We describe CoSMo, a Cognitively Inspired Service and Model Architecture for situational awareness and monitoring of vehicular traffic in urban transportation systems using a network of wireless sensors. The system architecture combines (i) a cognitively inspired internal representation for analyzing and answering queries concerning the observed system and (ii) a service oriented architecture that facilitates interaction among individual modules, of the internal representation, the observed system and the user. The cognitively inspired model architecture allows one to effectively respond to deductive as well as inductive queries by combining simulation based dynamic models with traditional relational databases. On the other hand the service oriented design of interaction allows one to build flexible, extensible and scalable systems that can be deployed in practical settings. To illustrate our concepts and the novel features of our architecture, we have recently completed a prototype implementation of CoSMo. The prototype illustrates advantages of our approach over other traditional approaches for designing scalable software for situational awareness in large complex systems. The basic architecture and its prototype implementation are generic and can be applied for monitoring other complex systems. CoSMo's architecture has a number of features that distinguish cognitive systems. This includes: dynamic internal models of the observed system, inductive and deductive learning and reasoning, perception, memory and adaptation. This thesis describes the service oriented model and the associated prototype implementation. Two important contributions of this thesis include the following: The Generic Service Architecture - CoSMo's service architecture is generic and can be applied to many other application domains without much change in underlying infrastructure. Integration of emerging web technologies - Use of Web Services, UPnP, UDDI and many other emerging technologies have taken CoSMo beyond a prototype implementation and towards a real production system. / Master of Science

This report describes the development and testing of the upgraded Control and Monitoring (C&Mu) system for the TOFOR neutron spectrometer. TOFOR is currently performing plasma diagnostics for the JET experimental fusion reactor. The purpose of the C&Mu system is to enable monitoring of the amplitude dependent time delays of TOFOR. In order to perform this monitoring function the C&Mu system must comprise a pulsed light source with variable intensity and a reference time signal. In this work a reference time signal has been retrieved from a laser comprising a motorized polarizer. This has been accomplished by installing a photomultiplier tube and a beamsplitter cube. The beamsplitter cube splits the laser light into two parts and directs one part into the photomultiplier tube. The photomultiplier tube converts the light into an electrical reference time signal. A control program has been developed for the motorized polarizer, enabling the user to vary the intensity of the light over the interval from 0% to 100%. The C&Mu system has been performance tested and it was found that the time resolution of the system is about 0.1ns and the time stability of the system is about 0.12ns over 27 hours. The system is more than adequate to monitor variations in time delays at TOFOR of several nanoseconds, over a full JET day. The C&Mu system is ready to be installed on TOFOR.

M. Tech. (Department of Process Control and Computer Systems, Faculty of Engineering and Technology), Vaal University of Technology. / The telecommunication and utility cable monitoring system was implemented to protect the cable tampering. Cable tampering occurs despite the fact that methods have been developed, to solve and decrease cable tampering cases such as cable tampering prevention campaigns at the national and international level, organizing security patrols, replacing existing cable with fiber cables and I-Watch system installation. The objective of the research was to design and implement a cable tampering monitoring system which is able to monitor, detect, pinpoint the location and give the distance from the sensor at which the cable tampering took place. The system is an improvement on the traditional cable anti-theft monitoring system, the method of tracking resonance signal frequency was implemented. The system incorporates a sensing circuit which detects a change on the capacitance value of the cable and converts it into an equivalent frequency value, Field-Programable Gate Array (FPGA) board is utilized to convert the frequency into the cable length (the distance from sensor of cable which was taken away), after detecting an anomaly on the cable (tampered with) the output of the system is divided into two parts which are display mode and messaging mode. For display mode, the system uses a Liquid Crystal Display (LCD) which displays the GPS Coordinates of the location where the cable tampering took place and the distance from sensor of the cable which has been tampered with. In the messaging mode, the FPGA activates the GSM module and the module sends alert flag message to the user when the cable is tampered with.

