On Domain Modelling and Requisite Variety: Current State of an Ongoing Journey
Date: 11-12-20  Score: 9,13  Percental score: 91 

In the 1950’s, W. Ross Ashby introduced the Law of Requisite Variety in the context of General Systems Theory. A key concept underlying this theory is the notion of variety, defined as the total

Direct observation of ferroelectric domain walls in LiNbO3: Wall-meanders, kinks, and local electric charges
Date: 22-09-16  Score: 9,01  Percental score: 90 

Direct observations of the ferroelectric domain boundaries in LiNbO3 are performed using high-resolution high-angle annular dark field scanning transmission electron microscopy imaging, revealing a

Low energy electron imaging of domains and domain walls in magnesium-doped lithium niobate
Date: 15-09-16  Score: 8,98  Percental score: 90 

The understanding of domain structures, specifically domain walls, currently attracts a significant attention in the field of (multi)-ferroic materials. In this article, we analyze contrast formation

Influence of defects and domain walls on dielectric and mechanical resonances in LiNbO3
Date: 23-02-17  Score: 8,81  Percental score: 88 

Monodomain and periodically poled LiNbO3 crystals (congruent composition) show dielectric and piezoelectric resonances between 100 K and 900 K. Dielectric measurements show resonances in some samples

Raman signatures of ferroic domain walls captured by principal component analysis
Date: 10-11-17  Score: 8,55  Percental score: 86 

Ferroic domain walls are currently investigated by several state-of-the art techniques in order to get a better understanding of their distinct, functional properties. Here, Principal Component

Supporting interoperability in complex adaptive enterprise systems: A domain specific language approach
Date: 15-06-16  Score: 8,51  Percental score: 85 

From a Complex Adaptive Systems (CAS) theory perspective a new approach for supporting Enterprise Interoperability (EI) is described. Particular needs informed by the theory are presented and a

Complex domain walls in BiFeO3
Date: 30-07-15  Score: 8,47  Percental score: 85 

We present an investigation of the ferroelectric and magnetic domain walls in multiferroics BiFeO3 combining first-principles structural data with a phenomenological modeling of the spin structure.

Improper ferroelectricity at antiferromagnetic domain walls of perovskite oxides
Date: 09-10-17  Score: 8,15  Percental score: 82 

First-principles calculations are performed on magnetic multidomain structures in the SmFeO3 rare-earth orthoferrite compound. We focus on the magnetic symmetry breaking at (001)-oriented antiphase

A domain specific language for spatial simulation scenarios (DSL3S): introduction and tool support
Date: 05-10-15  Score: 8,09  Percental score: 81 

Cellular automata and agent-based modelling techniques have long been used for spatial simulation in the Geographic Information Systems field. However, they largely rely on code libraries and
