The report addresses the management of parallel processes and synchronization in concurrent systems, highlighting common problems in accessing shared resources that affect efficiency and stability. It also highlights the need to optimize the management of large volumes of data and improve academic cooperation to develop advanced solutions.The objective of the study is to identify and analyze synchronization strategies that optimize parallel processes, evaluating their effectiveness in different scenarios and offering recommendations based on recent literature. A systematic review was conducted using the PRISMA methodology, selecting relevant articles published in the last five years and formulating key questions to guide the analysis. The results highlight that non-blocking strategies are more effective for managing shared resources, and techniques such as the use of mutex and actor mode...

Style transfer is a natural language processing generation task, it consists of substituting one given writing style for another one. In this work, we seek to perform informal-to-formal style transfers in the English language by using a style transfer model that takes advantage of the GPT-2. This process is shown in our web interface where the user input a informal message by text or voice. Our target audience are students and professionals in the need to improve the quality of their work by formalizing their texts. A style transfer is considered successful when the original semantic meaning of the message is preserved after the independent style has been replaced with a formal one with a high degree of grammatical correctness. This task is hindered by the scarcity of training and evaluation datasets alongside the lack of metrics. To accomplish this task, we opted to utilize OpenAI’s G...

Metal mining is one of the economic pillars of the Peruvian economy. Peru is the main producer of gold, zinc, lead, and tin in Latin America and the second largest producer of copper, silver, and zinc worldwide. Despite its economic importance, mining has also left a plethora of Mining Environmental Liabilities (MEL) whose inadequate waste management represents a risk for both the environment and human health and is a common trigger of social problems. The Cajamarca región is the second región in Peru in terms of the number of MEL sites with the majority of them located in the Hualgayoc district. The goal of the PhD project is the assessment of the environmental impact of MEL in the Peruvian Andes using as an example two post-mining sites in the Hualgayoc district. This evaluation includes the study of soils and native plant species in terms of their metal accumulation potential and th...

Esta investigación tiene como finalidad mejorar la calidad de los afirmados de los caminos vecinales de la ciudad de Candarave-Tacna, producidos en canteras mediante la “Estabilización de afirmados obtenidos de las canteras Arunta, Cerro Blanco, Hospicio, Miculla y Morán para conformación de Afirmados incrementando los valores referenciales de los parámetros de calidad propuestos por el manual de carreteras EG 2013”. Los estabilizadores seleccionados para el material son la Tierra de Chacra y el estabilizador Z con polímeros. La Tierra de Chacra desempeña un papel crucial al incrementar la proporción de finos en la mezcla de agregados, mientras que el estabilizador Z destaca por sus propiedades que optimizan la cohesión y compactación del material afirmado. Para la estabilización, se seleccionaron muestras de estudio provenientes de canteras con la mejor curva granulométr...

Radioteleskope sind verschiedenartigen Umwelteinflüssen ausgesetzt. Dadurch hervorgerufene Verformungen der Reflektoroberfläche verändern deren geometrischen Eigenschaften und können die ursprüngliche Position und Form des Brennpunkts verändern. Eine Abweichung dieses Brennpunkt von der Lage der Primärantenne beeinflusst die Leistungsfähigkeit des Teleskops. Die vorliegende Arbeit zeigt eine Methode zur theoretischen Abschätzung der Verformung durch das Eigengewicht des Reflektors des INRAS RT–20. Jene nach der Idee des homologen Designs von Hoerners konstruierten Teleskopen weisen eine Stützstruktur auf, die die Reflektorfläche unabhängig vom Elevationswinkel in einer der ursprünglichen Form ähnlichen Gestalt halten. Somit kann die Verformung durch das Nachführen der Primärantenne ausgeglichen werden. Grundlage der Untersuchung ist ein vorhandenes Strukturmodell des RT...

Este proyecto se centra en evaluar la prefactibilidad de una fábrica de ladrillos a base de PET con el propósito de satisfacer la demanda en la región Lambayeque. El estudio ha arrojado resultados positivos desde el punto de vista comercial técnico y económico. Para cumplir con los objetivos trazados primero se tuvo que determinar la viabilidad comercial del proyecto, para lograrlo se realizó un estudio de mercado, en el cual se realizó el análisis del comportamiento de la demanda y oferta, los resultados revelan una demanda proyectada para los próximos 5 años que alcanza hasta 9 millones de soles en ventas, lo que respalda la viabilidad comercial del proyecto. Seguidamente para el segundo objetivo se evaluó la viabilidad de la producción de ladrillos PET y se desarrolló un plan de producción que prevé la fabricación de 9,521 mil ladrillos para el quinto año de operació...

This research is the analysis of administrative processes of the department of customer service in which it developed a business plan, contact and customer relationship, also, with the employees of the Tiendas Metro in the city of Trujillo. In this study, we considered seriously the theme of service, in order to understand and be able to establish parameters for the creation of a Service Model adapted to each organization which is involved in parallel see every administrative processes implemented and implemented within a Customer Service Department of a company product number (case study) and realize that the service itself is meaningless if not accompanied by adequate and well-evaluated business processes created. The above leads us to consider very carefully the processes of recruitment and selection of personnel for the service area, as not all people have the right skills that were ...

To more economic growth, less chronic malnutrition? What factors determine the persistent association between extractive economies and prevalence of chronic malnutrition? The answer to these questions is made taking as the unit of analysis the regions in Peru from 1950 to 2010. It is considered a sample of five regions: Ancash, Cajamarca, Huancavelica extractive mining and agricultural tradition, and Lambayeque to Ica economy based on agribusiness, manufacturing and trade. The study shows, in the period, parallel processes and identify a complex range of social determinants between the continued growth and a tendency to decrease in chronic malnutrition, but with different speeds in the regions over the past decade envisioning opening an epidemiological transition in nutrition. It uses information from the INEI, ENDES, project evaluations, research reports and interviews with mothers of ...

El arroz es el cereal más importante para más del 50% de la población mundial, sin embargo las enfermedades pueden limitar su producción. El añublo bacterial de la panícula, es una de las enfermedades con mayor vigilancia en el cultivo de arroz, debido a los cambios climáticos que exacerban su incidencia. El agente etiológico de la enfermedad, se atribuye a Burkholderia glumae y Burkholderia gladioli. El presente estudio, tuvo como objetivo seleccionar controladores biológicos contra B. glumae THT, a partir de la microbiota endofítica del cultivo de arroz. Para ello, se realizaron colectas de 7 cultivares de arroz en los departamentos de Tumbes, Piura, Amazonas y San Martín. Las muestras de arroz fueron procesadas para aislamiento de grupos funcionales asociados a control biológico (Bacillus, Pseudomonas y Burkholderia). Las cepas de bacterias endofíticas fueron seleccionada...
