The lattice Boltzmann equation has been introduced about twenty years ago as a new paradigm for computational fluid dynamics. In this paper, we revisit the main formulation of the lattice Boltzmann collision integral (matrix model) and introduce a new ...

Analytical solution for the lattice Boltzmann model beyond Naviers-Stokes [PDF]

open access: yes, 2010
To understand lattice Boltzmann model capability for capturing nonequilibrium effects, the model with first-order expansion of the equilibrium distribution function is analytically investigated.

Strain and atomic stacking of bismuth thin film in its quasi-van der Waals epitaxy on (111) Si substrate

open access: yesScientific Reports, 2023
We report on the structural properties of Bi thin films grown on (111) Si substrates with a thickness of 22–30 BL. HRXRD and EBSD measurements show that these Bi films are mainly composed of twinning grains in the (0003) direction.

Research on multisensor high precision data fusion algorithm for mobile robot

open access: yesDianzi Jishu Yingyong, 2018
In this paper, based on fuzzy proximity data fusion algorithm, the algorithm of multi-sensor high precision data fusion for mobile robot is studied. The estimated value and the measured value are fuzzy, and the fuzzy lattice close degree is calculated ...

Component-by-component construction of good intermediate-rank lattice rules [PDF]

open access: yes, 2003
It is known that the generating vector of a rank-1 lattice rule can be constructed component-by-component to achieve strong tractability error bounds in both weighted Korobov spaces and weighted Sobolev spaces.
