Methodology of Machine Learning for the classification and Prediction of users in Virtual Education Environments
(Centro de Informacion Tecnologica, 2019)
A methodology to classify and predict users in virtual education environments, studying the interaction of students with the platform and their performance in exams is proposed. For this, the machine learning tools, main ...
Occurrence of personal care products as emerging chemicals of concern in water resources: A review
(Elsevier B.V., 2017)
Personal care products (PCPs) are a diverse group of common household substances used for health, beauty and cleaning purposes. These include disinfectants, fragrances, insect repellents, preservatives and UV filters, among ...
Emptying operation of water supply networks
(MDPI AG, 2017)
Recently, emptying processes have been studied in experimental facilities in pipelines, but there is a lack regarding applications in actual pipelines, which permits establishing the risk of collapse because of sub-atmospheric ...
Experimental and numerical analysis of a water emptying pipeline using different air valves
(MDPI AG, 2017)
The emptying procedure is a common operation that engineers have to face in pipelines. This generates subatmospheric pressure caused by the expansion of air pockets, which can produce the collapse of the system depending ...
Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis
(MDPI AG, 2019)
The filling process in water pipelines produces pressure surges caused by the compression of air pockets. In this sense, air valves should be appropriately designed to expel sufficient air to avoid pipeline failure. Recent ...
Effect of the non-stationarity of rainfall events on the design of hydraulic structures for runoff management and its applications to a case study at Gordo Creek watershed in Cartagena de Indias, Colombia
(MDPI AG, 2018)
The 24-h maximum rainfall (P 24h-max ) observations recorded at the synoptic weather station of Rafael Núñez airport (Cartagena de Indias, Colombia) were analyzed, and a linear increasing trend over time was identified. ...
Exact relativistic magnetized haloes around rotating disks
(Hindawi Publishing Corporation, 2015)
The study of the dynamics of magnetic fields in galaxies is one of important problems in formation and evolution of galaxies. In this paper, we present the exact relativistic treatment of a rotating disk surrounded by a ...
Effective Perihelion Advance and Potentials in a Conformastatic Background with Magnetic Field
(Hindawi Limited, 2016)
Exact solutions of the Einstein-Maxwell field equations for a conformastatic metric with magnetized sources are investigated. In this context, effective potentials are studied in order to understand the dynamics of the ...
