    "Utilização de padrões de desenho de software no desenvolvimento de Sistemas de Informação Geográfica" - O caso da Região Demarcada do Douro
    ( 2011) Nelson Bilber Rodrigues ; Lino Oliveira ; Lígia Silva ; António Coelho ; 4290 ; 4777 ; 3574 ; 3132
    A Região Demarcada do Douro (RDD) possui características únicas a nível mundial e requer um sistema de classificação das parcelas com vinha que assegure os níveis de elevada qualidade dos vinhos do Douro e Porto. Com base neste pressuposto, foi desenvolvido um Sistema de Informação Geográfica para a gestão e classificação das parcelas com vinha da RDD. O sistema foi desenhado utilizando padrões de desenho de software com o objectivo de tornar a sua evolução sustentável, respondendo aos novos requisitos e preservando o legado inicial. Neste artigo é apresentada uma metodologia que permite a utilização de Rich Internet Application (RIA) sobre as aplicações Web tradicionais, proporcionando interfaces gráficas (GUI) mais ricas, dinâmicas e interactivas, tornando as aplicações mais atractivas para o utilizador. É apresentado ainda um padrão de desenho de software, derivado do Model -View- Controller (MVC) designado por Model - View - LogicGateway (MVLG). É um padrão de arquitectura de softw

    A testing and certification methodology for an Ambient-Assisted Living ecosystem
    ( 2013) João Pascoal Faria ; Bruno Carvalhido Lima ; Tiago Boldt Sousa ; Ângelo Martins
    To cope with the needs raised by the demographic changes in our society, several Ambient-Assisted Living (AAL) technologies have emerged in recent years, but those 'first offers' are often monolithic, incompatible and thus expensive and potentially not sustainable. The AAL4ALL project aims at improving that situation through the development of an open ecosystem of interoperable products and services for AAL, tied together via an integration infrastructure. To that end, the project encompasses the specification of a set of reference models and requirements for interoperable products and services, against which candidate products and services can be tested and certified, and subsequently integrated as components of the ecosystem. This paper proposes a testing and certification methodology for such an ecosystem. © 2013 IEEE.

    Automatic Street Surface Modeling for Web-Based Urban Information Systems
    ( 2013) Dolores Robles Ortega,MD ; Ortega,L ; António Coelho ; Feito,F ; Augusto Sousa
    The growing demand for virtual urban models in emerging areas of interest has promoted a variety of techniques for automating the creation of virtual scenes with a high level of realism. However, visualization is not always the only aim in many applications. Increasingly, urban systems are also required for management, analysis, or interaction with very different types of information. Three-dimensional (3D) urban entities should maintain neighbor relations, and being inserted in a geospatial database in order to enable associative queries, one of the most important features associated with 3D urban geographic information system (GIS). Additional challenges are found when these three-dimensional models are implemented in web-based systems. This paper proposes a method for automatic modeling of buildings and street surfaces of entire real cities by combining computer graphics, computational geometry, and GIS techniques. The sources of information employed are two-dimensional (2D) GIS and its associated digital elevation models (DEMs) in order to provide real terrain features. The virtual environment supports web-based navigation and data interaction. The case study was performed in Jaen, Spain, a hilly city with more than 1,000 blocks of buildings. The 3D city model was generated using the public data provided by the general cadastral office of Jaen and the DEM information of this area. The topological relations between the geometric urban entities were inserted in the spatial database and the graphics and thematic information could be accessed through the Internet. All these features are highly desirable for decision making in urban planning. DOI: 10.1061/(ASCE)UP.1943-5444.0000131. (C) 2013 American Society of Civil Engineers.

