Sentido implicado
(Fondo Editorial Universidad EAFIT, 2016-11-01)Quien toma la decisión de leer una obra literaria con espíritu crítico se enfrenta a una pregunta: ¿qué compromiso debo asumir para recibir de esta obra todo lo que tiene para darme? El espíritu crítico tiene la respuesta, ... -
Meteorological Risk Early Warning System for Air Operations
(Institute of Electrical and Electronics Engineers Inc., 2019-01-01)Today, airspace control has the challenge of merging information from independent and heterogeneous systems in order to minimize air safety risks and facilitate the decision-making process. One of the main risks for air ... -
Standardized Approaches for Assessing Metagenomic Contig Binning Performance from Barnes-Hut t-Stochastic Neighbor Embeddings
(SPRINGER, 2020-01-01)The performance of unsupervised methods for metagenomic binning is often assessed using simulated microbial communities. The lack of well-characterized evaluation protocols and approaches to community construction cognizant ... -
Estimation of fundamental diagrams in large-scale traffic networks with scarce sensor measurements
(Institute of Electrical and Electronics Engineers Inc., 2018-01-01)The macroscopic fundamental diagram (MFD) relates space-mean flow density and the speed of an entire network. We present a method for the estimation of a 'normalized' MFD with the goal to compute specific Fundamental Diagram ... -
Mixed-Integer Linear Programming Models for One-Commodity Pickup and Delivery Traveling Salesman Problems
(Springer Verlag, 2019-01-01)This article addresses two different pickup and delivery routing problems. In the first one, called the one-commodity pickup and delivery traveling salesman problem, a known amount of a single product is supplied or demanded ... -
Emotional Networked maps from EEG signals
(Institute of Electrical and Electronics Engineers Inc., 2020-01-01)The EEG has showed that contains relevant information about recognition of emotional states. It is important to analyze the EEG signals to understand the emotional states not only from a time series approach but also ... -

Efficient use of mobile devices for quantification of pressure injury images
(IOS Press, 2018-01-01)Pressure Injuries are chronic wounds that are formed due to the constriction of the soft tissues against bone prominences. In order to assess these injuries, the medical personnel carry out the evaluation and diagnosis ... -
Emotion Recognition from EEG and Facial Expressions: A Multimodal Approach
(Institute of Electrical and Electronics Engineers Inc., 2018-01-01)The understanding of a psychological phenomena such as emotion is of paramount importance for psychologists, since it allows to recognize a pathology and to prescribe a due treatment for a patient. While approaching this ... -
A Mixed-Integer Linear Programming Model for a Selective Vehicle Routing Problem
(Springer Verlag, 2018-01-01)In this paper, we propose a new vehicle routing problem variant. The new problem is a type of selective vehicle routing model in which it is not necessary to visit all nodes, but to visit enough nodes in such a way that ... -
A Novel emotion recognition technique from voiced-speech
(IEEE, 2017-01-01)In the framework of the beginning of the investigation due to a work of an undergraduate student, the authors at Mathematical Modeling Research Group (GRIMMAT) propose the use of emotion recognition algorithms previously ... -
Short Research Advanced Project: Development of Strategies for Automatic Facial Feature Extraction and Emotion Recognition
(IEEE, 2017-10-18)Emotions are a fundamental part of the personal and social skills of the human being. The behavior, intelligence, reason and decision making process are some of the topic that can be influenced by the emotional state of a ... -
Attenuation of reverse time migration artifacts using Laguerre-Gauss filtering
(European Association of Geoscientists and Engineers, EAGE, 2017-06-12)Low-frequency artifacts appear in seismic images obtained by reverse time migration with the zero-lag crosscorrelation imaging condition due to the unwanted correlation of diving waves, head waves and backscattered waves. ... -

(IOP PUBLISHING LTD, 2017-01-01)This paper presents the development stage of a communication module for a solid propellant mid-power rocket model. The communication module was named. Simple-1 and this work considers its design, construction and testing. ... -
An approach to emotion recognition in single-channel EEG signals using stationarywavelet transform
(SPRINGER, 2017-01-01)In this work, we perform an approach to emotion recognition from Electroencephalography (EEG) single channel signals extracted in four (4) mother-child dyads experiment in developmental psychology. Single channel EEG signals ... -
Design, construction and testing of a data transmission system for a mid-power rocket model
(IEEE Computer Society, 2017-01-01)This paper presents the continuation of a previous work in the development of a communication module for a solid propellant mid-power rocket model named "Simple-1" mission. It considered the design, construction, and testing ... -
Avionics system for a mini-helicopter robot in a rapid software prototyping environment
(2010-01-01)This paper describes the hardware and software of the avionics for a mini-helicopter robot called Colibrí, which provides the instrumentation, intelligence, and energy to the autonomous navigation. The paper describes the ... -
A simple but efficient voice activity detection algorithm through Hilbert transform and dynamic threshold for speech pathologies
(IOP PUBLISHING LTD, 2016-01-01)A simple but efficient voice activity detector based on the Hilbert transform and a dynamic threshold is presented to be used on the pre-processing of audio signals. The algorithm to define the dynamic threshold is a ... -
Multiresolution analysis (discrete wavelet transform) through Daubechies family for emotion recognition in speech.
(IOP PUBLISHING LTD, 2016-01-01)We propose a study of the mathematical properties of voice as an audio signal. This work includes signals in which the channel conditions are not ideal for emotion recognition. Multiresolution analysis- discrete wavelet ... -
Double Fourier analysis for Emotion Identification in Voiced Speech
