In this paper we present the modeling of a neuro-fuzzy system to be applied in the mix of paint from color model cyan, magenta and yellow (CMY). We aim to research an efficient method to get a specific hue color that is located within color wheel. The modeling is focused in to generate a wide gamma of colors to paint crafts like Panama Hats only with mentioned colors. Variables of the system are given by the frame and shape of selection of color. We use a fuzzy controller to generate the magnitude of the CMY percentages and a neural network to interpret the components to dosage the assigned color. Finally proceed data are used to develop an embedded controller under open source, the resulting color from the system is verified using different samples to determine the accuracy with selected color. © 2015 The Authors.

The proposed general the problem of optimization for motion planning of articulated SCARA robotic structures, whose trajectories are subject to constraints, the stated objective is to obtain a sequence of collision-free positions that connect an initial configuration with end using search strategies based on heuristics working space, for which we use the space of the configurations. In order to evaluate the performance of this algorithm, we generated, simulated different work environments and the subsequent display of the planned collision-free paths, applied to articulated SCARA robot. To corroborate this work later this algorithm is implemented on an FPGA allowing varying some basic features of the robot. © 2013 IEEE.

This paper presents a model in distributed parameters for a drying plant of cocoa beans. The plant is composed of a combustion chamber, an air fan thrust and a drying chamber integrated by a rotating cylinder. The model was developed in the EcosimPro® platform, in wich the process of simulation, sensitivity analysis and estimation of parameters were implemented. For the optimization and validation of the model were used real plant data. This research examines a valid alternative to artificial drying of cocoa beans. © 2015 IEEE.

This paper presents an experimental result on the measurement of the lobular radiation pattern of directional antennas (Yagi) obtained by applying a SDR (Software Defined Radio) system for the homologation and verification of the antenna performance. The measurement depends on the energy absorbed by the antenna when it is used to received a RF signal of short wave. © 2015 IEEE.

Sound source identification is an intrinsic process that helps people to interact with the environment around them, allowing to interpret the information transmitted by humans, animals and machines, for this reason, it is mimicked by different types of autonomous machines. This article presents the development and implementation of a new method to identify the origin of the sound source for a small robotic system based on three microphones, using two types of artificial neural network, the first one-ADALINE structure, used to obtain a noise environmental filter and the second one-BACKPROPAGATION's structure to identify the source sound in a range between 0 and 180 degrees employing. The identification based on differents tests permit us to have an error of 7% in the last stage. The present project was developed with NI MyRIO device and the software LabVIEW and Matlab. © 2016 IEEE.
Territorial development in three medium-sized cities Ecuadorian cities: Effect of local strategies in implementing the “national plan for good living” and the change in the productive matrix [Développement territorial dans trois villes moyennes en Equateur: Effet des stratégies locales dans la mise en oeuvre du «Plan National pour le Bien Vivre» et le changement de la matrice productive] [Desarrollo territorial en tres ciudades medias ecuatorianas: Efecto de las estrategias locales en la aplicación del Plan Nacional del «Buen vivir» y el cambio en la matriz productive]

This paper analyzes the strategies developed in three medium-sized cities of Ecuador in order to progress to the National Plan for Good Living and the change in the production model, the basic guidelines policy of the government of Rafael Correa. From an analysis that combines statistical data and previous studies with fieldwork and in depth interviews the aim of this paper is to see how evolved the economy, politics and society of the three cities in recent years. The interest of these case studies is that these cities are dependent of mining and the primary sector, which makes them archetypal examples of the primary-export model that the Correa´s government wishes to overcome. The evidence found point to an insufficient coordination between the local and national scales and a small progress of these strategies. © 2016, Universidad de Granada. All rights reserved.

This paper presents different ways to make lighting controls, a review of the various types of luminaires, lighting control modes and equipment used for the management of residential lighting. The goal of the management of lighting will be have a reduction in energy consumption and an increase in the useful life of the luminaries. To analyze the energy consumption of dimmers for lights was used equipment for power measurements; with this data was obtained algorithms behavior of the power consumed in relation to the rates of attenuation, thereby being able to predict the energy savings according attenuation of the luminaries. Finally it was concluded that the savings in paying the electricity bill is directly proportional to the level of attenuation of the luminaries. © 2013 IEEE.

The high mobility and variability of road traffic has hampered the design of efficient communication protocols and the deployment of new services in vehicular networks. Nevertheless, the newly-introduced notion of virtual mobile nodes (VMNs) has the potential to turn wireless ad hoc networks into more predictable environments, facing the significant challenges raised by the mobility of the (real) nodes. Several studies on the applicability and benefits of using VMNs in the realm of mobile ad hoc networks (MANETs) have been reported in the literature. However, they always consider simple scenarios of static (i.e. non-mobile) virtual nodes arranged in grids over a given area. In this paper, we present experiments with virtual nodes in the more specific realm of vehicular ad hoc networks (VANETs), which allow us to explore alternative arrangements and new strategies of mobility for VMNs. We present the architecture of a simulation environment developed to assess these ideas, and discuss the settings and the results of preliminary experiments. © 2012 IEEE.

The integration of engineering and medicine in recent years has led to the development of technological innovations in the health field, that is why this area has been declared emergent in many countries and it has become a basic research discipline. In this paper we describe the experience in the academic support of the Electronic Engineering Department at the Salesian Polytechnic University of Cuenca for development projects of biomedical engineering from 2001 in order to establish guidelines to begin with the research group GIIB-UPS. The main objectives are to enrich the teaching and learning method in Biomedical Engineering, to strengthen the social appropriation of knowledge of the results of research around biomedical engineering in the University and to establish guidelines to begin the process of forming the first research group in this field in Ecuador. Based on results to date, we conclude that biomedical engineering education must ensure a positive work environment in which students will develop social sensibility with professional ethic and learn about the importance in their profession of multidisciplinary cooperation with professionals in the biomedical field. The proper progress of a research group requires time and planning for research training by lecturers and students. © 2012 IEEE.
