At present, teaching programming to future teachers is superficial or is excluded from computer science curricular. Only programming fundamentals are taught during computer studies, and skills acquired during the training are not applied in practice. The aims of this article are 1) to develop a programming course for teacher training disciplines that are taught in training units of the Ammosov North-Eastern Federal University (NEFU), and 2) give recommendations to apply features of the programming language Python in the professional activities of future teachers. This work applies the iterative methodological approach to undertake the study in various groups of students of NEFU from 2016 to 2019. Quantitative and objective indicators are used. Results show which modules of Python are the most appropriate for students to study for their future professional teaching activities. The trainin...

This article presents the application of the non-parametric Random Forest method through supervised learning, as an extension of classification trees. The Random Forest algorithm arises as the grouping of several classification trees. Basically it randomly selects a number of variables with which each individual tree is constructed and predictions are made with these variables that will later be weighted through the calculation of the most voted class of these trees that were generated, to finally do the prediction by Random Forest. For the application, we worked with 3168 recorded voices, for which the results of an acoustic analysis are presented, registering variables such as frequency, spectrum, modulation, among others, seeking to obtain a pattern of identification and classification according to gender through a voice identifier. The data record used is in open access and can be do...

The incorporation of morphometric data into cladistic analyses poses methodological challenges, particularly in handling continuous characters and landmark configurations in matrices that include multiple individuals per taxon. Although the program TNT (Tree analysis using New Technology) has integrated functionalities for directly analysing continuous and morphogeometric characters, there remains a need for complementary tools that facilitate data preparation and processing. In this context, we present two open-source applications developed in Python: py_tps2tnt and py_tm2tnt. The former transforms TPS files containing multiple individuals per taxon, performs Procrustes alignments, calculates mean configurations, computes centroid size ranges, allows the selection of inter-landmark distances, and exports various types of data into TNT-compatible formats. The latter, py_tm2tnt, focuses o...

This paper describes the operationalization of López Chávez and Strassburger Frías' (2000) mathematical formula for lexical availability using the Python programming language. The methodology used is framed within a qualitative-explanatory approach of an illustrative nature, which allows us to observe how Python can be fully incorporated into lexical availability studies. Python significantly optimizes data processing, shortening the time required and facilitating analysis, as evidenced by the results.

GitHub is a platform that provides hosting for software development version control using Git. It features an application programming interface to allow the software to interact with the platform. The enormous quantity of information Hosted in GitHub may be useful to make studies about the current presence of development tools in the open-source software development community. However, the search engine has restrictions that make it impossible to issue complex queries to the platform. In this report, it is described as an object-oriented and extensible solution, named QuantityEr, to obtain the number of search results of complex queries to GitHub by using the inclusion-exclusion principle. The mathematical definitions, as well as related concepts, are presented. The mathematical model is discussed. The application of general design and used development tools are presented. Also, the resu...

Aborda el problema de identificación paramétrica de robots manipuladores, aplicando la mecánica analítica de Euler, utilizando las ecuaciones de Euler- Lagrange para modelar el comportamiento dinámico del robot péndulo, el robot de 2 gdl y 3 gdl. Se deducen nuevas propiedades matemáticas del modelo dinámico y de energía del brazo robot, dando origen a un regresor lineal de estimación paramétrica; se utiliza el algoritmo de mínimos cuadrados como esquema de identificación. Se presenta un nuevo esquema de control tipo hiperbólico con compensación de gravedad y fricción para resolver el problema de control de posición de los robots manipuladores en el espacio articular. A esta propuesta se respaldará con un análisis de estabilidad usando el método directo de Lyapunov para obtener un riguroso análisis de estabilidad asintótica global. Finalmente, se mostrará la platafo...

In the present’s paper studying a strategy for a typo of convex problem, we treat a linear programming problem whose coefficient of decision variables in the objective function has a nonlinear behavior. When the coefficients are constant the Simplex Method solves these problems without much difficulty, but when the coefficients are no longer constant and the Simplex does not work. We propose a technique that exploits the convex behavior of these coefficients and uses the theory of approximation by piecewise linear functions.

There is at present in Peru an important concern in the knowledge society to respond to the demands of the productive sector already that during these last decades the specialties in each college were introduced on the initiative of the teachers, without any study of the labor market or the needs of the different regions, nor of the contributions of the industrial engineers to secondary education directly or indirectly. Currently not enough to have manual skills, but a set of capabilities that graduates will enable them to solve problems and perform in different posts or create their own businesses. The current approach that gives the education for the job is not geared toward this.Throughout the development of the chapters you will find also the references on the requirements of the industry by people trained in certain skills and on the other hand will be able to appreciate the strong ...

The teaching-learning processes nowadays require pedagogical supports that allow the teacher to generate a space of real interaction from the classroom, for the student with his career; the training of professionals in earth sciences or engineering, must be accompanied by the teaching of computer programming, using high-level languages, free download and open source, as a resource applied to the solution of specific problems, presented in the stability of slopes. Here is shown a Python application to calculate and plot the factor of safety of a slope, through a Graphical User Interface (GUI), inserting: libraries, variables, functions and widgets of this language. The safety factor obtained by the application is 1.26, which coincides with that obtained by the manual procedure, the coordinate that plots the safety factor (Fs), to determine its sensitivity, as a function of the reciprocal ...

This research was aimed at determining to what extent factors prior to university admission, motivational factors, and institutional experiences explain the academic persistence of students in the University Leveling Term (CIU) at the Simon Bolivar University - Coastal Campus. An explanatory-type quantitative study was proposed, which involved a non-experimental cross-sectional retrospective causal relationship design. The sample consisted of 101 students (50.5% female) with an average age of 17.90 years (SD = 2.37). The study found a significant relationship between some variables explaining academic persistence, which were: a) having a lower orientation toward academic goals; b) a higher score on the maladaptive pattern; c) a higher score in the perception of the Mathematics professor’s evaluation; and d) a higher score in the final performance. This set of variables explains 56.4% o...

Este documento evalúa el impacto de un programa de crédito educativo sobre el tiempo necesario para concluir los estudios universitarios en una universidad grande en Perú. Los préstamos han sido entregados a estudiantes con bajos ingresos que muestran un desempeño académico satisfactorio. La decisión de aplicar o no por un préstamo depende de cada estudiante, por lo tanto el análisis de regresión simple podría fallar en la estimación de este impacto debido al problema del regresor endógeno. En este estudio se utiliza una aproximación de variables instrumentales, y se encuentra que los estudiantes con préstamos obtienen sus grados más rápidamente que similares estudiantes sin préstamo.

In the last decade the multicore processors had emerged with the comeback of the symmetric multiprocessing (SMP) after a long decade in which the based OpenMPI clusters had dominated the high performace processing world. Actually, we have in the market 2, 4 and 6 multicore processors; the Cell BE processors with a Power Processor Element (PPE) and 8 vectorial processors called Synergistic Processor Element (SPE), and graphics processors which have from 48 to 448 cores dedicated to numerical tasks. In the present work, we show our experience in the interaction with these processors, discussing the programming techniques and the future possibilities for making low cost numerical tasks.
