Disequilibrium and variational inequalities

open access: bronzeJournal of Computational and Applied Mathematics, 1990
AbstractIn this paper we introduce a new market disequilibrium model in a spatial economic setting, which generalizes a recent spatial disequilibrium model to the asymmetric case. We derive two alternative variational inequality formulations of the market conditions, in the case of price rigidities and/or controls, and discuss existence and uniqueness ...

Well-Doublets: A First-Order Assessment of Geothermal SedHeat Systems

open access: yesApplied Sciences, 2021
Renewable and sustainable energy sources can play an important role in meeting the world’s energy needs and also in addressing environmental challenges such as global warming and climate change. Geothermal well-doublet systems can produce both electrical

The Permutation Entropy and its Applications on Fire Tests Data [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
Based on the data gained from a full-scale experiment, the order/disorder characteristics of the compartment fire temperatures are analyzed. Among the known permutation/encoding type entropies used to analyze time series, we look for those that fit ...

Implementation of disequilibrium chemistry to spectral retrieval code ARCiS and application to sixteen exoplanet transmission spectra: Indication of disequilibrium chemistry for HD 209458b and WASP-39b [PDF]

open access: yesA&A 656, A90 (2021), 2021
The retrieval approach is currently a standard method for deriving atmospheric properties from observed spectra of exoplanets. However, the approach ignores disequilibrium chemistry in most current retrieval codes, which can lead to misinterpretation of the metallicity or elemental abundance ratios of the atmosphere.

Dynamic management needs for long‐lived, sporadically recruiting plant species in human‐dominated landscapes

open access: yesPlants, People, Planet, 2020
Societal Impact Statement Long‐lived, iconic plant species like the baobab, welwitschia, the saguaro cactus or the dragon's blood tree are perceived to be everlasting landscape features due to their pronounced longevity.
