Gravity process foundry simulation

In this work, they going to use a foundry simulation software to compare the virtual vs real results and try to reduce the time of the real process in the foundry area. In the real process they work with the re-engineering process of the pistons, first they take the original element and take the physical properties (length, width, thicknesses, etc.), after make a cast design and is assigned some parameters for the process, planning the process to make a test, after the casting process it goes to the machining process and finally the final inspection says if all the process during the tests is correct, if not, we need to take others parameters or casting design. With this project is going to be possible to save time in the foundry area and make a virtual process to see the result and change all the necessary things to have a perfect process.

Computational simulation a system of waterborne polyurethane matrix by β-C induction with ZnO and CaCO3 particles

This work includes the search for the development of a composite of a WPU (waterborne polyurethane), β-CD (β-Cyclodextrin), PZnO (zinc oxide particles), and the presence of CaCO3, to obtain new properties such as adhesion to multiple substrates of organic and inorganic origin. Therefore, a development sequence was proposed: Computational development: conformation of the polymeric matrix (with the intermediary polymers) and simulation of the interaction between β-CD and PZnO and Ca+2 and CO3-2 ions, as well as insertions in β-CD, computational simulations were carried out with the help of ACD LABS™ (free version) software and by molecular dynamics with GROMACS™. With the above, we were able to determine properties such as interfacial tensions, surface tensions, and contact angles, and degrees of solvation and stability in waterborne emulsions. Therefore, it is important to point out that one of the main contributions of this research proposal is that there are no studies that combine these materials.

Control robusto de la actitud para el seguimiento de trayectoria de un VANT

This paper proposes a robust attitude tracking control applied to Vertical Take-off and Landing Micro Aerial Vehicles (VANT) based on Active Disturbance Rejection Control (ADRC) approach. The proposed technique groups the endogenous and exogenous disturbances into a total disturbance, which is estimated online via extended state observer (ESO). Once the disturbance is determined, a quaternion-based controller is proposed, which compensates and relieves the disturbance actively. The control law is bounded; consequently, it takes into account the maximum capabilities of the actuators. The stability proof of the closed-loop (observer and control) is guaranteed in the ISS sense. The simulation results allow validating the theoretical features.

Sistema de información para la caracterización de imágenes de desgaste en álabes de rotor de una turbina de gas

In Mexico, the end user of gas turbines (PEMEX), in the NRF standard, requests the Goodman and Campbell diagrams for the acquisition of new turbo machinery. However, the requirement of the diagrams is not reported when the turbine is sent for overhaul. In this research article, it is suggested that the end user when carrying out a wear analysis of a turbine blade, know precisely the conditions of a blade in case of total loss of the machine or in conditions in which they send one or several turbine discs to the manufacturer and the conditions that receives after overhaul the discs. Wear and friction are the most adverse factors in reducing the useful life of mechanical equipment. The loss of a relatively small amount of material, in certain critical locations of any mechanical part, can make the difference between the damage and the good functioning of the gas turbine, so this research aims to characterize images of a turbine blade with in order to identify any wear or mechanical failure; analyzing the responses to deterministic and non-deterministic variables, looking for responses that contribute to the early detection of any mechanical failure that prevents the total loss of the gas turbine in operation. To achieve the objectives set out in this research, techniques and tools with a systemic and systematic approach are used, which will allow the characterization and interpretation of images of gas turbine blades.

La incorporación de tecnologías emergentes en la formación de alumnos del área económico-administrativo

The present work is focused on proposing the incorporation of Emerging Technologies (ET) in the Economic-Administrative area (EAA), specifically for students of the Bachelor's Degree in Accounting (LCN, Spanish acronym) and the Bachelor's Degree in Administrative Informatics (LIA, Spanish acronym), of the Chalco Valley University Center of the UAEMex, because they are focused on the development and creation of businesses, starting with the use of mobile phones, augmented reality and virtual supports. An instrument with a Likert scale elaborated, applied to a sample of 238 students of LIA and LCN, taking the total of students as population (408) and a convenience sampling was carried out. Also, there was an interview with 12 professors of both bachelor's degrees. The focus considered in the research was qualitative, transversal, and field. The questionnaire validated with Cronbach's alpha (0.81) and its score applying the mean and standard deviation, coding each of the items according to the characteristics of the study population. Among the results, teachers agreed to incorporate emerging technologies and to design how they will implement them in the classroom so that the proposed strategies contribute to the learning of students in the economic-administrative area.

Aplicación Web para Niños con Problemas de Dicción

The web application for children with diction problems, seeks to contribute to the reduction of a pronunciation problem known as dyslalia. The application can be used on any device connected to the internet, its main purpose is through exercises and dynamics integrated in it, improve the diction that children present in the range of 4 to 6 years of age. The methodology used is the development of iterations that allows reducing the risk that arises between the needs of the user and the final product due to misunderstandings during the requirements collection stage; having the advantage of carrying out the development in small cycles, allowing to better manage risks and deliveries. The web application for children with diction problems, in its first version, has had good results, highlighting its functionality and application, which has shown great acceptance by children, educators, experts and even parents, but about all because in the period of use of a month have begun to have improvements in the pronunciation of users (boys and girls).

Tecnología móvil en el ambiente académico y su uso en videojuegos

The use of mobile devices among the young population has become widespread, to read newspapers, books or magazines, find information for school assignments, and communicate with their peers for student activities, which can be used to motivate better academic performance. New applications and platforms for learning management, related to new technologies, increasingly accessible such as mobile, with smartphones or tablets in the classroom, forces teachers to use these advantages in their teaching and learning strategies. This paper presents a study, at the National Technological Institute of Mexico, on how the use of this mobile technology is correlated with better results in academic performance for engineering students in mathematics and written language, not so for physics. So also, how the widespread use of social networks and applications for leisure, such as video games, can become a strategic motivational element for learning. The study also shows the need to strengthen the commitment of teachers to link these technologies effectively in the classroom, and not leave it in an intentionality.
