This article provides an estimation of the future demand of construction materials in Colombia and necessary minerals to produce them by using systems dynamic and analysis of materials flows. Through the analysis of materials flows the amount of minerals required for the production of cement and concrete are determined. Required production of cement and concrete is estimated through a model of systems dynamic, which is adjusted with data from DANE construction census. Results indicate that, disregarding the secondary offer of materials, 176.9 million tons of ground aggregates, river sand, gray cement, dead rock, and cooked ceramic would be required. Manufacture of cement and concrete would require 15.4 million tons of lime, 14.9 million tons of gravel, 14.1 million tons of gypsum, and 13.3, 9.7, and 9.3 million tons of clay, iron minerals, and sand, respectively.

The inhibition efficiency of corrosion of the extract of neem leaves (Azadirachta indica) on carbon steel and aluminum was evaluated in contact with a sodium chloride and sodium sulfate solution, both at 3.5% p/v. Corrosion speed was determined and it was found that the Neem extract, at a lower concentration, reached better efficiencies on carbon steel in sodium chloride with 78% efficiency using 5% of the extract; concerning the aluminum, the efficiency values reached were low. Besides, through the adjustment to the Langmuir’s isotherms, it was possible to determine that the nem extract was adsorbed spontaneously on the surface of carbon steel and allowed to delay the corrosive process when reaching inhibition efficiencies of 90%. Results of this research allow establishing that the neem extract has a high potential as corrosion inhibitor to be applied in the industry as corrosion preventive medium.

Gamification is shown as an alternative for traditional classroom strategies and is increasingly used in higher education. The purpose of the revision is to know the way gamification has brought more interest in the following fields of knowledge in terms of bibliographic production and use: management and economics, arts and humanities, health sciences, natural and exact sciences, social and juridical sciences, engineering, and architecture. Participation was identified according to results in nine academic databases. The field with the highest percentage, based on the scale defined in the methodology, is Engineering and Architecture (3.15), while health sciences obtained 0.49. It is clearly seen that gamification is a field explored in higher education and experiences which have generated its application are different. Setting usage guidelines is recommended, including studies of a bigger scope in order to know its real effects on the learning process.

This article shows a methodology for the technical and economic analysis of the incorporation of Facts devices in electrical power systems. The methodology proposed consists of a deterministic stage and a stochastic stage which involve aspects of technical and economic feasibility, respectively. The first stage is based on a non-linear binary mixed programming model developed at AMPL in order to minimize generation of safety given the location of a Facts device. The second stage employs an energetic model based on a stochastic dynamic dual programming (SDDP) which determines the cost-benefit ratios of the incorporation of Facts for different hydrothermal series. In order to illustrate the applicability of the methodology proposed, a case study is shown in the Colombian electrical system, taking into account the incorporation of a Statcom in the Atlantic Coast. Additionally, it is shown that the solution proposed resolves oscillatory instability problems of power, identified in minimum generation scenarios before critical contingencies.

This article is intended to develop and validate a green distribution center model consisting of three components: a management module; a warehouse management system (WMS); and a metaheuristics. As a result of the validation of the model at a Distribution Center of a medium-size food company, a reduction of CO 2 emissions was achieved, equivalent to 731 kg/month or 37% of issues for preparation of orders. Additionally, the modeling of a Taboo Search metaheuristics was developed to resolve the routing problem for the preparation of orders; this allowed increasing the operation efficiency in about 18.83% and to obtain a reduction of 198 kg of equivalent CO 2 per month. Therefore, the green distribution center model, simultaneously, increased the efficiency and reduced the amount of kilograms of CO 2 , using an approach that had not been addressed in literature for this logistic process.

This article is the result of a research. It proposes a reference framework for using the Canvas Business Model in conjunction with the Solutions Construction Model for the development of telematics systems. By using the CBM and its translation for the modeling of UML-based business and the Rational Unified Process (RUP) guidelines, understanding process of the organizational context where the solution will operate and dialogue between the interested parties becomes easier. Optionally, the use of the Minimum Viable Product (MVP) is proposed, as defined in the Lean Startup, as complement to the idea of operating the solution scenario before going forward to the construction stages. The reference framework was tested with the development of a telematics solution for the Scho ol of Health Sciences of Universidad del Cauca, showing its advantages and facilitating developers and customers a better understanding of the organizational context and the evolution and definition of the solution to be constructed.

Para aportar al desarrollo de estos proyectos, se propone una metodologia para desarrollar proyectos de mineria multimedia llamada Metodologia de Analitica Multimedia (MAM). Asi mismo, se presenta la construccion de una herramienta software que permite el analisis de mineria multimedia llamada Plataforma de Analitica Multimedia (PAM). La metodologia y la plataforma son evaluadas con dos casos de estudio sobre prediccion de anormalidades en mamografias y analisis de similaridad en imagenologia medica. Los resultados obtenidos permitieron validar los pasos propuestos en la metodologia MAM y utilizar la plataforma PAM para extraer las caracteristicas de las imagenes medicas, aplicar tecnicas de mineria de datos y evaluar satisfactoriamente los resultados obtenidos.
