Prototype of EN 301 549 Decision tree

The new European Standard EN 301 549 “Accessibility requirements suitable for public procurement of ICT products and services in Europe” is the response by CEN, CENELEC and ETSI to the European Commission’s Mandate 376. Today, ICT products and services are converging, and the boundaries between product categories are being constantly blurred. For that reason EN 301 549 has been drafted using a feature-based approach, instead of being based on product categories. The result is a standard that can be applied to any ICT product and service, by identifying applicable requirements depending on the features of the ICT. This demonstration presents ongoing work at the research group CETTICO of the Technical University of Madrid. CETTICO is developing a workgroup-based support tool where teams of people can annotate the result of performing a conformity assessment of a given ICT product or service according to the requirements of the EN. One of the functions of the tool is creating evaluation projects. During that task the user defines the features of the corresponding ICT product or service by answering questions presented by the tool. As a result of this process, the tool will create a list of applicable requirements and recommendations.

Simulating potential growth and yield of oil palm (Elaeis guineensis) with PALMSIM: Model description, evaluation and application.

Reducing the gap between water-limited potential yield and actual yield in oil palm production systems through intensification is seen as an important option for sustainably increasing palm oil production. Simulation models can play an important role in quantifying water-limited potential yield, and therefore the scope for intensification, but no oil palm model exists that is both simple enough and at the same time incorporates sufficient plant physiological knowledge to be generally applicable across sites with different growing conditions. The objectives of this study therefore were to develop a model (PALMSIM) that simulates, on a monthly time step, the potential growth of oil palm as determined by solar radiation and to evaluate model performance against measured oil palm yields under optimal water and nutrient management for a range of sites across Indonesia and Malaysia. The maximum observed yield in the field matches the corresponding simulated yield for dry bunch weight with a RMSE of 1.7 Mg ha?1 year?1 against an observed yield of 18.8 Mg ha?1. Sensitivity analysis showed that PALMSIM is robust: simulated changes in yield caused by modifying the parameters by 10% are comparable to other tree crop model evaluations. While we acknowledge that, depending on the soils and climatic environment, yields may be often water limited, we suggest a relatively simple physiological approach to simulate potential yield, which can be usefully applied to high rainfall environments and is considered as a first step in developing an oil palm model that also simulates water-limited potential yield. To illustrate the application possibil- ities of the model, PALMSIM was used to create a potential yield map for Indonesia and Malaysia by sim- ulating the growth and yield at a resolution of 0.1?. This map of potential yield is considered as a first step towards a decision support tool that can identify potentially productive, but at the moment degraded sites in Indonesia and Malaysia. ?

Automated end user-centred adaptation of web components through automated description logic-based reasoning

Context: This paper addresses one of the major end-user development (EUD) challenges, namely, how to pack today?s EUD support tools with composable elements. This would give end users better access to more components which they can use to build a solution tailored to their own needs. The success of later end-user software engineering (EUSE) activities largely depends on how many components each tool has and how adaptable components are to multiple problem domains. Objective: A system for automatically adapting heterogeneous components to a common development environment would offer a sizeable saving of time and resources within the EUD support tool construction process. This paper presents an automated adaptation system for transforming EUD components to a standard format. Method: This system is based on the use of description logic. Based on a generic UML2 data model, this description logic is able to check whether an end-user component can be transformed to this modeling language through subsumption or as an instance of the UML2 model. Besides it automatically finds a consistent, non-ambiguous and finite set of XSLT mappings to automatically prepare data in order to leverage the component as part of a tool that conforms to the target UML2 component model. Results: The proposed system has been successfully applied to components from four prominent EUD tools. These components were automatically converted to a standard format. In order to validate the proposed system, rich internet applications (RIA) used as an operational support system for operators at a large services company were developed using automatically adapted standard format components. These RIAs would be impossible to develop using each EUD tool separately. Conclusion: The positive results of applying our system for automatically adapting components from current tool catalogues are indicative of the system?s effectiveness. Use of this system could foster the growth of web EUD component catalogues, leveraging a vast ecosystem of user-centred SaaS to further current EUSE trends.

