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.

In the present article, I propose some initial topics for the typological-comparative study of semantic parallelism, which also serve as an analytical axis to study semantic parallelism in traditional kakataibo chants. These basic topics are the structure of the cotext, lexical and grammatical type of parallel units, type of semantic relations between parallel units, number of parallel units per pair of lines, and associated phenomena such as recurrent or fixed pairing and diphrasism. Following this initial proposal, I postulate that the cotext in Kakataibo semantic parallelism is a repeated morphosyntactic structure that does not exhibit ellipsis or increasing, the number of parallel units can be one to three slots and one pair is more productive, parallel units are related by semantic fields such as kinship terms and colors. Furthermore, I analyze the interaction of semantic parallelis...

The study had the objective of analyzing the psychometric properties of the Brief Academic Procrastination Scale (EBPA-16). The sample was non-probabilistic and intentional, represented by 478 university students (59.8% women and 40.2% men) from Lima Sur, aged between 18 and 33 years. The study was of the instrumental type, where the EBPA-16 was constructed and applied, made up of 16 items distributed in two dimensions, with a Lickert-type response scale with 5 response options. The results demonstrated the presence of content validity due to Aiken’s V values greater than .80. Homogeneity indices were found in the items (ritc >.20) and multicollinearity was rejected (ritc <.95). For the analysis of the validity based on the internal structure, the existence of a two-dimensional model was demonstrated by means of the AFE with a Pearson correlation matrix and a dimensionality...

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.

ABSTRACT This research explored evidences of internal structure and convergent validity as well as reliability of a Spanish version of the Experiences in Close Relationships-Revised (ECR-R) in Peruvian college students. Exploratory and confirmatory factor analyses were carried out sequentially in two randomly assigned sub-groups (n = 289, n = 301). Horn’s parallel analysis and exploratory factor analysis performed with the first subgroup found a structure of three factors (anxiety, avoidance directly measured and avoidance inversely measured). Then, confirmatory factor analysis carried out with the second sub-group replicated a three-factor model with acceptable adjustment indices. Each dimension showed good internal consistency trough Cronbach’s alpha coefficient. The results partially support convergent validity of the ECR-R with the Relationship Questionnaire. Finally, a 27-item S...

In Peru the growth of the informal economy is associated to the population’s growth, the scarce growth of the economy and the shortage of work sources. It is calculated that the informal economy in our country is equivalent to 35% of the PBI and 60% of work. The informal economy is not an exclusive phenomenon of the developing countries. Today the globalization of the economy has evidenced that the practice of producing wealth and creating employment outside of the legal context is also a phenomenon of the developed world. The magnitude of the informal economy in the developing countries and in the developed countries doesn’t appear in the official statistics of the Bills, for what it is ignored with accuracy its measure and incidence on the National Economy, what constitutes a great limitation in the design of the economical policies, the fiscal policies and the tributary policies a...

The principle of exhaustion of rights is one of the most discussed matters in intellectual property law, forming part of a debate that has not culminated in a global agreement. However, its application is present in all countries and the evaluation of its scope has deserved the attention of the doctrine and the courts of justice of the world. This work focuses on the field of trademarks and tries to show a gene ral perspective on the exhaustion of the right in its presence in international trade, through parallel imports. Likewise, it includes some of the economic reasons that support the existence or restriction of parallel imports, as well as an analysis of their regulation in international trade law.

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 ...

Three sets of geoglyphs present in the Paracas and Nasca desert areas are associated with the Andean myth of the Fox in the Sky. A discoursive parallelism has been identified between the geoglyphs and the myth, establishing the geoglyphs as graphycally rendering scenes of the myth in two cases. In the third case, the characters are present but dispersed. The myth narrates the trip of the two main characters, the Fox and the Condor to the skies. They are later joined by the Parrot. The result of the mythical actions is the apparition of vegetable species on Earth, especially the oca. These edibles are also delineated on the Nasca Plains. These geoglyphic sets have been produced, in different styles in the places mentioned, in succesive periods. The myth, found from the Peruvian Central Andes to the Northern areas of Argentina and Chile, is still narrated today.

The upgrade program of the Large Hadron Collider (LHC) was implemented during the second Long Shutdown program (2019/2020). For this program, the ALICE Collaboration (A Large Ion Collider Experiment) proposed, among others, a new detector called Muon Forward Tracker (MFT). The primary goal of the MFT detector, installed on December 2021 and located between the Inner Tracker System (ITS) and the Muon Spectrometer, is to improve the capability of vertex reconstruction. The MFT is equipped with the same pixel sensors used for the ITS upgrade. These sensors are the ALICE Pixel Detectors (ALPIDE), a kind of monolithic active pixel sensor. The MFT is composed of five arrays of pixel sensors which are configured as parallel discs covering −3.6 < η < −2.45. Some prototypes were designed in order to achieve the final version of the ALPIDE, such as the pALPIDE family, which was divided into t...

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...
