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.

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.

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...

Most of the problems concerning the fluids flow in conduits and tubes they imply the prediction of the conditions in a section of a system, when the conditions of some other section are known. In any section of this system, generally we are worried about the pressure of the fluid, the speed of the flow and the elevation of the section. In a line of pipe in series the loss of total energy is the sum of the great and small individual losses. This affirmation is in agreement with the principle of which the equation of the energy is a way to both take into account all the energy in the system between points. The nature parallel systems requires that the technique used for their analysis is different from which is used in series in the analysis of the systems. In general, a parallel system can have any number of branches. It stops most of the problems of this type, the objective is to determi...

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.

A significant number of projects specifically oriented to the promotion of rural women are currently being developed throughout the country. Parallel to the programs implemented by the public sector (CIPA, Ministry of Labor and Social Promotion), non-governmental organizations have designed localized coverage actions aimed at serving this sector of the population. Various events in recent years have brought together the promoters involved in these actions and through discussions and workshops a common problem has begun to be configured for this type of action. Our intention here is to evoke some of the converging problems detected and outline some guidelines that allow us to fine-tune the approaches of the projects and optimize the impact of the actions.

An assessment of part of a family planning program is presented in a social environment characterized by high fertility, low contraceptive use and knowledge and great interest in information and practice of family planning methods. Accidental pregnancy rates and subsequent expulsions are similar to those found in urban environments and sea level. By contrast, first expulsions rates are higher than those established for suburban and metropolitan populations sea level, so it could be considered an effect of biological, possibly related to altitude conditions. The application of IUDs appears to face a number of problems arising from the socio-cultural status of the population. Although theoretically would be the most useful means of contraception in Cerro de Pasco, its use is affected by the limited knowledge of patients on the characteristics of the method, which makes it sensitive to the ...

The work analyzes the contributions of Mercedes Rodrigo Bellido and Victoria Bossio Herrera, pioneers of psychology in Colombia, highlighting their impact from complementary approaches. Rodrigo, born in Spain, introduced psychotechnics and founded the first university psychology program in the country, consolidating the discipline as autonomous and applied to vocational guidance and child well-being. Bossio, Colombian and the country's first doctor in psychology, focused her work on psychopedagogy, promoting education for children with high abilities and learning difficulties, in addition to addressing problems such as child abandonment. Both faced gender barriers, but overcame the challenges through solid training and an innovative approach, being leaders in the integration of psychology into the educational and social field. His contributions were essential to professionalize the disci...

The mental health of college students has been the source of research, projects, and public policies involving education, health, and psychology professionals. Having as its axis the study of mental health and the phenomenon of psychological illness, this systematic review aims to characterize mental health programs directed to college students, as well as the forms of interventions offered to reduce the incidence of psychological disorders. From the proposal, a survey was conducted in the databases Scopus, Lilacs, and the repository Alicia, in the period between 2010 and 2021, choosing the search phrase “Programas de saúde mental para universitários” in Portuguese, “Mental health projects for university students” in English, and “Proyectos en salud mental para estudiantes universitarios” in Spanish. The research areas spanned humanities and social sciences, with peer-revie...

Debido a los constantes deslizamientos que se producen en lugares cercanos a la zona de estudio, especialmente en épocas de invierno, nos llevó a realizar un estudio más detallado y minucioso acerca de la estabilidad de taludes en roca entre los kilómetros 95 al 97 de la carretera Ciudad de Dios - Cajamarca. Es por ello que la presente tesis se encargará de informar al gobierno central y a la población aledaña si realmente se puede producir un deslizamiento en el tramo mencionado. Para poder llegar a un veredicto final se dividió en siete estaciones geomecánicas a la zona, en donde se calculó la cohesión y ángulo de fricción interno de la roca mediante el criterio de rotura de Barton - Bandis, se analizó la cinemática de los taludes, a ello se sumó el cálculo de la densidad de las unidades litológicas aflorantes y finalmente los datos obtenidos se ingresaron a los softw...

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...
