Nowadays, some of the most popular tools for parallel programming are Message Passing Interface and Open Multi-Processing. It is of interest to compare these tools in solving the same kind of problems, because of the use of different approaches to inter-task communication. This work attempts to contribute to this goal by running trials in a centralized shared memory architecture in the case of problems with an entirely parallel solution. The selected case study was the parallel computation of Mandelbrot set. Trials were conducted for different iteration limits, processors amount, and C++ implementation variants. The results show better performance in the case of Open Multi-Processing.

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...

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...

En esta investigación comenzamos problematizando un impase pedagógico en la Universidad Nacional de Música que se encuentra actualmente en un proceso de licenciamiento que reforma su estructura. Esto es, pasar de la denominación de Conservatorio Nacional de Música a Universidad Nacional de Música. Dicha coyuntura supone un momento de revisión crítica de la propuesta pedagógica. Sin embargo, esta se distancia de las necesidades que el mercado laboral actual impone a los músicos profesionales. A través de una selección de momentos particulares a lo largo de la historia de la institución hasta la actualidad, trazaremos una suerte de historia paralela de lo que consideramos el trasfondo estructural e ideológico de dicho impase. Por otro lado, analizaremos las salidas laborales de los egresados de la institución para dar cuenta de la relación que existe entre la propuesta peda...

Low Density Parity Check codes presents itself as the dominant FEC code in terms of performance, having the nearest performance to the Shannon limit and proving its usefulness in the increasing range of applications and standards that already used it. Low power devices are not except of this rapid development, where it emerges the necessity of decoders of low power without totally sacrificing performance or resource usage. The present work details the devolopment of a LDPC decoder compliant with the DVB-S2 standard for digital television, motivated for its already established use in uplink and downlink satellite applications and its great performance at large code lengths. This research presents the study of the min-sum algorithm and the design of the elements that conform the core decoder, including both functional units (variable and check nodes), memory blocks and routing network.

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...

En los últimos años los índices de aceptación y confianza de la población en su PNP ha disminuido del 21% en el 2022, al 19% en el 2023, paralelo a ello se ha evidenciado, tal como lo demuestran estudios realizados, que en los últimos seis años, se ha pasado al retiro por medida disciplinaria a 22,837 suboficiales de los cuales más de la mitad corresponde al grado de suboficial de tercera, por la comisión de delitos como secuestro, extorsión, violencia familiar, venta de armas, corrupción entre otros y, faltas muy graves que fueron sancionados con la expulsión del cuerpo policial. Algunos estudios apuntan a la deficiente formación del elemento policial, otros a una mala selección. Se ha identificado que el problema deriva de la reducción de postulantes cada año, a los procesos de selección de los nuevos integrantes del cuerpo policial, habiéndose detectado que cada año...