Introducción de criterios de sostenibilidad en la elección de emplazamientos industriales mediante modelos multicriterio

(SPA) La elección de localizaciones para la implantación de actividades industriales es un problema complejo, donde a los criterios de coste y eficiencia se han ido añadiendo otros nuevos relativos tanto al impacto en el medio ambiente como a la imagen de la empresa reflejada en la Responsabilidad Social Empresarial. Los criterios medioambientales han ido adquiriendo gran relevancia en la decisión final, hasta convertirse, gracias a la obligación de someter los proyectos a evaluación ambiental, en elementos clave en la decisión final. Por ello, resulta relativamente frecuente que los promotores consulten previamente con la Administración sobre la viabilidad de sus proyectos antes de iniciar un dilatado procedimiento administrativo. En este trabajo se plantea la utilización de indicadores de sostenibilidad y su aplicación, a través de un modelo de decisiones multicriterio, para la ordenación de las distintas opciones de ubicación inicialmente consideradas, de tal forma que se conviertan en instrumento de tanteo y ayuda en la toma de estas decisiones. Para mostrar su utilidad se propone la utilización de la herramienta de apoyo basada en la metodología PROMETHEE y su aplicación en la ordenación de cinco emplazamientos alternativos para la instalación de una cementera en la Comunidad de Madrid según criterios de sostenibilidad. (ENG) The choice of locations for the implementation of industrial activities is a complex problem where the cost and efficiency criteria have been adding new ones relating to the environment impact and the company’s corporate image reflected in Corporate Social Responsability. The environmental criteria have been getting big importance in the final decision, to become key elements in the final decision, due to the duty of submit of environmental assessment projects. Therefore, promoters, quite often, ask previously to the Administration about the viability of their projects before starting a lengthy administrative procedure. This paper proposes the use of sustainability indicators and their application through a multi-criteria decision model for managing the establishment options initially considered, so that they become an help instrument of estimation in order to making these decisions. To show its usefulness we propose the use of the support tool for decision making based on the PROMETHEE methodology and its application in the management of 5 alternative sites for the installation of a cement factory in the Community of Madrid under sustainability criteria.

Herramienta EN 301 549: cliente web

En el año 2014 se publicó, bajo mandato de la Comisión Europea, la Norma Europea EN 301 549, titulada “Requisitos de accesibilidad de productos y servicios TIC aplicables a la contratación pública en Europa”. El objetivo de dicha norma es que los productos o servicios TIC (Tecnologías de la Información y la Comunicación) adquiridos por cualquier administración pública europea puedan ser utilizados por personas con diversas características y capacidades, incluyendo a personas con discapacidad. La norma EN 301 549 es compleja, ya que contiene más de 200 requisitos y recomendaciones, que se aplican o no a un producto o servicio TIC en función de las características de dicho producto o servicio. Por ello se ha planteado, desde el Grupo de Investigación en Tecnología Informática y de las Comunicaciones (CETTICO), el desarrollo de una herramienta de soporte a la evaluación del cumplimiento de la norma. La herramienta permitirá a grupos de trabajo anotar los resultados de la evaluación de accesibilidad de un producto o servicio TIC siguiendo los requisitos de la norma Europea EN 301 549. Este trabajo de Fin de Grado se centra en el diseño y codificación del cliente web de la herramienta. Se parte de los resultados de un TFG y un practicum anteriores. En el TFG realizado por Laura Elorrieta [Elorrieta, 2014], se diseñó la interacción del sistema y se evaluó su grado de usabilidad. En el practicum [Montero, 2015], posterior al TFG de Laura Elorrieta, se eligieron las tecnologías web que se iban a utilizar y se realizó el diseño y la implementación mediante prototipos iterativos de la gestión de proyectos de evaluación. El trabajo que se ha realizado en el TFG ha consistido en el diseño de la interfaz de usuario analizando los cambios a realizar en el diseño, debido a los errores de usabilidad conocidos, y la implementación del prototipo funcional de la herramienta. Junto con la parte servidor del TFG de mi compañero Rubén Ortiz Burgos y la interfaz de usuario de este TFG se ha obtenido una aplicación web para realizar evaluaciones de accesibilidad de productos o servicios TIC siguiendo los requisitos de la norma EN 301 549. El prototipo funcional contiene diez páginas web que recogen las diferentes acciones y tareas que pueden realizar los usuarios en función del rol que desempeñen. EL diseño y la implementación se han llevado a cabo empleando las tecnologías web HTML5, CSS3, JavaScript, jQuery y las librerías de Foundation frontend framework.---ABSTRACT---In 2014, under the European Commission mandate, the European standard EN 301 549 has been published under the title “Accessibility requirements applicable to ICT products and procurement services in Europe”. The goal of this standard is that the products or services ICT (Information Communication Technology) acquires by every European public administration can be used by every person with different characteristics and capacities, including those with disability. The rule EN 301549 is very complex, since it has more than 200 requirements and recommendations that can be or not applied to an ICT product or service based on its characteristics of the given product or service. That’s why a development of a support tool has been proposed to the rating of the compliance of the rule, by the Research Group of Informatics Technology and Communication. This tool will allow working groups to record the results of the compliance of accessibility of a product or service following the requirements of the European Standard EN 301549. This Final Degree Work focuses in the design and the coding of the web customer of this tool. The results of a TFG and previous practicums have been used for this. The TFG performed by Laura Elorrieta [Elorrieta, 2014], the interaction of the system was designed and degree of usability was evaluated. In the practicum [Montero, 2015], after the TFG Laura Elorrieta, web technologies used were chosen and the design and implementation were performed using iterative prototyping project management evaluation. The work done on the TFG was to design the users interface to perform analyzing changes in design due to errors known usability and working prototype implementation of the tool. Together with the server part of the TFG my partner Rubén Ortiz Burgos and the user interface done of this TFG it has obtained a web application for the conduct of evaluations accessibility of products or services ICT following the requirements of the EN 301 549. The functional prototype contains ten web sites that collect the various activities and tasks that users can perform based on the role they perform. The design and implementation have been carried out using the technologies web HTML5, CSS3, Java Script, jQuery and the libraries of Foundation fronted framework.

