Mathematical problem-solving in early school years with Bee-bot
2018
Los entornos relacionados con la robótica y los lenguajes visuales de programación por bloques permiten plantear tareas que pueden ser entendidas como problemas con contenido matemático aptos para edades escolares tempranas. Estos entornos permiten proponer situaciones problemáticas en edades en las que el formalismo o el escaso conocimiento matemático impide a los estudiantes abordar problemas matemáticos más complejos. En este trabajo se da cuenta de cómo el robot programable Bee-bot constituye un dispositivo privilegiado donde poder observar cómo los estudiantes toman decisiones durante el proceso de resolución. The environments related to robotics and the visual block-based programming …
Modified locally weighted—Partial least squares regression improving clinical predictions from infrared spectra of human serum samples
2012
Locally weighted partial least squares regression (LW-PLSR) has been applied to the determination of four clinical parameters in human serum samples (total protein, triglyceride, glucose and urea contents) by Fourier transform infrared (FTIR) spectroscopy. Classical LW-PLSR models were constructed using different spectral regions. For the selection of parameters by LW-PLSR modeling, a multi-parametric study was carried out employing the minimum root-mean square error of cross validation (RMSCV) as objective function. In order to overcome the effect of strong matrix interferences on the predictive accuracy of LW-PLSR models, this work focuses on sample selection. Accordingly, a novel strateg…
Total and Subtypes of Dietary Fat Intake and its Association with Components of the Metabolic Syndrome in a Mediterranean Population at High Cardiova…
2019
Background: The effect of dietary fat intake on the metabolic syndrome (MetS) and in turn on cardiovascular disease (CVD) remains unclear in individuals at high CVD risk. Objective: To assess the association between fat intake and MetS components in an adult Mediterranean population at high CVD risk. Design: Baseline assessment of nutritional adequacy in participants (n = 6560, men and women, 55&ndash

Processing of rock core microtomography images: Using seven different machine learning algorithms
2016
The abilities of machine learning algorithms to process X-ray microtomographic rock images were determined. The study focused on the use of unsupervised, supervised, and ensemble clustering techniques, to segment X-ray computer microtomography rock images and to estimate the pore spaces and pore size diameters in the rocks. The unsupervised k-means technique gave the fastest processing time and the supervised least squares support vector machine technique gave the slowest processing time. Multiphase assemblages of solid phases (minerals and finely grained minerals) and the pore phase were found on visual inspection of the images. In general, the accuracy in terms of porosity values and pore…
Demographic Analysis of Bucharest-Ilfov Region
2013
Abstract This paper aims to achieve a study was to research, analyze and interpret statistical data, in conjunction with theoretical aspects that allowed assessment of regional information on population structure in the Bucharest-Ilfov. Bucharest-Ilfov region's population (2,264,865 inhabitants in 2012) is distributed inversely proportional to the size of two administrative entities (Bucharest - the capital of Romania - Ilfov county). Bucharest is the largest urban agglomeration in Romania, its population being 1,924,299 inhabitants, representing about 85% population of the region, more than 16.4% of the urban population of the country, or around 9% of the total population of Romania and ha…

Efectos del desarrollo sostenible percibido por el consumidor. Una propuesta de modelo de hipermercados en Ecuador
2020
Resumen El objetivo de este trabajo fue analizar la incidencia del desarrollo sostenible sobre la cadena de efectos: valor percibido - capital de marca - lealtad. Para ello, se propone un modelo teórico de relaciones que se contrasta a partir de una muestra de 317 clientes de hiper mercados en Ecuador. Los resultados, aplicando una metodología exploratoria y confirmatoria, combinada con regresión por mínimos cuadrados parciales, mostraron que tanto las acciones de desarrollo sostenible como el valor percibido son pilares maestros sobre los que se puede apoyar la estrategia minorista. Ambas se muestran como variables clave por su naturaleza, en cuanto son multidimensio nales, y por su alcanc…
