Substituted heterocycles as new candidates for liquid organic hydrogen carriers: In silico design from DFT calculations
(2021-02-24)
A new set of compounds based on N- and S-heterocycles were investigated through Density Functional Theory (DFT) for their use as liquid organic hydrogen carriers (LOHCs). The hydrogenated forms of these compounds could ...
Multi-target Attachment for Surgical Instrument Tracking
(2021-06-16)
The pose estimation of a surgical instrument is a common problem in the new needs of medical science. Many instrument tracking methods use markers with a known geometry that allows for solving the
instrument pose as ...
Skin prick test wheal detection in 3D images via convolutional neural networks
(2021-10-01)
The skin prick test (SPT) is performed to diagnose different types of allergies. This medical procedure requires measuring the size of the skin wheals that
appear when the test is performed. However, the manual measurement ...
Desarrollo e implementación de un perfilómetro óptico por triangulación láser
(2020-12-24)
Profilometers are instruments commonly used in surface metrology tasks. These instruments play a key role in the industry, such as in manufacturing and quality assurance. However, conventional profilometry techniques require ...
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 ...
Toward an adaptive protection scheme in active distribution networks: Intelligent approach fault detector
(2021-01)
Conventional protection schemes have proven insufficient for the protection of Active Distribution Networks (ADN). Novel protection schemes with an adaptive approach should be developed to guarantee the protection of ADN ...
On the mathematical modeling for optimal selecting of calibers of conductors in DC radial distribution networks: An MINLP approach
(2021-01-29)
This paper addresses the problem of optimal conductor selection in direct current (DC) distribution networks with radial topology. A nonlinear mixed-integer programming model (MINLP) is developed through a branch-to-node ...
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 ...
Improved genetic algorithm for phase-balancing in three-phase distribution networks: A master-slave optimization approach
(2021-05-14)
This paper addresses the phase-balancing problem in three-phase power grids with the
radial configuration from the perspective of master–slave optimization. The master stage corresponds
to an improved version of the Chu ...
