On some families of subsemigroups of a numerical semigroup
(2020-04-07)
To a given numerical semigroup S we associate a family of subsemigroups {휕nS}, n ∈ ℕ, that permits us to understand some of the structure of S. We characterize this family in case S is a supersymmetric numerical semigroup ...

Infrastructure and rurality: Challenges for sustainable economic development in Latin America
(2020)
Latin America is a region with a great environmental and cultural diversity; however, most of its countries have high levels of poverty and inequality, characteristics that are accentuated in rural areas. This paper ...
Design of an electrogoniometer based on accelerometers for the evaluation of sports gesture in weight lifting
(Institute of Electrical and Electronics Engineers Inc., 2014)
This article describes the design and implementation of an electrogoniometer to measure joint angles during the execution of weight lifting exercises. The electrogoniometer consists of four microelectromechanical accelerometers ...
Modeling of dynamic mass coupled system with Runge-Kutta fourth order
(Institute of Physics Publishing, 2019)
This paper shows the mathematical modeling process of a mechanical system of masses coupled by two springs and a shock absorber. The process of capture of movement of the mass system coupled with springs was done with ...
Designing Fresnel microlenses for focusing astigmatic multi-Gaussian beams by using fractional order Fourier transforms
(Institute of Physics Publishing, 2011)
According to a scalar theory of diffraction, light propagation can be expressed by two-dimensional fractional order Fourier transforms. Since the fractional Fourier transform of a chirp function is a Dirac distribution, ...
Automatic recognition of Colombian car license plates using convolutional neural networks and Chars74k database
(2020)
A methodology for the automatic recognition of Colombian car license plates using convolutional neural networks is proposed. One of the biggest challenges when using onvolutional neural network is the demand for large ...
Multi-server approach for high-throughput molecular descriptors calculation based on multi-linear algebraic maps
(Wiley-VCH Verlag, 2015)
The present report introduces a novel module of the QuBiLS-MIDAS software for the distributed computation of the 3D Multi-Linear algebraic molecular indices. The main motivation for developing this module is to deal with ...
Toward an automatic 3D measurement of skin wheals from skin prick tests
(SPIE, 2019)
The skin prick test (SPT) is the standard method for the diagnosis of allergies. It consists in placing an array of allergen drops on the skin of a patient, typically the volar forearm, and pricking them with a lancet to ...
