Ajustar las condiciones de operación de una prensa hidráulica horizontal de fabricación propia para un proceso de doblado en frío a 90°

Hugo Estrada Pimentel HUGO ARCOS GUTIERREZ JOSE ANTONIO BETANCOURT CANTERA Jan Mayén Chaires John Edison García Herrera (2023, [Artículo])

During the cold-bending process, the tooling suffers considerable damage due to excess pressure. This also causes the machines to break down, causing problems in the precision and quality of the metal parts formed. The precision depends on the operating conditions of the press, the tooling employed, and the elastic recovery effect of the material. This study determines the working conditions for a made-in-house horizontal hydraulic press through an experimental design (DOE). This research carried out the V-forming to 90° (ISO 2768-1) of a hot-rolled carbon steel plate, considering pressure, piston permanence time, and recovery factor (Kr). The experimental and statistical analysis ensures accurate forming while the work pressure decreases by 17% and 33%, respectively, regarding the maximum. This reduction will delay the appearance of fatigue damage and have the operating parameters well established; in turn, it will be possible to design tools according to commercial standards.

Durante el proceso de conformado en frío, las herramientas sufren daños considerables debido al exceso de presión. Esto también causa que las máquinas se rompan, causando problemas en la precisión y calidad de las piezas metálicas formadas. La precisión depende de las condiciones de funcionamiento de la prensa, las herramientas empleadas y el efecto elástico de recuperación del material. Este estudio determina las condiciones de trabajo de una prensa hidráulica horizontal fabricado en casa a través de un diseño experimental (DOE). Esta investigación llevó a cabo el conformado en V a 90° (ISO 2768-1) de una placa de acero al carbono laminada en caliente, teniendo en cuenta la presión, el tiempo de permanencia del pistón y el factor de recuperación (Kr). El análisis experimental y estadístico asegura un conformado preciso, mientras que la presión de trabajo disminuyó en un 17% y 33%, respectivamente, con respecto al máximo. Esta reducción retrasará la aparición de daños por fatiga y tendrá los parámetros de funcionamiento bien establecidos; con estos, a su vez, será posible diseñar herramientas de acuerdo con los estándares comerciales.

A twelve years story of waste of social resources: The Mexico-Toluca Interurban Train

Rubén Chavarín (2024, [Artículo, Artículo])

The general objective of this paper is to make an ex-post evaluation of the Mexico-Toluca Interurban Train project (TIMT) more than nine years after the beginning of its construction stage. The present study is based on the cost-benefit analysis approach, through which some analysis scenarios have been built and whose results are contrasted with the official project evaluations. The present research has focused on the analysis of the TIMT as a microcosm of the scarce efficiency of public investment in Mexico, resulting in a waste of social resources. According to the results of the study, the combination of delays and cost overruns (186% in nominal terms, 114% in real terms, and 90% in dollars) has configured a project (across two Federal Government Administrations) with negative social profitability, with losses valued at more than 550 million dollars, placing it in the most problematic quartile of train projects in the world.

Sentido y significación del habla en la actuación

Claudia Fragoso Susunaga (2023, [Capítulo de libro])

Capítulo número 2 de la Sección El juego de los signos.

El objetivo de este texto es identificar los elementos de los actos de habla y la pragmática lingüística, que tienen que ver con procesos de significación e intención en la enunciación de un texto dramático-escénico o de algún personaje, pensando en las actividades de doblaje, radio-drama, videojuegos, audiolibros y la escena misma. Desarrollando, desde una visión transdisciplinaria la interacción de diferentes campos del conocimiento, como lo son el teatro, la semiótica y la lingüística e incluso todas aquellas disciplinas humanas que comprenden el habla y su interés en los procesos de comunicación. Las repercusiones de este análisis pueden recaer directamente en la formación y desempeño actoral, favoreciendo procesos de análisis de texto, en función a un enriquecimiento de la expresión comunicativa de actores y actrices.

Geospatial analysis of the distribution of empty spaces located in Nuevo Laredo, Tamaulipas

Claudio Curzio HECTOR DE LA TORRE GUTIERREZ (2021, [Artículo, Artículo])

Reflect about urban empty spaces means looking around all these lots that are distributed in different geographical points of the cities and are characterized because they are still waiting to be built, therefore, they are vacant, and also these spaces are empty in the sense of not provide any function. In this sense, the objective of this article is to present a methodological proposal specially designed to study this type of urban elements from the particular point of view of urban geography and spatial analysis. Specifically, through a series of surveys, both digital and physical, the various urban voids located in the city of Nuevo Laredo were recorded, thereby creating a database that included a total of 3,836 case studies. In this way, using different types of statistical techniques and spatial models, it was possible to obtain and interpret the results, managing to identify exactly what were the main patterns and characteristics of said geographic distribution.

Efficiency of combating property violence in the Northwest region of Mexico

Martin Flegl Eva Selene Hernández Gress (2023, [Artículo, Artículo])

The situation of violence in Mexico shows an alarming trend as the number of committed crimes increased by 10.9% in 2021 compared to 2020. In fact, 75.6% of the Mexican population perceives the insecurity. Due to the above, it is necessary to strengthen public security to combat this trend. However, the resources allocated to the public security in Mexico are limited. Although there are studies that investigate what causes the violence in Mexico, so far there is no study that measures the efficiency of combating the violence related to budgetary, human, and material resources of the public security. This article investigates the efficiency of combating the property violence in 206 municipalities in the Northwest region of Mexico through the Data Envelopment Analysis. The results show a low efficiency (56.67%) with significant differences between the states in the region. Baja California is the state with the lowest efficiency (17.61%), whereas the highest efficiency is found in Durango (67.25%). For the last, the need to carefully plan changes in the police force and the public security infrastructure was noted to improve the efficiency and the level of security.
