Combined data mining approach for intrusion detection
(Scitepress, 2007)This paper presents the results of the project MIAU, a data mining approach for intrusion detection alert correlation. MIAU combines different data mining techniques in order to properly solve some existing problems in the ... -
Dialogue based management of user feedback in an autonomous preference learning system
(Scitepress, 2010)We present an enhanced method for user feedback in an autonomous learning system that includes a spoken dialogue system to manage the interactions between the users and the system. By means of a rule-based natural language ... -
Implementation analysis for a hybrid particle filter on an FPGA based smart camera
(Scitepress, 2010)Design and development of embedded devices which perform computer vision related task presents many challenges, many of which stem from attempting to fit the complexity of many higher level vision algorithms into the ... -
Multi-modal person detection and tracking from a mobile robot in a crowded environment
(Scitepress, 2011)This paper addresses multi-modal person detection and tracking using a 2D SICK Laser Range Finder and a visual camera from a mobile robot in a crowded and cluttered environment. A sequential approach in which the laser ... -
Correcting distortions of thin-walled machined parts by machine hammer peening
(Elsevier, 2023)Thin-walled aerostructural components frequently get distorted after the machining process. Reworking to correct distortions or eventually rejecting parts significantly increases the cost. This paper proposes a new approach ... -
Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ... -
Noise attenuation prediction and analysis in rectangular lined ducts
(ISMA, 2022)The noise of Heating, Ventilating and Air Conditioning (HVAC) systems is an important aspect when the comfort of the users is compromised. Thus, solutions to attenuate that noise need to be proposed. Linings in ducts are ... -
Damping characterisation of an elevator rope
(ISMA, 2022)The ropes of an elevator transmit the vibrations from the motor to the elevator car, and consequently have a great influence on comfort. Therefore, it is of major interest to analyse the dynamic behaviour of these elements. ... -
Data-driven energy resource planning for Smart Cities
(IEEE, 2020)Cities are growing and, therefore, the primary needs, such as the energy resources. Hence, managing them in the proper way becomes essential for a sustainable growth. This paper proposes a data-driven tool based on IoT ... -
Optimización de parámetros de CNC de acuerdo a criterios de productividad usando un modelo de máquina basado en redes neuronales
(Dyna Publishing, 2020)Every machine-tool user wants to maximize the productivity of their machines looking for balance between speed, precision and lifetime of mechanical components. Nevertheless, because CNCs have wide-ranging use, their correct ... -
Development of a novel method to characterize mean surface peak curvature as a signature of tribological performance of dental implant surfaces
(IOP Publishing, 2020)The integrity of dental implant surfaces might be compromised during surgical insertion. Wear and topographical modifications can occur during implant insertion, which can potentially have clinical implications. Accordingly, ... -
Links between circular economy and climate change mitigation in the built environment
(Elsevier, 2020)The construction sector represents one of the most significant sources of waste generation in the European Union (EU), with nearly one billion tonnes of construction and demolition waste annually. This sector also contributes ... -
An analytical model of through-thickness photopolymerisation of composites: Ultraviolet light transmission and curing kinetics
(Elsevier, 2020)In this paper, a kinetic model able to predict the evolution of the through-thickness degree of cure of ultraviolet (UV) cured composites has been developed and validated. The kinetic model, which is based on the autocatalytic ... -
Perfilado 4.0: ayuda a la puesta a punto y aseguramiento de la calidad en procesos de perfilado
(2019)Una problemática a la que se enfrentan las empresas de perfilado de chapa es la laboriosa, y con ello costosa, puesta a punto del proceso. En ella los operarios basan sus decisiones en experiencias pasadas y en la mayoría ... -
Impact of long-term resource variations on wave energy Farms: The Icelandic case
(Elsevier, 2020)Four decades (between 1979 and 2018) of the wave energy resource around Iceland are analysed in the present paper via the ERA5 reanalysis, the newest reanalysis of the European Centre for Medium-Range Weather Forecasts. ... -
Aproximación multimétodo para medir el impacto de los factores de diseño en la apropiación de un software de inteligencia competitiva
(Dyna, 2020)La industria 4.0 y una vida laboral en continua transmutación, plantean preguntas acerca de cuáles serán las competencias que requerirán las personas para la correcta apropiación tecnológica y la mejora del desempeño. Este ... -
Novel email spam detection method using sentiment analysis and personality recognition
(Oxford Academic, 2020)Unsolicited email campaigns remain as one of the biggest threats affecting millions of users per day. During the past years several techniques to detect unsolicited emails have been developed. This work provides means to ... -
A general approach to Software Product Line testing
(Sistedes: Sociedad de Ingeniería de Software y Tecnologías de Desarrollo de Software, 2019)Variability is a central concept in Software Product Lines (SPLs). It has been extensively studied how the SPL paradigm can improve both the efficiency of a company and the quality of products. Nevertheless, this brings ...