A semantic framework for textual data enrichment

In this work we present a semantic framework suitable of being used as support tool for recommender systems. Our purpose is to use the semantic information provided by a set of integrated resources to enrich texts by conducting different NLP tasks: WSD, domain classification, semantic similarities and sentiment analysis. After obtaining the textual semantic enrichment we would be able to recommend similar content or even to rate texts according to different dimensions. First of all, we describe the main characteristics of the semantic integrated resources with an exhaustive evaluation. Next, we demonstrate the usefulness of our resource in different NLP tasks and campaigns. Moreover, we present a combination of different NLP approaches that provide enough knowledge for being used as support tool for recommender systems. Finally, we illustrate a case of study with information related to movies and TV series to demonstrate that our framework works properly.

The role of software tools in influencing creative problem solving in engineering design and education

Creativity is increasingly recognised as an essential component of engineering design. This paper describes an exploratory study into the nature and importance of creativity in engineering design problem solving in relation to the possible impact of software design tools. The first stage of the study involved an empirical investigation in the form of a case study of the use of standard CAD tool sets and the development of a systems engineering software support tool. It was found that there were several ways in which CAD influenced the creative process, including enhancing visualisation and communication, premature fixation, circumscribed thinking and bounded ideation. The tool development experience uncovered the difficulty in supporting creative processes from the developer's perspective. The issues were the necessity of making assumptions, achieving a balance between structure and flexibility, and the pitfalls of satisfying user wants and needs. The second part of the study involved the development of a model of the creative problem solving process in engineering design. This provided a possible explanation for why purpose designed engineering software tools might encourage an analytical problem solving approach and discourage a more creative approach.

Indagine modellistica sulla tenuta idraulica delle difese arginali deputate alla protezione idraulica del territorio

