The solution of Laplace's equation within a Classical Electrodynamics course is fundamental for the understanding of boundary problems in Electrostatics. In the present research work the analytical and numerical solution is obtained by the relaxation method, of a problem of infinite parallel plates, of the Laplace equation in Cartesian coordinates in an Euclidean space of two dimensions, specifically using the Python programming language, for its use in the teaching of Physics and its better phenomenological understanding. Likewise, the solutions obtained by both solution techniques are compared and discussed.

The research is based on the problems encountered in the production process of companies in the metalworking sector. The problem arises from the low availability of machines in the production process due to working conditions (39.5%), poor maintenance management (40.3%) and poor-quality control (20.2%) that generate low profitability for business. As a solution, Lean Manufacturing tools are implemented to improve the process and increase profitability. The improvement proposal consists of a series of stages: first, the definition of indicators for the measurement of the variables; then, the design and implementation of a pilot in the production process and, in parallel, a simulation system will be designed to evaluate the long-term results. The document concludes that the implementation of the proposed tools will increase the availability of machines and an OEE to 55%, avoiding defective...

In recent years, the number of applications of model predictive control (MPC) is rapidly increasing due to the better control performance that it provides in comparison to traditional control methods. However, the main limitation of MPC is the computational e ort required for the online solution of an optimization problem. This shortcoming restricts the use of MPC for real-time control of dynamic systems with high sampling rates. This thesis aims to overcome this limitation by implementing high-performance MPC solvers for real-time control of fast systems. Hence, one of the objectives of this work is to take the advantage of the particular mathematical structures that MPC schemes exhibit and use parallel computing to improve the computational e ciency. Firstly, this thesis focuses on implementing e cient parallel solvers for linear MPC (LMPC) problems, which are described by block-struct...

New versions of the metaheuristic Multi-Particle Collision Algorithm (MPCA) are presented. In order to provide more effective candidate solutions for an optimization problem, the concept of opposition and reflection is introduced to improve the capacity to find a solution in the search space. Four different strategies to compute the reflected and opposite points are implemented. The performance of all implementations is evaluated over thirty objective functions with different complexities, using serial and parallel versions of the algorithms.

El objetivo de este trabajo de investigación es dar a conocer que las matrices y los sistemas de ecuaciones lineales es un campo de estudio del Álgebra Lineal, curso que se imparte en la universidad a todos aquellos que estudian educación matemática, ciencias e ingeniería. Lo que originó el estudio de las matrices fue encontrar la solución a un sistema de ecuaciones lineales que, a su vez, dio como consecuencia al planteo en su forma matricial, esto motivó al estudio de las propiedades de las matrices. Mas adelante, Gauss y Jordán, dieron un salto en este estudio proponiendo una técnica de solución para estos sistemas lineales de m ecuaciones lineales con n incógnitas, la que dio lugar a tres tipos de situaciones: (1) que el sistema tenga solución única, (2) que el sistema tenga infinitas soluciones y (3) que el sistema no tenga solución. Por otro lado, de manera paralela,...

Convolutional sparse representations and convolutional dictionary learning are mathematical models that consist in representing a whole signal or image as a sum of convolutions between dictionary filters and coefficient maps. Unlike the patch-based counterparts, these convolutional forms are receiving an increase attention in multiple image processing tasks, since they do not present the usual patchwise drawbacks such as redundancy, multi-evaluations and non-translational invariant. Particularly, the convolutional dictionary learning (CDL) problem is addressed as an alternating minimization between coefficient update and dictionary update stages. A wide number of different algorithms based on FISTA (Fast Iterative Shrinkage-Thresholding Algorithm), ADMM (Alternating Direction Method of Multipliers) and ADMM consensus frameworks have been proposed to efficiently solve the most expensive s...

El caso objeto de estudio desarrolla la controversia entre el Perú y Chile relativa a su límite marítimo lateral sobre el Océano Pacífico. Ambos Estados tenían puntos de vista diametralmente opuestos. Si bien para el Perú no existía un límite marítimo establecido, para Chile éste se hallaba plenamente definido por una serie de instrumentos suscritos por las partes. Luego de buscar, sin éxito, una solución a este desencuentro por la vía diplomática, empleando los medios de solución pacífica de controversias reconocidos internacionalmente, el 16 de enero de 2008 el caso fue elevado por el Perú a la Corte Internacional de Justicia. Durante el proceso, las partes presentaron sus posiciones respecto de la existencia de un límite marítimo entre ellas y del curso que éste debería tener. Tras analizar las argumentaciones y los instrumentos que fueron considerados relevantes...

Recurrent flooding in the mining works, deficiencies in the operation of pumps, unforeseen stoppages, and lack of water availability in the processes, affect the operations in the subway mine. The traditional solution adopted is to wait for maintenance times for its post evacuation, generating stoppages, consumption of water from the wells and inefficiency in the daily water demand. Therefore, this article presents a new approach that will expand the traditional methods by introducing a prediction model using probabilistic methods. This approach will allow the design of an optimal water distribution system, the efficient control in the maintenance and covering of the recirculated water demand inside the mine. Variables describing problems related to pump flow, pressure zoning and the type of pump distribution, either in series or in parallel in the pumping system, will be determined. Als...

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...

La evolución del mercado de la tecnología de la información hacia los servicios en la nube y el crecimiento innegable del tráfico de datos han desencadenado la concepción de los centros de datos a gran escala. Intrínsecamente, los servicios en la nube requieren capacidad para hacer frente al alto tráfico de datos para servir a los clientes y los procesos internos requeridos para servicios de alta calidad. Las tecnologías ópticas han permitido manejar un mayor tráfico de datos y la capacidad de fibra multinúcleo para la transmisión de alta velocidad de datos es una solución prometedora para las interconexiones de centros de datos, permitiendo la transmisión de señales de reloj paralelas a la transmisión de datos, aumentando así el rendimiento al reducir la sobrecarga de sincronización del reloj y el tiempo de recuperación del reloj.
