Classication of Agricultural Fields in Satellite Images Using Two-Dimensional Hidden Markov Models
(2013)
Image segmentation is a key competence for many real life
applications such as precision agriculture. In this work we present an
approach to classify agricultural fields in noisy satellite images. We start
with the ...
Screening of some Ascomycetes and Basidiomycetes species for the production of 1- phenylethanol enantiomerically pure
(2014)
The asymmetric reduction of prochiral ketones represents a pivotal transformation for the
production of chiral alcohols. Several of them are considered as key starting materials in
obtaining pharmaceuticals.
A new approach to image segmentation with two-dimensional hidden Markov models
(2013)
Image segmentation is one of the fundamental
problems in computer vision. In this work, we present a new
segmentation algorithm that is based on the theory of twodimensional hidden Markov models (2D-HMM). Unlike most ...
Two dimensional numerical simulation for compressible flow in thermo-chemical equilibrium
(2013)
In this paper, a finite difference scheme for the solution of the unsteady and steady, two dimensional Euler equations, considering working gas in thermo-chemical equilibrium, is presented. Three variations of the Total ...
Geotechnical problems in Sierra Valle Fertil road crossing
(2015)
National Road 150 passes through the central region of Argentina and is
part of a bi-oceanic corridor from Brazil to Chile. In Sierra de Valle Fertil it has
traversed sedimentary rock formations where they have built ...
Soil carbon dynamic associated to land-use changes in semi-arid forests of Argentina
(2014)
Land-use change represents one of the main drivers of global climatic change, affecting the amount and quality of organic matter (OM) in soils worldwide. A reduction in the amount of biomass due to forest management is ...
Travelling to the south: Phylogeographic spatial diffusion model in Monttea aphylla (Plantaginaceae), an endemic plant of the Monte Desert
(2017-05)
Effects of Pleistocene climatic oscillations on plant phylogeographic patterns are relatively well studied in forest, savanna and grassland biomes, but such impacts remain less explored on desert regions of the world, ...
Demographic transition in Argentina
(2014)
Demographic transition, epidemiological transition, changes in population. And these changes in the living conditions of the
population of Argentina in the last hundred years allow us to estimate that a girl born this ...
Antioxidant activity of monoterpenes and synergist antioxidant effect with BHT
(2014)
Synthetic antioxidants are used in many foods. Their health safety is questioned.
Monoterpenesobtained from essential oils have shown antioxidant activity. The objective of this
study was to evaluate the preserving effect ...
New generalization for the intermittency theory for type I, II and III
(2014)
The concept of intermittency has been introduced by
Pomeau and Maneville in the context of the Lorenz system and are usually classified in three classes called I, II,
and III. Intermittency is a specific route to the ...
