(Elsevier, 2022-06)
Barchan morphometric data have been used as proxies of meteorological and topographical data in environments where this data is lacking (such as other planetary bodies), gaining insights into barchan dune field dynamics ...

Olivier, Martin S.
(Springer, 2020-08)
Constructions of science that slowly change over time are deemed to be the basis of the reliability with which scientific knowledge is regarded. A potential paradigm shift based on big data is looming – many researchers ...

The Particle Swarm Optimisation (PSO) algorithm consists of a population (or swarm) of particles that are
“flown” through an n-dimensional space in search of a global best solution to an optimisation problem.
PSO operates ...

Gruner, Stefan
(Springer, 2011-05)
On the basis of an earlier contribution to the philosophy of computer science [Ede2007] this essay discusses to what extent the ‘paradigms’ of computer science from [Ede2007] are also applicable to software engineering, ...

(Elsevier, 2019-04)
We present a technique for verifying concurrent software systems via SAT-based three-valued bounded model checking. It is based on a direct transfer of the system to be analysed and a temporal logic property into a ...

Karie, Nickson M.; Venter, H.S. (Hein)
(Wiley-Blackwell, 2014-09)
Ontologies are widely used in different disciplines as a technique for representing and
reasoning about domain knowledge. However, despite the widespread ontology-related research activities
and applications in different ...
