    Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do grau de Mestre em Engenharia Electrotécnica e ComputadoresThis thesis addresses and contextualizes the problem of diagnostic of an Evolvable Production System (EPS). An EPS is a complex and lively entity composed of intelligent modules that interact through bio-inspired mechanisms, to ensure high system availability and seamless reconfiguration. The actual economic situation together with the increasing demand of high quality and low priced customized products imposed a shift in the production policies of enterprises. Shop floors have to become more agile and flexible to accommodate the new production paradigms. Rather than selling products enterprises are establishing a trend of offering services to explore business opportunities. The new production paradigms, potentiated by the advances in Information Technologies (IT), especially in web related standards and technologies as well as the progressive acceptance of the multi-agent systems (MAS) concept and related technologies, envision collections of modules whose individual and collective function adapts and evolves ensuring the fitness and adequacy of the shop floor in tackling profitable but volatile business opportunities. Despite the richness of the interactions and the effort set in modelling them, their potential to favour fault propagation and interference, in these complex environments, has been ignored from a diagnostic point of view. With the increase of distributed and autonomous components that interact in the execution of processes current diagnostic approaches will soon be insufficient. While current system dynamics are complex and to a certain extent unpredictable the adoption of the next generation of approaches and technologies comes at the cost of a yet increased complexity.Whereas most of the research in such distributed industrial systems is focused in the study and establishment of control structures, the problem of diagnosis has been left relatively unattended. There are however significant open challenges in the diagnosis of such modular systems including: understanding fault propagation and ensuring scalability and co-evolution. This work provides an implementation of a state-of-the-art agent-based interaction-oriented architecture compliant with the EPS paradigm that supports the introduction of a new developed diagnostic algorithm that has the ability to cope with the modern manufacturing paradigm challenges and to provide diagnostic analysis that explores the network dimension of multi-agent systems

    We describe a novel approach to physical oceanography by coordinating remote sensing, multiple autonomous vehicles and ship borne sensors. In contrast with conventional oceanography where ships are the single point of sampling in the middle of a big ocean or are used simply as the base of operations from where autonomous vehicles are deployed, we propose a new approach where ship and autonomous vehicles are coordinated together via satellite communications. We conclude with results and lessons learned from a real-world deployment of the R/V Falkor oceanographic ship together with multiple autonomous vehicles to study the Pacific's Subtropical Front, 800 miles off the coast of San Diego

    Get PDF
    We describe the Ripples cloud-based software for coordination and control of multiple remote assets. Ripples can ingest and disseminate data coming from multiple sources such as physical models, drifting sensors, marine traffic (AIS) and unmanned vehicles deployed in remote areas. On top of data dissemination and awareness, Ripples can also be used for planning the autonomous assets using satellite communications, maintaining the operators in the loop.Peer Reviewe

    Patellid Limpets: An Overview of the Biology and Conservation of Keystone Species of the Rocky Shores

    Get PDF
    This work reviews a broad spectrum of subjects associated to Patellid limpets’ biology such as growth, reproduction, and recruitment, also the consequences of commercial exploitation on the stocks and the effects of marine protected areas (MPAs) in the biology and populational dynamics of these intertidal grazers. Knowledge of limpets’ biological traits plays an important role in providing proper background for their effective management. This chapter focuses on determining the effect of biotic and abiotic factors that influence these biological characteristics and associated geographical patterns. Human exploitation of limpets is one of the main causes of disturbance in the intertidal ecosystem and has occurred since prehistorical times resulting in direct and indirect alterations in the abundance and size structure of the target populations. The implementation of MPAs has been shown to result in greater biomass, abundance, and size of limpets and to counter other negative anthropogenic effects. However, inefficient planning and lack of surveillance hinder the accomplishment of the conservation purpose of MPAs. Inclusive conservation approaches involving all the stakeholders could guarantee future success of conservation strategies and sustainable exploitation. This review also aims to establish how beneficial MPAs are in enhancing recruitment and yield of adjacent exploited populations

    Shortcut fusion rules for the derivation of circular and higher-order programs

    Get PDF
    Functional programs often combine separate parts using intermediate data structures for communicating results. Programs so defined are modular, easier to understand and maintain, but suffer from inefficiencies due to the generation of those gluing data structures. To eliminate such redundant data structures, some program transformation techniques have been proposed. One such technique is shortcut fusion, and has been studied in the context of both pure and monadic functional programs. In this paper, we study several shortcut fusion extensions, so that, alternatively, circular or higher-order programs are derived. These extensions are also provided for effect-free programs and monadic ones. Our work results in a set of generic calculation rules, that are widely applicable, and whose correctness is formally established.Fundação para a Ciência e a Tecnologi

