Parámetros medioambientales de sustentabilidad como base para la toma de decisiones económicas en Ciudad Juárez
(2018-05-08)El enfoque convencional examina el proceso económico como un sistema aislado del entorno social y medioambiental, donde sólo tienen cabida aquellas cosas que previamente han sido valoradas monetariamente y donde todo lo ... -
Paso del Norte: La competencia por las aguas subterráneas fronterizas
(2018-01-08)Con el advenimiento del capitalismo, entre otros acontecimientos, los ríos, lagos y/o lagunas se convirtieron en fronteras entre los países bajo el naciente concepto de estado-nación. Este fue el caso de los ríos Bravo/Grande ... -
Patrones de concentración de carbono negro y principales fuentes de emisión en Ciudad Juárez, Chihuahua, México
(2020-06-27)El carbono negro (CN) es un contaminante atmosférico producido de forma natural y como resultado de la combustión incompleta de combustibles fósiles, biocombustibles y biomasa. La región Paso del Norte (México-Estados ... -
Phase transformation and magnetocaloric effect of Co-doped Mn–Ni–In melt-spun ribbons
(2020-08-06)Ribbon-shaped magnetocaloric materials are favorable to achieve high heat-transfer efficiencies due to their large specific surface area. In this work, Mn50Ni41−xIn9Cox (0 ≤ x ≤ 4) ribbons were prepared using a melt-spinning ... -
Phase transition and magnetocaloric properties of Mn50Ni42-xCoxSn8 (0 < x < 10) melt-spun ribbons
(2018-01-01)The characteristics of magnetostructural coupling play a crucial role in the magnetic field-driven behaviour of magnetofunctional alloys. The availability of magnetostructural coupling over a broad temperature range is of ... -
Physicochemical properties of chitosan–magnetite nanocomposites obtained with different pH
(2021-08-10)The physicochemical properties of the nanoparticle surface determine the performance of nanocomposites in biomedical applications such as their biodistribution and pharmacokinetics. The physicochemical properties of chitosan, ... -
Pre-twisted calculus and differential equations
(2023-07-10)In this paper we introduce the φA-differentiability for functions f:U⊂R^k→R^n, where U is an open set, A is the linear space R^n endowed with a unital associative commutative algebra product, and φ:U⊂R^k→A is a differentiable ... -
Predicting airline customer satisfaction using k-nn ensemble regression models
(2019)Customer satisfaction questionnaires are a rich and strong source of information for companies to seek loyalty, customer and client retention, opti- mize resources, and repurchase products. Several advanced machine learning ... -
Project portfolio selection with scheduling: an evolutionary approach
(2019)This paper addresses the project portfolio selection problem enriched with scheduling. Thefactors considered for project scheduling are: the planning time horizon and the negative impact of theproject completion time on ... -
Promoting green infrastructure in Mexico's northern border: The Border Environment Cooperation Commission's experience and lessons learned
(2019-01-01)This paper describes the application of a comprehensive strategic approach for integrating Green Infrastructure (GI) in urban planning in Mexican communities along the U.S-Mexico border as a means to mitigate the environmental, ... -
Propuesta para el entendimiento conceptual del tiro parabólico en base a la realidad aumentada Parte I
(2018-12)La mayoría de los estudiantes de los cursos introductorios de física muestran problemas de entendimiento conceptual. Algunas de las posibles causas son: 1) la enseñanza tradicional, 2) la poca versatilidad por parte del ... -
Propuesta para el entendimiento conceptual del tiro parabólico en base a la realidad aumentada Parte II
(2018-12)Most of students from the introductory physics courses show conceptual understanding problems. One possible cause is the conventional instruction. This teaching style is based on a lack of cognitive interaction between ... -
Quasinormal modes of the Hayward black hole surrounded by quintessence: Scalar, electromagnetic and gravitational perturbations
(2022-04-20)In this paper, we study the quasinormal modes for scalar, electromagnetic, and gravita- tional axial perturbations in the Hayward regular black hole surrounded by quintessence (HBH-ωq). Using the third-order WKB approximation, ... -
Reducing The Effective Dose of Cisplatin Using Gold Nanoparticles as Carriers
(2020-03-30)Nanotechnology is a frequent treatment for cancer. Nanomaterials are the vehicles which deliver drugs in smaller but equally effective quantities. The aim of this investigation is to synthesize gold nanoparticles, functionalize ... -
Robust weighted Gaussian processes
(2020-07-09)This paper presents robust weighted variants of batch and online standard Gaussian processes (GPs) to effectively reduce the negative impact of outliers in the corresponding GP models. This is done by introducing robust ... -
Robustness analysis of an outranking model parameters’ elicitation method in the presence of noisy examples
(2018-01-03)One of the main concerns in Multicriteria Decision Aid (MCDA) is robustness analysis. Some of the most important approaches to model decision maker preferences are based on fuzzy outranking models whose parameters (e.g., ... -
Seasonal carryover of water and effects on carbon dynamics in a dryland ecosystem
(2022-07-19)Net primary productivity in arid and semiarid regions is controlled by water availability for which rainfall has been a commonly used proxy at annual scales. However, the hydrological partitioning occurring through the ... -
