Twisted K-Theory for the Orbifold [*/G]

We study the relationship between the twisted Orbifold K-theories {^{\alpha}}K_{orb}(\textsl{X}) and {^{\alpha'}}K_{orb}(\textsl{Y}) for two different twists $\alpha\in Z^3(G;S^1)$ and $\alpha'\in Z^3(G';S^1)$ of the Orbifolds \textsl{X}=[*/G] and \textsl{Y}=[*/G'] respectively, for $G$ and $G'$ finite groups. We prove that under suitable hypothesis over the twisting $\alpha'$ and the group $G'$ we obtain an isomorphism between these twisted K-theories.Comment: version accepted in Pacific Journal of Mathematic

Implementación de un sistema para medir y controlar el abastecimiento del agua para el acueducto comunitario del Barrio Pablo Neruda del Municipio de Sibate Cundinamarca.

Implementar un sistema de automatización industrial con medición y control del tanque de agua del acueducto comunitario del barrio Pablo Neruda.El presente trabajo de grado se diseña e implanta un sistema para medir y controlar el abastecimiento de un tanque de reserva el cual será llenado con el rebose del tanque principal cuando el sistema de control detecte un nivel superior a 240.000 Litros aprovechando el resto de agua evitando la escases y la problemática de racionamientos que atraviesa los habitantes del barrio Pablo Neruda, llenado el tanque de 400 litros de reserva para temporadas de verano o cuando esta se necesite para situaciones especiales sin afectar el suministro de agua. En el acueducto comunitario barrio Pablo Neruda ubicado en el municipio de Sibate (Cundinamarca) cuenta con bajos recursos por lo cual se diseña una implementación utilizando componentes económicos y de bajo consumo de energía. La implementación ayuda a llevar una base estadística del nivel de agua en tiempo real, como de la temperatura que nos servirá para estudio y análisis en futuras investigaciones, ya sea para el medio ambiente de manera cronológica se podrá determinar los tiempos de abundancia y escases del agua como los cambios climáticos que afectan la región. El aprovechamiento de este sistema va a beneficiar a los habitantes de esta región haciendo una mejor distribución del agua y haciendo uso de nuevas tecnologías podríamos mejorar el sistema a futuro colocando paneles solares y resistencias que calienten el agua y le den mejor confort a los habitantes de la región ya que la temperatura llega a 10ºcelsius y la temperatura de confort son de 24ºcelsius.This degree work is designed to implement a system to measure and control the supply of a reserve tank which will be filled with the overflow from the main tank when the control system detects a level higher than 240,000 liters, taking advantage of the rest of the water. Avoiding the shortages and the problem of rationing that the inhabitants of the Pablo Neruda neighborhood face, filling the 400-liter reserve tank for summer seasons or when it is needed for special situations without affecting the water supply. In the Pablo Neruda neighborhood community aqueduct located in the municipality of Sibate (Cundinamarca), it has low resources, so an implementation is designed using low-price components and low energy consumption. The implementation helps to keep a statistical base of the water level in real time, as well as the temperature that will serve us for study and analysis in future investigations, either for the environment in a chronological way it will be possible to determine the times of abundance and scarcity of the water as the climatic changes that affect the region. The use of this system will benefit the inhabitants of this region by making a better distribution of water and making use of new technologies, we could improve the system in the future by placing solar panels and heating elements that heat the water and give better comfort to the inhabitants of the region since the temperature reaches 10º Celsius and the comfort temperature is 24ºcelsius

Evaluation of Colombia economic index for the period 2020 to 2022 with artificial neural networks

This article analyze some of the important macroeconomic indicators in Colombia,such as the Consumer Price Index (CPI), the Gross Domestic Product (GDP), the Representative Market Rate (TRM), the Oil Price (BRENT and WIT) and COLCAP. The objective is to study Colombia's economic.The analysis were obtained with artificial neural networks on Colombian indicators data for the period 2001 to 2018 of the National Administrative Department of Statistics (DANE) and Bloomberg. Concluding, for Colombia, the last two cases are highly favorable for the economy, because they will generate a greater influx of dollars, allowing positive effects on the domestic product and the consumer price index.Este artículo analiza algunos de los indicadores macroeconómicos importantes en Colombia, como el Índice de Precios al Consumidor (IPC), el Producto Interno Bruto (PIB), la Tasa de Mercado Representativa (TRM), el Precio del Petróleo (BRENT y WIT) y COLCAP. El objetivo es estudiar la economía de Colombia. El análisis se obtuvo con redes neuronales artificiales sobre los datos de los indicadores colombianos para el período 2001 a 2018 del Departamento Administrativo Nacional de Estadística (DANE) y Bloomberg. Se concluye que para Colombia, los dos últimos casos son altamente favorables para la economía, pues generarían mayor cantidad de dólares, permitiendo efectos positivos sobre el producto interno y el índice de precios al consumidor

Parallel processing applied to image mosaic generation

The automatic construction of large mosaics obtained from high resolution digital images is an area of great importance, with applications in different areas. In agriculture, the requirements of cartographic accuracy of mosaics of annual or perennial crops are not so high, but the speed in obtaining them is the most critical factor. The efficiency in decision making is related to the obtaining faster and more accurate information, especially in the control of pests, diseases or fire control. This project proposes a methodology based on SIFT Transform and parallel processing to build mosaics automatically, using high resolution agricultural aerial images. Build mosaics with high resolution images requires high computational effort for processing them. To treat the problem of computational effort, the standard OpenMP of parallel processing was used to accelerate the process and results are presented for a computer with 2, 4 and 8 threads

Prevalence of the Metabolic Syndrome Among U.S. Workers

This is the final version of the article. Available from American Diabetes Association via the DOI in this record.OBJECTIVE: Differences in the prevalence of cardiovascular disease (CVD) and its risk factors among occupational groups have been found in several studies. Certain types of workers (such as shift workers) may have a greater risk for metabolic syndrome, a precursor of CVD. The objective of this study was to assess the differences in prevalence and risk of metabolic syndrome among occupational groups using nationally representative data of U.S. workers. RESEARCH DESIGN AND METHODS: Data from 8,457 employed participants (representing 131 million U.S. adults) of the 1999-2004 National Health and Nutrition Examination Survey were used. Unadjusted and age-adjusted prevalence and simple and multiple logistic regression analyses were conducted, adjusting for several potential confounders (BMI, alcohol drinking, smoking, physical activity, and sociodemographic characteristics) and survey design. RESULTS: Of the workers, 20% met the criteria for the metabolic syndrome, with "miscellaneous food preparation and food service workers" and "farm operators, managers, and supervisors" having the greatest age-adjusted prevalence (29.6-31.1%) and "writers, artists, entertainers, and athletes," and "engineers, architects, scientists" the lowest (8.5-9.2%). In logistic regression analyses "transportation/material moving" workers had significantly greater odds of meeting the criteria for metabolic syndrome relative to "executive, administrative, managerial" professionals (odds ratio 1.70 [95% CI 1.49-2.52]). CONCLUSIONS: There is variability in the prevalence of metabolic syndrome by occupational status, with "transportation/material moving" workers at greatest risk for metabolic syndrome. Workplace health promotion programs addressing risk factors for metabolic syndrome that target workers in occupations with the greatest odds may be an efficient way to reach at-risk populations.This research was supported in part by the National Institute on Occupational Safety and Health (grant R01-0H-03915)
