Effect on the demand and stock returns: cross-sectional of Big Data and time-series analysis
(Universidad de la Costa, 2019-11-05)
For reducing the degree of uncertainty caused by constant change in the environment, large, medium or small, private or public organizations must support their decisions in something more than experience or intuition; they ...
Unbalanced data processing using oversampling: machine Learning
(Corporación Universidad de la Costa, 2020)
Nowadays, the DL algorithms show good results when used in the solution of different problems which present similar characteristics as the great amount of data and high dimensionality. However, one of the main challenges ...
Classification of authors for an automatic recommendation process for criminal responsibility
(Corporación Universidad de la Costa, 2020)
One problem in classifying tasks is the handling of features that characterize classes. When the list of features is long, a noise resistant algorithm of irrelevant features can be used, or these features can be reduced. ...
Factors that describe the use of digital devices in Latin American universities
(Corporación Universidad de la Costa, 2020)
Mobile digital devices are at the same time a tool for social interaction, an individual learning resource and can be a valuable contribution in the context of higher education to develop and promote new teaching and ...
Analysis of crowd behavior through pattern virtualization
(Corporación Universidad de la Costa, 2020)
The study of the concentration of individuals in public places such as squares, shopping malls, parks, gardens, etc., is an open study field in the different disciplines of science, that leads to the need of having systems ...
Geosimulation as a tool for the prevention of traffic accidents
(Corporación Universidad de la Costa, 2021)
Traffic accidents represent a never-ending tragedy, and according to the World Health Organization (2018), 1.33 million people die in the world every year [1]. Most efforts in modeling phenomena of a dynamic nature have ...
Classification of digitized documents applying neural networks
(Universidad de la Costa, 2020-03-05)
The exponential increase of the information available in digital format during the last years and the expectations of future growth make it necessary for the organization of information in order to improve the search and ...
Analytical study of radiative casson nanoliquid flow with heat absorption
(Corporación Universidad de la Costa, 2020)
The divergence of thermally radiative MHD flow of a Casson nanofluid over a stretching paper alongside heat absorption. The governing non linear equations are remodeled into a nonlinear ODE’s. The HAM is adopted to find ...
Computational analysis of third-grade liquid flow with cross diffusion effects: application to entropy modeling
(Corporación Universidad de la Costa, 2020)
The key goal of this current study is to analyze the entropy generation with cross diffusion effects. The third-grade type non-Newtonian fluid model is used in this study. The current flow problem is modelled with stretching ...
Learning style preferences of college students using big data
(Procedia Computer Science, 2019)
Learning styles is one of the most studied topics in the field of education and the research results have generated relevant changes in the teaching-learning process. Currently, there are several theoretical models that ...
