Evaluación del método ajuste por objetivo de la máquina cerradora continental en la Fábrica Productiva Yara (Original)

In Yara Productive Factory, which belongs to the Unidad Empresarial de Base Conservas de Vegetales de Granma, there is a ½ kg tinplate container sealing machine that closes different products, both for domestic consumption and for tourism. Among the main objectives established to determine the quality in the manufacturing processes of the products is related to the evaluation and analysis of the parameters of the sealing or double sealing, which must comply with the standards established for this process. Due to the great variety of container formats that exist and their different characteristics, the breakages that occur and the replacement of some of their components, it is necessary to make constant adjustments in the sealing machines that define the quality and acceptability of the closure. These adjustments require great precision, time and the use of some resources in the process, in order to guarantee the tightness of the package and the preservation of the packaged and capped products. The objective of this article is to evaluate the effectiveness of the target adjustment method in the optimal adjustment of the Continental seamer for ½ kg containers, in order to obtain a closure with the recommended specifications according to the standards, using a minimum of time and resources. Theoretical methods (analysis-synthesis, induction-deduction), empirical methods (documentary analysis, experiment) and mathematical statistics for data processing were used for the development of this research.En la Fábrica Productiva Yara, perteneciente a la Unidad Empresarial de Base Conservas de Vegetales de Granma, existe una máquina cerradora de envases de hojalata de ½ kg que realiza la acción del tapado de diferentes productos, tanto para el consumo nacional como para el turismo. Entre los principales objetivos establecidos para determinar la calidad en los procesos de elaboración de los productos se encuentra el relacionado con la evaluación y análisis de los parámetros del cierre o doble cierre, los cuales deben cumplir con las normas establecidas para dicho proceso. Por la gran variedad de formatos de envases que existen y sus diferentes características, por las roturas que se presentan y por el reemplazo de algunos de sus componentes, es necesario realizar constantes ajustes en las máquinas cerradoras que definen la calidad y aceptabilidad del cierre. Estos ajustes requieren de gran precisión, de tiempo y de la utilización de algunos recursos en el proceso, para garantizar la hermeticidad del envase y la conservación de los productos envasados y tapados. En el presente artículo se  propone como objetivo evaluar la efectividad del método ajuste por objetivo en la regulación óptima de la cerradora continental de envases de ½ kg, para la obtención de un cierre con las especificaciones recomendadas según los estándares, haciendo uso de un mínimo de tiempo y recursos. Para el desarrollo de esta investigación se emplearon métodos teóricos (análisis-síntesis, inducción-deducción), métodos empíricos (análisis documental, experimento) y estadísticos matemáticos para el procesamiento de los datos

Definition of a temporal distribution index for high temporal resolution precipitation data over Peninsular Spain and the Balearic Islands: the fractal dimension; and its synoptic implications

Precipitation on the Spanish mainland and in the Balearic archipelago exhibits a high degree of spatial and temporal variability, regardless of the temporal resolution of the data considered. The fractal dimension indicates the property of self-similarity, and in the case of this study, wherein it is applied to the temporal behaviour of rainfall at a fine (10-min) resolution from a total of 48 observatories, it provides insights into its more or less convective nature. The methodology of Jenkinson & Collison which automatically classifies synoptic situations at the surface, as well as an adaptation of this methodology at 500 hPa, was applied in order to gain insights into the synoptic implications of extreme values of the fractal dimension. The highest fractal dimension values in the study area were observed in places with precipitation that has a more random behaviour over time with generally high totals. Four different regions in which the atmospheric mechanisms giving rise to precipitation at the surface differ from the corresponding above-ground mechanisms have been identified in the study area based on the fractal dimension. In the north of the Iberian Peninsula, high fractal dimension values are linked to a lower frequency of anticyclonic situations, whereas the opposite occurs in the central region. In the Mediterranean, higher fractal dimension values are associated with a higher frequency of the anticyclonic type and a lower frequency of the advective type from the east. In the south, lower fractal dimension values indicate higher frequency with respect to the anticyclonic type from the east and lower frequency with respect to the cyclonic type
