Second-order cone approximation for voltage stability analysis in direct-current networks
(2020-09-24)
In this study, the voltage stability margin for direct current (DC) networks in the presence of constant power loads is analyzed using a proposed convex mathematical reformulation. This convex model is developed by employing ...
Predictive Analysis and Data Visualization Approach for Decision Processes in Marketing Strategies: A Case of Study
(2020-10-08)
In this paper, we perform a new strategy for recommender systems in online entertainment platforms. As a case of study, we analyzed the reading preferences based on users of Goodreads, a social network for readers, to ...
Light-induced control of the spin distribution on Cu–dithiolene complexes: A correlated ab initio study
(MDPI AG, 2019)
Metal dithiolene complexes—M(dmit)2—are key building blocks for magnetic, conducting, and optical molecular materials, with singular electronic structures resulting from the mixing of the metal and dmit ligand orbitals. ...
Perchlorate-Reducing Bacteria from Hypersaline Soils of the Colombian Caribbean
(Hindawi Limited, 2019)
Perchlorate (ClO 4 - ) has several industrial applications and is frequently detected in environmental matrices at relevant concentrations to human health. Currently, perchlorate-degrading bacteria are promising strategies ...
Assessing the significance of the correlation between the components of a bivariate Gaussian random field
(John Wiley and Sons Ltd, 2015)
Assessing the significance of the correlation between the components of a bivariate random field is of great interest in the analysis of spatial data. This problem has been addressed in the literature using suitable ...
Early prediction of severe maternal morbidity using machine learning techniques
(Springer Verlag, 2016)
Severe Maternal Morbidity is a public health issue. It may occur during pregnancy, delivery, or puerperium due to conditions (hypertensive disorders, hemorrhages, infections and others) that put in risk the women’s or ...
Design of discrete event systems supported on wireless sensors and actuator networks using colored Petri Nets
(Institute of Electrical and Electronics Engineers Inc., 2015)
Manufacturing systems are highly parallel and distributed processes which require a high level of guarantee in operation and safety. Its concurrent and non-deterministic nature makes its analysis and design very complex. ...
Variational thermodynamics of relativistic thin disks
(Springer New York LLC, 2015)
We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the ...
Development and/or change of the notion of permanent object and operative causality: Empirical evidence in the frst year of life
(Fundacion para el Avance de la Psicologia, 2013)
This study examines the notion of permanent object during the first year of life, taking into account the controversy of two approaches about the nature of change: developmental change and cognitive change. Using a ...
Static secure page allocation for light-weight dynamic information flow tracking
(2012)
Dynamic information flow tracking (DIFT) is an effective security countermeasure for both low-level memory corruptions and high-level semantic attacks. However, many software approaches suffer large performance degradation, ...
