Monoculture in a computer network is defined as executing the same protocols and software on all the networking devices. Multiple, correlated failures may be triggered in a monoculture network by attacks that exploit existing vulnerabilities in either protocols, software, or hardware. In this paper, optimal multiculture network design is used to improve the network reliability in the presence of correlated...
Cognitive Radio has been proposed as a solution to the spectrum underutilization problem in Wireless Sensor Networks. This paper describes most used cooperative and non-cooperative sensing techniques in Cognitive Radio Sensor Networks. Energy detection is an optimal method when no prior information about primary signal is available. However, most of the contribution focus on the cooperative sensing...
Nowadays, there are several effective computational intelligence techniques that, theoretically, could be useful to classify human daily life actions. Moreover, sensors are getting smaller, cheaper, portable and even wearable. In this paper, we have built an annotation tool by applying several computational intelligence techniques (K-Nearest Neighbor, the Support Vector Machine and the Multilayer...
In this paper we present an optimization algorithm for simultaneously detecting video freeze and obtaining the minimum number of the frame required in motion intention estimation for real time robust video stabilization on multirotor unmanned aerial vehicles. A combination of a filter and a threshold is used to the video freeze detection, and for optimizing the algorithm, we find the minimum number...
In this article, the efficiency of Kalman's filter to classify moving parts is shown. A SCARA robot working cell was designed and built to accomplish this task. The main goal is to classify parts that are being carried on a conveyor belt at constant speed according to their shape or color. The operation of the Kalman's filter is described, as well as the mathematical equations to develop the algorithm...
This paper analyzes the reverse link performance of wireless networks in presence of co-channel interference on AWGN and Rayleigh fading channels and M-QAM modulation schemes. Simple and precise close-form analytic expressions for mean symbol error probability are derived. The proposed expressions of the analytic model developed to evaluate the performance of those systems are verified by the results...
The following article presents the modeling and control of a refrigeration system for fruit preservation. The mathematical model developed is based on mass balance and energy balance. It has been developed in two blocks: analysis in the refrigeration components and analysis in the conservation chamber. In the refrigeration system the elements have been studied: compressor, condenser, expansion valve,...
The purpose of the paper is to add solutions to the recognition and transport of minerals copper mining in southern Ecuador, using tools that have MATLAB® and LabVIEW®. The algorithm developed in MATLAB® using the principles of image processing to segment and filters the same. Finally applies the theory of neuro-fuzzy for the recognition of the presence of copper in a rock that is modeled. Is important...
Vehicular ad hoc networks (VANETs) have emerged as a paradigm for sharing information among vehicles and infrastructure that has the potential to provide road safety and travellers comfort. The bandwidth limitation is one of the main challenges of this technology, however, the growing perspectives of applications demand more and more service channels. In this work we propose two novel channel hopping...
The biological treatment of industrial waste is a priority theme for the sustainable development of any society. In recent years, there has been a significant increase in the study of the efficiency and reduction of the energy costs of this process, as active sludge treatment plants are characterized by a high cost of aeration. This study aims at modeling an active sludge treatment plant based on...
The interferometry problem addresses the estimation of an unknown quantity exploiting the interference among measurements from different sources. These measurements are obtained from the Fourier domain but are sparse and contaminated with noise. We propose a parametric, sum-of-basis, model for these observations together with a Bayesian approach for reconstructing interferometry images. Our main contributions...
This paper proposes an algorithm for QRS-complex onset detection in single channel ECG signals based on the first differential of the ECG signal and an adaptive baseline estimation. The proposed algorithm was developed and tested using the Physionet QT Database. A 100% detection rate on the onset of the QRS complex, with a mean error±(standard deviation) of −0.48±(11.26) ms was achieved against the...
Localization is one of the main tasks of autonomous mobile robots. There are many approaches on how to determine the robot's position with reasonable precision, as with the use of sensor fusion (IMU, GPS, Image, LiDAR). Even though it is possible to achieve high precision with these sensors combined, a solution that requires less resources in terms of processing, energy consumption and yet provide...
The measurement of consumption of public services such as drinking water and electric energy, and information management is one of the problems facing intelligent cities. In this article we describe the design of a computer system that allows the management and administration of consumption records made by smart meters that communicate through MQTT using mobile telecommunications networks. The results...
Depending on the application, power and energy requirements may differ significantly and, most likely, a single lithium-ion cell will not suffice. Battery packs offer cell interconnections that allow to obtain several possible voltage and discharge current ratings. Typically, the battery packs are designed to meet the specifications of the application within a certain range, and sometimes they are...

The simulation resulted, that the...
The number of elderly people in the world is growing rapidly. For this reason, is necessary more tools for the care, entertainment, and interaction of this part of population. This paper presents the architecture that will take SAFER (“Smart Assistance platform For EldeRly care”). The objective of this platform is providing, in an integrated way, a set of smart services that improve the quality of...
Hypertension is one of leading causes of death worldwide; due to the absence of symptoms that alert about illness at its beginnings. This article proposes the experimental developing of a blood pressure monitoring device as an instrument for hypertension diagnostic based on oscilometric method. The blood pressure detection algorithm, correlates the pressure signal acquired by a transducer and the...
In this paper we present a case study emphasizing the proposal of a telecare system which might be implemented in the first attention level belonging to health centers of Periurban zones of Lima city. Concretely, the system relies entirely in an algorithm which is based on a mathematical scheme that models the behavior of the glucose in type 2 diabetes patients under episodes of binge eating disorder...
