Since different publication formats are designed to reach various audiences, they often undergo different review procedures, and have widely different impact. Ultimately, however, papers and publications are judged by their relevance, readership and citations they acquire. Bibliometric impact measures for journals and for individuals as expressed by Impact Factor and other indicators are reviewed...
One of the main drawbacks of the implementation of predictive control in a direct matrix converter is the high computational cost and the adequate selection of weighting factors in order to control both input and output sides. In this paper is proposed an indirect model predictive current control strategy enhanced with a fixed switching predictive strategy and an active damping implementation. With...
Technological knowledge and human capital in the last decades have gathered momentum at world sphere with a significant impact on the sustainable development of the nations through the renewable energies, specifically, with the use of solar energy, which can become useful energy forms such as electricity through a photovoltaic system. Its implementation has increased in places that are located away...
Today, power systems face new challenges in different fields, such as economic, social, environmental and technical. In the technical field, a number of issues related to protection systems are recognized, due to the inclusion of distributed generation and microgrids, among other aspects. This paper presents a novel laboratory experience aimed at university students, with the objective of understanding...
In this written is presented the development of a didactic plant, of low cost, in which is possible to do practices of classic and advanced control. The variable to control is the luminous intensity, this equipment will strengthen the students' practice knowledge of careers related to the industrial control area. The implementation counts with an electric circuit, which has a smart sensor, an embedded...
Nowadays, life unfolds in a digitised world, in which, each person can have access to a huge amount of information through the use of Internet. In this situation, most of daily activities are being influenced by a new kind of society that allows ubiquitous and instantaneous interaction among its members. The creation of social platforms (SPs) has strengthened human relationships at such point that...
In this work, the design and implementation of a system to control a greenhouse is presented. This system is a control of the temperature, relative humidity, soil moisture and lighting variables inside a greenhouse. With these variables, a system is configured for a specific type of crops, using sensors, a micro controller Arduino and actuators selected by the user. The system allows maintaining the...
In this paper, we implemented a new McEliece encryption scheme, which consists of a optimal cyclic code to correct errors of burst. Replaces the matrix permutation by a random interleavers. In place of the vector of random error is used a vector of error that also helps to detect and correct errors of slip. This new scheme improves the confiability of the system and on the other hand increases the...
In a context of users increasingly demanding for the use of technology, organizations are continually challenged to present new strategies to improve their business activities. This forces them to be aligned on frameworks and models that help to adequately relate Information and Communication Technology (ICT) resources to the external and internal activities of the organization. The application of...
Acelerated development of new technologies of information and communication many processes have been optimized. Also, the integration of automation in the electric sector has caused a notable impact generating advanced mechanisms for the generation, transmission and distribution of electrical energy. In this sense, the systems of control and monitoring of electricity consumption represent an important...
A major drawback of orthogonal frequency division multiplexing (OFDM) is the frequency offset sensitivity. It mainly leads to inter-carrier interference, which can effectively be reduced by employing the pulse shaping filter method. In this manuscript, we present and then optimize the improved double-jump 1 (IDJ1) pulse for digital video broadcasting over cable 2 OFDM systems. Our function is finally...
In this work, the principal aim is establishing networks parameters of wireless sensor. These devices can transmit variables to monitoring the quality of tourist beaches in the Colombian Caribbean. We propose a methodology to choose the network elements and its technologies. We analysis data based on coverage and implement the prototype. We show that the maximum distance between nodes is 33 m at mesh...
This article presents a Monte Carlo-based analysis of the effects that random manufacturing errors produce on the radiation diagram of resonant slotted waveguide linear antennas. Positional and dimensional errors on the slots are considered. The study is performed using a tool implemented in MATLAB based on the Taylor synthesis of antenna parameters and the analysis of arrays and aperture models....
In 2015, Zheng & Carter warned that the Internet of Things (IoT) would have an exponential deployment in all types of industry in order to improve the efficiency and effectiveness of its operations. In the military sphere, it has not been different. The Ecuadorian Armed Forces are trying to equip their soldiers with IoT Technology to monitor and visualize in real time the state of health during...
After being aware of the high demand of vapor compression refrigeration systems for the conservation of agri-food and hydrobiological products and the high economic costs that the use of these systems produces, both academia and industry have carried out studies that have allowed them to develop advanced technologies in order to produce savings in energy consumption. These advances lie in the production...
The fruit export market in Chile lacks of an online system or procedure for quality control of export fruit, which considers the minimum mandatory parameters that different types of fruit must meet in order to be exportable to different destinations. To solve this problem, we designed an information system that allows the online control quality of export fruits during the different stages of the productive...
In this work we analyze the spectral emission of the flame emitted by burning biomass, of different species of wood such as Cypress, Fig, Olive and Pine. The analysis was carried out to distinguish the different species of wood sensing the compounds of Sodium and Potassium emitted at 582 nm and 780 nm. Also, a spectral analysis carried out for samples of wood at different contents of water. The results...
