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) ...
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 ...

(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 ...
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 ...
Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks
(2020-08)
Automated cell counting in in-vivo specular microscopy images is challenging, especially in situations where single-cell segmentation methods fail due to pathological conditions. This work aims to obtain reliable cell ...
Toward the generation of reproducible synthetic surface data in optical metrology
(2020-05-19)
The implementation and generation of synthetic data for testing algorithms in optical metrology are often difficult to reproduce. In this work, we propose a framework for the generation of reproducible synthetic surface ...