La prima parte di questo lavoro di tesi tratta dell’interazione tra un bacino di laminazione e il sottostante acquifero: è in fase di progetto, infatti, la costruzione di una cassa di espansione sul torrente Baganza, a monte della città di Parma. L’obiettivo di tale intervento è di ridurre il rischio di esondazione immagazzinando temporaneamente, in un serbatoio artificiale, la parte più pericolosa del volume di piena che verrebbe rilasciata successivamente con portate che possono essere agevolmente contenute nel tratto cittadino del torrente. L’acquifero è stato preliminarmente indagato e monitorato permettendone la caratterizzazione litostratigrafica. La stratigrafia si può riassumere in una sequenza di strati ghiaioso-sabbiosi con successione di lenti d’argilla più o meno spesse e continue, distinguendo due acquiferi differenti (uno freatico ed uno confinato). Nel presente studio si fa riferimento al solo acquifero superficiale che è stato modellato numericamente, alle differenze finite, per mezzo del software MODFLOW_2005. L'obiettivo del presente lavoro è di rappresentare il sistema acquifero nelle condizioni attuali (in assenza di alcuna opera) e di progetto. La calibrazione è stata condotta in condizioni stazionarie utilizzando i livelli piezometrici raccolti nei punti d’osservazione durante la primavera del 2013. I valori di conducibilità idraulica sono stati stimati per mezzo di un approccio geostatistico Bayesiano. Il codice utilizzato per la stima è il bgaPEST, un software gratuito per la soluzione di problemi inversi fortemente parametrizzati, sviluppato sulla base dei protocolli del software PEST. La metodologia inversa stima il campo di conducibilità idraulica combinando osservazioni sullo stato del sistema (livelli piezometrici nel caso in esame) e informazioni a-priori sulla struttura dei parametri incogniti. La procedura inversa richiede il calcolo della sensitività di ciascuna osservazione a ciascuno dei parametri stimati; questa è stata valutata in maniera efficiente facendo ricorso ad una formulazione agli stati aggiunti del codice in avanti MODFLOW_2005_Adjoint. I risultati della metodologia sono coerenti con la natura alluvionale dell'acquifero indagato e con le informazioni raccolte nei punti di osservazione. Il modello calibrato può quindi essere utilizzato come supporto alla progettazione e gestione dell’opera di laminazione. La seconda parte di questa tesi tratta l'analisi delle sollecitazioni indotte dai percorsi di flusso preferenziali causati da fenomeni di piping all’interno dei rilevati arginali. Tali percorsi preferenziali possono essere dovuti alla presenza di gallerie scavate da animali selvatici. Questo studio è stato ispirato dal crollo del rilevato arginale del Fiume Secchia (Modena), che si è verificato in gennaio 2014 a seguito di un evento alluvionale, durante il quale il livello dell'acqua non ha mai raggiunto la sommità arginale. La commissione scientifica, la cui relazione finale fornisce i dati utilizzati per questo studio, ha attribuito, con molta probabilità, il crollo del rilevato alla presenza di tane di animali. Con lo scopo di analizzare il comportamento del rilevato in condizioni integre e in condizioni modificate dall'esistenza di un tunnel che attraversa il manufatto arginale, è stato realizzato un modello numerico 3D dell’argine mediante i noti software Femwater e Feflow. I modelli descrivono le infiltrazioni all'interno del rilevato considerando il terreno in entrambe le porzioni sature ed insature, adottando la tecnica agli elementi finiti. La tana è stata rappresentata da elementi con elevata permeabilità e porosità, i cui valori sono stati modificati al fine di valutare le diverse influenze sui flussi e sui contenuti idrici. Per valutare se le situazioni analizzate presentino o meno il verificarsi del fenomeno di erosione, sono stati calcolati i valori del fattore di sicurezza. Questo è stato valutato in differenti modi, tra cui quello recentemente proposto da Richards e Reddy (2014), che si riferisce al criterio di energia cinetica critica. In ultima analisi è stato utilizzato il modello di Bonelli (2007) per calcolare il tempo di erosione ed il tempo rimanente al collasso del rilevato.

Detecting and monitoring the symptoms of Parkinson's disease using smartphones:a pilot study

Background: Remote, non-invasive and objective tests that can be used to support expert diagnosis for Parkinson's disease (PD) are lacking. Methods: Participants underwent baseline in-clinic assessments, including the Unified Parkinson's Disease Rating Scale (UPDRS), and were provided smartphones with an Android operating system that contained a smartphone application that assessed voice, posture, gait, finger tapping, and response time. Participants then took the smart phones home to perform the five tasks four times a day for a month. Once a week participants had a remote (telemedicine) visit with a Parkinson disease specialist in which a modified (excluding assessments of rigidity and balance) UPDRS performed. Using statistical analyses of the five tasks recorded using the smartphone from 10 individuals with PD and 10 controls, we sought to: (1) discriminate whether the participant had PD and (2) predict the modified motor portion of the UPDRS. Results: Twenty participants performed an average of 2.7 tests per day (68.9% adherence) for the study duration (average of 34.4 days) in a home and community setting. The analyses of the five tasks differed between those with Parkinson disease and those without. In discriminating participants with PD from controls, the mean sensitivity was 96.2% (SD 2%) and mean specificity was 96.9% (SD 1.9%). The mean error in predicting the modified motor component of the UPDRS (range 11-34) was 1.26 UPDRS points (SD 0.16). Conclusion: Measuring PD symptoms via a smartphone is feasible and has potential value as a diagnostic support tool.

