From a Home-Area-Network to a Secure Internet of Things Application
(Springer, 2019)
In this paper, we present a secure system to control devices at home through the web, which we implement based on the Do It Yourself (DIY) culture. We use a model based on the Goal Question Metric approach to evaluate the ...
A Methodology for Driving Behavior Recognition in Simulated Scenarios Using Biosignals
(Springer, 2019)
The recognition of aggressive driving patterns could aid to improve driving safety and potentially reduce traffic fatalities on the roads. Driving behavior is strongly shaped by emotions and can be divided into two main ...
Analysis of Power Losses in Electric Distribution System Using a MATLAB-Based Graphical User Interface (GUI)
(Springer, 2019)
This paper describes a graphical user interface (GUI) developed in MATLAB that provides a user-friendly environment for analyzing the power loss behavior in distribution networks with radial configurations. This GUI allows ...
Rasch Analysis of the Q-CHAT in Colombian Toddlers with Autism Spectrum Disorder
(Springer New York LLC, 2019)
The objective of this study was the validation of the Colombian version of The Quantitative Checklist for Autism in Toddlers (Q-CHAT) by means of the Rasch Rating Scale Model. The Q-CHAT was applied to parents of 100 ...
Use of Edge Computing for Predictive Maintenance of Industrial Electric Motors
(Springer, 2019)
Industrial Internet of Things has become a reality in many kind of industries. In this paper, We explore the case of high quantity of raw data generated by a machine. In the aforementioned case is not viable store and ...
A flexible and simplified calibration procedure for fringe projection profilometry
(SPIE, 2019)
Fringe Projection Profilometry (FPP) is a widely used technique for optical three-dimensional (3D) shape measurement. Among the existing 3D shape measurement techniques, FPP provides a whole-field 3D reconstruction of ...
Integrated Methodology for the Planning of Electrical Distribution System Considering the Continuity of the Service and the Reduction of Technical Losses
(Springer, 2019)
This article presents a methodology that allows to obtain an optimal plan of re-configuration of the local distribution system to 13.2 kV, considering the improvement in the continuity of the service to the users and the ...
Computation of Electromagnetic Fields for 220 kV Power Line in Cartagena de Indias
(Springer, 2019)
The growth of the cities towards the suburban areas has caused that the buildings are construct near the lines of high voltage. This has led to detailed studies of the electric and magnetic fields generated by these lines ...
Change and variability: A framework in studies on the first year of life
(Universidad Catolica de Colombia, 2013)
This article presents empirical evidence of variability and change in the performance of young children in causality tasks, highlighting the relevance of nonlinear perspective in studies about the first year of life. Using ...
Conformastatic disk-haloes in Einstein-Maxwell gravity
(2013)
We present a relativistic model describing a thin disk surrounded by a halo in the presence of an electromagnetic field. The model is obtained by solving the Einstein-Maxwell equations on a particular conformastatic spacetime ...
