Representing Dynamic Invariants in Ontologically Well-Founded Conceptual Models
(Universidade Federal do Espírito SantoBRPrograma de Pós-Graduação em InformáticaUFESMestrado em Informática, 2015-05-28)
Conceptual models often capture the invariant aspects of the phenomena we perceive. These invariants may be considered static when they refer to structures we perceive in phenomena at a particular point in time or ...
A patch-model for managed tropical lowland rain forests in Costa Rica
(CATIE, Turriaba (Costa Rica), 2000)
The gap modelig approach was used to develop a simulation model for Pentaclethra forests of the Central American Atlantic Moist ecoregion. The model uses empirically estimated functions fitted from a eight-years field ...
Dry sliding metals process modelling: dynamical system paradigm
(2018-11-13)
The progressive damage and material loss occurring on a component surface as a result of its movement relative to the adjacent working parts has profound economic consequences (substitution costs, inactivity of machines, ...
Validity range of stability assessments based on quasi-static phasor calculus in power systems with high levels of converter interfaced generation
(Universidad de Chile, 2022)
Power system stability is widely assessed by tools that model the network and the connected machine stators through algebraic equations and synchronous generators through differential equations, meaning that quasi-static ...
Modelos dinâmicos aplicados a sistemas de manufatura utilizando grafos de ligação: proposta de modificações
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2020-08-24)
Companies compete in a fierce market, where the main focus is consumer satisfaction, forcing
them to respond dynamically to market changes and instabilities. Due to these factors, more
accurate, adaptable, robust and ...
