This paper proposes a methodology based on Analytical Hierarchical Process (AHP) and Fuzzy Inference Systems (FIS), to obtain a better selection of Enterprise Resource Planning (ERP). The company, which are going to acquire the software, bases this selection on their own imposed criteria and the ERPs alternatives based on some supplier's information. To select the most appropriate ERP, at the beginning, AHP was used. Then, Through a FIS is evaluated the selected ERP to know if it comply with the business financial and operational performance. Finally, another FIS fuses these results in an only one, which is called ”acceptability level”. The proposed methodology try to quantify all the subjectivity that involve an ERP acquisition by a business.

Everywhere in the world tax revenues are rolled back for the commonwealth to invest and finance goods and public services, such as: infrastructure, health, security and education. The predict income revenue (taxes) is one of the challenges that the Secretariat of the Federal Revenue of Brazil (RFB for its Portuguese acronym) has. This is an important challenge since the obtained information is valuable to support the decisions pertaining the federal government financial planning. In this work, it is introduced a hybrid model based on Genetic Algorithms (GAs) and Neural Networks (NNs) for a multi-step forecast of tax revenue collection. The results were more accurate in comparison to the outcome the RFB had estimated with the indicators method. The forecast results using endogenous and exogenous variables were divided into two parts: (i) in 2013 (validation period), there was obtained a Mean Absolute Percentage Error (MAPE) of 2.37% and a decrease of the Relative Error of 11.38% to 0.49%; (ii) in 2014 (testing data set) a decrease of Relative Error of 10.82% to 3.51% was obtained.

When learning different control related concepts and methods, simulation is often used as a training tool; but, it does not have some real time characteristics of implementation like dealing with coding and PC resources, supervision, and communications. In some cases, implementation cannot be carried away, since it involves hardware design and is expensive. The proposed solution in this paper involves low-cost Hardware-in-the-Loop for the Real Time Simulation of the plant or process to be controlled, a PC acting as a controller and a supervisor, and communications via Ethernet between the elements. It has the following advantages: new processes can be controlled by the PC without having to change the topology of the system; modifications on the plant or controller only require software changes; and has the potential of being extensible to a real system if the simulator software is changed to work as an Ethernet to analog decoder/transducer.

The present work proposes to recognize the static hand gestures taken under invariations features as scale, rotation, translation, illumination, noise and background. We use the alphabet of sign language of Peru (LSP). For this purpose, digital image processing techniques are used to eliminate or reduce noise, to improve the contrast under a variant illumination, to separate the hand from the background of the image and finally detect and cut the region containing the hand gesture. We use of convolutional neural networks (CNN) to classify the 24 hand gestures. Two CNN architectures were developed with different amounts of layers and parameters per layer. The tests showed that the first CNN has an accuracy of 95.37% and the second CNN has an accuracy of 96.20% in terms of recognition of the 24 static hand gestures using the database developed. We compared the two architectures developed in accuracy level for each type of invariance presented in this paper. We compared the two architectures developed and usual techniques of machine learning in results of accuracy.

This article presents the designing and construction of an electrohydraulic system controlled via the microcontroller ATmega328P and the Matlab software using the graphical programming environment Simulink by means of programmable blocks. These blocks achieve the communication through a COM serial port specifically configured for this task; this interaction allows the control of two hydraulic pistons connected to the system's platform, which enables the control of the platform displacement. Through this system, it is possible to reproduce seismic events registered in Lima during the last years.

Social conflicts in the world have increased, due to the fact that the natural resources is being over exploited. In this work, we conducted a social conflict analysis using the entropy-weight method, which is based on Shannon entropy theory. The case study was conducted on a mining project allocated in northern Peru. The rural population and urban population stakeholder groups were analyzed under seven social criteria or variables. The results revealed that the criterion most likely to generate social conflict between stakeholder groups was access to drinking water. These results could help to central and local governments to make the best decision in order to prevent possible social conflict. The entropy-weight method showed interesting results and could be applied to other social conflicts, as this method considers the uncertainty within its analysis.

The quality of electrocardiogram (ECG) signal is fundamental for reliable patient diagnosis. Reality is that ECG signal will be, in most cases, corrupted with electromagnetic interference (EMI) from several sources, mainly power-line. This type of interference can be reduced with different well-known methods like IIR (infinite impulse response) notch filters and adaptive cancelling algorithms. In this work, a 60 Hz interference cancellation algorithm is applied on real ECG data, which is processed in an embedded system built on STMicroelectronics STM32F401RE Cortex M4 microcontroller, and multichannel 24-bit ADS1298 (ADC) from Texas Instruments. The performance of this embedded algorithm is calculated as interference suppression (percentage) and extracted interference from a single ADS1298 channel.

This paper deals with the development of a V/F control of an induction motor with THD optimization using cascaded multilevel converters. The optimization algorithm was a genetic algorithm, which allows to obtain a voltage vs. frequency ratio (V/F) that decreases the voltage value as the frequency is reduced by maintaining the total harmonic distortion (THD) at levels very close to 0% over the entire frequency range of operation. The power converter is a common-source cascaded H-bridge multilevel inverter with maximum 15 steps per line voltage. The inverter was simulated by supplying a three-phase induction motor. The result of the simulations allows verify the optimization of the THD throughout all of the frequency operation range.
