Our location in the world makes us a country with a high seismic risk. Taking into account that the information produced during a seismic event is of vital importance for the study carried out by seismology, it is necessary to use the appropriate type of instrumentation to record these data. Currently, electronics provides the necessary technology for the study of phenomena of this type. The design and construction of a Digital Accelerograph will allow us to carry out a detailed study of a seismic movement and the effect caused on the structure of buildings. Finally, we can say that the construction of an instrument of this type at a low cost will allow repowering and increasing the CISMID accelerographic network and, in general, improve the knowledge of seismic phenomena at the national level.

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 ...

Modern studies have shown that mirrow neurons are involved in the development of social empathy and language. Consequently, deficiency in mirror neural networks response could be one of the dysfunctions present in autistic spectrum disorder (ASD), as a phenotypic functional expression of channelopathies in some brain regions.Early detection of deficiencies in mirror neural network systems could allow more efficient applications of behavioral therapies in patients with ASD. The detection of MU waves in the electroencephalogram (EEG) could be an interesting technique that refers to the functioning of these neural networks.In this article we present a simple technique, developed with the purpose of identifying the presence of MU waves in the EEG record. It consists of a processing that analyzes each one of the derivations of the EEG, with the implementation of a mathematical method. The sig...

The need to develop a BCI brain- computer interface system for the control of a robotic arm in Peru arises from the possibility of interconnecting the human nervous system with a robotic or mechatronic system, and using this concept to recover some motor function. Brain Computer Interface (BCI) is a communication system based on the recording of brain signals (EEG). The electroencephalogram is the basis and support of the BCI technology. It is a novel technology that allows human-machine interaction in a virtual or physical environment, through a communication channel between the central nervous system and a robotic device. In recent years, the aforementioned systems have caused the interest of important research centers worldwide.

Los dispositivos de radio tradicionales tienen una funcionalidad limitada que solo puede modificarse haciendo cambios en el hardware. En este sentido, cualquier mejora en la flexibilidad de un dispositivo de radio tradicional implica un aumento considerable en los costos de producción. Por otro lado, los sistemas de radio definidos por software (SDR) proporcionan una solución relativamente económica y efectiva, permitiendo múltiples funcionalidades que pueden mejorarse simplemente actualizando el software. El presente informe describe la implementación de cuatro sistemas SDR mediante el uso de una computadora portátil con el software GNURadio, una placa transmisora de RF y un dispositivo receptor de RF de bajo costo. Este trabajo se centra en el diseño de transmisores y receptores que pueden realizar técnicas de modulación para señal analógica (FM) y señal digital (QPSK).

La robótica teleoperada en los últimos años ha demostrado ser un valioso apoyo en tareas de EOD; una mejora notable en los sistemas que controlan estos robots han sido las Interfaces Naturales de Usuario (NUI); sin embargo, la investigación que implementa este tipo de sistemas no se centra en la estabilidad de los movimientos del brazo robótico, necesaria para este tipo de aplicaciones debido al peligro que supone trabajar con explosivos. En este trabajo, proponemos la implementación de un Procesamiento Óptimo de Señales para una interfaz NUI basada en el controlador Leap Motion (LM). El objetivo principal de esta investigación es identificar correctamente los movimientos intencionados del operador, conseguir una alta estabilidad de la pinza robótica y suprimir los temblores fisiológicos de la mano del operador, considerando no aumentar la carga de trabajo mental y no disminui...

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.

Aunque las señales electromiográficas superficiales son la señal de entrada más común para los algoritmos de aprendizaje automático en aplicaciones de reconocimiento de gestos de la mano y estimación de la fuerza del dedo, sólo hay unos pocos sistemas disponibles comercialmente para la adquisición de EMG superficial. Este trabajo propone una matriz de electrodos superficiales seca, barata y fácil de fabricar. Este sistema utiliza múltiples sensores diferenciales activos integrados en una pequeña placa de circuito impreso de doble capa, cada uno de los cuales utiliza dos pequeñas áreas rectangulares de la capa inferior como capa conductora para la adquisición de la señal. Con una ganancia diferencial de 60dB entre 23 y 3000Hz y una relación de rechazo de modo común de -60dB a 60Hz. Se presentan los criterios de diseño y las simulaciones.

