SPUD: Simultaneous phase unwrapping and denoising algorithm for phase imaging
(2020-05-01)
Recent methods for phase unwrapping in the presence of noise include denoising algorithms to filter out noise as a preprocessing stage. However, including a denoising stage increases the overall computational complexity ...
On the nonlinear control of a single-phase current source converter for sinusoidal voltage generation
(2020)
Colombian power system is being transformed for the large-scale integration of renewable energy resources and energy storage systems; all of these are integrated by power electronic converters controlled by voltage and ...
Soft-computing approaches for rescheluding problems in a manufacturing industry
(2020-03-02)
Flexible manufacturing systems as technological and automated structures have a high complexity for scheduling. The decision-making process is made difficult with interruptions that may occur in the system and these problems ...
A chronological literature review of electric vehicle interactions with power distribution systems
(2020-06-11)
In the last decade, the deployment of electric vehicles (EVs) has been largely promoted. This development has increased challenges in the power systems in the context of planning and operation due to the massive amount of ...
Overall heat transfer coefficient optimization in a spiral-plate heat exchanger
(2020)
Heat exchangers are widely used in the industry to allow the heat transfer between two fluids. For that reason, correctly sizing said devices poses a design problem in order to guarantee the efficiency and appropriate ...
H2 controller design on engine rotor rotation
(2020)
This article exposes the implementation of the H2 controller, which is rare in the literature because it is a more robust control and not only errors but also disturbances that can affect the dynamics of the control system ...
A mixed-integer nonlinear programming model for optimal reconfiguration of DC distribution feeders
(2020-08-27)
This paper deals with the optimal reconfiguration problem of DC distribution networks by proposing a new mixed-integer nonlinear programming (MINLP) formulation. This MINLP model focuses on minimising the power losses in ...
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) ...

(2020)
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 ...
