title: Método de regresión polinomial aplicado a la estimación de la señal de referencia de un sistema de filtrado adaptativo por cancelación para el tratamiento del desplazamiento de la línea de base del electrocardiograma
description: The systems of leaked (filtered) adaptative consist principally of a sign of reference. From these two series of time, the system of leaked adaptative conditions his internal variables to obtain the wished response. In the specific case of a system of leaked adaptative for cancellation, there is needed the estimation of mathematical function that shapes the distortion that wants to avoid of the sign of entry. This article centres on the problem of removal of the displacement of the base line of the electrocardiogram (ECG) for which a system has been designed for the estimation of the sign of reference, by means of the method of polynominal regression, whisch takes different points of the electrocardiogram. The sign of estimated reference is applied to a system of leaked adaptative by cancellation for the base line of the ECCG.

Quantitative Model in Security Informatics Risk Assessment
type: item
description: This paper shows the importance of approaching in security Risk Assessment (RA) about Quantitative model in Risk Management. The RA has been calculated with qualitative method by different framework, for example: RISK IT FRAMEWORK (COBIT Component) [7], OCTAVE – ALLEGRO [8], MAGERIT V3 [9], FAIR [4], ISO 27005 [11], NIST800-30 [3]. All frameworks included in the scope the Risk Assessment; however this is more qualitative than quantitative. In this work, we propose a methodology to support the implementation and execution risk management, using quantitative risk assessment method. The methodology is based on three components: secure capture logs (apply networks forensic technical), likelihood risk or log analysis with logistic regression and risk assessment with influence diagrams.

Diseño de un reactor UASB de escala laboratorio y bajo costo para investigación y enseñanza en laboratorios de bajos ingresos
type: item
description: Los reactores anaerobios de manto de lodo de flujo ascendente (UASB) son el sistema más ampliamente implementado para el tratamiento anaerobio de aguas residuales de alto contenido de material orgánico. Aun cuando estos son sistemas altamente eficientes y la producción de metano a partir de agua residual los hace energéticamente atractivos, su implementación en países en desarrollo todavía está retrasada no solo debido a dificultades financieras, sino debido a que su operación es relativamente complicada. Por esta razón, es crucial mantener reactores UASB de escala laboratorio instalados, de manera que se puedan entrenar técnicos y profesionales en este campo. Desafortunadamente, los costos de instalación pueden ser prohibitivos para algunos laboratorios de bajos ingresos. Dado que la litera­tura científica usualmente hace énfasis en los resultados obtenidos usando reactores UASB, pero rara vez se enfoca en sus detalles de construcción, aquí se presenta una descripción detallada de la construcción de un reactor UASB de bajo costo para investigación y enseñanza en los laboratorios de ingeniería ambiental de la Universidad Antonio Nariño.

Methodology of design and hydrodynamic simulation of a Kaplan microturbine using computer tools
type: item
description: This paper evaluates a simulation model of a six blades Kaplan microtur­bine; with this, the effect caused by the pitch variation of the turbine when obtaining power at the output shaft is parametrically analyzed implement­ing different rotation speeds of the latter, related to the surrounding water flow. The geometry is simplified to reduce the processing time, discretiza­tion and the model analysis; the simulation was performed under defined boundary conditions and using computational fluid dynamics. With the data obtained, it was generated a series of 2D and 3D performance curves, that allows to characterize the behavior of the Ka plan microturbine, taking into account the inclination of the blades and the impeller rotation speed, in order to determine the operation ranges in which the highest power output is obtained.

GIS in assessing of landslide susceptibility and structural systems
type: item
description: Currently, geographic information systems (GIS) are a fundamental tool in the capture, processing, analysis and dissemination of spatial data. Geo­technical and structural engineering, where the characterization of mate­rials and structures is important, GIS facilitate the inclusion of descriptive data called attributes to spatial or geographic records. In this paper two applications of this type of mapping is processing; The first has to do with the evaluation of susceptibility to landslide phenomena where two meth­odologies that divide the study area into cells of defined size are applied, GIS processing information from data capture to the generation of outputs graphs. The second application is geared towards identifying and analyzing the different structural systems, where the assessment of structural aspects contained performed in the Standard Seismic Resistant 2010 (NSR-10), the data are collected and included in the GIS systematically, in order that they are part of the attributes of each building represented by a polygon. The two applications are developed in the city of Tunja, Boyacá and intended to be part of a preliminary study of seismic vulnerability to substantiate a study of micro-zoning, necessary for the city. Such applications were not developed in the city and generate useful cartographic database data in decision-making for the planning and distribution of resources on issues re­lated to seismic hazard and attention in areas of greatest vulnerability. How GIS appreciated facilitate processing of spatial and descriptive information and its importance in the analysis of spatial trends and characterization of geographic areas and buildings.

