“…Therefore, extraction of resistive component from total measured leakage current is very important to get the correct power loss. In this article, Current Orthogonality Method (COM), which is accurate and robust method to the harmonic voltage, has been used for resistive leakage current extraction . Based on experimental measuring, power loss has been obtained from extracted resistive component and applied voltage for one cycle according to the equation (1).…”

“…Nevertheless, the variation of time to crest and also amplitude of voltage and current impulses can be changed V – I characteristic. Temporary and long duration over‐voltages, switching, lightning, and steep current impulses are the examples of slow and fast front wave with different time to crest from several millisecond to 1 μs . In order to obtain V – I characteristic in high current region, 120 kJ—1.2 MV Marx generator has been used to product impulse current with different time to crest and amplitude.…”

Analysis of electro‐thermal behavior in various operating condition based on finite element method was proposed in this article. Power frequency and impulse stresses vary the operating region and temperature of surge arresters. Therefore, adaptive power loss was considered as a source in the modeling of surge arrester based on finite element method. Adaptive network based fuzzy inference system and frequency dependent model were used to model power loss in low and high current regions, respectively. To obtain accurate power loss, which is very important factor in electro‐thermal analysis, applied voltage and temperature were considered as inputs in adaptive network based fuzzy inference system model. The experimental setup including impulse generator, power frequency high voltage generator and also an oven was arranged to achieve real data. Finally, the results of simulation based on proposed adaptive method were compared with the thermal infrared camera results. This study shows that the electro‐thermal behavior of surge arrester is predictable with a good accuracy by using artificial model. © 2015 Wiley Periodicals, Inc.

“…It means that the evolution of the learning process has created the need to use additional academic tools that are linked with the state of the art of technology. The creation and use of a different kind of software in all areas of knowledge [8][9][10][11][12][13][14] has been a solution to this problem. The new generation of students was born in a digital era [15] where computers dominate over the books.…”

This article presents the application of a new educational thermodynamic software called MOLECULARDISORDER, based on graphical user interfaces created in Matlab ® to promote critical thinking in youth engineering students, by means of the energy and entropy balance application in different systems. Statistics of the results obtained by the youth students are shown to determine the influence of the software in a regular course in thermodynamics to promote critical thinking. Two case studies were done by the students, where parameters such as temperature of the fluid and metal surfaces, pressure of the system, mass of the fluid and solid, volume, and velocity of the fluid are used to obtain output variables such as enthalpy, entropy, changes in entropy, entropy production, and energy transfer in the chosen system. Four cognitive skills were considered to evaluate the cognitive competencies of interpreting, arguing and proposing, and interacting with the different graphical user interfaces; these cognitive skills (CS) were argumentative claim (CS1), modeling (CS2), interpreting data/information (CS3), and organization (CS4). Student´s T-test was used to compare the degree of difficulty of each criterion. The case studies were evaluated first without using the software and then with the use of the software to determine the significant effect of the software quantitatively. A population of 130 youth students was taken to perform the statistical analysis with a level of significance of 5%. With the help of the software, the students obtained an improvement when performing case study 1 since the p-value obtained was 0.03, indicating that there are significant differences between the results before and after taking the software. The overall averages of the grades for case study 1 had an increase after using the software from 3.74 to 4.04. The overall averages for case study 2 were also higher after taking the software from 3.44 to 3.75.

“…Ramos et al presented an e‐assessment of MATLAB assignments in Moodle (i.e., an open‐source community‐based tools for learning, https://moodle.org), with an application to programming course for engineers. Different studies concerning with the teaching–learning process in Engineering using MATLAB or MATLAB‐Simulink can be found in a literature survey (, among others). Soria‐Olivas et al described an introductory course to MATLAB for a heterogeneous group of university students; they pointed out that students attending that course discovered that a tool employed in their own field, could also be successfully applied to other fields.…”

This paper presents a procedure for the improvement of the reflective learning in Engineering, including the use of MATLAB for problems solving. Three effects are produced in students. The first, the searching of the solution of a particular case is substituted by the modeling of the general problem. The second, a reflection on their theoretical knowledge is encouraged. The third, the motivation for an autonomous learning of MATLAB is increased, taking into account the clear interest of this tool in the teaching-learning in Engineering. Lastly, several benchmark problems are presented and discussed. ß 2016 Wiley Periodicals, Inc. Comput Appl Eng Educ 24:755-764, 2016; View this article online at wileyonlinelibrary.com/journal/cae;
