The article discusses the possibility of preparing schoolchildren for the study of the basics of engineering in the framework of training in the section "Algorithmization and programming" of the informatics course based on the Arduino platform. Such training can be organized by including in the material under study practical work on the creation of electronic controlled devices: a weather station, a "smart" night light, a traffic light, a music box, etc. A simple assembly system allows using the Arduino kit for 40-minute lessons: 10 to 20 minutes depending on the complexity of the project. Also, in the classroom, it is proposed to use Tinkercad, a free 3D modeling program that allows you to assemble an electronic device online, write a code, test it, make sure it works, and download a sketch code for further use. The article presents a methodology for carrying out work in the 10th grade to create a "music box" device in Arduino. The purpose of this work is to generalize and systematize the topic "One-dimensional arrays of integers". The practical part of the lesson involves working with light, sound, control, and rotation of the figure. Thus, the concept of "array", algorithmic structures "loop" and "branching" are repeated. This work can also be carried out as an extracurricular event, for example, within the framework of a subject week.

History Of

This article shows the geometric modeling and virtual reconstruction of the optical telegraph by Agustín de Betancourt and Abraham Louis Breguet developed at the end of the 18th century. Autodesk Inventor Professional software has been used to obtain the three-dimensional (3D) model of this historical invention and its geometric documentation. The material for the research is available on the website of the Betancourt Project of the Canary Orotava Foundation for the History of Science. Thanks to the three-dimensional modeling performed, it has been possible to explain in detail both its operation and the assembly system of this invention in a coherent way. After carrying out its 3D modeling and functional analysis, it was discovered that the transmissions in the telegraph were not performed by hemp ropes but rather by metal chains with flat links, considerably reducing possible error. Similarly, it has also been found that the use of the gimbal joint facilitated the adaptability of the invention to geographical areas where there was a physical impediment to the alignment of telegraph stations. In addition, it was not now necessary for the telescope frames to be located parallel to the mast frame (frame of the indicator arrow) and therefore they could work in different planes.

Investigating the charge transport behavior in one-dimensional quantum confined system such as the localized states and interference effects due to the nanoscale grain boundaries and merged domains in wide chemical vapor deposition graphene constriction is highly desirable since it would help to realize industrial graphene-based electronic device applications. Our data suggests a crossover from interference coherent transport to carriers flushing into grain boundaries and merged domains when increasing the current. Moreover, many-body fermionic carriers with disordered system in our case can be statistically described by mean-field Gross-Pitaevskii equation via a single wave function by means of the quantum hydrodynamic approximation. The novel numerical simulation method supports the experimental results and suggests that the extreme high barrier potential regions on graphene from the grain boundaries and merged domains can be strongly affected by additional hot charges. Such interesting results could pave the way for quantum transport device by supplying additional hot current to flood into the grain boundaries and merged domains in one-dimensional quantum confined CVD graphene, a great advantage for developing graphene-based coherent electronic devices.

This article presents a methodology for the design of Grid-tie photovoltaic systems using computational tools for 3D modeling, in order to have a clearer vision of installation and with the purpose of acquiring the detailed material of what is required to have a more successful initial investment for a project. As a methodological test, a solar power plant is designed on the buildings of the Faculty of Electromechanical Engineering in Manzanillo Colima. For this purpose, the Sketchup and Helioscope softwares are used to obtain the installed capacity of the buildings, selecting the solar modules, inverters and the quantity in meters of accessories such as cable, pipe, etc. SolidWorks is used to design the assembly system and obtain the amount of material with screws included and thus make a much more accurate calculation of the initial investment required.

In this study, it is aimed to introduce such a one-dimensional traffic model to investigate two-dimensional crossing traffic flow at crossroad that without traffic light. The full velocity difference model is modified to adaptive stop by referring stopping sight distance and to solve conflict at crossroad by integrating self-organized rules. Simulation of crossing traffic flow is conducted and discussed. Results such as flow rate, individual velocity and traveling time show the crossroad without traffic light has significant impact on traffic flow. It is hoped this work may provide valuable evacuation references for the emergency department and individual evacuees.