    Influence of Prior Exercise on VO2 Kinetics Subsequent Exhaustive Rowing Performance

    Prior exercise has the potential to enhance subsequent performance by accelerating the oxygen uptake (VO2) kinetics. The present study investigated the effects of two different intensities of prior exercise on pulmonary VO2 kinetics and exercisetime during subsequent exhaustive rowing exercise. It was hypothesized that in prior heavy, but not prior moderateexercise condition, overall VO2 kinetics would be faster and the VO2 primary amplitude would be higher, leading to longerexercise time at VO2max. Six subjects (mean 6 SD; age: 22.964.5 yr; height: 181.267.1 cm and body mass: 75.563.4 kg)completed square-wave transitions to 100% of VO2max from three different conditions: without prior exercise, with priormoderate and heavy exercise. VO2 was measured using a telemetric portable gas analyser (K4b2, Cosmed, Rome, Italy) andthe data were modelled using either mono or double exponential fittings. The use of prior moderate exercise resulted in afaster VO2 pulmonary kinetics response (t1 = 13.4163.96 s), an improved performance in the time to xhaustion(238.8650.2 s) and similar blood lactate concentrations ([La2]) values (11.861.7 mmol.L21) compared to the onditionwithout prior exercise (16.065.56 s, 215.3660.1 s and 10.761.2 mmol.L21, for t1, time sustained at VO2max and [La2], respectively). Performance of prior heavy exercise, although useful in accelerating the VO2 pulmonary kinetics responseduring a subsequent time to exhaustion exercise (t1 = 9.1861.60 s), resulted in a shorter time sustained at VO2max(155.5646.0 s), while [La2] was similar (13.561.7 mmol.L21) compared to the other two conditions. Although both priormoderate and heavy exercise ulted in a faster pulmonary VO2 kinetics response, only prior moderate exercise lead to improved rowing performance.info:eu-repo/semantics/publishedVersio

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Elétrica.As rodovias próximas aos centros urbanos caracterizam-se por um fluxo intenso e um número relativamente grande de acessos laterais para a entrada e saída de veículos. Nos momentos de pico, algumas regiões próximas a esses acessos tornam-se congestionadas, pois o fluxo de veículos que sai do trecho de rodovia que possui o acesso é menor do que a capacidade desse trecho. Esse congestionamento ocorre em virtude de dois motivos: restrição física da capacidade da rodovia e restrição temporária em razão da dinâmica do tráfego. A restrição temporária em virtude da dinâmica do tráfego pode ser evitada com o uso do controle do tráfego de veículos em rodovias por meio do controle de acesso (ramp metering), que faz o fluxo de veículos na rodovia atingir o seu valor ótimo. Esta dissertação apresenta um estudo do controle de acesso em rodovias. Com base na análise de deficiências do comportamento de um simulador microscópico comercial, é feita a proposição de um modelo microscópico de simulação capaz de representar o fenômeno da redução dinâmica de capacidade. Usando como ferramenta o modelo de simulação proposto, é estudada a aplicação do algoritmo ALINEA em diferentes situações de entrada de veículos em rodovia de pista simples. Os resultados da simulação indicam que o controle de acesso em rodovias pode evitar ou amenizar o fenômeno da redução dinâmica da capacidade

    Today any OEM automotive industry that wants a status of a world-class organization has to follow a proper supplier quality management based on the worldwide recognized international standards. With this, the customer within a supply chain should have the sureness that the company has supplier capabilities in place to provide a service that consistently meets its needs and expectations. Although some of this Supplier Quality Management Systems (SQMS) are deeply integrated and used inside of an organization, sometimes they are implemented using inappropriate or limited tools, making the work of employees harder and acting often as entropy sources in those systems. Having the right tools to handle Inspections as well as Nonconformance, Complaint, Corrective Action and Concession processes is key to successfully track the supplier performance. This paper presents a platform to support a SQMS, that fits the technical specification ISO/TS 16949 requirements.info:eu-repo/semantics/publishedVersio
