Título : En defensa de Dios
Authors: Miramontes de León, Gerardo
Resumen : ¿Dios necesita quien lo defienda? ¿Es necesario inventar milagros?
En este texto, se propone una metáfora de un dios, no el de las escrituras, en una fórmula que contiene lo infinitamente pequeño y lo infinitamente grande y se retoman algunas ideas de grandes pensadores como Spinoza y Asimov, entre otros. Se propone reflexionar si la descripción que se hace de Dios se puede reconsiderar.
Descripción : Does God need someone who defends him? Is it necessary to invent miracles?
In this text, a metaphor of a god, not the one of the scriptures, is proposed in a formula that contains the infinitely small and the infinitely large and some ideas of great thinkers such as Spinoza and Asimov, among others, are reviewed. It is proposed to reflect on whether the description made of God can be reconsidered.2022-09-10T00:00:00ZMemorias de un profesor para ingenieros

Título : Memorias de un profesor para ingenieros
Authors: Miramontes de León, Gerardo
Resumen : Sin pretender ser protagonista, quizá los años, las circunstancias, o qué sé yo, me han convencido escribir estas memorias para compartir una versión sobre los pasos vacilantes de un profesor común, a veces criticado, y otras no tanto. Esta historia es la historia de muchos otros profesores. Todos aquellos que tuvieron que ausentarse de su familia, con el único fin de continuar su formación académica, lo saben.2021-05-30T00:00:00ZPhysical characterization of sunflower seeds dehydrated by using electromagnetic induction and low-pressure system

Resumen : Drying is a widely used food preservation process in which water removal minimizes much of the moisture that causes deterioration reactions that impact the bioproduct quality. The objects of studying are high oleic sunflower seeds which are recognized as a worldwide source of edible oil; consequently, they have significant importance on health and food security. This work presents part of the results of a systematic study to compare the affectations on the several physical parameters of sunflower seeds and kernels with the Thermo-Solar Dehydration method (TSD) compared to Dehydration with Electromagnetic Induction at Low Pressures (DEMILP), finding that the in the last one the time to reach the 8% of the total moisture content was 2.5 times shorter, interesting physical effects and an increment of 5% in the volumetric expansion coefficient, reflected in a reduction of the cut resistance (Dehull) of 0.5KgF significant advantages for the food drying industry.2020-01-09T00:00:00ZAlternative sampling functions for single-pixel imaging with a digital micromirror device

Resumen : Single-pixel imaging employs structured illumination to record images with very simple light detectors. It can be an alternative to conventional imaging in certain applications such as imaging with radiation in exotic spectral regions, multidimensional imaging, imaging with low light levels, 3D imaging or imaging through scattering media. In most cases, the measurement process is just a basis transformation which depends on the functions used to codify the light patterns. Sampling the object with a different basis of functions allows us to transform the object directly onto a different space. The more common functions used in single-pixel imaging belong to the Hadamard basis or the Fourier basis, although random patterns are also frequently used, particularly in ghost imaging techniques. In this work we compare the performance of different alternative sampling functions for single pixel imaging, all of them codifi ed with a digital micromirror device (DMD). In particular, we analyze the performance of the system with Hadamard, cosine, Fourier and noiselet patterns. Some of these functions are binary, some others real and other complex functions. However, all of them are codifi ed with the same DMD by using different approaches. We perform both numerical and experimental tests with the different sampling functions and we compare the performance in terms of the efficiency and the signal-to-noise ratio (SNR) of the fi nal images2019-03-04T00:00:00Z
