Un método para proteger y limitar la infiltración de agua por precipitaciones hacia un depósito de residuos sólidos urbanos (RSU) consiste en la construcción de sistemas de coberturas, las cuales pueden conformarse por diversos materiales y configuraciones. La selección de estos materiales (suelos) se realizan bajo el estudio de sus propiedades hidráulicas y físicas, puesto que, estas nos permitirán definir el orden del material dentro de la estructura de cubierta, y así emplearlos como barrera contra la infiltración, capa de drenaje, soporte, etc. Cabe resaltar que, en ocasiones, las cubiertas de tierra son más económicas que las construidas con materiales sintéticos (geotextiles, geocompuestos y geomembranas). En ese sentido, esta tesis tiene como propósito dotar de alternativas de cubiertas de RSU utilizando únicamente suelos naturales, para ello, en primer lugar, llev...

Self-control is a relevant concept for understanding human behavior across different areas of life. It is associated with positive aspects in various domains and has a pragmatic value as a prerequisite for the successful achievement of long-term goals. In this regard, there are different theories and approaches to the study of self-control. Gaining a deeper understanding of the psychological mechanisms involved in this capacity could guide the design of more effective strategies to foster its development across different contexts. This narrative review article focuses on an updated overview of two of the main theoretical models of this construct, identifying potential similarities and differences. First, Roy F. Baumeister’s model proposes that self-control is a limited resource similar to a muscle. Self-control fatigue is known as “ego depletion”. Second, Kentaro Fujita’s model s...

Esta disertación consta de tres artículos que proponen extensiones de mezclas finitas en modelos de regresión. Aquí consideramos una clase flexible de distribuciones univariadas y multivariadas, que permiten el modelado adecuado de datos asimétricos que tienen multimodalidad, colas pesadas y observaciones periféricas. Esta clase tiene casos especiales tales como distribuciones contaminadas skew-normal, skew-t, skew-slash y skew normal, así como casos simétricos. Inicialmente, se propone un modelo basado en la suposición de que los errores siguen una mezcla finita de mezcla de escala de distribución asimétrica normal (FM-SMSN) en lugar de la distribución normal convencional. A continuación, tenemos un modelo de regresión censurado donde consideramos que el error sigue una mezcla finita de mezcla de escala de distribución normal (SMN). A continuación, proponemos un modelo d...

The purpose of this work is to show that it is possible to model the different resources that the earth offers us (georeourses) by means of the computer tools that engineering currently has at its disposal, with the purpose of contributing to the primary extractive industry in a sustainable way. Datamine is an earth science-oriented engineering software that until now has been used in the mining sector in the modeling of metallic and non-metallic type mineral deposits. This article shows that the same tools used for the modeling of mineralized bodies can be used in surface and / or underground waters in their lagoon and aquifer aspects, respectively. This work proposes the application of the use of drilling rigs, but this time carried out for bodies of water on the surface and / or underground, with the same techniques of witnessing and logging; but with the difference of the techniques ...

Each country's metalworking industry has much economic development, providing companies with jobs and new products. However, companies have different problems in improving various aspects such as production, quality, and delivery times, among others. Therefore, to solve these problems, this article proposes a model based on implementing the Lean philosophy using different tools such as 5S, TPM, SLP, and SMED to increase the overall equipment efficiency (OEE). In addition, work was done on the mindset of workers to sensitize them through the ADKAR Model. A pilot test was carried out to validate the improvements, which gave us good results in the qualification of the audits carried out. In addition, a simulation was carried out in which the Arena software was implemented, and the result was an improvement in the OEE index of 17.60%, a reduction of 44.59 meters in operator movements, and an...

The purpose of this work is to explore the ideals of body and behavior among adult women of our new Peruvian middle class attending a gym. It suggests that the ideals of bodies developed in this place are in closely related to traditional notions of gender roles of our society. But, at the same time, emphasizes the fact that they, not only try to have a body in accordance to social expectation, but also to interact or make friends, and to experience a variety of emotions in performing aerobic activity itself. Finally, the paper explores the meaning that these women give to their experience at the gym. Not only does this experience get them closer to the ideal body, fixed by the social standards of femininity, but the experience turns into an opportunity to discuss and remake those models of femininity, and assert their own discourses of identity.

