Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. Today, it remains a challenge for data mining to make its algorithms and applications equally efficient in the need of increasing data size and dimensionality [1]. To achieve this goal, many applications rely on parallelism, because it is an area that allows the reduction of cost depending on the execution time of the algorithms because it takes advantage of the characteristics of current computer architectures to run several processes concurrently [2]. This paper proposes a parallel version of the FuzzyPred algorithm based on the amount of data that can be processed within each of the processing threads, synchronously and independently.

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.

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.

One of the factors that determine the productivity inside a company is the state of the machinery with which is counted for the production. Our objective was to design a system that allows the engineers to supervise and to evaluate the state of the machinery, so that this in sot only repaired when it doesn't work, but rather one has the possibility to take a periodic registration of the operation of the same one. With it, it'll be possible to identify the flaws of the machinery in their diverse evolutionary phases. This will allow to carry out an appropriate correction of the problem diminishing the maintenance cost and, therefore, to stop the machinery for a smaller period of time. The system that we have designed in compound for a card of acquisition that will allow to capture and to transfer the mechanical vibrations of the machinery toward analysis software that allows the engineers ...

In these times of pandemic, hospitals are being the focus of many innovations, not only for the adaptation to telemedicine, but also from the perspective of the use and processing of the multiple modalities of medical images, where we find images made up of a single Image such as x-rays, images that are made up of a sequence of images such as tomography and Magnetic Resonance, or in video format as is the case with ultrasound and angiography. One way of working with images is through popular image servers that connect to medical equipment for transfer and storage. In the process of visualization and processing, special workstations with good computational capacity are required for these purposes, in most cases these workstations are connected in the network of medical offices, therefore they are presented in a normal working image display requests at the same time. The methodology presen...

The article analyzes the urban leasing policy in contemporary Peru and seeks to explain the origin and permanence of contractual interventionism in urban leasing until the 21st century. All political periods are analyzed, from the governments of Augusto Leguía (1919-1930) to the governments of the last democratic transition (2000-2020) and it seeks to show very synthetically the multiple determinations of contractual interventionism. The analysis of public policy on urban leasing is developed within the framework of the contemporary Peruvian urbanization process, defined by the development of the so-called neighborhood as the way through which the urban popular sectors accessed housing from the decade from the fifties of the 20th century and how they were incorporated and integrated into the city; and the parallel weakening of the identification between slum, rental and housing of the u...

The daily electric demand in Peruvian National Interconnected System-SEIN- has very particular trend, seasonality and characteristics external effects, a situation that complicates the process of estimating the short-term forecast. The aim of this paper is to formulate and calculate ARIMA models with External Events Analysis to achieve efficient forecasts of electricity demand each day, at total level and broken down by areas of the SEIN. The methodology is based on treating each time series using appropriate statistical-mathematical transformations to achieve stability in variance as regular seasonal averages, parallel external events to try to reach an optimal predictive model ARIMA each area of the electrical system of Peru (Central, South and North) and for each day of the week. The results demonstrate the predictive efficiency. Taking as a quality indicator forecast the Mean Absolut...

This work illustrates the extent to which the work of Ricardo Palma, set in Ica, has been developing, over the course of time, the iqueñidad as a feeling and passion for the terroir. It is established how this identity process that begins in the first decades of the 20th century, parallel to the forging of Peruvianness, the supreme objective of Palma, achieves the birth and strengthening of the iqueñidad, which in the current time is expressed in a formidable explosion of elements that allow to verify that the cultural management, the artistic creation, the educational management, and others have associated themselves with the urgent need to strengthen Ica’s cultural identity.

El presente trabajo ilustra en qué medida la obra palmista, ambientada en Ica, ha venido gestando, con el transcurso del tiempo, la iqueñidad como sentimiento y pasión por el terruño. Se establece cómo este proceso identitario que se inicia en las primeras décadas del siglo XX, paralelamente a la forja de la peruanidad, objetivo supremo de Palma, logra el nacimiento y fortalecimiento de la iqueñidad, que en la hora actual se expresa en una eclosión formidable de elementos que permiten verificar que la gestión cultural, que la creación artística, que la gestión educativa, etc. se han asociado al impostergable fortalecimiento de la identidad cultural iqueña.

In the transition from a Fordist to a post-Fordist society, the constructive task of the semiotic production of the brand has tilted the functional-brand towards the emotional-brand. For this to occur, as a prerequisite prior to its commodification, a process of rationalization of the emotions described by Illouz has taken place, running parallel to those described by Weber in the sphere of organization of work, and by Adorno in the culture industry. This is exemplified by analyzing the commodification of leisure and tourism through the commercialisation of places.

The symbiotic relationship between human beings and the environment has evolved in parallel, leaving its mark on the genetic structure of our species and the formulation of social statutes. This convergence is evident in the dynamics of modern life, the functional aspects, and the emotional anchors. Based on the postulates of environmental psychology and design proposals, this article presents a model called “restorative urbanism”, stating that proximity to urban nature is a critical element in the composition and design of urban environments, fostering better perceptions of external habitability and improving individual and collective well-being in biopsychosocial terms through the environmental restoration process, achieving urban-environmental and psychological sustainability. The importance of the proposal lies in its ability to question how the morphological characteristics of t...
