Power flow methods used in AC distribution networks: An analysis of convergence and processing times in radial and meshed grid configurations
(2023-01-23)
The load flow problem (LFP) in power distribution networks allows us to find the nodal voltage values within the electrical systems. These values, along with the system parameters, are useful to identify the (technical,economic, ...
Multiclass Land Use and Land Cover Classification of Andean Sub-Basins in Colombia with Sentinel-2 and Deep Learning
(2023-05-11)
Land Use and Land Cover (LULC) classification using remote sensing data is a challenging problem that has evolved with the update and launch of new satellites in orbit. As new satellites are launched with higher spatial ...

The aim of this study is to identify and analyze the cultural damage caused by the armed conflict in the black peasant community of San Cristóbal, in Montes de María, one of the regions most affected by the prolonged ...
Reduction of annual operational costs in power systems through the optimal siting and sizing of STATCOMs
(2021-04-17)
The problem of the optimal siting and placement of static compensates (STATCOMs) in
power systems is addressed in this paper from an exact mathematical optimization point of view. A
mixed-integer nonlinear programming ...
Solid-state photocatalysis for plastics abatement: A review
(2022-06-17)
The COVID-19 pandemic has caused a dramatic increase in plastic wastes associated with the use of single-use masks, gloves, gowns, and other personal protective equipment (PPE). The accumulation of PPE, especially single-use ...
Performance evaluation of structures with reinforced concrete columns retrofitted with steel jacketing
(2021-01)
Several existing reinforced concrete (RC) buildings fail to conform with current seismic codes, increasing its susceptibility to damage and collapse during earthquakes. A concern for building upgrading and rehabilitation ...
Hydrological considerations for sizing of a barge discharge pipeline runway
(2021-11-01)
A key element for water supply systems is the design of the water intake components. Mobile floating platforms (barges) are helpful when the hydraulic system displays substantial variations in water levels. This study ...
