We study a system formed by M dimers through half-filled two-site Hubbard model, with two electrons. Our approach use the third version of Nonextensive Statistical Mechanics as tool for calculating thermodynamic and magnetic parameters such as entropy, internal energy, magnetization and specific heat. In the computer simulations, we vary the q entropic index values between 1 and 2, such that, q = 1.0, 1.4, 1.7 and 2.0. These values are interesting to study small magnetic systems. We find the critical temperature regions in simulations with the simple Hubbard model, i.e. without the intersite interaction. For other side, adding this additional term, we notice an enlargement and shifting of the thermodynamic parameters comparing with the obtained from simple Hubbard model; even more, we found in some cases the absence of the critical temperature regions.

Presentamos una propuesta didáctica diseñada para apoyar la enseñanza de la física y la astronomía en contextos de aprendizaje que estén caracterizados por problemas complejos y el uso de herramientas computacionales. Nuestra propuesta se fundamenta conceptualmente en elementos seleccionados del conectivismo, el pensamiento sistémico no lineal y el aprendizaje basado en problemas. En lugar de buscar una validación empírica, nosotros presentamos un marco conceptual estructurado que organiza el aprendizaje a través de etapas interconectadas: exploración conceptual, estructuración lógico-matemática, formulación algorítmica, implementación computacional e interpretación física. Hemos utilizado un caso práctico de cinemática estelar: el cálculo de la velocidad relativa al Sol de 20 estrellas cercanas. En consecuencia, nuestros resultados muestran que este marco integra l...

The objective of the research is to present a model of knowledge management for micro and small enterprises engaged in the sale of computers and software; for which we have considered the identification of activities that generate knowledge, the mechanisms that contribute to communication, communication control and integration of knowledge; as well as the identification and understanding of the contextual elements associated with communication, control and generation of knowledge. These elements were analyzed through the study of five cases in qualitative research and thirty respondents in quantitative research. The interview, direct observation, documents and surveys were the main data collection methods used in the study and the empirical validation of the model of knowledge management. The results indicate that the generation of knowledge depends on the technical personnel of enterpri...

In the present paper, a computational model is performed by Cellular Automata (Cell-DEVS) that describes the transmission dynamics of Varicella in a closed group of people where the disease can be spread. From the perspective of mathematical epidemiology we have the mathematical model SEIR of W.O. Kermack and A.G. McKendrick that represent the dynamics of the epidemic, in our case Varicela, where the computational simulations are performed both by the Numerical Methods and the Cellular Automata to analyze the development of the disease.

Zika virus spreads to people primarily through the bite of an infected Aedes aegypti species mosquito. But it Zika can also be passed through sex from an infected to his or her sex partners and it can be spread from a pregnant woman to her fetus. Zika continues to spreading geographically to areas where competent vectors are present. Although a decline in cases of Zika virus infection has been reported in some countries, or in some parts of countries, vigilance needs to remain high. In this work, we propose a mathematical model that uses diffusion-advection equations to study the impact of the Zika epidemic. We present a numerical scheme linking finite elements (FEM) with finite differences to solve the model. The computer simulations are performed for Paramaribo and Santa Ana that have different demographic characteristics and allow us to extend the study to other regions.

This study aims to evaluate the future of confirmed cases of Covid-19 in Peru, using the Gompertz nonlinear regression model. The data were obtained from official reports of the Peru Ministry of Health (MINSA). The accumulated value of fatal cases was subjected to iterative analysis by the non-linear least-squares method to achieve a model. Given the first-order derivative of the predictive model was obtained the daily fatal cases curve. Using the fatality rate as the proportion between infected and fatal cases, both of them would also provide days average lag to estimate the epidemic curve. For the moment, the predictive model suggests that Peru would be in a slow descent in the epidemic curve, moving away from the peak of contagions per day. The trend of reaching about 550 thousand infected and 19 thousand deaths until the end of the year 2020. The predictions of the mathematical model...

Change detection between images is a procedure used in many applications of remote sensing data. Among these applications, the identification of damaged infrastructures in urban areas due to a large-scale disaster is a task that is crucial for distributing relief, quantifying losses, and rescue purposes. A crucial consideration for change detection is that the images must be co-registered precisely to avoid errors resulting from misalignments. An essential consideration is that some large-magnitude earthquakes produce very complex distortions of the ground surface; therefore, a pair of images recorded before and after a particular earthquake cannot be co-registered accurately. In this study, we intend to identify changes between images that are not co-registered. The proposed procedure is based on the use of phase correlation, which shows different patterns in changed and non-changed are...

In view of the evident potential shown by new technologies for education more and more companies are developing and implementing training programs using the facilities provided by these technologies. In turn new providers have emerged that develop training programs based on these new technologies seeking greater efficiency and lower costs compared to traditional training. The objective of this work is to identify the relevant factors for the success of the training programs with technological support starting from the case of a Spanish company analysed in depth. These factors have been articulated in a conceptual model that respects some theoretical proposals made previously and with which fits reasonably well.

En el ámbito de la construcción a nivel internacional, se requiere estandarizar y catalogar los objetos y/o elementos que forman parte del ciclo de vida de proyectos, con la finalidad de facilitar el uso correcto de la información en todos los procesos relacionados a la construcción, como la cuantificación de acuerdo con las especificaciones técnicas, el cálculo de presupuestos, cuantificación de materiales, entre otros. Este tema ha tenido mayor importancia desde que la metodología BIM (Building Information Modeling) ha tenido mayor acogida al desarrollar proyectos de construcción, ya que permite realizar una pre-construcción del proyecto a través de modelación de objetos 3D orientados geométricamente. (Convers Rivera, 2020) La norma ISO 12006 se realizó para la organización de información de obras de construcción y consta de parte 2 - Marco de clasificación y parte 3...

In this work, we present two mathematical models for the Zika diffusion by using (1) ordinary differential equations with exposed state and, (2) ordinary differential equations with delay (discrete), which is the time it takes mosquitoes to develop the virus. We make a comparison between the two modeling variants. Computational simulations is performed for Santa Ana, which is that is prone to develop the epid...

The interactive documentary field has a collaborative dimension since its beginning. This research proposes a model for the analysis of the participation of online communities within interactive documentary, developed on the basis of the previous scientific literature on this topic. Then, analysed case studies have shown the diversity of forms regarding contribution from online communities. On the basis of the different trends observed, five participative designs with different intensities and purposes have been described. Finally, the model has been applied to each design for its evaluation, allowing us to conclude that a significant participation would have to combine several of these designs considering the articulation of participant communities around documentary as well as its contribution to documentary meaning.

Research on the bibliographic review studies on collaborative learning at the university level published in the last five years, allows to verify an absence of systematic comparative analysis of explicit and exhaustive analytical criteria that enables ordering of the different contributions. Precisely, the objective of this work was to establish a referential analytical model that allows a clear systematization of the corpus of articles recovered in the period 2018-2022. To meet this objective, a bibliographic search was carried out in the databases: SciELO, RedALyC, Eric and Dialnet. 71 studies were recovered. In the first part of the manuscript, this corpus of research was analyzed based on the constructed analytical criteria or variables. In the second part, the variables of the proposed model were analyzed inclusively. Based on this systematization, 12 studies were selected that can ...
