Adaptive finite element method for shape optimization
(Cambridge University Press, 2012-10)
We examine shape optimization problems in the context of inexact sequential quadratic programming. Inexactness is a consequence of using adaptive finite element methods (AFEM) to approximate the state and adjoint equations ...
The humerus of South American caviomorph rodents: Shape, function and size in a phylogenetic context
(Wiley Blackwell Publishing, Inc, 2013-06)
South American caviomorph rodents comprise four major lineages encompassing wide taxonomic and ecological diversity, but the morphological diversity of their postcranial skeleton has not been thoroughly explored using ...
Passivity control via Power Shaping of a wind turbine in a dispersed network
(Pergamon-Elsevier Science Ltd, 2014-05)
The connection of renewable energy conversion systems in distribution networks must comply with codes for assuring power quality as well as the grid assistance demands. The new operating requirements cannot always be ...
Can shell shape be used to find the origin of South American mussels?
(Taylor & Francis, 2021-05)
In the context of food sovereignty, it is essential to distinguish and give value to national products, especially those from artisanal production. Argentina and Chile mussel production occurs at different scales (artisanal ...
Unsupervised techniques for shape analysis of Iberian ceramics based on Geometric Morphometrics
(Jagiellonian University in Kraków, 2019)
The morphological analysis of ceramic pieces allows to establish the chronology, functionality and origin of the samples. The conformation of a typology of ceramic materials is made by analysing several aspects, such as ...
Size and shape analysis of gunflints from the British shipwreck Deltebre I (1813), Catalonia, Spain: a geometric morphometric comparison of unused and used artefacts
(Springer, 2019-09)
Gunflints represent a worldwide feature of lithic technology in modern times. This type of artefact was used to ignite the powder of firearms through a flintlock mechanismfrom the middle-seventeenth to the early-twentieth ...
Power-based control with integral action for wind turbines connected to the grid
(Taylor & Francis Ltd, 2015-10)
In this paper, a power shaping control with integral action is employed to control active and reactive powers of wind turbines connected to the grid. As it is well known, power shaping allows finding a Lyapunov function ...
Evolution of scapula shape in several families of bats (Chiroptera, Mammalia)
(Wiley Blackwell Publishing, Inc, 2020-06)
The morphological variation of the scapula of bats, in a phylogenetic context, is still unknown. However, several descriptive-comparative and morphofunctional studies about the scapular girdles and forelimbs and their ...
A theoretical model of values and behaviors that shape technology region emergence in developing contexts
(Kluwer Academic Publishers, 2020-06-25)
The research on emerging cluster regions often focuses on infrastructure that is needed to create these regions at the macro-economic level, with minimal consideration of the micro-level human factors that drive these ...
