Desarrollo de un prototipo IoT para la automatización del riego en invernaderos agrícolas sostenibles

Sergio Andrés Hurtado Vargas · Diego Alejandro Gutiérrez Naranjo · Javier Eduardo Martínez Baquero

La agricultura de precisión requiere soluciones tecnológicas que optimicen el uso del agua y mejoren el monitoreo de las variables ambientales en cultivos protegidos. Este trabajo presenta el diseño, implementación y validación de un prototipo IoT para el monitoreo y control automático del riego en un invernadero desti...

Spectroscopy of excited neutron configurations of Ca 54

F. Browne · S. Chen · P. Doornenbal · A. Obertelli · y 79 más

Despite its nucleon numbers not coinciding with the traditional nuclear magic numbers, the structure of Ca 54 shows signatures of a doubly closed shell nucleus. This article details the structures of neutron-excited states up to beyond the two-neutron emission threshold populated by the Ca 55 ( p , p n ) reaction at ∼...

Decision technologies in control engineering: A scientometric review of LQR control for inverted pendulum systems (2006–2025)

Ronald-Steven Pérez-Baquero · Juan Pablo Murgas Gutierrez · Alex Camilo Arzuaga Gomez · Cristian Duban Suarez Ravelo

The inverted pendulum is a paradigmatic model frequently employed to validate control techniques in unstable systems. Among the most widely used strategies, the linear quadratic regulator (LQR) is distinguished by its robustness, well-defined optimality criteria, and mathematical simplicity, thus establishing itself as...

Mapping the human side of projects: Global scientometric insights into communication, leadership, and stakeholder engagement (2005–2025)

Fabian-Andres Delgado · Edilson Ibarra-Beltran

The success of project management is contingent upon the development of essential competencies, including communication, management, leadership, team coordination, and stakeholder management. However, the possession of these skills alone does not guarantee the achievement of project objectives. In this context, this st...

Nutritional Value of Biofloc Meal for White Cachama ( Piaractus orinoquensis ): Effects of Inclusion Level on Digestibility, Growth Performance, and Protein Retention

Natalia Álvarez‐Perdomo · Carlos Arturo David Ruales · Luis Felipe Collazos Lasso · Laura Suarez Contento · y 1 más

ABSTRACT Biofloc technology (BFT) offers a sustainable aquaculture strategy; however, the value of its byproduct, biofloc meal (BFM), as a feed ingredient requires validation for key species. This study evaluated the use of BFM from a tilapia–molasses system as a feed ingredient for white cachama ( Piaractus orinoquens...

A su ingreso al servicio de urgencias se registró una frecuencia cardiaca de 125 latidos por minuto, 30 respiraciones por min...

Power Flow Analysis in Unbalanced Distribution Networks with Single-Phase and Two-Phase Laterals Using a Fixed-Point Formulation Implemented in MATLAB

Cristian David Cuervo-Gonzalez · John Fredy Pinilla-Morales · Oscar Danilo Montoya Giraldo

This paper proposes a fixed-point methodology for power flow analysis in unbalanced three-phase distributionnetworks featuring mixed single-phase, two-phase, and three-phase laterals—a common configuration in rural and low-voltage distribution systems. The method addresses the convergence challenges posed by low X/R ra...
