Development of random thinking: Reflections and considerations
(IOP Publishing, 2020)
This article discloses some considerations and reflections in the teaching of random thinking and data systems based on a documentary review. A documentary sample was used consisting of 40 documentary sources (articles, postgraduate dissertations and books), published in indexed journals, about random thinking. The research was based on a qualitative content analysis method which used the coding and categories saturation process. The results let us establish conceptual relationships considering three dimensions linked to the random thinking ...
Security strategy for vulnerabilities prevention in the development of web applications
(IOP Publishing, 2019)
In recent years, Higher Education Institutions through their Systems departments have
strengthened security for the development of applications on web environment, because of their
vulnerability to possible computer attacks. This research proposes a security strategy to reduce
the risk presented by the web applications developed in the systems department of the Simón
Bolívar University, in San José de Cúcuta, Colombia, based on a diagnosis of the current state
of its security policy compared to other institutions of the department of Norte ...
New anisotropic diffusion operator in images filtering
(IOP Publishing, 2020)
The anisotropic di usion lters have become in the fundamental bases to address
the medical images noise problem. The main attributes of these lters are: the noise removal
e ectiveness and the preservation of the information belonging to the edges that delimit the
objects of an image. Due to these excellent attributes, through this article, a comparative study
is proposed between a new di usion operator and the Lorentz operator, proposed by the pioneers
of anisotropic di usion. For this, a strategy consisting of two phases is designed. In ...
Parallel methods for linear systems solution in extreme learning machines: an overview
(2020)
This paper aims to present an updated review of parallel algorithms for solving
square and rectangular single and double precision matrix linear systems using multi-core central
processing units and graphic processing units. A brief description of the methods for the solution
of linear systems based on operations, factorization and iterations was made. The methodology
implemented, in this article, is a documentary and it was based on the review of about 17
papers reported in the literature during the last five years (2016-2020). The disclosed ...
