UT Fire, a preprocessor for SAFIR2007, for analysis of heat transfer for structural members exposed to fireJennings, Timothy Mark 24 August 2010 (has links)
This thesis describes the development of the computer program UT Fire, which serves as a preprocessor for the computer program SAFIR2007. SAFIR2007, developed at the University of Liege in Belgium, conducts heat transfer analysis and structural response analysis for structures subjected to fire. The preprocessor UT Fire was developed to allow a simplified graphical interface for input to the heat transfer portion of SAFIR 2007. This thesis provides step by step instructions on the use of UT Fire and illustrates its use through a series of detailed examples. / text

Previous issue date: 2014 / INES, CNPq / Diante do ambiente complexo e dinâmico encontrado nas empresas atualmente, o sistema tradicional
de Workflow não está sendo flexível suficiente para modelar Processos de Negócio.
Nesse contexto, surgiram os Processos Flexíveis que tem por principal objetivo suprir a necessidade
de modelar processos menos estáticos. Processo declarativo é um tipo de processo
flexível que permite os participantes decidirem a ordem em que as atividades são executadas
através de regras de negócio. As regras de negócio determinam as restrições e obrigações que
devem ser satisfeitas durante a execução. Tais regras descrevem o que deve ou não deve ser
feito durante a execução do processo, mas não definem como. Os métodos e ferramentas atualmente
disponíveis para modelar e executar processos declarativos apresentam várias limitações
que prejudicam a sua utilização para este fim. Em particular, a abordagem que emprega lógica
temporal linear (LTL) sofre do problema de explosão de estados a medida que o tamanho
do modelo do processo cresce. Embora mecanismos eficientes em relação a memória terem
surgido, eles não são capazes de adequadamente garantir a conclusão correta do processo, uma
vez que permitem o usuário alcançar estados proibidos ou que causem deadlock. Além disso,
as implementações atuais de ferramentas para execução de processos declarativos se concentram
apenas em atividades manuais. Comunicação automática com aplicações externas para
troca de dados e reutilização de funcionalidade não é suportado. Essas oportunidades de automação
poderiam ser melhor exploradas por uma engine declarativa que se integra com tecnologias
SOC existentes. Este trabalho propõe uma nova engine de regras baseada em grafo,
chamado de REFlex. Tal engine não compartilha os problemas apresentados pelas abordagens
disponíveis, sendo mais adequada para modelar processos de negócio declarativos. Além
disso, REFlex preenche a lacuna entre os processos declarativos e SOC. O orquestrador REFlex
é um orquestrador de serviços declarativo, eficiente e dependente de dados. Ele permite
que os participantes chamem serviços externos para executar tarefas automatizadas. Diferente
dos trabalhos relacionados, o algoritmo de REFlex não depende da geração de todos os estados
alcançáveis, o que o torna adequado para modelar processos de negócios grandes e complexos.
Além disso, REFlex suporta regras de negócio dependentes de dados, o que proporciona sensibilidade
ao contexto. / Declarative business process modeling is a flexible approach to business process management
in which participants can decide the order in which activities are performed. Business rules are
employed to determine restrictions and obligations that must be satisfied during execution time.
Such business rules describe what must or must not be done during the process execution, but
do not prescribe how. In this way, complex control-flows are simplified and participants have
more flexibility to handle unpredicted situations. The methods and tools currently available to
model and execute declarative processes present several limitations that impair their use to this
application. In particular, the well-known approach that employs Linear Temporal Logic (LTL)
has the drawback of the state space explosion as the size of the process model grows. Although
approaches proposing memory efficient methods have been proposed in the literature, they are
not able to properly guarantee the correct termination of the process, since they allow the user
to reach deadlock states. Moreover, current implementations of declarative business process
engines focus only on manual activities. Automatic communication with external applications
to exchange data and reuse functionality is barely supported. Such automation opportunities
could be better exploited by a declarative engine that integrates with existing SOC technologies.
This work proposes a novel graph-based rule engine called REFlex that does not share
the problems presented by other engines, being better suited to model declarative business processes
than the techniques currently in use. Additionally, such engine fills this gap between
declarative processes and SOC. The REFlex orchestrator is an efficient, data-aware declarative
web services orchestrator. It enables participants to call external web services to perform
automated tasks. Different from related work, the REFlex algorithm does not depend on the
generation of all reachable states, which makes it well suited to model large and complex business
processes. Moreover, REFlex is capable of modeling data-dependent business rules, which
provides unprecedented context awareness and modeling power to the declarative paradigm.

Responsivní webdesign / Responsive Web DesignHavelka, Petr January 2013 (has links)
The aim of the thesis is to create a comprehensive material that covers the basic knowledge of theory and practices necessary to understand the whole complexity of the Responsive Web Design (RWD). This thesis first focuses on the RWD origin and its two approaches. Furthermore, the work deals with technical solutions of the RWD and technologies that enabled its creation or were found useful for it. This part also mentions tools which simplify the work with given technologies. The next part is devoted to Responsive CSS Frameworks as being the base for creating responsive websites and shows layout examples where two different approaches and frameworks were used. At last an issue of testing responsive websites is discussed.

Flexible Engineering Software: An Integrated Workstation Approach to Finite Element AnalysisRoss, Brant Arnold 01 April 1985 (has links) (PDF)
One obstacle preventing more engineers from using finite element analysis (FEA) is the difficulty of transferring data between steps in the modeling process. A Fortran computer program, Rosetta.BYU, has been developed to open data paths between finite element preprocessors (mesh generators) and finite element analysis programs, using a custom data structure. It accepts neutral data files, Version 2.0 IGES data files, and Movie.BYU files for input/output. An application of Rosetta is described. A general workstation manager program, Davinci.BYU, is reviewed that provides a support layer between the engineer and the operating system, organizes software and data files, and facilitates on-line documentation and demonstrations. Requirements of a good user interface are discussed and supporting software, Squire.BYU, is described. An application of this software in an industrial setting is described.
