To do this, the values of acceleration of gravity will be measured analytically and graphically, and sufficient data will be taken to make different statistical calculations including standard deviations, measures of central tendency, measures of dispersion, percentile, quartile, and graphing. as histogram and ogive. The results show that the calculated values of gravity present percentage errors about the established value of gravity, and it can also be seen that statistics contribute to the calculation of physical parameters.</p> <p><strong>Keywords:</strong> Simple pendulum, acceleration of gravity, descriptive statistics, timer with sensors, Arduino.</p> Amely Valentina Cordova Cevallos Ana Maria Leon Pullas Joaquin Andres Nunez Rodrigue Copyright (c) 2022 Amely Valentina Cordova Cevallos, Ana Maria Leon Pullas, Joaquin Andres Nunez Rodrigue https://creativecommons.org/licenses/by/4.0/deed.es 2022-03-01 2022-03-01 3 7 5 17 10.47460/athenea.v3i7.32 Innovation in engineering https://athenea.autanabooks.com/index.php/revista/article/view/33 <p>New industrial trends are glimpsed on a digital panorama with a high content of scientific and technological innovation. In this work, a bibliographical evaluation is carried out to know the educational guidelines of innovation in the training of engineers. A wide spectrum of academic and scientific material, from good databases, is evaluated in order to learn about engineering programs and their impact on industrial digitization, from an innovation point of view. The results show that engineering education requires a substantial reform to adapt to the industrial demands of the new times, it also shows that in Latin America a more globalized vision is required in the training of engineers.</p> <p><strong>Keywords:</strong> Engineering education, digital companies, scientific and technological innovation.</p> Maria Gabriela Mancero Arias Copyright (c) 2022 Maria Gabriela Mancero Arias https://creativecommons.org/licenses/by/4.0/deed.es 2022-03-01 2022-03-01 3 7 18 22 10.47460/athenea.v3i7.33 Education for engineers in times of pandemic https://athenea.autanabooks.com/index.php/revista/article/view/34 <p>In this work, a bibliographical analysis of the educational situation in the time of the pandemic and its projections for the new times of the digital age is carried out. For this, academic documents from different sources of information are analyzed, mainly from recognized scientific journals. The results of the research show that university education for engineering programs was sufficiently affected by the physical distancing of universities, and the needs in technical areas were not adequately covered. These observations lead us to think that programs in the areas of technology and engineering, where laboratory practices are of great importance, should be transformed to a vision focused on industry 4.0 and where technical applications can be handled remotely.</p> <p><strong>Keywords:</strong> Engineering training, industry 4.0, virtual laboratories.</p> Cristhian Gustavo Minaya Vera Junior Antonio Briones Mera Irina Arias Vera Andres Alexander Minaya Vera Copyright (c) 2022 Cristhian Gustavo Minaya Vera, Junior Antonio Briones Mera, Irina Arias Vera, Andres Alexander Minaya Vera https://creativecommons.org/licenses/by/4.0/deed.es 2022-03-01 2022-03-01 3 7 23 29 10.47460/athenea.v3i7.34 Analytical and Theoretical Gravity Statistics https://athenea.autanabooks.com/index.php/revista/article/view/35 <p>In this work, a statistical analysis of the experimental values of gravity is carried out and they are contrasted with the existing theoretical values. To carry out the measurements, an experimental practice of the simple pendulum is carried out, which allows obtaining data in a real way. Three-time measurements were made for each length of the pendulum, thus obtaining a broad data set, which with descriptive statistics will facilitate the understanding of the analytical estimates of gravity, which will then be contrasted with the theoretical values. Finally, the results show that the percentage errors between the analytical gravity are acceptable with the theoretical values and that the study of the simple pendulum with statistical analysis is a very valuable engineering resource.</p> <p><strong>Keywords:</strong> Statistical analysis, simple pendulum, acceleration of gravity.</p> Fabiana Liria Thyara Vintimilla Jadira Estefania Vinueza Copyright (c) 2022 Fabiana Liria, Thyara Vintimilla, Jadira Estefania Vinueza https://creativecommons.org/licenses/by/4.0/deed.es 2022-03-01 2022-03-01 3 7 30 43 10.47460/athenea.v3i7.35 Chapter 3: Soil mechanics studies https://athenea.autanabooks.com/index.php/revista/article/view/36 <p>The soil analysis allows to know the physical, chemical and mechanical properties of the projected soil, that is to say, the stratigraphic composition, the layers or strata that compose the different properties of the soil and its depth, as well as the depth at which its foundations should be made.<br>It is important to recognize the type of soil, because each of them has a specific property such as gravels are very permeable, sands have high capillarity, silts are suitable for compaction and clays are impermeable.<br>Studies carried out on the soil, such as granulometry, allow it to be classified according to SUCS or AASHTO standards, moisture analysis allows the amount of water that is present together with the particles to be recognized, the stratigraphic profile allows the heights of the soil layers and their color and texture to be known, consistency limits such as liquid limit and plastic limit allow it to be recognized if they have moldable properties, the specific gravity is an important factor in its design, the content of soluble salts allows to determine the type of cement to be used, the proctor test allows to know the compaction characteristics such as dry specific weight and optimum moisture and the direct shear test allows to recognize the angle of internal friction and cohesion present in the soil. The purpose of the soil study is to provide the necessary data to carry out the designs of engineering works, to recognize the characteristics of the soil in situ, to prevent possible problems in the future, as well as to establish the appropriate modifications to the construction processes and above all to guarantee the good operation of the building and to fulfill its useful life time.</p> Sleyther Arturo De La Cruz Vega Cristian Milton Mendoza Flores Kevin Arturo Ascoy Flores Johnny Gregorio Cipriano Bautista Julio Cesar Barrenechea Alvarado Gumercindo Flores Reyes Copyright (c) 2022 Sleyther Arturo De La Cruz Vega, Cristian Milton Mendoza Flores, Kevin Arturo Ascoy Flores, Johnny Gregorio Cipriano Bautista, Julio Cesar Barrenechea Alvarado, Gumercindo Flores Reyes https://creativecommons.org/licenses/by/4.0/deed.es 2022-03-01 2022-03-01 3 7 44 62 10.47460/athenea.v3i7.36
