The resolution of triangular systems is a computational nucleus widely used in various scientific applications. This research performs the implementation and comparison of several parallel algorithms against an efficient sequential algorithm for solving triangular systems. The algorithms are distinguished by the way of partitioning the matrix and the allocation to the processors. The analysis of the behavior of the algorithms is performed in the solution of systems of linear superior triangular equations in a cluster of computers. For this, the arithmetic time, communication time, speed-up, and maximum efficiency metrics are taken into account. Experiments were performed for each algorithm with different matrix sizes on various processors. The algorithm with the best results was the one that blocks the rows of the matrix and applies a cyclical distribution in the cluster.

Compañías mineras están en búsqueda constante de nuevas tecnologías para aumentar su productividad. Una de las tecnologías que les permite realizar la reconstrucción de la superficie sin poner en riesgo la vida de sus trabajadores es el uso de sensores LiDAR junto con plataformas móviles que les permiten rotar el sensor para realizar un escaneo completo de la estructura. Sin embargo, el procesamiento de los datos se realiza a través de ordenadores situados fuera de la mina, debido a su alto coste computacional, lo que se traduce en un alto coste de tiempo. En esta tesis presento como objetivo principal el diseño de un algoritmo paralelo para la fusión de nubes de puntos capturadas por un LiDAR y la reconstrucción de la superficie en tiempo real, con el fin de reducir el tiempo de procesado, teniendo en cuenta información a priori del patrón de barrido de los puntos. En la l...

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.

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...

Swarm robotics focuses on the study and development of robot systems containing a large number of agents that interact with each other in a collective behaviour in order to achieve tasks or overcome obstacles. Bristlebots are vibration-driven mobile robots. They are characterized by small size, high speed, simple design and low costs for production and application – qualities which are advantageous for agents of swarm robotic systems. However, most studies have been developed over systems with no control or systems with two or more actuators. The aim of this master thesis is the development of a bristle based robot agent for a swarm robotics microsystem with units for locomotion, sensing, data processing, control, communication and energy storage. New approaches in modelling and development of swarm agents are given, and a robot prototype is presented. The robot is driven by a single D...

The Ecuadorian Amazon region is permanently subject to deforestation processes and in parallel to the implementation of agricultural, and livestock management systems that can affect soil quality. This study assessed the effect of different land use types on soil quality using the Integrated Soil Quality Index (SQI) and minimum indicators. To do this, it considers representative soil samples, 4 types of land use, and a productive landscape in the province of Pastaza. The land use types evaluated were sugarcane (SC), agrosilvopastoral System (ASPS) silvopastoral timber system (SSTT), and secondary forest (SF). Land use type had significant effects on some soil properties and, therefore, on soil quality. The soil quality index was developed using BD, Ca+Mg/K, and SOM which had the highest weighting values, suggesting a higher contribution to the final SQI. The Soil...

En los últimos años, la llegada de las cámaras de profundidad de bajo costo y sensores LiDAR ha incentivado a las industrias a invertir en estas tecnologías, lo cual incluye también mayor interés en investigaciones sobre procesamiento digital de señales. En esta ocasión, la reconstrucción tridimensional de túneles mineros utilizando LiDARs y un robot de auto-navegación ha sido propuesta como proyecto de investigación, y el presente trabajo forma parte en cargándose del alineamiento de nubes de puntos tridimensionales en tiempo real, un proceso que es más conocido como Registro de Nubes de Puntos. Existen muchos algoritmos que pueden resolver este problema, pero para el proyecto, el algoritmo solo necesita calcular la alineación fina y rígida. Al comparar los algoritmos de registro más avanzados, se encontró que el popular algoritmo ICP es el más adecuado para este caso...

This paper presents the first published report of a national-level effort to implement the integrated management of childhood illness (IMCI) strategy at scale. IMCI was introduced in Peru in late 1996, the early implementation phase started in 1997, with the expansion phase starting in 1998. Here we report on a retrospective evaluation designed to describe and analyze the process of taking IMCI to scale in Peru, conducted as one of five studies within the multicountry evaluation of IMCI effectiveness, cost and impact (MCE) coordinated by the World Health Organization. Trained surveyors visited each of Peru’s 34 districts, interviewed district health staff and reviewed district records. Findings show that IMCI was not institutionalized in Peru; it was implemented parallel to existing programmes to address acute respiratory infections and diarrhoea, sharing budget lines and management st...

Buscamos establecer un paralelo entre algunos conceptos del psicoanálisis freudiano y el concepto kantiano del «mal radical», el cual fue adoptado por Hannah Arendt para referirse a las atrocidades cometidas por el régimen totalitario nazi contra los judíos en la Shoah. Arendt considera el nazismo como un régimen totalitario basado en una ideología racial que proporcionó la «ficción creíble» que argumenta que gracias a las Leyes de la Naturaleza surgió la raza aria - «superior y pura» - para la cual su objetivo principal fue destruir a su contraparte, el pueblo judío «infrahumano». Los nazis utilizaron campos de concentración y exterminio para eliminar a millones de personas consideradas «superfluas» y «prescindibles». En este artículo analizamos la obsesión de los nazis de exterminar a los «infrahumanos», utilizando, entre otros, el concepto psicoanalítico fr...
