Historically in Argentina, cattle grazing occurred in extensive lands, in natural pastures. From the 90´s, cattle production increased but to the expense of a new production type, feedlots-FL or animal feeding operation ...

We propose a formulation for modeling the squeeze film air damping in perforated micro-plates typical of micro-electromechanical devices for micro switch applications. A special finite element is developed, in which the ...

Multidisciplinary and Multiphysics coupled problems represent nowadays a challenging field when studying even more complex phenomena that appear in nature and in new technologies (e.g. Magneto-Hydrodynamics, Micro-Electr ...

In this Thesis the resolution of transient free surface flow problems is considered for incompressible, viscous and Newtonian fluids, in a laminar and isothermal flow regime without surface tension effects, for two and ...

Hidden Markov models (HMM) are statistical models which can efficiently deal with sequential data. They provide a way to model complex dependencies between observed data by setting simple dependencies between latent ...

This thesis deals with different numerical methods based on finite element techniques, applicable to deterministic fracture mechanics. Within this subject, two aspects are studied: a) Evaluation of parameters wich predicts ...

Regional land-atmosphere feedbacks play an important role in the occurrence of extremes in southern South America. However, they are not fully understood. Currently, many atmospheric models have simplified land surface ...

En esta tesis se plantea el desarrollo e implementación de un método de composición de dominios tipo quimera para mallas superpuestas orientado a la resolución de problemas ingenieriles de optimización que impliquen ...

Captured 2DV patterns of river flow velocities in a cross-plane provide the basis for inferring the existence of helical flow in open-channel bends and stream confluences. Researchers usually refer to the procedure named ...

The main objective of this thesis involves the design of control systems for flight and navigation of autonomous unmanned aerial vehicles (UAVs), as well as the use and development of a simulation, visualization and flight ...

Las perturbaciones en la señal de la voz son pequeñas modificaciones de corto plazo en parámetros de la señal, cuya cuantificación resulta de importancia para el diagnóstico de patologías laríngeas, nerviosas o respiratorias. ...

In this thesis, variable source areas (VSAs) processes in plain systems, are investigated. A new hydrologic similarity Index, ISH, replacing the original topographic Index (Beven and Kirby, 1979), ITop is proposed in order ...

The occurrence of disruptive events affecting the normal performance of a plan o schedule is a well known problem for the planning activity. For this reason plans and schedules are created including slacks to deal with ...

The main objective of this work in the area of batch distillation is to develop models in order to evaluate new alternatives of separation (design, synthesis and simulation of processes) and to optimize its performance ...

This thesis reports the attempts to facilitate the access to high-performance parallel computing resources within a Python programming environment. The net result of this effort are two open source and public domain packages, ...

Globally, every urban center generates at least, two waste types can be considered renewable bio-energy sources: organic fraction of municipal solid waste and wastewater. Inexistent, poorly and low cost management describes ...