This article describes the procedure for implementing a graphical user interface using the App Designer development environment and the Signal Processing Toolbox of Matlab software, to reinforce the teaching of analysis in the domain of time and frequency of periodic and typical signals used in the subject Digital Signal Processing, which belongs to the Electronic Engineering Program of the Ricardo Palma University, Lima, Peru. Likewise, said interface was developed using various components such as DropDown, Button, Knob, Axes, Slider, among others, which allowed the choice of the type of signal from a list, choice of the sampling frequency and the percentage of overlap as well as the size of the window to segment the temporary signal, and in the same way the temporal, frequency and temporal graphic representation- frequency. In this way, the source code of the implementation of the grap...

La idea de escribir un libro con temas atinentes a la Acústica surgió como proyecto a la finalización del evento «Día internacional de conocimiento de los problemas del ruido. INAD2024-Perú», que se realizó en el marco del International Noise Awareness Day en el auditorio «Los Caynas» de la sede Los Olivos de la Universidad César Vallejo de Perú, con el objetivo de tener material teórico –que nace de la práctica profesional– para compartir las experiencias de los conferencistas que participaron en dicho evento, ya que no es usual encontrar literatura que compile las reflexiones que surgen de la realidad, por lo que este libro titulado «Acústica - Una visión interdisciplinaria. Reflexiones y soluciones para una sociedad más saludable», tiene la intención de cubrir ese faltante y que además tiene un valor agregado: Es el primer libro genuino con temas de Acústica ...

Esta Tesis se enfoca en los entrenamientos de tiro de 300 metros con francotiradores. Actualmente, se dispone de dispositivos para estimar la ubicación del impacto de un proyectil en un blanco de tiro, optimizando así el tiempo en los entrenamientos libres. Sin embargo, estos dispositivos no poseen una precisión y exactitud óptimas, debido a que su diseño está basado en un modelamiento ideal, utilizando un valor constante de 343 m/s para la velocidad del sonido, lo cual es inexacto. Según estudios realizados, la velocidad del sonido depende principalmente de variables medioambientales como la temperatura y la humedad relativa. Por ello, en esta Tesis se realizó el modelamiento de un sistema de detección de impacto de proyectiles basado en el análisis de datos, utilizando los métodos de modelamiento RCAPE (Regresion Causal Asociativa Ponderada Exponencialmente), regresión back...

This paper presents a noise reduction method for electrocardiographic (ECG) signals with real-time application. The method was evaluated using digitized signals with resolutions of 14, 16, and 24 bits, durations ranging from 30 to 60 seconds, and a sampling frequency of 1000 Hz. Prior to its application, power line interference (220V/60Hz) is attenuated if present. The approach is based on signal decomposition via the Stationary Wavelet Transform (SWT), analyzing 10 detail levels and 10 approximation levels. It was identified that noise is primarily concentrated in the first four levels, occasionally extending to the fifth. To differentiate between useful signal and noise, histograms of the detail coefficients were analyzed, and key metrics such as kurtosis, relative wavelet energy (RWE), and standard deviation were computed to establish adaptive thresholds for effective noise removal. T...

The process of hydrolysis was carried out on a suspension of quinoa flour in water in a proportion of 1 in10 parts of water, previously gelatinized, to which was added an equivalent suspension of enzymes of 1,5 g/1000 g (50% of alpha amylase and 50% protease). With that, proteins were solubilized and starch was reduced to reducing su- gars, obtaining a liquid product at an average concentration of 8,5% that was later con- centrated to 45% of total solids. The hydrolysis process allows, on the basis of 1 kg of quinoa flour, toobtain80 to 85% of hydrolyzed material from20 to 15% of cellulosic residue, proteins and carbohydrates, non-digestible by the enzymes. The experiences that were carried out brought as results the following optimum values of kinetic parameters: Concentration of substrate: 10,0 %; Temperature: 60 ºC; pH: 5,0 and enzyme con- cent...
