El haiku, desde José Juan Tablada, se ha transculturalizado a las formas de la lírica hispánica, de tal manera que se puede apreciar, por ejemplo, el uso de rimas, de tropos clásicos de la retórica o una enunciación del yo lírico en devaneos elegiacos, celebratorios, filosóficos, etc. Sin embargo, el poeta mexicano, Jorge Tenorio, ha buscado acercarse al haiku, no desde la propia retórica hispánica a la que pertenece, evitando rimas, metáforas u otros tropos afines a la tradición iniciada por José Juan Tablada, sino a través de la idea del vacío del budismo zen, que tiene como consecuencia en la conformación del poemario Hondonada (2008) la expresión del tiempo discontinuo del instante, explicado por Gaston Bachelard, la expresión de la insubstancialidad del yo lírico, el origen dependiente de los fenómenos y el mostrar transparente, contemplativo, lo que está sucediendo en ese instante, a través del viaje en la intemperie, a la manera de Matsuo Bashō, como otra forma de asir ser, opuesto al tiempo de la acumulación y la conquista de la morada.

Haiku, from José Juan Tablada, has been transculturalized to the forms of Hispanic lyric, so that one can appreciate, for example, the use of rhymes, of classical rhetoric tropes or an enunciation of the lyrical self in elegiac rallies, celebratory, philosophical, etc. However, the Mexican poet, Jorge Tenorio, has sought to approach haiku, not from the Hispanic rhetoric to which it belongs, avoiding rhymes, metaphors or other tropes related to the tradition initiated by José Juan Tablada, but through the idea from the void of Zen Buddhism, which results in the conformation of the poem book Hondonada (2008), the expression of the discontinuous time of the instant, explained by Gaston Bachelard, the expression of the insubstantiality of the lyrical self, the dependent origin of phenomena and the display transparent, contemplative, what is happening at that moment, through the trip in the open, in the manner of Matsuo Basho, as another way of asserting itself, as opposed to the time of accumulation and conquest of the abode.

Offshore wind energy climate projection using UPSCALE climate data under the RCP8.5 emission scenario

MARKUS SEBASTIAN GROSS (2016, [Artículo])

In previous work, the authors demonstrated how data from climate simulations can be utilized to estimate regional wind power densities. In particular, it was shown that the quality of wind power densities, estimated from the UPSCALE global dataset in offshore regions of Mexico, compared well with regional high resolution studies. Additionally, a link between surface temperature and moist air density in the estimates was presented. UPSCALE is an acronym for UK on PRACE (the Partnership for Advanced Computing in Europe)-weather-resolving Simulations of Climate for globAL Environmental risk. The UPSCALE experiment was performed in 2012 by NCAS (National Centre for Atmospheric Science)- Climate, at the University of Reading and the UK Met Office Hadley Centre. The study included a 25.6-year, five-member ensemble simulation of the HadGEM3 global atmosphere, at 25km resolution for present climate conditions. The initial conditions for the ensemble runs were taken from consecutive days of a test configuration. In the present paper, the emphasis is placed on the single climate run for a potential future climate scenario in the UPSCALE experiment dataset, using the Representation Concentrations Pathways (RCP) 8.5 climate change scenario. Firstly, some tests were performed to ensure that the results using only one instantiation of the current climate dataset are as robust as possible within the constraints of the available data. In order to achieve this, an artificial time series over a longer sampling period was created. Then, it was shown that these longer time series provided almost the same results than the short ones, thus leading to the argument that the short time series is sufficient to capture the climate. Finally, with the confidence that one instantiation is sufficient, the future climate dataset was analysed to provide, for the first time, a projection of future changes in wind power resources using the UPSCALE dataset. It is hoped that this, in turn, will provide some guidance for wind power developers and policy makers to prepare and adapt for climate change impacts on wind energy production. Although offshore locations around Mexico were used as a case study, the dataset is global and hence the methodology presented can be readily applied at any desired location. © Copyright 2016 Gross, Magar.

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.

LGBT+ media on the Internet: experiences of communication and information in Mexico

RAUL ANTHONY OLMEDO NERI (2023, [Artículo, Artículo])

Two digital LGBT+ media in Mexico are analyzed to understand the implications of their operation and their articulation with the informational and social needs of sex-gender populations. It starts from the communicational perspective to conceptualize these projects as exercises in technological appropriation but highlighting their empirical intersections with other analytical frameworks. Through the method of systematizing the experience, the trajectories of ANODIS and Seis Franjas Mx have been recovered; through semi-structured interviews conducted with their co-founders in February 2022, the reasons, horizons and challenges that these projects have faced are analyzed. The results show that the lack of LGBT+ content and representations in the media motivate the creation of these projects, which articulate a sense of collaboration and sociality with other users belonging to sex-gender communities. In addition, the people participating in these projects are part of the LGBT+ populations, becoming them producers and consumers of information that claim the gender-identity dimension in the content. Likewise, these initiatives are specified in the youth stage of their co-founders, which refers to rethinking the role of LGBT+ youth in the new forms of activism and socialization mediated by Internet. Finally, given the progressive formation of this area of ​​knowledge and the lack of consensus on its definition, it is proposed to name this interdisciplinary field of study as LGBT+ Communicational Studies, to show an epistemological perspective from communication and a Latin American ontological position.