Vid nybyggnation eller modernisering av fartyg installeras ofta avancerade integrerade övervakningssystem i maskinkontrollrum. Det är därför viktigt att de maskinbefäl som ansvarar för driften av fartyget innehar en utbildning och kunskap om hantering och felsökning av övervakningssystemen. Syftet med studien är att undersöka om maskinbefäl får tillräckligt med utbildning på nya integrerade övervakningssystemen för att utföra sina arbetsuppgifter på ett säkert och tryggt sätt. I den här studien har en enkät skickats ut till maskinbefäl ombord nybyggda fartyg där individerna får möjlighet att svara på hur de upplever möjlighet att genomgå utbildning och få kunskap över hur systemen fungerar. Studien visar att majoriteten av de tillfrågade befälen upplever att de innehar tillräcklig kunskap om övervakningssystemen för att kunna utföra sina arbetsuppgifter på ett säkert och tryggt sätt. Studien visar att majoriteten av befälen inte har blivit erbjudna en utbildning på systemen och att de som inte blivit erbjudna hade önskat få en utbildning. Studien visade att utbildningarna som erbjudits ofta är produktspecifika och inte installationsspecifika vilket gör att de inte upplevs som optimala då konstruktion och lösningar ofta avviker emellan installationer med samma produkter. Utbildning erbjuds av tillverkaren men ofta är det bara en liten del av maskinbefälen som erbjuds en plats. Studien visade också att de befäl som inte fick utbildning behövde tillskansa kunskaperna genom att själv utbilda sig ombord antingen i samband med avlämning eller under ordinarie drift. Slutsatsen är att maskinbefälen bör genomgå en utbildning innan de mönstrar på första gången och att det bör ges möjlighet till en uppföljande utbildning efter att besättningen arbetat med systemen en tid. För att avlösande besättningar ska kunna få möjlighet att sätta sig in och tillgodogöra sig kunskap om systemen bör mer tid ges vid avlösning. / During construction of new ships or modernization of ships, integrated automation systems is often installed in the engine control room. It is of importance that the responsible engine officers are familiar with how the system works and that they can perform troubleshooting if eventual faults occur. The aim of the present study is to investigate whether the engineer officer get enough training on new integrated surveillance systems to perform their duties in a safe and secure manner. In this study a questionnaire was sent to engine officers signed on new ships where they got the opportunity to give their answer how they experience the possibility to be trained and acquire knowledge how the systems work. The majority of the engine officers who answered the questionnaires felt comfortable to operate the ship safely. The study showed that the training courses offered often were product specific instead of installation specific, which was not optimal because there can be differences between construction and handling after installations of the same products. The survey showed that a majority of the officers had not been offered training on the monitoring system. The officers who were not offered training expressed a wish to be able to participate in training. Training on the system is offered by the manufacturer but often only a few of the engine officers is offered training by the shipping company. Earlier studies show that crews that participates in the building and delivery process on the shipyard or during installation of a new system receives training on site, the officers that come onboard as reliever after trial run, maiden voyage or during normal operation often have to learn by doing. The conclusion is that the officers should be given the opportunity to participate in training before signing on and also a follow up training course after working with the system for a while. To give the relieving officers a chance to familiarize themselves and assimilate knowledge of the system, there have to be more time available in conjunction with leave.

Acredita-se que a integração entre estas duas áreas é fundamental para se alcançar a integralidade da atenção, um dos princípios do Sistema Único de Saúde. O município escolhido tem investido em inovações gerenciais, contando com a presença do apoiador institucional, que valoriza as ações intersetoriais, buscando a articulação entre as diversas áreas do sistema de saúde e de outros setores fora dele. Espera-se que esta opção favoreça a integração entre a Atenção Básica e a Vigilância em Saúde. O estudo teve como objetivo conhecer os entraves existentes e as conquistas já vivenciadas durante o processo de integração entre a Atenção Básica e a Vigilância em Saúde em um município da região metropolitana de Porto Alegre/RS. O delineamento da pesquisa é o Estudo de Caso. As técnicas de pesquisa utilizadas foram a entrevista semiestruturada, o grupo de discussão focal e a pesquisa documental. A análise interpretativa chamada de hermenêutica dialética foi a técnica utilizada nesse estudo para a análise dos dados. Verificou-se que grande parte das ações de vigilância epidemiológica foi descentralizada e é executada pela Atenção Básica (AB). A vigilância ambiental é a área com menos ações descentralizadas e atividades realizadas de forma conjunta. O território da AB é respeitado pelos servidores da Vigilância em Saúde. O maior desafio encontrado para a integração entre a AB e a vigilância foi a troca de servidores não estáveis por funcionários concursados em 2012. Em torno de 80% dos servidores da Atenção Básica precisou ser substituído. Tal quadro se refletiu na rotina de trabalho e na integração entre as áreas. O quadro funcional ainda sofre alterações. Sabe-se que vai levar algum tempo para que a rede esteja novamente completa. Entretanto, passado esse período difícil, acredita-se que funcionários estáveis e com plano de carreira definido se fixem, o que tornaria a rotatividade bem menos frequente. Por isso, pensa-se que o cenário futuro tende a ser melhor do que era antes da troca de funcionários e que o processo de integração tenda a se efetivar. / This study aimed to learn about the status of the integration process between the Primary Health Care and the Health Monitoring System in a city of the metropolitan area of de Porto Alegre/RS. It is believed that the integration between such areas is fundamental for the integrality of Health Care, one of the principles of the Unified Health System. The chosen city has invested in management innovation, relying on the presence of the intitutional supporter, who prioritizes intersectoral actions, seeking articulation among the several areas of the health care system as well as of other segments external to it. It is expected that such option favors the integration between the Primary Health Care and the Health Surveillance. This study had the intent of making known the existing obstacles and the conquests already experienced throughout the integration process between the Primary Health Care and the Health Surveillance in a city of the metropolitan area of de Porto Alegre/RS. The outline of the research is based on a Case Study method. The survey techniques used were: semi-structured interview, focus group discussion, and desk research. The interpretative analysis type called Dialectical Hermeneutics was the technique used in the group for the data analysis. It has been demonstrated that the integration process between the Primary Health Care and the Health Surveillance in the city is at an advanced stage. Most of the actions are already done conjunctively and the territory of the Basic Health Care is respected by the workers in the Health Surveillance. The greatest challenge for the integration of the Primary Health Care and the Health Surveillance was the exchange of non-tenured workers for long-tenured ones in 2012. About 80% of the workers in Primary Health Care needed to be replaced. Such scenario reflected on the work routine and on the integration between the areas. The staff are still undergoing changes. Still, it is known that it will be a long time until the network is again settled. Nevertheless, after such a difficult time, it is believed that the long-tenured workers with a career plan will end up settling down, making the turnover quite less frequent. For that reason, it is thought that the future prospect tends to be better than it was before the replacement of workers and that the integration process is prone to be achieved.

