En esta tesis se realiza un estudio para reducir el número de medidores que se necesitan para implementar controladores en convertidores AC-DC. Además, se investiga la aplicación de estrategias de control no lineal co...

"In this work, a low-order model designed for glucose regulation in Type 1 Diabetes Mellitus (T1DM) is obtained from the UVA/Padova metabolic simulator. It captures not only the nonlinear behavior of the glucose-insul...

"En los últimos años se ha incrementado el número de investigaciones orientadas al desarrollo de un Páncreas Articial (AP) para la regulación automática de glucosa en pacientes con Diabetes Mellitus Tipo 1 (T1DM). ...

This paper aims to bridge the gap between neurophysiology and automatic control methodologies by redefining the Wilson-Cowan (WC) model as a control-oriented linear parameter-varying (LPV) system. A novel approach is pre...

"This work describes the use of entomological studies combined with in silico models (computer simulations derived from numerical models) to assess the efficacy of a novel device for controlled release of spatial repel...

"In this paper, a Model Predictive Control (MPC) strategy is applied to a Multilevel Current Source Inverter (MCSI) and its associated current source. The controller uses a discrete-time model of the entire system in ord...

The prospect of modifying neural activity in a principled way, could facilitate the understanding of brain functions and the development of medical treatments. To predict the dynamics that underlie the different brain ac...

We present ab initio quantum-mechanical molecular-dynamics calculations based on the calculation of the electronic ground state and of the Hellmann-Feynman forces in the local-density approximation at each molecular-dyna...

We present ab initio quantum-mechanical molecular-dynamics simulations of the liquid-metal--amorphous-semiconductor transition in Ge. Our simulations are based on (a) finite-temperature density-functional theory of the o...

BACKGROUND: The initial cases of novel coronavirus (2019-nCoV)-infected pneumonia (NCIP) occurred in Wuhan, Hubei Province, China, in December 2019 and January 2020. We analyzed data on the first 425 confirmed cases in W...

NAMD is a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems. NAMD scales to hundreds of processors on high-end parallel platforms, as well as tens of processors on lo...

In this paper, a trajectory tracking control for a nonholonomic mobile robot subjected to uncertainties and disturbances in the kinematic model is proposed. An adaptive variable structure controller based on the sliding ...

Este artículo investiga la dinámica de ingresos familiares en el corto plazo durante los años 90. La educación universitaria, como forma de protección contra caídas de ingresos, ciertos rangos demográficos asociad...

Euphorbia davidii, es una maleza anual de ciclo primavero – estival presente en los cultivos de verano en el centro y sudeste de la provincia de Buenos Aires. Para su estudio se abordaron aspectos relativos a su dinám...

El presente proyecto evaluará el impacto de las prácticas silvícolas (implantación, podas, raleos, tala) sobre la presencia, densidad y consumo de las distintas especies de hormigas cortadoras, en una cronosecuencia...

"The global energy crisis necessitates the development of sustainable energy sources, with nuclear fusion representing a significant long-term opportunity for the future. However, the licensing process for facilities lik...

Since the classical molecular dynamics simulator LAMMPS was released as an open source code in 2004, it has become a widely-used tool for particle-based modeling of materials at length scales ranging from atomic to mesos...

Spintronics, or spin electronics, involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. This article reviews the current status of this subject, including both recent ad...

En esta tesis se analizan experimental y teóricamente distintos aspectos relacionados con procesos de relajación hacia el equilibrio y transiciones de fase en copol´ımeros bloque confinados en la nanoescala. Median...

Las planicies de marea son ambientes de escasa pendiente conformados por sedimentos finos no consolidados que se desarrollan sobre costas protegidas. En esta tesis se aborda el estudio de las comunidades bentónicas de...

The dynamics and internal structure of linear sand dunes have been extensively discussed during the past decades. Several examples of this dune type, exceptionally preserved in the geologic record by transgressive events...

Las redes neuronales artificiales (ANN: Artificial Neural Networks) recientemente han tenido un gran impacto en la resolución de algunos problemas debido a que ha sido posible la implementación de algoritmos que requ...
