International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A particular engineering aspect of distributed sensor networks that has not received adequate attention is the system level hardware architecture of the individual nodes of the network. A novel hardware architecture based on an idea of task specific modular computing is proposed to provide for both the high flexibility and low power consumption required for distributed sensing solutions. The power consumption of the architecture is mathematically analyzed against a traditional approach, and guidelines are developed for application scenarios that would benefit from using this new design.

O rápido avanço tecnológico nestes últimos anos, principalmente dos recursos computacionais e de comunicação, permite que os sistemas produtivos (SP) evoluam tanto no seu aspecto estrutural quanto no comportamental para que atendam às necessidades crescentes do mercado. Os elementos integrantes dos SP vêm incorporando estes avanços, atingindo maior autonomia e flexibilidade p ara cumprir suas funcionalidades. Além disso, a tendência dos dispositivos de controle de incorporar a capacidade de atuação em ambientes distribuídos onde a interação ocorre através de redes de comunicação, verificada na evolução das normas aplicadas a sistemas de controle, reflete a necessidade de aderência dos sistemas de controle a essa realidade. A necessidade de se manter competitivo no mercado impõe aos atuais SP situações em que emergem novos desafios para realização do controle dos seus processos globais, uma vez que estes assumem múltiplos objetivos, envolvendo diferentes naturezas de indeterminismo, assincronismo e variância no tempo, provocando um nível de complexidade inédito no que se refere ao controle destes sistemas. Este trabalho propõe inicialmente uma nova abstração para modelar-se os SP baseada no conceito de decomposição multidimensional e em múltiplas faces, distribuindo o controle através dos componentes colaborativos. Feito isto, são propostos procedimentos e técnicas para modelagem de sistemas de controle distribuídos e colaborativos (SCDC) de SP. Considera-se para isso, primeiro, uma arquitetura lógica de controle que contemple os múltiplos domínios semânticos presentes em SP, que são provenientes das especificidades dos elementos integrantes. Segundo, a multiplicidade de habilidades necessárias para garantir a execução das estratégias de controle pertinentes a cada domínio. Terceiro, o fluxo de informações heterogêneas provenientes das interações colaborativas entre os domínios. / Recent technological advances, mainly of computer and communication systems, allow the production systems (SP) to evolve in structural aspect as well as in behavioral aspect. The SP resources have achieved enhanced autonomy and flexibility with embedded computer and communication capability. Latest trends of control devices, as seen in the evolution of standards related to control systems, focus on the use of these devices in a distributed environment, where interaction occur through a communication network Thus, the SP control system and its design methods have to fit to this reality. In a competitive scenario, the SP are challenged to keep control of the global processes, considering the multiple goals of these processes and the involvement of different aspect of indeterminism, lack of synchronisms and time variance, generating a inedited complexity level for control of this systems. This work proposes a new abstraction for modeling the control systems of SP, based on the concept of multidimensional decompositions. Based on this, it introduces the procedures and techniques for modeling the distributed and collaborative control systems (SCDC) of the production systems. First, it considers the logic architecture of the control that support many semantic domains presented in this type of SP. Then, the diversity of skills related to each domain necessary to accomplish the control strategies. And then, the heterogeneous information flow through the domains boundaries, derived from the collaborative interaction between the control components.

Pastaruoju metu informacinių technologijų pasaulyje dažnai minimos paslaugomis ir įvykiais grindžiamų sistemų architektūros. Greitai besikeičiančiame verslo pasaulyje įmonėms yra aktualu turėti sistemas, kurios greitai ir lengvai būtų priderintos prie besikeičiančių verslo procesų ir sumažintų tokių sistemų kūrimo ir palaikymo išlaidas. Naudodamos paslaugomis grindžiamą architektūrą, įmonės gali lanksčiai tvarkyti savo veiklą ir kurti sistemas, nekeisdamos turimos techninės ar programinės įrangos. Nors literatūroje yra gausu straipsnių apie įvykiais grindžiamas sistemas ir jų privalumus, tačiau sistemos architektui, nusprendusiam sukurti įvykiais grindžiamos sistemos projektą, iškyla aktualus klausimas: kaip aprašyti ir modeliuoti įvykius, kurie ateina iš išorės arba sugeneruojami pačios sistemos ar vartotojų veiksmų su sistema metu. Akivaizdu, kad šiuo metu nėra populiarios metodikos, kuri apibrėžtų, kaip reikia atlikti įvykių modeliavimą ir jį panaudoti informacinių sistemų kūrimo procese. Šiame darbe nagrinėjami įvykiais grindžiamų sistemų modeliavimo metodai ir realizavimo technologijos. Atsižvelgiant į analizės rezultatus pateikiama įvykiais grindžiamų sistemų modeliavimo ir realizavimo metodika. Ši metodika pritaikyta ir įvertinta sukuriant publikacijų portalo prototipą. / Nowadays the terms SOA (Service Oriented Architecture) and event driven systems are often used when talking about systems with large scalability, performance and interoperability. In fast changing business world it is vital to have systems that could be easily changed whenever new functionality is needed. Using service oriented architecture companies can easier adapt its business process to changed business rules. Even though there are a lot of articles and publications about event driven systems and their advantages, but the system architect who decides to build an event driven system is facing the problem: how to model and describe events of the system. Obviously, that there are no popular and widely accepted methodology for event driven system modelling. The goal of this work is to develop a methodology for modelling an event driven systems. This methodology describes the metamodel for event modelling and the usage of the event model in system development life cycle. The developed methodology for modelling and implementation of event-driven information systems was used for making a model of publications portal prototype. Usage of this methodology in system design process adds more clarity, because all the events, which can be generated in the system and their types, are described in one diagram – event model. The event model elements can be used in other model diagrams, such as sequence or state machine diagrams.

Main focus of the thesis lies in the corporate management decision support deploying and using IT / ICT. Specific technology described is Business Activity Monitoring. The contribution of the work lies primarily in two planes. The first plane is to create as far as the most comprehensive view of the BAM. The findings are collected from different directions and areas. The first direction of research is focused on the development of Business Intelligence and description of BAM as a trend of BI, including the stages of development and projections into the future. The second direction focuses primarily on a detailed circumscribe of BAM. Its definition, deployment assumptions, basic models, the way how business can benefit from BAM usage. The third guideline shows the classification of BAM surrounded by the other / similar technologies and business solutions -- BI and BSM, and the search key differences. The second level of the work is to support the AML implementation in a specific environment of banks using BAM. This is a practical demonstration of the possibility of using BAM in practice. Basic design solution lies in the analysis of risks arising from the law and the current state of the solution. By mapping of banking processes and searching for points of risk it is then possible to deploy these risks BAM tools for their management. Motion of support lies mainly in conceptual terms.