O escoamento entre o poço marítimo e a unidade flutuante é realizado através de dutos definidos como risers. Os risers flexíveis são compostos por camadas intercaladas de diferentes materiais, como aço e polietileno, o qual cada camada possui uma função. Os mecanismos de falha mais reportados são referentes a danos na camada externa polimérica, o que leva à exposição de suas armaduras metálicas ao meio externo. Os risers rígidos são dutos fabricados normalmente em aço, formados por segmentos de dutos unidos por soldas, onde a causa de dano mais frequente é a corrosão. Tem-se como objetivo nesta dissertação, o projeto e desenvolvimento de uma ferramenta e de um método para operações submarinas em risers. A ferramenta deverá ser capaz de aplicar de forma automática, um clamp bipartido no reparo da camada externa polimérica de risers flexíveis, ou acoplar sistemas de monitoramento em risers rígidos. Já o método, deverá permitir a sua aplicação tanto no reparo quanto na proteção do sistema de monitoramento. Para isto, realizou-se uma revisão bibliográfica a fim de obter uma melhor compreensão sobre o tema estudado. Desenvolveu-se o projeto do método e da ferramenta, e, posteriormente, construiu-se o protótipo para a realização de testes de funcionamento em um duto rígido Por último, através de ensaios hidrostáticos de pressão interna e externa, realizaram-se ensaios para avaliação do comportamento do método aplicado em um duto rígido. Os ensaios comprovaram a eficácia do clamp quando aplicado em ambientes submarinos em grandes profundidades, porém apresentou vazamentos nos ensaios de pressão interna e externa. A resina epóxi utilizada não garantiu a estanqueidade, possivelmente devido a sua alta rigidez, aderência ineficaz em superfícies metálicas, ou presença de vazios ou porosidades. O ensaio de pressão interna indicou que as deformações não ultrapassaram o regime elástico tanto do duto quanto do clamp até aproximadamente 182 bar de pressão. No regime elástico, o ensaio apresentou deformações menores no clamp em relação ao duto, possivelmente porque a resina acabou absorvendo as deformações. O método demonstrou ser eficiente como recipiente para a resina, e também permitiu a montagem e fixação de um colar de sensores no seu interior. Os testes de funcionamento mostraram que a ferramenta projetada e construída mostrou-se adequada para a aplicação automática de um clamp bipartido em risers, e o método mostrou-se adequado para sua aplicação em risers, tanto no reparo quanto na proteção do sistema de monitoramento. / The drain between the maritime oil well and the floating unit is made trough pipes, which is defined as risers. The flexible risers are composed by alternate layers from different materials as steel and polyethylene, each layer has its function. The failure mechanisms more reported are referent to the damage in the external polymeric layer which leads to the exposition of the metal armature to the outside. The rigid risers are pipes usually fabricated in steel made by ducts segments connect by spot welding, where the most common damage is corrosion. This essay aims to project and create a tool and a method for submarine operations in risers. The tool must be able to apply, in an automatic way, a bipartite clamp in the repair of the flexible rises in external polymeric layer or to attach monitoring systems to the rigid risers. The method must allow its application in the repair as much as the monitoring system protection. For this, it was made a bibliographic review to obtain a better comprehension from the studied theme. A project from the method and a tool were developed, later a prototype was built to make the operation tests in a rigid pipe. At last, by internal and external pressure hydrostatic trials, were made tests to evaluate the behavior of the method applied in a rigid pipe The trials proved the efficiency of the clamps when applied in submarine environments and in depth; however there were leaks in the internal and external pressure tests. The Epóxi resin did not guarantee the leak-tightness, possible due to its hardness, ineffective adherence in metal surfaces or presence of gaps and porosities. The internal pressure trial indicated that the deformations did not exceed the elastic regime in the pipe as in the clamp until, about 182 pressure bar. In the elastic regime, the trial presented minor deformation in the clamps related to the pipe possibly, because the resin absorbed the deformation. The method has proven efficient as recipient for the resin and also allowed the assembly and fixation of a sensor collar in its interior. The operation tests showed that the designed and built tool is proper for an automatic bipartite clamp application in risers and the method has proven proper for its application in risers in repair as much as monitoring system protection.

