Chapter
The classification of acoustic scenes has been gaining importance in recent years, either because of the applications that it may have or because of the challenge of implementing a computational tool that allows the proper detection of complex and diverse sounds, such as those presented in real environments. In this work a convolutional neuronal ne...
Chapter
The security in the transfer of Raster-type image data using different open computer networks has been extended in recent years, in order to avoid alterations of the information it is necessary to use different encryption methods of the Pixelated data. In order to carry out this purpose, it is required at least to fulfill two objectives in the encr...
Article
Context: The collection and storage of data on environmental variables in a coffee crop, through wireless sensor networks allow the transformation of said data and the application of a supervised learning model to establish its behavior. Method: For the present work, an architecture of 3 wireless sensor nodes was developed. Each node consists of a...

The use of the Internet has Reached a point in the world in Which it has Become essential in everyday life, the need to Have information at hand in the shortest possible time has generated a technological revolution That incurs the constant connection to this tool, from our Personal life to the same objects That we use in daily life, creating a nee...
Chapter
The vulnerable population with motor and cognitive disabilities in our country confronts daily to endless number of situations that transgress its rights and possibilities to carry on a dignified life. This way we implement a prototype of a web application using Ajax, JSON and REST technologies with the aim to avoid overloads and response times in...
Chapter
Climate change has brought with it the increased risk of occurrence of natural disasters that generate a high economic and social detriment and even the loss of human lives, for this reason in the last decades governments have been worried with finding more efficient ways to prevent or mitigate the impact of natural disasters can cause, in this way...

... Con respecto al consumo, en la sociedad colombiana cada vez es mayor la demanda energética por parte de las grandes ciudades, dando lugar a una crisis en este sector (González, Ferro y Tarazona, 2014). Un incremento en la cantidad de habitantes, la construcción de nuevas urbanizaciones y el aumento en el número de aparatos eléctricos en el hogar, producto del gran avance tecnológico de los últimos años, han llevado a que en la última década el consumo residencial sea el destino del 40,6 % de la producción energética total del país, siendo este sector el de mayor participación por encima del industrial y comercial. ...
... En la Fig. 6, se presentan los esquemas de modulación en los cuales se han trabajado como productos de investigación para el diseño, análisis e implementación para la estación terrena Cubesat-UD datos obtenidos hasta el año 2017, producción desarrollada por grupo de investigación GITEM++ con un total de 45 productos, resulta interesante analizar que el esquema de modulación más pertinente para la estación terrena Cubesat-UD según estos productos es FSK con el 36% de la totalidad de resultados obtenidos, apoyándose en aspectos tanto teóricos como investigaciones en proceso de comunicaciones, estos productos también son el resultado de desarrollar e innovar en el diseño de la estación terrena utilizando especificaciones de conexión establecidas por redes satelitales internacionales, las cuales definían como uso obligatorio el esquema de modulación FSK dadas sus ventajas de implementación de bajo costo, puesto que tiene cierta afinidad con esquemas de modulación analógico como FM (Ferro y Espindola, 2013) que modula mediante el cambio de frecuencia de la señal portadora a fin de obtener un ancho de banda más amplio, suficiente para la transmisión de la información que la estación terrena Cubesat-UD necesita (Adnan et al., 2016). ...
