Phakopsora pachyrhizi is the major pathogen associated with soybean rust in Colombia
(2021-03-26)
Soybean crops grown in the plains of eastern Colombia have been affected by the incidence of rust. This disease, still officially regarded as American soybean rust (caused by Phakopsora meibomiae) by the Colombian Department ...
Diferencias de género en matemáticas y lengua: Rendimiento académico, autoconcepto y expectativas
(2020-04-22)
Estudios previos muestran diferencias de género en el rendimiento de matemáticas y lengua, principalmente en adolescentes. Este estudio tiene como objetivo evaluar las diferencias de género en autoconcepto, valor subjetivo, ...
A mlpg formulation for stress analysis in bi-dimensional elastic bodies
(2020-08-11)
In this work, a meshfree method known as Meshless Local Petrov-Galerkin was implemented in a bidimensional linear elasticity problem. Bidimensional MLS shape functions were used in the polynomial approximation of the ...
Biomechanical Analysis of Common Postures during Mobile Phone Use
(2020-12-24)
The use of mobile phones for long periods of time has been associated with musculoskeletal and vision symptoms. This work uses simplified biomechanical models of the head, neck, back, and forearms to estimate the forces ...
A preliminary analysis for selecting the best hydrological probability density functions of annual peak flows associated to various return periods in some rivers of Colombia
(2021-11-01)
Analysis of extreme events of annual flow peaks are used for sizing hydraulic structures for specified return period. Cumulative distribution functions are applied to annual flow peak records in order to obtain extreme ...

(2022-03-24)
This research aims to relate Information and Communication Technologies (ICT) in the processes of distribution and use of knowledge in Higher Education Institutions (HEI). The methodology used was based on the quantitative ...
A predictive model for the missing people problem
(2021-03-01)
The disappearance of people is a multidimensional phenomenon, in which several aspects must be considered. It affects people’s security perception and consumes police resources in its treatment. Therefore, does exists an ...
Performance Benchmarking of Stochastic and Deterministic Representation Bases with Compressive Sensing in Computerized Tomography Images
(2020-12-24)
Computerized tomography is a procedure that emits X-rays rotating around the body, projecting signals to be processed and converted to images. X-rays radiation in people may cause cardiovascular diseases, malformations in ...
An IDA-PBC Design with Integral Action for Output Voltage Regulation in an Interleaved Boost Converter for DC Microgrid Applications
(2021-12-29)
This paper describes the output voltage regulation control for an interleaved connected
to a direct current (DC) microgrid considering bidirectional current flows. The proposed controller
is based on an interconnection ...
Nonlinear control for a DC–DC converter with dual active bridges in a DC microgrid
(2022-10-29)
This work presents a new control strategy for a DC–DC converter with dual active bridges used to interconnect two feeders in a DC microgrid. The proposed control strategy allows regulating the output voltage of the converter ...