Dynamical brain connectivity markers in presymptomatic Alzheimer’s disease
type: item
description: Alzheimer's disease is the most prevalent cause of dementia generally with an onset after the 65 years. However, there are some genetic mutations that induce the onset of the neurocognitive symptoms before that age. The study of mutation carriers provides a unique opportunity to identify early preclinical changes related to Alzheimer's disease. The Event Related Potentials are a powerful tool used for the study of the neural substrates of cognitive function and deterioration. The connectivity analysis emerges as an alternative to the average approach typical in Event Related Potentials. In the current work two groups, mutation carriers and non-carriers, perform a memory task during Electroencephalography recording. Brain graphs are built at different time points using the directed Direct Transfer Function. Our results show how the dynamical study of the connectivity might help to detect neuronal changes in preclinical stage of Alzheimer's disease.

Optimization of tuning PID controllers under IAE criteria applied to thermal processes
type: item
description: Equations tuning for PID controllers integrated approach are widely used in industry. Have developed different types of tuning equationsincluding the most used is the IAE. In the literature several types of tuning equations are reported, but these look satisfactory operation of the control loop but not the optimal operation with a minimum value in the response of the controlled variable. In this research, the response is optimized when IAE equations tuning is used in PID controllers, which seeksto minimize the deviation of the controlled variable to the set point for regulatory control, in order to decrease the value of IAE, which is necessary in critical applications such as the paper industry, where the management of temperature deviation is critical for the final product quality

In the work is carried out a brief description of the protection commonly used in the distribution systems demonstrating as these they are not able to limit the fault to the smallest possible area, and of how that is possible using the recloser of Nulec working under the Loop Automation. Also, is proposed a work methodology that facilitates the design of this system of protection getting in the analyzed circuits the faults affect to the smallest number of clients.

Stability analysis of the adaptive fuzzy control system of the continuous casting process of steel of ACINOX – Las Tunas
type: item
description: Stability theory plays a central role in systems theory and engineering, is considered the most important qualitative property of linear control systems so if a system does not fulfill this condition, the rest of the specifications are meaningless. In fact, most system designs are aimed directly or indirectly to obtain stable systems to the point that it is senseless to speak of a control system if it is not stable. In dynamic systems, there are different types of stability problems and to analyze them, Lyapunov theory has a prominent place. In this paper the stability analysis of the control system is done in mold level with fuzzy adaptation process proposed for the continuous casting of steel factory Acinox Las Tunas, where will be applied first and the second Lyapunov’s methods.

Robust Visual Segmentation using RCrR Plane and Mahalanobis Distance
type: item
description: In this paper a robust algorithm against illumination changes for skin detection in images is proposed. A database with 50 controlled condition images and 50 without controlled conditions of people in frontal position showing face, hands and arms was used. Five algorithms to perform color correction are evaluated: Simple Correction with Green Channel, Color Channel Compression, Color Channel Expansion, Fixed Reference and Gamma Correction. And four algorithms for segmentation are evaluated as well: RGB Skin Color, Reference Histogram, Euclidean Distance and Mahalanobis Distance. The proposed algorithm uses the Fixed Reference method together with Gamma Correction for color correction and performs the skin segmentation based on an RCrR color plane, found by making the transformation of the images using RGB and YCbCr spaces, finally Mahalanobis Distance is used. An average sensitivity value of 99.36 % and specificity of 84.31 % were obtained as result.

Robot Socially assistive and for multimodal autonomous interaction
type: item
description: This paper presents the methods and techniques used to create a multimodal interaction robot. This multimodal interaction allow to the robot interact with multi – users at the same time. In order to facilitate common tasks in nondeterministic environments, where several people needs to interact, such as a classroom. It has created a socially assistive robot endowed with anthropomorphic and cognitive features that gives you a sense of realism to the user, namely the user thinks for a considerable period of time that really is interacting with a living being.
