Development of the RIOT Web Service and Information Technologies to enable mechanism reduction for HCCI simulations.
Abstract. New approaches are being explored to facilitate multidisciplinary collaborative research of Homogenous Charge Compression Ignition (HCCI) combustion processes. In this paper, collaborative sharing of the Range Identification and Optimization Toolkit (RIOT) and related data and models is discussed. RIOT is a developmental approach to reduce the computational of detailed chemical kinetic mechanisms, enabling their use in modeling kinetically controlled combustion applications such as HCCI. These approaches are being developed and piloted as a part of the Collaboratory for Multiscale Chemical Sciences (CMCS) project. The capabilities of the RIOT code are shared through a portlet in the CMCS portal that allows easy specification and processing of RIOT inputs, remote execution of RIOT, tracking of data pedigree, and translation of RIOT outputs to a table view and to a commonly-used mechanism format. Introduction The urgent need for high-efficiency, low-emission energy utilization technologies for transportation, power generation, and manufacturing processes presents difficult challenges to the combustion research community. The needed predictive understanding requires systematic knowledge across the full range of physical scales involved in combustion processes -from the properties and interactions of individual molecules to the dynamics and products of turbulent multi-phase reacting flows. Innovative experimental techniques and computational approaches are revolutionizing the rate at which chemical science research can produce the new information necessary to advance our combustion knowledge. But the increased volume and complexity of this information often makes it even more difficult to derive the systems-level knowledge we need. Combustion researchers have responded by forming interdisciplinary communities intent on sharing information and coordinating research priorities. Such efforts face many barriers, however, including lack of data accessibility and interoperability, missing metadata and pedigree information, efficient approaches for sharing data and analysis tools, and the challenges of working together across geography, disciplines, and a very diverse spectrum of applications and funding. This challenge is especially difficult for those developing, sharing and/or using detailed chemical models of combustion to treat the oxidation of practical fuels. This is a very complex problem, and the development of new chemistry models requires a series of steps that involve acquiring and keeping track of a large amount of data and its pedigree. Also, this data is developed using a diverse range of codes and experiments spanning ab initio chemistry codes, laboratory kinetics and flame experiments, all the way to reacting flow simulations on massively parallel computers. Each of these processes typically requires different data formats, and often the data and/or analysis codes are only accessible by personally contacting the creator. Chemical models are usually shared in a legacy file format, such as Chemki
A cultura polÃtica em Porto Alegre e Curitiba: democracia, modernização e o conteúdo da razão pública Political culture in Porto Alegre and Curitiba: democracy, modernization and the content of public reason
Este estudo compara certas caracterÃsticas básicas da cultura polÃtica nas cidades de Curitiba e Porto Alegre, analisando as suas diferenças e convergências como formas locais complementares de manifestação da conquista da cidadania, em distintos contextos histórico-sociais, durante o processo de democratização da esfera pública. Este trabalho se opõe aos estudos empÃricos convencionais da cultura polÃtica, inspirados nas teorias da modernização, argumentando contra o viés determinista desses estudos, e os procedimentos de hipergeneralização por eles geralmente adotados. O estudo argumenta por uma abordagem que retrate e interprete o pluralismo constitutivo da cultura polÃtica, expresso no exercÃcio da cidadania durante os processos de democratização.<br>This is a comparative study of certain basic characteristics of political culture in the cities of Curitiba and Porto Alegre, analizing their diversity and convergence as local complementary forms of the constitution of citizenship. These differences are related to their socio-historical context during the processes of democratization of the public sphere. This work argues against the usual deterministic bias and over-generalization procedures of conventional empirical studies of political culture oriented by modernization theories. The present study argues for an approach that portrays and interprets the pluralistic constitution of political culture expressed through the exercise of citizenship during the processes of democratization
