A mean curvature regularized based model for demodulating phase maps from fringe patterns

CARLOS FRANCISCO BRITO LOEZA RICARDO LEGARDA SAENZ ARTURO ESPINOSA ROMERO ANABEL MARTIN GONZALEZ (2018)

We introduce a variational method for demodulating phase maps from fringe patterns. This new method is based on the mean curvature of the level sets of the phase surface that is used for regularization. The performance of the method is illustrated with both synthetic and real data.

Los anuncios publicitarios depositarios de la normalización social

The advertising announce-ments deposit takers of the social normalization

Georgina Sánchez Medrano (2013)

Tema del mes

Este artículo desea destacar que los anuncios publicitarios no son soportes gráficos que conspiran y dan órdenes a los receptores, sino que, más bien, son producto de la cultura que los realiza y, por lo tanto, son “contenedores” de usos y costumbres que ya se encuentran en ella y que, además, coadyuva a mantener. La participación de los anuncios publicitarios en la normalización social es un proceso que involucra aspectos que se relacionan entre sí y dependen uno del otro. En este artículo se hace una propuesta teórica sobre la normalización social mediante los anuncios publicitarios, partiendo de la teoría de los actos del habla, de J. L. Austin y propone la enunciación y la discursivización como procesos conectores entre éstos.

This article wishes to highlight that advertisements are not media which give orders to the recipients, and that they do not comply immediately. But that advertisements are a product of the culture that makes, and therefore are "containers" of habits and customs that are already in it and help to maintain. The share of advertising in social normalization is a process that involves aspects that relate to each other and depend on each other. In this paper a theoretical proposal on the social normalization by commercials, starting from the theory of speech acts, by J. L. Austin and proposes discursivisation enunciation and connectors between them as processes.

The exact solution of generalized Dicke models via Susskind–Glogower operators

BLAS MANUEL RODRIGUEZ LARA Héctor Manuel Moya Cessa (2013)

We show a right unitary transformation approach based on Susskind– Glogower operators that diagonalizes a generalized Dicke Hamiltonian in the field basis and delivers a tridiagonal Hamiltonian in the Dicke basis. This tridiagonal Hamiltonian is diagonalized by a set of orthogonal polynomials satisfying a three-term recurrence relation. Our result is used to deliver a closed form, analytic time evolution for the case of a Jaynes–Cummings–Kerr model and to study the time evolution of the population inversion, reduced field entropy, and Husimi’s Q-function of the field for ensembles of interacting two-level systems under a Dicke–Kerr model.

Evaluación externa de diseño, planeación, operación y resultados de los organismos estatales evaluadores de políticas públicas de Ciudad de México, Jalisco, Hidalgo y Guerrero, 2016-2018.

SANDRA PAOLA JIMENEZ GALLARDO (2020)

La evaluación de las políticas públicas es una estrategia central para dotar de coherencia, eficacia y legitimación a las acciones emprendidas por los gobiernos democráticos al tratar problemáticas de índole pública. A nivel federal México institucionalizó la evaluación de políticas públicas en el año 2004 al prever la creación del CONEVAL (Consejo Nacional de Evaluación de la Política de Desarrollo Social) dentro de la Ley General de Desarrollo Social.

Construction of Social Sustainability in Milk Production Systems in Central Mexico

MONICA ELIZAMA RUIZ TORRES Ana Lorga da Silva CARLOS MANUEL ARRIAGA JORDAN FRANCISCO ERNESTO MARTINEZ CASTAÑEDA (2021)

Objective: To build mathematical models to evaluate the social sustainability of small-scale milk production systems. Design/Methodology/Approach: Thirty small-scale cowsheds were analyzed. Two models were built using multivariate regression, estimated with ordinary least squares and considering the factors that producers perceive as important for social sustainability. Results: The first model (ER) included tangible variables and the second intangible variables (SR). Both models explained more than 80% of the variables associated with social sustainability. Study Limitations/Implications: The results represent an effort to link the statistical analysis with qualitative data that is difficult to quantify. Conclusions: The ER and SR models represent a proposal for counting immaterial indicators so they can be incorporated into the sustainability analysis. Both models could be a methodological proposal to connect statistical data with purely qualitative data such as perception
