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).

In current supply chains, the use of AIDC technologies allows the information that flows to be standardized and reliable, as well as obtaining a series of advantages related to saving time and costs. In Cuba, the use of these technologies is not regulated by national laws and most companies do not use them, considering ignorance of their effectiveness as the cause. This article analyzes AIDC technologies: specifically, bar code systems and radio frequency systems, their operation and benefits of their use in supply chains. Based on the existing need, a tool was designed based on a procedure that establishes a guide for the selection of technologies to be implemented in logistics processes. The tool designed is used for Case Studies to know its application and mode of use.

During years past, interactivity —as the audience's possibility to be on a certain way present on those communicative processes carried out by media— has been one of the most widely discussed aspects of media reality. This possibility isn't new news for radio. In fact, as mass media, radio has an exclusive series of features which stimulate, and even privilege, the incorporation of listeners in broadcast.

The radio, the very first electric mean of massive communication goes through technological changes facing new digital production processes and distribution of contents. These changes can be highlighted throughout the strategy used on the creation of audible content as well as on how it is accessed and consumed by users. Social sensitivity and practices on the digital radio scene are much different to the ones used on an earlier era. Thus, we propose understanding today as a moment of mutation for this media, a moment in which the digital era of the radio begins.

Mediante el uso de la tarjeta de sonido y la cámara web del computador personal se ha investigado la codificación de imágenes como patrones de sonido para permitir que las personas invidentes puedan interpretar la información de su entorno y desplazarse con mayor facilidad en esta. En todas las propuestas se ha codificado el tono de gris como volumen y las posiciones de los pixeles como frecuencias. Uno de los desarrollos denominado barrido manual equivale a «ver con el dedo» y permite que el invidente navegue sobre una pantalla sensible al tacto, auscultando la imagen para identificar su estructura.

The application of Artificial Intelligence (AI) is revolutionizing radio production, offering significant advantages over traditional methods. AI, much like digitalization did, challenges existing production structures and routines, forcing the industry to adapt to technological and market changes. This work identifies three types of AI: analytic, which detect patterns and foresee future situations; assistive, which execute mechanical tasks in an automated manner; and generative, which simulate creative processes and produce content. To contextualize the different functions, six phases have been established in the radio production cycle (Ideation, Research, Production, Distribution, Interaction, and Archiving), and in each phase, specific AI functions that contribute to the process have been identified. An inductive methodology based on the observation and analysis of 96 specific AI appl...

Computed tomography (CT) is a breakthrough technology used in medicine for diagnostic diseases. The same technique is used in other areas, such as aerospace chemistry, Radio astronomy, etc. The main objective of the CT is to reconstruct the internal part of an object without having to open it as a non-destructive test. To achieve this purpose, the CT uses the attention that X-rays undergo through this object with the information, the inner part of the object is reconstructed, that is to say the CT is an inverse problem.In this article uses the Fourier transform for the reconstruction of the internal part, for it is directly part of a continuous model, representing the density at the point (x, y) of a section, with a function p = p(x, y); and even though p is not required to be continuous, the Fourier method is more efficient and a better, more regular result is obtained p.