Time, Cost, and Environmental Impact Analysis for Sustainable Design at Multiple Building Levels

Construction projects are complex endeavors that require the involvement of different professional disciplines in order to meet various project objectives that are often conflicting. The level of complexity and the multi-objective nature of construction projects lend themselves to collaborative design and construction such as integrated project delivery (IPD), in which relevant disciplines work together during project conception, design and construction. Traditionally, the main objectives of construction projects have been to build in the least amount of time with the lowest cost possible, thus the inherent and well-established relationship between cost and time has been the focus of many studies. The importance of being able to effectively model relationships among multiple objectives in building construction has been emphasized in a wide range of research. In general, the trade-off relationship between time and cost is well understood and there is ample research on the subject. However, despite sustainable building designs, relationships between time and environmental impact, as well as cost and environmental impact, have not been fully investigated. The objectives of this research were mainly to analyze and identify relationships of time, cost, and environmental impact, in terms of CO2 emissions, at different levels of a building: material level, component level, and building level, at the pre-use phase, including manufacturing and construction, and the relationships of life cycle cost and life cycle CO2 emissions at the usage phase. Additionally, this research aimed to develop a robust simulation-based multi-objective decision-support tool, called SimulEICon, which took construction data uncertainty into account, and was capable of incorporating life cycle assessment information to the decision-making process. The findings of this research supported the trade-off relationship between time and cost at different building levels. Moreover, the time and CO2 emissions relationship presented trade-off behavior at the pre-use phase. The results of the relationship between cost and CO2 emissions were interestingly proportional at the pre-use phase. The same pattern continually presented after the construction to the usage phase. Understanding the relationships between those objectives is a key in successfully planning and designing environmentally sustainable construction projects.

A atenção à crise e o apoio matricial: analisadores da estratégia atenção psicossocial

The National Policy on Mental Health is characterized as a territorial - political community , and it has the Psychoso cial Care Strategy (Eaps) as guideline for the proposal and the development of their actions. In its design, CAPS is idealized to be a strategic equipment within the Psychoso cial Care Network/RAPS. Matricial support and at tention to the crisis constitute strategic areas of action of CAPS in its replacement mission , and as it is g uided by the scope of deinstitutionalization, those are essential to the success of these services. We argue that sustain crises in existential territories of life is a condition for the effectiveness of psychosocial care and, ultimately, to the sustainability of its Reform. In this direction, the matricial support tool reveals a territorial supporter, intercessory and powerful in building a psychosocial care to the crisis. Recognized as one of the major challenges by the Brazilian Ministry of Health, forward these fronts materializes for workers in their mi cropolitical crafts. Our research arises as an investment toward empower them , and aimed to understand the operationalization of attention to the crisis and matricial support in a CAPS II, in the view of its workers . Besides, it aims to examine such practi ces forward the principles and purposes of Psychosocial Care Strategy. Inspired by the research - intervention and by the political and social ideas of Institutiona l Analysis, we offer a space for reflection and exchange, by implicational interviews , enablin g workers to launch them in analysis of practices in the EAPs view. We have done a documentary consulting CAPS Technical Project, and a return stage to the institution, by organizing workshop and conversation groups with CAPS workers. The results have show n that there are institutional logics in competition on that service. When operating the logic risk, some difficulties in sustaining most intense crisis situations were identified, the psychiatric hospital internment is used as a facility, particularly in view of some cases, in which the aggressiveness of the person in crises becomes aggressive, and when the brackets SAMU, the CAPS III and Comprehensive Care Beds do not respond satisfactorily to their users requests. Order weaknesses were indicated in this thesis as macropolitical and micropolitical interfering in network support. The matricial actions were identified as a powerful intercessor resource in crisis care appeared weakened, and indicates little porosity in the relationship between the Service and the territory where it takes place. Noticed by the logic of home care, without operate primarily as a knowledge exchange device, we saw capture points in the logic of assistance with ambulatoriza tion production of CAPS, welfare practices and "ext empore " . T he E APs , although it emerge s as a guiding, it is not seen to workers as effective practice. On the one hand, the results signaled that the attention to the crisis and the matricial actions are developed without tenacious connection with the purposes of EA Ps, on the other hand, successful cases were indicated with the main leads to conducting wire of intersectoral actions to the powerful bonds and to the participation of user in their care process es , indicating insurgent forces tha t intend by traditional lo gic .

