This article describes the procedure for the implementation of a graphical user interface using the App Designer development environment of the Matlab software and its Toolbox Signal Processing and Symbolic Math, which allowed obtaining the Fourier Series coefficients for seven periodic signals followed by a graphical representation in the domain of time and frequency through pulses. Likewise, this interface was implemented using various components such as Drop Down, Button, Knob, Axes, among others, which allowed the choice of the number of sinusoidal components used in the decomposition, as well as the choice of the type of signal, its amplitude, frequency, DC level and duration time of the same. Therefore, this implementation complements the teaching-learning process developed remotely for a topic in the Telecommunications I course of the 6th academic semester of the Electronic ...

The purpose of this work is to implement an algorithm to identify the seismic waves parameters: P phase, S phase, amplitude, period and duration. For this, digital signal processing and the programming language Matlab will be applied to perform the automatic reading of seismic signal parameters. As mathematical tools, the discrete Fourier transform (fft) to study the frecuency components of the signal and the Hilbert transform to obtain the envelope signal, will be used. A graphical user interface in Matlab was designed and implemented for reading (with functions of automatic reading or manual reading) seismic signals with three components. In this way, it makes easy the routine of reading the seismic signals within a great set. The results of the automatic algorithm agree with that of a manual operator for a great Signal/Noise ratio.

This article describes the fundamentals of digital image digital processing using a free-access, web user interface called Octave-Online. This interface is part of the GNU operating system software applications, as well as it is known as the equivalent of Matlab in free versión; for this reason, this tool was chosen in order to give a practical approach to the use of ten basic techniques of spatial processing of digital images. To do this, we started by collecting 8 files with image contents in JPG and with different characteristics such as high and low contrast, high and low frequency, shades of gray, and intensity of colors, to put the proposed processing techniques into practice. Subsequently, some guidelines were provided for access, upload of JPG files, creation of * .m extension files, and knowledge of certain tools offered by the Octave-Online web user in...

Los sistemas de comunicaciones inalámbricas por radio han avanzado vertiginosamente, pero presentan problemas de incompatibilidad entre los fabricantes de equipos, tecnologías utilizadas y protocolos de comunicación, lo cual limita o restringe la migración entre tecnologías y equipos físicos (hardware). Una solución para el problema de incompatibilidad son los sistemas SDR (Radio Definida por Software), consiste en dispositivos configurables por software. En este sistema, los componentes normalmente son implementado por un hardware (ejemplos como moduladores mezcladores, filtros, amplificadores, demoduladores, detectores, etc.,) y también con la implementan utilizando software en una computadora (u otro tipo de procesador digital). Esta tecnología resulta versátil y de bajo costo, puesto que los sistemas de software pueden ser desarrollados en procesadores de uso general y de b...

El objetivo de este trabajo de investigación permite dar a conocer la programación es un proceso por el cual podemos procesar datos para obtener un resultado (mediante un computador). Las instrucciones que le damos nosotros a la computadora es lo que solemos llamar programación. En sus inicios, la programación era posible gracias al uso de las tarjetas perforadas. El uso de cables o códigos binarios y todo este proceso era mecánico, motivo por el cual se habla de lenguajes de alto y bajo nivel. Hay que tener en cuenta que la programación es una forma de idioma y su lenguaje sería lo que conocemos como pseudocódigos, que es usando entre los seres humanos y las máquinas para comunicarnos y proporcionarles órdenes e instrucciones a las máquinas. Para poder hacer uso de los lenguajes de programación se debe tener conocimiento de la estructura, ya que son secuencias a seguir al m...

This paper proposes a procedure to minimize electrical losses present in industrial systems, through a specific program developed for this purpose, based on Genetic Algorithm, and written using MATLAB instructions.The minimization is realized with the placement of shunt capacitors connected to the buses. For validation of the proposed method, it is considered accuracy and speed, and the developed program´s results are compared with the results produced by traditional programs. The program avoids leading power factor at the bus connected with the power distribution company and the user may determine buses where he does not want the installation of capacitors. The Genetic Algorithm's fitness, responsible for guiding the optimization process, is the active power loss. Finally, the program is applied to minimize active losses present at an industrial system, 38 buses.

This paper is focused on creation a program to simulate the dynamic behavior of a reactor of tank with constant reaction which initials in English it is CSTR (Continuous Stirred Tank Reactor), and is considered as a complete mixture and, therefore, it is assumed that their properties are uniform throughout the reactor in which the exothermic reaction takes place of the ethyl acetate saponification with sodium hydroxide. In building the software program used MATLAB and Simulink. For the simulation of the saponification reaction are introduced initial concentrations of ethyl acetate and sodium hydroxide, and the constant temperature jacketing system of CSTR reactor. Next, consideration of the user, changes the data set of variables to simulate and observe, through graphs, the concentrations of ethyl acetate, sodium hydroxide, sodium acetate and ethyl alcohol function of time of the process...

In multigroup hydroelectric plant operating at partial loads, the maximum each group efficiency and the random combination of these, differ from the design efficiency of the plant at full load. These plants are conditioned to operate at partial loads, both in times of drought and periods of oversupply national electric grid. The period of drought in Peru is nine months per year, a situation that involves economic losses due to inadequate flow regulation and group choice efficiencies conditions below their optimum values. The aim of this work is the development optimizing efficiency process of a multigroup hydroelectric power plant, for any level of power generated in the daily interconnected generation program. The results are maximizing turbine efficiency and combined-group for each power output of the plant, outside its nominal conditions, also a computer program is constructed in Matl...
