- Training control centers' operators in incident diagnosis and power restoration using intelligent tutoring systemsPublication . Faria, Luiz; Silva, A.; Vale, Zita; Marques, A.The activity of Control Center operators is important to guarantee the effective performance of Power Systems. Operators’ actions are crucial to deal with incidents, especially severe faults like blackouts. In this paper, we present an Intelligent Tutoring approach for training Portuguese Control Center operators in tasks like incident analysis and diagnosis, and service restoration of Power Systems. Intelligent Tutoring System (ITS) approach is used in the training of the operators, having into account context awareness and the unobtrusive integration in the working environment. Several Artificial Intelligence techniques were criteriously used and combined together to obtain an effective Intelligent Tutoring environment, namely Multiagent Systems, Neural Networks, Constraint-based Modeling, Intelligent Planning, Knowledge Representation, Expert Systems, User Modeling, and Intelligent User Interfaces.
- A web-based intelligent tutoring system on teaching and learning electrical projectPublication . Gomes, António Augusto Araújo; Miranda, Rui; Vale, Zita; Faria, LuizThe Information and Communication Technology (ICT) provide new strategies for disseminating information and new communication models in order to change attitudes and human behaviour concerning to education. Nowadays the internet is crucial as a means of communication and information sharing. To education or tutorship will be required to use ICT, supported on the internet, to establish the communication of teacher-student and student-student, disseminating the content of the subjects, and as a way of teaching and learning process. This paper presents an intelligent tutor that aims to be a tool to support teaching and learning in the field of the electrical engineering project.
- Using an ambient intelligent architecture for developing an intelligent tutoring system for training operators of power system control centresPublication . Faria, Luiz; Silva, António S.; Ramos, Carlos; Gomes, Luis; Vale, Zita; Marques, A.This paper describes an architecture conceived to integrate Power Sys-tems tools in a Power System Control Centre, based on an Ambient Intelligent (AmI) paradigm. This architecture is an instantiation of the generic architecture proposed in [1] for developing systems that interact with AmI environments. This architecture has been proposed as a consequence of a methodology for the inclu-sion of Artificial Intelligence in AmI environments (ISyRAmI - Intelligent Sys-tems Research for Ambient Intelligence). The architecture presented in the paper will be able to integrate two applications in the control room of a power system transmission network. The first is SPARSE expert system, used to get diagnosis of incidents and to support power restoration. The second application is an Intelligent Tutoring System (ITS) incorporating two training tools. The first tutoring tool is used to train operators to get the diagnosis of incidents. The second one is another tutoring tool used to train operators to perform restoration procedures.
- PCMAT, an adaptive learning platformPublication . Couto, Paulo; Fernandes, Marta; Martins, Constantino; Faria, LuizThis paper is about PCMAT, an adaptive learning platform for Mathematics in Basic Education schools. Based on a constructivist approach, PCMAT aims at verifying how techniques from adaptive hypermedia systems can improve e-learning based systems. To achieve this goal, PCMAT includes a Pedagogical Model that contains a set of adaptation rules that influence the student-platform interaction. PCMAT was subject to a preliminary testing with students aged between 12 and 14 years old on the subject of direct proportionality. The results from this preliminary test are quite promising as they seem to demonstrate the validity of our proposal.
- Uso das tecnologias de informação e comunicação no ensino – portal de ensino aprendizagem do projecto electrotécnicoPublication . Gomes, António Augusto Araújo; Vale, Zita; Faria, Luiz; Ramos, SérgioAs Tecnologias da Informação e Comunicação (TIC) permitem novas estratégias de difusão da informação e novos modelos de comunicação, com a proposta de modificar as atitudes e o comportamento humano em relação à Educação. Actualmente a internet é fundamental como meio de comunicação e partilha de informação. Ao ensino será exigido a utilização de TIC, suportadas na internet, para estabelecer a comunicação professor-aluno e aluno-aluno, para divulgação de conteúdos das unidades curriculares, e mesmo como meio de ensino/aprendizagem. O Portal de Ensino e Aprendizagem do Projecto Electrotécnico (PEAPE) pretende ser uma ferramenta de apoio ao ensino/aprendizagem, de unidades curriculares no Âmbito do projecto electrotécnico.
- Learning objects recommendation in an adaptive educational hypermedia systemPublication . Fernandes, Marta; Couto, Paulo; Martins, Constantino; Faria, Luiz; Bastos, Cristina; Costa, FátimaThe aim of this paper is presenting the modules of the Adaptive Educational Hypermedia System PCMAT, responsible for the recommendation of learning objects. PCMAT is an online collaborative learning platform with a constructivist approach, which assesses the user’s knowledge and presents contents and activities adapted to the characteristics and learning style of students of mathematics in basic schools. The recommendation module and search and retrieval module choose the most adequate learning object, based on the user's characteristics and performance, and in this way contribute to the system’s adaptability.

- Cyber-physical intelligence in the context of power systemsPublication . Ramos, Carlos; Vale, Zita; Faria, LuizCyber-Physical Intelligence is a new concept integrating Cyber-Physical Systems and Intelligent Systems. The paradigm is centered in incorporating intelligent behavior in cyber-physical systems, until now too oriented to the operational technological aspects. In this paper we will describe the use of Cyber-Physical Intelligence in the context of Power Systems, namely in the use of Intelligent SCADA (Supervisory Control and Data Acquisition) systems at different levels of the Power System, from the Power Generation, Transmission, and Distribution Control Centers till the customers houses.
- Information and communication technologies in education – a web-based intelligent tutoring system on teaching and learning electrical projectPublication . Gomes, António Augusto Araújo; Vale, Zita; Faria, LuizElectrical activity is extremely broad and distinct, requiring by one hand, a deep knowledge on rules, regulations, materials, equipments, technical solutions and technologies and assistance in several areas, as electrical equipment, telecommunications, security and efficiency and rational use of energy, on the other hand, also requires other skills, depending on the specific projects to be implemented, being this knowledge a characteristic that belongs to the professionals with relevant experience, in terms of complexity and specific projects that were made.
- Adaptation model for PCMAT – Mathematics collaborative learning platformPublication . Fernandes, Marta; Martins, Constantino; Faria, Luiz; Couto, Paulo; Valente, Cristiano; Bastos, Cristina; Costa, Fátima; Carrapatoso, EuricoThe aim of this paper is to present an adaptation model for an Adaptive Educational Hypermedia System, PCMAT. The adaptation of the application is based on progressive self-assessment (exercises, tasks, and so on) and applies the constructivist learning theory and the learning styles theory. Our objective is the creation of a better, more adequate adaptation model that takes into account the complexities of different users.
