“…This is achieved through the bibliometric analysis of articles that in their title, abstract and keywords include the term core. It begins with the definition of the type of information, in this case the primary literature is considered as the main and most important reference of knowledge in the world scientific field (Fernández, Bote, & Moya-Anegón, 2013), for its scientific contributions and for receiving most of the citations. The source of information consulted was SCOPUS as the database that mostly indexes journals and conferences proceedings (Leydesdorff, Moya-Anegón, & Guerrero, 2010).…”

“…Other studies have used bibliometrics to identify scientific publications with the highest impact in a certain discipline, for example in the field of information systems (Chan, Guness, & Kim, 2015), information science (Waltman, van Eck, & Noyons, 2010), environmental social responsibility (Valenzuela, Linares, & Suárez, 2015), renewable energy, sustainability and environment (Fernández, Bote, & Moya-Anegón, 2013), business and technical communication (Lowry, Humpherys, Malwitz, & Nix, 2007), neurosurgery (Madhugiri, Ambekar, Strom, & Nanda, 2013), among others.…”

E-learning has been continuously present in current educational discourse, thanks to technological advances, learning methodologies and public or organizational policies, among other factors. However, despite its boom and dominance in various subject areas, this thematic does not yet exist in the world system of publications. Therefore, works in this thematic end up being published under related categories, particularly Education or categories within subject area Computer Science, thus fragmenting and make invisible the existing knowledge. This work is based on the hypothesis that the scientific communication of e-learning has a sufficient degree of cohesion to be considered as a thematic category in itself. From a bibliometric approach, its scientific production was analyzed, obtaining the bibliographic data of SCOPUS and SCImago, selecting its main descriptors and generating visualizations through VOSViewer with the mapping overlay technique, to represent its set and proximity. As a result, it was determined that a set of 219 publications show a high bibliometric interrelation among its articles and these are presented transversely between the social sciences, computer science and health. This set serves as a channel of scientific communication and structure of knowledge on the thematic and can therefore be considered as the basis for establishing the "e-learning" thematic category in the world system of scientific publications, contributing to the consolidation of the discipline, to its access and development by researchers.

“…As a measure to the global issue of greenhouse gas emissions and global warming, several countries around the world [1], especially countries in development processes [2], such as India, Pakistan, Nepal, Afghanistan, and so on [3], have begun to diversify their energy matrix by incorporating renewable energy generation systems [4]. The potential for growth of these generation systems has allowed this solution to be positioned as a mature technology in the energy sector, thus attracting the interest of the European scientific community [5], which plays an essential role for the improvement of worldwide environmental indicators [6].…”

Economic and Environmental Multiobjective Optimization of a Wind–Solar–Fuel Cell Hybrid Energy System in the Colombian Caribbean Region

A hybrid system was analyzed and optimized to produce electric energy in non-interconnected zones in the Colombian Caribbean region, contributing to the reduction of greenhouse gas emissions and the improvement in efficient energy management. A comparative analysis of the performance of hybrid was conducted using a proposed model, built with historical data for meteorological conditions, wind speed, and solar radiation. The model is integrated by a Southwest Wind Power Inc. wind turbine AIR 403, a proton-exchange membrane fuel cell (PEM), an electrolyzer, a solar panel, and a regulator based on proportional, integral, and derivative (PID) controllers to manipulate oxygen and hydrogen flow entering in the fuel cell. The transient responses of the cell voltage, current, and power were obtained for the demand of 200 W under changes in solar radiation and wind speed for each day of the year 2013 in different meteorological stations, such as Ernesto Cortissoz airport, Puerto Bolívar, Alfonso Lopez airport, and Simon Bolívar airport. Through the adjustment of the hydrogen and oxygen flow into the fuel cell, the maximum contribution of power generation from the fuel cell was presented for the Simon Bolívar airport in November with a value of 158.35 W (9.45%). Multiobjective design optimization under a Pareto diagram front is presented for each place studied to minimize the levelized cost of energy and CO2 emission, where the objective control variables are the number of panel and stack in the photovoltaic (PV) system and PEM.

“…The bibliometric data are very valuable to identify the scientific publications with the greatest impact in a given discipline, (i.e., Information Systems [1], Renewable Energy, Sustainability and Environment [2], to recognize different scientific fields and understand their internal dynamics and cognitive structure [3], either as an already consolidated research field or as an emerging discipline.…”

The mapping overlay technique described in the scientific literature to analyze scientific domains must be complemented with procedures to identify and analyze the research fronts included in the cognitive structure of the represented domain. One possibility is the use of wordcloud maps to visually represent the cognitive structure of a discipline in any thematic domain, taking advantage of its capacity for abstraction and impact on the audience to stimulate new research processes. The case described in this chapter proposes an analysis of an emerging scientific discipline by using this combination of techniques (superposition and wordcloud) to explore its possibilities and limitations.
