No such thing as a free lunch: interaction costs and the structure and stability of mutualistic networks
(WILEY, 2020)
Different modelling approaches have been used to relate the structure of mutualistic interactions with the stability of communities. However, inconsistencies arise when we compare modelling outcomes with the patterns of ...
A robust design for a Colombian dairy cooperative's milk storage and refrigeration logistics system using binary programming
(International Journal of Production Economics, 2017-01)
This article describes a robust design for a milk storage and refrigeration logistics system for a dairy cooperative located in the Ubaté region of Colombia using a binary programming model. Such design included cooling ...
Arcabouço comparativo de ferramentas para integração semântica de dados tabulares
(Universidade Federal de Minas GeraisBrasilECI - DEPARTAMENTO DE TEORIA E GESTÃO INFORMAÇÃOUFMG, 2020-11)
Comma-Separated Values (CSV) is used due to its low computational cost, on the other hand it is necessary to integrate it with a high-level repository to aggregate value to the data. In addition, Linked Data (LD) brought ...

Endogenous time-dependent rules and the costs of disinflation with imperfect credibility
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2003-10-09)
This paper examines the output effects of monetary disinflation in a model with endogenous time-dependent pricing rules and imperfect credibility of the disinflation policy. We find that these features interact to generate ...

Currently, we witness the severe spread of the pandemic of the new Corona virus, COVID-19,
which causes dangerous symptoms to humans and animals, its complications may lead to death.
Although convolutional neural networks ...
Efficient approach for interest points detection in non-rigid shapes
(Computing Conference (CLEI), 2015 Latin American, 2015-12-17)
Due to the increasing amount of data and the reduction of costs in 3D data acquisition devices, there has been a growing interest, in developing efficient and robust feature extraction algorithms for 3D shapes, invariants ...
Competition-driven evolution of organismal complexity
(2019)
Author summary We provide a theoretical proof-of-principle explanation for the empirically well-documented macroevolutionary pattern of punctuated changes in organismal complexity. According to such patterns, many phenotypic ...