    Teaching of Fourier Series Expansions in undergraduate education
    ( 2013) Reis,MJCS ; Soares,S ; Cardeal,S ; Raul Morais ; Emanuel Peres Correia ; Ferreira,PJSG
    Here we discuss the teaching of Fourier series concepts in connection with undergraduate Electrical Engineering education. We briefly review some of the basic Fourier series theory, and present an Android application that has been found useful in this context. As expected, the application has an easy-to-use, friendly interface, and can be viewed as a tool to help undergraduate students test and assess the Fourier series expansions on a typical set of signals, whose analytical Fourier series coefficients were found during the theoretical lectures. Additionally, students can also control the total approximation error and the number of terms/harmonics used in the expansion. It seems that our students prefer this Android application to the traditional applet fashioned web-based applications.

    Real-time Augmented Reality shopping platform for studying consumer cognitive experiences
    ( 2013) Stoyanova,J ; Goncalves,R ; António Coelho ; Pedro Brito
    Augmented Reality (AR) is a technology which produces a synthesis between a computer-generated data and the physical world of a viewer while establishing 3D registration and real time interaction. Among the wide range of application of AR, its use in advertising shopping experiences has recently been embraced by advertisers due to its novelty and engaging potential. Part of a wider research aiming at understanding the impact of AR on consumer psychology, this paper presents a demo platform application developed for a real-time shopping experience for shoes and attempts to define a ground base for posterior marketing research in the field. In order to fully evaluate consumer experiences and compare with the main AR platform two other shopping applications were designed: a marker-based and a static one. The platform will assist in exploring the antecedents of consumer purchase intention and in defining metrics for measuring shopping experiences with AR.

    Semi-automatic Virtual Reconstruction of Ancient Roman Houses
    ( 2013) Telmo Oliveira Adão ; Luís Gonzaga Magalhães ; Emanuel Peres Correia
    Video Games may be used with different applications in mind, for entertainment, training and simulation or even as teaching tools. However, the production of contents for such games, namely game scenarios with virtual worlds composed by cities and related elements (streets, buildings, furniture and so on) may require a laborious effort by multidisciplinary teams which lead to an expensive and time consuming solution. In order to avoid the development burden, procedural modeling techniques have been created and applied to generate virtual models of buildings and cities expeditiously with high degree of detail and realism. Nevertheless, most of the existing techniques use complex sets of rules to produce models without being aware of the architectonic structures and its relationships. Thereby, in order to simplify the generation process and rule dealing we propose, in this paper, an ontology-based procedural modeling methodology which integrates an ontological structure, describing city elements and the relationships between each other, and a combined set of procedural techniques to generate roman houses. The preliminary results point to a method capable of producing roman houses expeditiously, including the interiors and the exteriors.

    Identifying different visual patterns in web users behaviour
    ( 2013) Goncalves,M ; Tânia Vilela Rocha ; Luís Gonzaga Magalhães ; Emanuel Peres Correia ; Maximino Bessa ; Chalmers,A
    On the internet one can find all kinds of information and perform a multitude of tasks such as searching for information about any subject, purchase goods and services, or enquiring about a particular company. When navigating the web, our focus (where we look) can be captured involuntary through a visual stimulus, or may be directed in a controlled manner depending on the task that we are performing. The layouts of web sites range from simple to highly complex. When creating new layouts, knowing what information is most important when a user is performing a task and which areas are supposed to attract his/her attention are important issues in order to make a web site easier to interpret and consequently their usability. In this paper we present an eye tracking study of users' visual behaviour when surfing on websites and investigate if it is possible to determine likely visual patterns. We show that the visual patterns are different depending on the task that is being performed and not on the web site where it is being carried out. © 2011 ACM.

