In recent years, the implementation of solar energy facilities has grown, as it is considered an environmentally friendly way to produce electricity. Solar energy can be exploited under different configurations or connection schemes. The most useful connection schemes are the string connection, the power optimizers and the microinverters. Microinverters have a wide advantage compared to the other schemes due to their ability to take advantage of solar energy under different environmental conditions, such as partial shading, temperature and irradiation. The implementation of microinverters has been slowed down because of its high cost and reduced lifetime. In general, the design of microinverters commonly includes elements such as transistors, electrolytic capacitors, sensors and a microcontroller. Electrolytic capacitors are commonly used as decoupling stages, even though they present a lower lifetime due to high frequencies of operation and current rises. In this paper, a new microinverter topology is presented, it uses a low-cost array of multilayer capacitors to filter high frequencies and get a low-cost topology.

The refrigeration systems are of great importance in the daily life of the human being, due to the fact that it is necessary to have cold storage systems for different processes and perishable products preservation. The generated electric power as an alternative source has been used for refrigeration systems involved in sustainable development programs. The aims of this research were to characterize a cooling system powered by solar panels and that pretend to improve the quality of life. Refrigerating machines that use alternative sources of energy contribute to sustainable development, however, those that do not use it have a greater environmental impact. The solar refrigerator prototype has a quantitative-qualitative approach in deductive processes based on interpretation and data collection. This was carried out using own materials for the refrigerators construction that allow obtaining a compact configuration, presenting, pressure-volume operation curves and autonomy of the system with maintenance similar to conventional refrigeration systems. The refrigeration system is intended to be used in marginalized areas, low-income organizations and in support unprotected populations.

Over time, wireless sensor networks (WSN) have been used for a variety of applications. Extensive work has been dedicated to various WSN applications. It is important to note that, due to their physical limitations, the sensors are prone to several types of faults. These restrictions can pose serious problems in event detection applications. Especially if the WSNs are deployed in hostile environments, such as the industrial or environmental sector. The detection of anomalies has recently attracted the attention of the scientific community, due to its relevance in real-world applications. The proposed solutions depend to a large extent on supervision and communication, using techniques based on tools such as Machine Learning and Neural Networks. In this context, we introduce the most commonly used anomaly detection techniques in WSN. Compiling and comparing the main methods applied in specific scenarios, we analyze the advantages and conveniences of using any of them.

The automation of processes today is one of the present needs in society as a result of the inefficiency that results from carrying out certain tasks without mechanisms that optimize them, whether due to time, efficiency, and in general All the technological progress that we already have, these mechanisms have become obsolete. This document shows a response to this situation, specifically focused on liquid management processes, the implementation of a Level Automated Monitoring and Control System for non-corrosive containers for domestic and commercial use. The adequate selection of the components that make up this system will allow its easy accessibility, with respect to the cost that this implies, its structure will be designed in such a way that it minimizes the execution time, that integrates more than one control, and that its interface Be as friendly as possible with the operator. This allows it to be an easy-to-use system, greatly improving the response time in its realization, as well as it will allow to have a greater control in the capacity of the level of the containers reducing in this way the expenditure of liquids that can be arouse by some carelessness.

The Development of edible films for the conservation of fungi (Pleurotus sp) emerged with the purpose of increasing the shelf life of food through the development and application of films based on candelilla wax. Five formulas were experimented, which were developed according to the proposed by Oregel et al. In 2016 with some modifications, the formula F1 (Guar Gum 0.8%, Candelilla Wax 0.2%, Glycerol 0.3%), F2 (Guar Gum 0.8%, Candelilla Wax 0.4%, Glycerol 0.2%), F3 (Guar Gum 1.2%, Wax 0.2% candelilla, 0.2% glycerol) and F4 (1.2% guar gum, 0.4% candelilla wax, Glycerol 0.3%) and F5 with the same proportion of F4 ingredients but with the addition of the three preservatives. The elaboration of the films was carried out in 2 stages of experimentation at T = 4 ° C and T = 30 ° C for 15 days. Characteristics such as texture, color and appearance were evaluated, the best evaluated formula was FB5 with a lifespan of ten days at T = 4 ° C, which allowed to increase the shelf life of the fresh product by a 100%.

Agriculture 4.0, conceived as a kind of industry, is built by integrating a set of digital technologies such as the Internet of things, Artificial Intelligence, and the management of large databases (or Big Data). This industry implies a transformation of the production infrastructure that allows increasing the agricultural productivity and the quality of the products efficiently and sustainably. These changes require the implementation of digital technologies for the collection, analysis and communication of information, allowing timely decision making. This article deals with the implementation of a platform that includes both desktop, Web and mobile applications and Internet of things tools for the control of production and marketing in avocado orchards. The development of a prototype of the platform is described under agile methodologies and following an iterative and incremental strategy. Finally, the tests that determine the integral functionality of the platform prototype and experimental results are presented.
