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...

En esta tesis construiremos un algoritmo de descomposición asociado a un problema de optimización convexa separable con restricciones lineales, en particular lo aplicaremos a problemas de programación lineal. Este algoritmo aprovecha la estructura separable de la función objetivo del problema original considerando en cada iteración subproblemas de optimización para cada componente de la función objetivo, siendo estas de menor tamaño que el problema original e independientes entre sí, lo cual permite resolverlos de forma paralela, disminuyendo el costo computacional.

El presente trabajo de investigación tiene como ámbito de estudio el régimen público de pensiones de la ley 19990 a partir de su creación en 1973, pero analizado fundamentalmente, a partir de los años noventa cuando paralelamente se creó el sistema privado de pensiones. Esta investigación tiene como objetivo principal y específicos: • Conocer las causas y consecuencias de la sostenibilidad del régimen de pensiones de la ley 19990. • Detectar la tendencia del estancamiento de la pensión que perciben los jubilados de este régimen de jubilación. • Determinar si el monto percibido es adecuado en contraprestación a las aportaciones efectuadas. Lo que se pretende con este trabajo de investigación es contribuir a explicar y analizar críticamente porque el Sistema Nacional coexiste con el Sistema Nacional Privado de Pensiones en un periodo de liberación de la economía nac...

In the beginning of a new millennium , the countless everyday technological advances result in new ethical questions , some difficult approach and unknown current solution. As there is a permanent reality and questioning the ethical principles , the dilemma comes in thinking that ethics moves on a different plane of self- care activities of daily when really the development of medicine (with its technical progress ) and ethical standards run parallel in the same direction . These seemingly abstract but permanently effective , ethical standards can solve different problems, but many of them are absolutely new for novelty (1). Takes account of situations or dilemmas of increasing complexity, which must be recognized by a thorough search, not to underestimate the desire of patients overestimate the magnitude of their decisions or excess revalue the opinion of specialists or experts.

Peruvian health system, with nearly 70 years of institutionality, unable so far to solve the pressing health problems of the country and excludes a quarter of the population of the possibility of access to health services. Furthermore, it allows a fragmentation of the health system in four subsectors: the Ministry of Health, the Ministry of Labour with EsSalud, the Ministry of Defence with the healing of the army, navy and air force and the Ministry of Interior police health . This fragmentation causes duplication of investments, policy conflicts, parallel rectories and inefficient spending in a country where public spending on health is well below the average for the region. What is needed is a major health reform to end the existing institutional fragmentation and, through a universal insurance, allow access of all people to a health system oriented especially disease prevention and re...

La gestión de proyectos tecnológicos representa un reto para las organizaciones aun cuando existen sinnúmero de metodologías y herramientas que facilitan la gestión de proyectos. El problema se agrava, cuando las organizaciones tienen que ejecutarlos en paralelo. Ante estas dificultades, las organizaciones giran su interés en las oficinas de gestión de proyectos o PMO (Project Management Office). Sin embargo, las organizaciones tienen muchas dificultades cuando tratan de definir el tipo de PMO a implementar y las funciones que deben tener. Por esta razón se propone el presente proyecto de investigación cuyo objetivo es definir un marco de trabajo que permita implementar una PMO y que logre la ejecución eficaz y eficiente de proyectos. Para ello se ha realizado una revisión exhaustiva de trabajos publicados que presentan la implementación y uso de PMO. Tomando en consideració...

El Diseño de un Circuito Electrónico para el Control del Alumbrado de las Cabinas Telefónicas de la Empresa L y G S.R.L, se desarrolló para solucionar los problemas encontrados en el encendido y apagado de las luces de cabinas telefónicas manualmente, ya que, desatiende clientes al trasladarse de su butaca a cada cabina esto genera excesivo gastos de luz para la Empresa en el gasto de luz, que se da a la hora que el cliente termina su llamada ya sea Local, Nacional o Internacional Ya que al integrar tecnología Arduino con la Computadora el control se da más rápido y automatizado, ahorrando KWH (Kilo Watts Hora) sin necesidad de desatender las ventas y servicios prestados a los clientes. Desarrollando para ello dos (2) módulos de gestión, para la administración y control del sistema como son: módulo de Control del alumbrado de cabinas, módulo de consultas de KWH consumidos po...

The Compañía minera Gold Marsa S.A. has been performing its operations in the fields of the mining unit of Parcoy vein Valeria level 3125 with a section of 1.20 x 0.80 m. Which is being executed by the specialized contractor Minera Alfa SA., in the exploitation of Tajos. The characteristics of the site are irregular, finding unstable areas, qualifying as rock MF/P (very fractured ground poor), generating on breakage and damage to the crown, as well as increasing the percentage of the dilution. The exploitation is carried out in conventional form, having verified an excess of consumption of explosives which is reflected in the indicator known as load factor. Other deficiencies in blasting refer to an inadequate explosive column of the drill that instead of 66% were charged to more than 75%, originating on excavations and increased cost of drilling and blasting. In perforation, deviation...

Compania Minera Poderosa SA He has been conducting operations in the ore deposits in the RA2120 section of 4.5 x 4.5 m in Nv. 2120 San Francisco Lode mine Pataz. Reservoir characteristics are irregular, being unstable areas, qualifying as rock MF / P (much fractured poor soil), generating sobrerotura and damage to the crown, and increase the percentage of dilution. The operation is carried out in a conventional manner and are checked overconsumption of explosives, which is reflected in the so-called load factor indicator. Other deficiencies relate to blasting explosive improper drill column instead of 66 % were carried more than 75 %, resulting on excavations and increased the cost of drilling and blasting. In drilling deviations in parallelism they are detected by the absence of guiding , taking the burden no uniform remains and becomes larger at the bottom of the bore , affecting the f...