    The Dotted-Board Model: A new MIP model for nesting irregular shapes
    ( 2013) Toledo,FMB ; Maria Antónia Carravilla ; Cristina Ribeiro ; José Fernando Oliveira ; António Miguel Gomes
    The nesting problem, also known as irregular packing problem, belongs to the generic class of cutting and packing (C&P) problems. It differs from other 2-D C&P problems in the irregular shape of the pieces. This paper proposes a new mixed-integer model in which binary decision variables are associated with each discrete point of the board (a dot) and with each piece type. It is much more flexible than previously proposed formulations and solves to optimality larger instances of the nesting problem, at the cost of having its precision dependent on board discretization. To date no results have been published concerning optimal solutions for nesting problems with more than 7 pieces. We ran computational experiments on 45 problem instances with the new model, solving to optimality 34 instances with a total number of pieces ranging from 16 to 56, depending on the number of piece types, grid resolution and the size of the board. A strong advantage of the model is its insensitivity to piece and board geometry, making it easy to extend to more complex problems such as non-convex boards, possibly with defects. Additionally, the number of binary variables does not depend on the total number of pieces but on the number of piece types, making the model particularly suitable for problems with few piece types. The discrete nature of the model requires a trade-off between grid resolution and problem size, as the number of binary variables grows with the square of the selected grid resolution and with board size.

    GIS2R-Augmented Reality and 360 degrees Panoramas Framework for Geomarketing
    ( 2013) Leonel João Dias ; António Coelho ; Rodrigues,A ; Rebelo,C ; Cardoso,A
    Recent developments in the areas of augmented reality, 360 degrees panoramas, social networks and geographical information systems enable the development of new solutions, which can contribute to several areas. This paper presents a new, Unity3D [8] based framework for the development of immersive augmented reality solutions and 360 degrees panoramas. This solution allows the aggregation of spatial information from disparate and heterogeneous sources, comprising the visualization of points of interest (POIs), image overlays (photographs), 3D objects and navigation between panoramas. This framework also features a strong multiplatform (web and mobile) component, and the possibility of developing new functional modules that can be easily plugged in. A prototype based on this solution, for geomarketing, is also presented.

    Digital Services in Immersive Urban Virtual Environments
    ( 2013) Meira,C ; Freitas,J ; Luis Barbosa ; Miguel Correia Melo ; Maximino Bessa ; Luís Gonzaga Magalhães
    Virtual Environments (VE) systems may provide a new way to deliver information and services in many areas, for example in tourism, urban planning and education. In urban VE there is a close link between the virtual environment and the urban environment that are intended to represent. These VE can be an intuitive way to access a set of services with a direct association to the real object or entity to which they are related. In this article, we describe a case study that aimed at exploring the possibility of using new interfaces to exploit and use services in urban VE with a greater sense of immersiveness. The results indicate that the VE interfaces are a natural and intuitive access to digital services. While users have felt a greater difficulty in performing some of the tasks in immersive scenario, the majority considered that this scenario provided a greater sense of immersion and realism.

    A framework for wireless sensor networks management for precision viticulture and agriculture based on IEEE 1451 standard
    ( 2013) Fernandes,MA ; Matos,SG ; Emanuel Peres Correia ; Carlos Rompante Cunha ; Lopez,JA ; Ferreira,PJSG ; Reis,MJCS ; Raul Morais
    Precision viticulture (PV) and precision agriculture (PA) requires the acquisition and processing of a vast collection of data coming typically from large scale and heterogeneous sensor networks. Unfortunately, sensor integration is far from being simple due to the number of incompatible network specifications and platforms. The adoption of a common, standard communication interface would allow the engineer to abstract the relation between the sensor and the network. This would reduce the development efforts and emerge as an important step towards the adoption of "plug-and-play" technology in PA/PV sensor networks. This paper explores this need and introduces a framework for smart data acquisition in PA/PV that relies on the IEEE 1451 family of standards, which addresses the transducer-to-network interoperability issues. The framework includes a ZigBee end device (sMPWiNodeZ),,as an IEEE 1451 WTIM (Wireless Transducer Interface Module), and an IEEE 1451 NCAP (Network Capable Application Processor) that acts as gateway to an information service provider and WSN (Wireless Sensor Network) coordinator. The paper discusses the proposed IEEE 1451 system architecture and its benefits in PA/PV and closes with results/lessons learned from in-field trials towards smarter WSN.
