A Comparative Study on Power Flow Methods Applied to AC Distribution Networks with Single-Phase Representation
(2021-10-21)
This paper presents a comparative analysis of six different iterative power flow methods applied to AC distribution networks, which have been recently reported in the scientific literature. These power flow methods are (i) ...
A Discrete-Continuous PSO for the Optimal Integration of D-STATCOMs into Electrical Distribution Systems by Considering Annual Power Loss and Investment Costs
(2022-07-14)
Currently, with the quick increase in global population, the energetic crisis, the environmental problematic, and the development of the power electronic devices generated the need to include new technologies for supporting ...
LQR-Based adaptive virtual inertia for grid integration of wind energy conversion system based on synchronverter model
(2021-03-06)
This paper proposes adaptive virtual inertia for the synchronverter model implemented in a wind turbine generator system integrated into the grid through a back-to-back converter. A linear dynamic system is developed for ...
Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...
Direct Power Control Design for Charging Electric Vehicles: A Passivity-Based Control Approach
(2020-11-25)
This paper explores the controller's design for charging batteries for electric vehicle applications using the direct power representation of the system. These controllers' design is made via passivity-based control (PBC) ...
Application of Pyrolysis for the Evaluation of Organic Compounds in Medical Plastic Waste Generated in the City of Cartagena-Colombia Applying TG-GC/MS
(2023-03-11)
In this study, the thermal degradation and pyrolysis of hospital plastic waste consisting of polyethylene (PE), polystyrene (PS), and polypropylene (PP) were investigated using TG-GC/MS. The identified molecules with the ...
Trade-Off Asymmetric Profile for Extended-Depth-of-Focus Ocular Lens
(2022-02-19)
We explore the possibility of extending the depth of focus of an imaging lens with an
asymmetric quartic phase-mask, while keeping the aberration within a relatively low level. This can be intended, for instance, for ...

El presente trabajo es un informe general de las características de modelo de negocio de una aplicación que proporcionaría conexión directa entre clientes y proveedores de diferentes servicios de mantenimiento doméstico ...
Hybrid calibration method for improving 3D measurement accuracy of structured light systems
(2020-08-21)
In structured-light systems, the lens distortions of the camera and the projector reduce the measurement accuracy when calibrated as a standard stereo-vision system. The conventional compensation via distortion coefficients ...
A low-cost multi-modal medical imaging system with fringe projection profilometry and 3D freehand ultrasound
(2020-01-03)
The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations ...