Anticipating future risk in social-ecological systems using fuzzy cognitive mapping: the case of wildfire in the Chiquitania, Bolivia

Understanding complex social-ecological systems, and anticipating how they may respond to rapid change, requires an approach that incorporates environmental, social, economic, and policy factors, usually in a context of fragmented data availability. We employed fuzzy cognitive mapping (FCM) to integrate these factors in the assessment of future wildfire risk in the Chiquitania region, Bolivia. In this region, dealing with wildfires is becoming increasingly challenging because of reinforcing feedbacks between multiple drivers. We conducted semistructured interviews and constructed different FCMs in focus groups to understand the regional dynamics of wildfire from diverse perspectives. We used FCM modelling to evaluate possible adaptation scenarios in the context of future drier climatic conditions. Scenarios also considered possible failure to respond in time to the emergent risk. This approach proved of great potential to support decision making for risk management. It helped identify key forcing variables and generate insights into potential risks and trade-offs of different strategies. The “Hands-off” scenario resulted in amplified impacts driven by intensifying trends, affecting particularly the agricultural production under drought conditions. The “Fire management” scenario, which adopted a bottom-up approach to improve controlled burning, showed less trade-offs between wildfire risk reduction and production compared with the “Fire suppression” scenario. Findings highlighted the importance of considering strategies that involve all actors who use fire, and the need to nest these strategies for a more systemic approach to manage wildfire risk. The FCM model could be used as a decision-support tool and serve as a “boundary object” to facilitate collaboration and integration of different perceptions of fire in the region. This approach also has the potential to inform decisions in other dynamic frontier landscapes around the world that are facing increased risk of large wildfires.

O Processo de Planejamento Estratégico em Pequenas Empresas

O planejamento estratégico é o processo através do qual as empresas identificam recursos potenciais, reconhecem fraquezas, avaliam oportunidades e ameaças no ambiente que atuam e formulam as estratégias para obter vantagens competitivas sobre a concorrência, assegurando o sucesso dos resultados planejados. Esse trabalho desenvolveu-se com o objetivo de aprofundar os conhecimentos sobre o processo de planejamento estratégico e adaptá-lo à realidade das empresas de pequeno porte, através de um caso prático, com a elaboração do plano de negócios de uma pequena empresa de prestação de serviços no segmento de educação especial, o caso “Mundo Novo Educação Especial”. Com relação à metodologia adotada, podemos descrevê-la como uma abordagem qualitativa, com design exploratório através de pesquisa bibliográfica para a fundamentação teórica sobre o processo de planejamento estratégico, seguida de estudo de caso aplicado ao planejamento estratégico da empresa Mundo Novo Educação Especial, com levantamento de dados secundários internos e externos, e dados primários qualitativos. Dentre as conclusões do estudo foi possível identificar a existência de uma grande lacuna de conhecimento sobre os processos de gestão empresarial no ambiente da empresa pesquisada, e que esse despreparo e a falta de planejamento podem torna-la mais vulnerável aos riscos do mercado e contribuir para o seu insucesso. Isso reforça a importância do processo de planejamento estratégico como uma ferramenta de apoio que amplia o conhecimento sobre o ambiente de negócios, desenvolve habilidades de gestão e que pode ser adequado a todos os tipos de empresas, inclusive às empresas de pequeno porte, como no caso estudado.

Sistema de predição de alarmes em processos industriais por classificação não-supervisionada

Um sistema de predição de alarmes com a finalidade de auxiliar a implantação de uma política de manutenção preditiva industrial e de constituir-se em uma ferramenta gerencial de apoio à tomada de decisão é proposto neste trabalho. O sistema adquire leituras de diversos sensores instalados na planta, extrai suas características e avalia a saúde do equipamento. O diagnóstico e prognóstico implica a classificação das condições de operação da planta. Técnicas de árvores de regressão e classificação não-supervisionada são utilizadas neste artigo. Uma amostra das medições de 73 variáveis feitas por sensores instalados em uma usina hidrelétrica foi utilizada para testar e validar a proposta. As medições foram amostradas em um período de 15 meses.