El modelamiento de datos de áreas en un contexto multivariado es fundamental para evaluar con precisión la relación entre las variables respuesta, así como su dependencia espacial. Asimismo, una estimación precisa de la autocorrelación espacial es útil para identificar patrones espaciales y mejorar el modelado estadístico en campos como la epidemiología, la ecología y la planificación urbana. Sin embargo, los modelos convencionales para la estimación de datos de áreas multivariados, generalmente extensiones del modelo autorregresivo condicional (CAR), tienden a sobreestimar el parámetro asociado a la autocorrelación espacial. En este contexto, esta tesis propone un modelo para datos de áreas multivariados con el objetivo de mejorar la estimación de la autocorrelación espacial en un entorno de múltiples variables respuesta. Este modelo es una extensión del modelo autor...

En el campo de la informática, una ontología es una descripción formal explícita de conceptos en un dominio específico de conocimiento. El uso de esta representación ha permitido compartir un entendimiento común de cómo se debería estructurar información entre personas, instituciones y agentes trabajando en un campo específico. El proceso de creación de estas ontologías puede presentar grandes dificultades. Afortunadamente, las tecnologías más recientes, como los grandes modelos de lenguaje (LLM) pueden ser una gran herramienta para enfrentar estos desafíos. Sin embargo, una de las críticas de mayor peso que recibe esta tecnología es justamente su falta de conocimiento, una insuficiencia que genera las alucinaciones en las que incurre dando por cierta información falsa o incorrecta. Este trabajo presenta dos propuestas. La primera, se propone el uso de los LLM como asi...

A crucial aspect of evaluating and maintaining a photovoltaic (PV) installation connected to the grid is the availability of models that describe its operation reliably in real operating conditions. The nominal power of the PV generator (P*M) is considered an essential input parameter, and several models have been proposed to estimate P*M for characterizing the PV system. In the case of PV generators in outdoor conditions, the American Society for Testing and Materials, the International Electrotechnical Commission, and others have proposed procedures to determine the P*M of the generator. As part of these procedures, monitoring days with ideal conditions is mandatory, notably days with a clear sky, high irradiance values, and low wind speeds. Such restrictions can limit the number of suitable monitoring days, especially in places where clouds frequently form. This thesis proposes a new ...

Most people have claimed that religious beliefs are constituted in the same way as factual beliefs. Eric Mandelbaum suggests a more radical view, for he claims that forming a belief, whether it is religious credence or genuine belief, is similar to having direct contact with a fact that is perceived or represented in our minds: the fixation of beliefs is an effortless and automatic process. This model of our mind’s architecture is called “the Spinozan model”. Neil Van Leeuwen, on the contrary, claims that factual beliefs characterize the background and default frame that we use for tracking truths and behaving in determined ways, whereas religious beliefs function differently. This paper aims to show that, even though Van Leeuwen’s distinction between factual beliefs and religious credences is more plausible than the Spinozan model’s presupposition that both attitudes are the s...

This work is motivated by the physical processes which take place in active galactic nuclei (AGN). They are powerful sources of radiation in a wide wavelength. To gain knowledge about these processes, multiwavelength spectral energy distributions (SED) are used. The current work uses three types of distributions applied to two blazars, a variety of AGN objects. The SED of blazars typically has a double-hump structure which can be explained in terms of two models: the hadronic and the leptonic model. A model built only by leptonic processes (in this case, inverse Compton and synchrotron) has proved to be fairly-good to explain the gamma-ray emission from most blazars. The Python package Naima restricts model parameters to find the best fit for the observed data and characterize the source by proposing processes that could take place there. The SEDs of the Mrk 421 and PKS 0537-441 blazars ...

Purpose: This study aims to propose and test a model of educational quality in marketing-management by incorporating resource-capability variables that are linked to learning outcomes for students and the competitive positioning of universities. Design/methodology/approach – Drawing on the resource-dependence theory this study develops a comprehensive model for measuring educational quality. A sample comprising Spanish university teachers has been used to test the hypothesised relationships by using a two-stage least squares regression analysis while controlling for the possible effect of the public/private nature of the university. Findings – The results validate the model and show that educational capabilities are reliable variables for predicting the educational quality of marketing-management programmes at Spanish universities. Research limitations/implications – Similar to all...

The purpose of the study is to propose a sustainable tourism model for Buenaventura, Colombia. This city is considered Colombia’s main port in the Pacific, and boasts a wealth of biodiversity and nature reserves. This study seeks to address the development shortfall facing sustainable tourism in Buenaventura, which is related to a lack of facilities and deficient road access to tourist sites. Moreover, public policy does not establish guidelines for the development of tourism. In the absence of human capital with specialized training, learning is carried out empirically. A descriptive-exploratory method was used, which enables triangulation in the processing of primary and secondary information.
