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 ...
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 ...
AZG2 transporter plays a key role in auxin/cytokinin lateral root development regulation
(2015)
AZG (AZa-Guanin resistant) is a gene family first described in fungi as purine transporters. Two members of this family, Azg1 and Azg2, are encoded in the Arabidopsis genome. Although they are able to transport purines ...
What is the real isotopic signature of dust emitted from Tierra del Fuego?
(2015)
Sugden et al. (2009) suggested an on/off switch mechanism that could explain the 20 times increase of dust deposition in Antarctica during the Last Glacial Maximum (LGM), as compared to present day. This suggested switch ...
Mosquito larval habitat ecology in the cold arid Patagonia region of Argentina
(2015)
Knowledge of mosquito ecology in the southern Argentine Patagonia region
remains restricted mainly to geographic distributions and some habitat descriptions. There
has been no comprehensive study of the ecology of larvae ...