This study aimed to haracterize the biogas through a computer system (hardware and software), taking into account the two main gas composition, allowing in situ analysis, online and continuously, without human intervention in the process. For this, an experiment was conducted using electronic prototyping platform Arduino, which is fed with data from a sensor that uses non-dispersive infrared spectroscopy technology (NDIR). The results show that the system was efficient, once it is possible to monitor the concentration of CO2 and CH4 through real-time generated graphics. Moreover, it was possible to analyze the internal temperature of the anaerobic reactor through an integrated sensor to the monitoring system, which demonstrates its scalability, a desirable feature in computer systems. It was concluded also that the system detects the first signs of instability in the biodigestion process, allowing acceptable answers to establish countermeasures for its compensation. / O biogás, entendido como uma fonte alternativa de energia, é constituído por uma mistura de gases essencialmente metano (CH4) e por dióxido de carbono (CO2). Esta pesquisa teve como objetivo caracterizar o biogás por meio de um sistema computacional (hardware e software), levando em conta os dois principais gases de sua composição, possibilitando análise in situ, de forma online e contínua, sem a intervenção humana no processo. Para tal, foi desenvolvido um experimento utilizando a plataforma de prototipagem eletrônica Arduino, alimentada com dados de um sensor que utiliza a tecnologia de espectroscopia de infravermelho não dispersivo (NDIR). Os resultados apontam que o sistema desenvolvido foi eficiente, sendo possível o monitoramento da concentração de CO2 e CH4, por meio de gráficos gerados em tempo real. Além disso, foi possível analisar a temperatura interna do reator anaeróbio através de um sensor integrado ao sistema de monitoramento, que demonstra sua escalabilidade, uma característica desejável em sistemas computacionais. Pôde-se concluir, também, que o sistema detecta os primeiros indícios de uma instabilidade no processo de biodigestão, permitindo respostas aceitáveis no estabelecimento de contramedidas para sua compensação.

Considerable ongoing risk of condenser in-leakage exists at Otahuhu B (OTB) Power Station. The condenser cooling water used at OTB station is corrosive brackish water with exceedingly high sodium and chloride concentrations. Significant signs of corrosion inside the condenser have been found recently. In the event of condenser in-leakage, the salt contaminants in the cooling water will directly enter the Heat Recovery Steam Generator (HRSG) with the potential for significant and costly damage resulting in a long plant outage. A dynamic mathematical model was developed in the thesis to analyse the consequences of condenser in-leakage at OTB station. The analysis results show that the tolerance of the condenser to any leakage of cooling water is almost zero. Because the existing condensate monitoring system is not designed to detect contamination in this time frame, a new fast response system is required to detect condenser in-leakage immediately. A new dedicated fast response condensate monitoring system has been engineered and installed at OTB station as a part of the project scope. The new system dramatically reduces the response time to condenser in-leakage events. Critical instruments utilise multiple redundancy schemes to enhance the availability and reliability of the system. In addition, action level voting, timing, and alarming has been automated to assist operators in making correct decisions. The new condensate monitoring system is presently fully functional. The project has successfully achieved the objective of controlling the risk of condenser in-leakage events and minimising damage and negative effects on the plant.
