Smart antennas are currently one of the most exploited fields in terms of wireless networks, allowing high data transmission capacities, this is achieved by focusing the radiation in the desired direction and adjusting to the environment and conditions in which communications are developed. Smart antennas employ a set of radiating and emitting and combining elements organized in the form of arrangements connected at a common point to guarantee the required power, the signals from these elements are combined to form a moving beam pattern that follows a pattern determined by the user or designer. The biggest challenge to apply smart antenna systems within the Electromagnetic energy harvesting in wireless communications is the ability of high frequency antennas to capture an adequate power level for energy harvesting and storage, therefore, a Great bandwidth to take advantage of various wavelengths present in the environment, such as 3G and WIFI frequencies (2.4 GHz). The consumption of energy within communication systems is considered a big problem and a challenge when carrying out implementations in media where the storage or recharging of the end terminals is complicated by their location, this trend grows with the presence of the Internet of the IoT things, where it is directly dependent on the construction of a large wireless network that allows everything to be interconnected, for this reason there are investigations in the 2.4 and 5.8 GHz bands and represents future work for the 5th Generation (5G) cell phone. The great possibility of collecting electromagnetic energy from densely populated urban areas becomes a great renewable source of power for communication devices for both existing Wi-Fi technology and new technologies such as the 5G network.

Modelo matemático basado en las técnicas de detección de bordes y propagación de texturas para restaurar imágenes fotográficas documentales RGB
(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Matemática Aplicada, 2021) Jordán Bolaños, Carlos Rodrigo; Gordón Gallegos, Carlos Diego
EXECUTIVE SUMMARY The restoration of RGB documentary photographic images, using a mathematical model based on two fundamental techniques texture propagation and edge detection seek to give balanced priority to the two techniques, that is, neither should prevail over the other, using the notation for image restoration: I = Image, ɸ = source region. It is the known region of the image, Ω = target region. It is the region to restore and 𝛿Ω = border. RGB (color) documentary photographic images focus on people and social groups, to show aspects of their daily lives and are born with the intention of capturing reality in a still image. Edge detection is a technique that facilitates the identification of image objects and therefore their recognition. If the purpose of edge detection algorithms is to obtain as a result an image where the pixels of those points of the original image where sudden changes in intensity are presented are highlighted. In this respect it is worth highlighting, among others, the techniques related to zero crossing (“Zero crossing”) and level set (“level set”). On the other hand, texture propagation is a technique that consists of building from a small sample image, a large image that preserves the structure of the sample. An important part of the model that is proposed in this work, consists in filling the image by pixels, first of all, you must count on the area to be restored is well defined so that the neighboring textures maintain balance and harmony in the final result. The proposed mathematical model is designed to obtain from the original image, first the gradient of the image followed by the extraction map which is nothing more than the silhouette of the object to be extracted; then the energy map of the image is created to proceed with the removal of seams. Seam after seam will be removed until you create a resulting image similar in size and characteristics to the original. Finally the restoration will be done considering the edges and textures of the original image, with this it will be evaluated if the restored documentary photographic image is visually satisfactory. The similarity criterion to make the comparison between the original and resulting image has to be of mathematical type, that is, an algorithm will compare pixel by pixel the two images showing on screen how efficient the algorithm is. Under the above context it is said that the restoration of images through mathematical modelling seeks to refine the amendment in an intelligent way, that is to say, that at the end of the restore process, the image is visually pleasing to the observer, where the subtraction of elements or the size modification does not harm the harmony of colors, shapes and textures.

This application was developed and implemented in Python with the SymPy and numpy libraries to use computer calculation. The results displayed by the application are based on fidelity with the theoretical development. In the second current scenario, there has been an immense advance in the field of wireless communications in this world of modern engineering. Today's softwaredefined radio (SDR) technology is an undisputed emerging technology and presents new challenges for communications engineers. The advancement of the SDR system has made significant progress in recent years, making it a substitute for traditional hardware radio architectures where mathematical procedures are required to decode and process radio signals using analog circuitry. Recently, computers have turned out to be powerful enough to do the required mathematical calculations using software. Therefore, the aim of this research project is to demonstrate that an RTL-SDR-based spectrum analyzer can be used competently as an alternative to the existing hardware spectrum analyzer. This approach will reduce the complexity of the analog hardware system with the greater manageability of software-based filtering and demodulation techniques. As RTL-SDR devices are relatively inexpensive (approximately $ 30) and small in size, this system also offers cost-effectiveness with the provision of portability. An experimental study was carried out with the appropriate conditions to examine the viability and efficiency of the proposed system. Basically this research project presents the implementation, testing of an application for the simulation of Fourier Trigonometric Series and a low-cost software-defined radio based on the Raspberry Pi4 computer, the RTL-SDR radio receiver and the GNU software.

Thanks to technological advances in recent years, the use of IoT devices has gradually increased due to the large number of applications in which they can be used, such as: home automation, smart vehicles, robotics, wireless sensor networks, among others. These devices, being mostly wireless, have one or more batteries as their main power source, which are responsible for supplying the necessary electrical energy to carry out their operations. However, the life expectancy of a battery is limited and is expressed as the number of charge/discharge cycles it can withstand, therefore it is necessary to find a permanent and more reliable source of energy. In order to solve this problem, a technology known as energy harvesting or energy harvesting has emerged, which consists of capturing the energy present in the environment and converting it into electrical energy. There are various sources of energy in the environment such as hydraulic, thermal, solar, wind, radio frequency, sound, movement, vibration, etc. For low power applications, the use of radiofrequency has been the object of study as a source for capturing energy thanks to the fact that this type of signals prevail in the environment, such as TV signals, radio, cell phones, satellite Wi-Fi, among others, however, the energy collected by this type of system is low in the range of millivolts, it is for this reason that in the present titling work a hybrid solar-radiofrequency energy collection system capable of continuously powering devices with 5G technology.