Remedies for the Inconsistences in the Times of Execution of the Unsorted Database Search Algorithm within the Wave Approach

Manuel Ávila Aoki José Benito Elizalde Salas (2017, [Artículo])

The typical semiclassical wave version of the unsorted database search algorithm based on a system of coupled simple harmonic oscillators does not consider an important ingredient of Grovers original algorithm as it is quantum entanglement. The role of entanglement in the wave version of the unsorted database search algorithm is explored and contradictions with the time of execution of Grovers algorithm are found. We remedy the contradictions by employing two arguments, one of them qualitative and the other quantitative. For the qualitative argument we employ the probabilistic nature of a legitimate quantum algorithm and remedy the above inconsistence. Within the quantitative argument we identify a parameter in the wave version of the unsorted database search algorithm which is related to entanglement. The contradiction with the time of execution of Grovers algorithm is solved by choosing an appropriate values of such a parameter which incorporates entanglement to the wave version of the unsorted database search algorithm. The utility of the present arguments are evident if the wave version of the unsorted data base search algorithm is experimentally implemented through a system of N quantum dots with a harmonic oscillator potential as a confinement potential for each of the quantum dots. Each of the above N vibrating quantum dots must be coupled to an extra single vibrating quantum dot which entangles to all of them. In order to obtain optimal results, the coupling constants of the mentioned quantum dots should be adjusted in the way described in the present work.

Análisis de velocidad de soldadura robotizada para proceso MIG en acero1045 AISI

Carlos Eduardo Hernández Acero (2022, [Tesis de maestría])

Esta investigación denominada “análisis de velocidad de soldadura robotizada para proceso MIG en acero 1045 AISI” busca el desarrollo de un modelo matemático que permita, mediante parámetros conocidos, el cálculo de la penetración de soldadura en piezas unidas con proceso Metal Inert Gas (MIG). El objetivo se centra en buscar la combinación de valores paramétricos para la velocidad de soldadura, el voltaje y la corriente, los que se obtienen mediante la aplicación de un diseño experimental, que, ejecutadas en el proceso, pueda lograr una penetración de soldadura aceptable para la unión de la pieza. El modelo de superficie de respuesta aplicado fue un diseño de experimentos 2k con diseño central compuesto, y posteriormente el modelo se utilizó para estimar la velocidad de soldadura. Este diseño de experimentos se ejecutó por medio del programa estadístico Minitab versión 17. (Hernández Acero et al., 2022). Una vez teniendo la penetración de soldadura deseada en la pieza, se puede calcular la velocidad de soldadura necesaria para el cálculo de tiempo ciclo y utilizar los parámetros definidos de corriente y voltaje. Los valores de estos factores serán útiles para comenzar la programación del robot ya con la celda funcional y reducir el tiempo de arranque en automático (Hernández Acero et al., 2022).

This research, named “robotic welding speed analysis for MIG process in 1045 AISI steel”, seeks to develop a mathematical model that allow, through know parameters, the calculation of welding penetration in parts joined with Metal Inert Gas (MIG) process. The objective is focused on finding the combination of parametric values for robot welding speed, voltage and current, which are obtained through the application of a design of experiments, which, executed in the process, can achieve an acceptable welding penetration for the union of the part. The response surface model applied was a 2k design of experiments with central composite design, and subsequently the model was used to estimate the welding speed. This design of experiments was obtained using the statistical software Minitab version 17. (Hernández Acero et al., 2022). Once having the desired welding penetration in the part, it can calculate the welding speed necessary for the cycle time calculation and use the defined parameters of current and voltage to start programming the robot with the functional cell and reduce the time of startup (Hernández Acero et al., 2022).

Implementación de la metodología Lean Sigma en un proceso de ensamble de engranes y cadenas: Caso de estudio

Omar Celis Juan Alfonso Toscano Moctezuma (2022, [Artículo, Artículo])

RESUMEN

La metodología orientada a solución de problemas propuesta en este artículo de investigación tiene como objetivo actuar a la velocidad de Lean brindando resultados en al menos cuatro semanas. Las cinco fases de esta metodología son: identificar y medir el problema; encontrar las posibles causas que están generándolo; desarrollar una solución empleando herramientas de Lean o de Seis Sigma; una vez implementada la solución, verificarla con una corrida de comprobación y, finalmente, desarrollar un plan de control para asegurar que el estado alcanzado se mantenga en el mediano y largo plazos. Para comprobar la efectividad de la metodología Lean Sigma, se presenta un caso de aplicación en un proceso que no cumple con los requerimientos de entrega a tiempo. Por medio de herramientas Lean, como rebalanceo de la línea, takt time y just in time, se logró incrementar el porcentaje de entregas a tiempo de un 66 % a un 100 % y, a su vez, la productividad aumentó de 1.8 a 2.5 piezas/min*hombre y el lead time disminuyó de 26.07 a 17 segundos, equivalente a una mejora del 35 %. El problema fue resuelto en 24 días y la capacidad del proceso fue de un 2.6 a 3.4 sigma.
