Indexing with images applied to the FRSAD model : a conceptual methodology

Evento realizado pela Associação Nacional de Pesquisa em Ciência da Informação (ANCIB) e organizado pelo Programa de Pós-Graduação em Ciência da Informação da Universidade Federal da Bahia (PPGCI/UFBA).Este trabalho associa a metodologia de indexação por imagens com o modelo FRSAD como um mecanismo compatível para o compartilhamento global da informação e uso de dados de assunto, ambos no contexto da Biblioteconomia e afins. O modelo conceitual da indexação imagética mostra como as imagens estão relacionadas aos tópicos e “imagens-chave” são interpretadas com nomens para implementar o modelo FRSAD. A indexação por imagens consiste em usar imagens em lugar de palavras-chave ou descritores para representar e organizar informações. A implementação da navegação em OPACs nesta perspectiva significa inovar o OPAC quando se procura compartilhar conceitos de autoridades assunto. Na prática isto inclui a tradução de metadados, tesauros multilingues simétricos, ou qualquer outra forma tradicional de ferramentas de indexação. A proposta de iOPAC (OPAC imagético) incorpora esforços concentrados em níveis conceituais tal como esperado pelos bibliotecários. Interfaces imagéticas são mais intuitivas quando os usuários dispensam treinamento para a recuperação da informação oferecendo uma compreensão facilitada dos códigos de indexação, ampla portabilidade conceitual dos descritores (como imagens), e melhor interoperabilidade entre os códigos do discurso e as competências em indexação, afetando positivamente a interoperabilidade social e cultural. A metodologia imagética encontra aplicações em P&D para criar interfaces mais conviviais considerando usuários com necessidades especiais, tais como indivíduos com surdez ou iletrismo funcional. Esta metodologia levanta questões sobre os paradigmas da primazia da oralidade em sistemas de informação e pavimenta o caminho para a legitimidade de perspectivas múltiplas na indexação de documentos, sugerindo uma comunicação mais universal baseada em imagens. Aspectos interdisciplinares das neurociências, linguística e ciências da informação são competências requisitadas para futuras investigações sobre a natureza dos processos cognitivos na organização e classificação da informação, para o desenvolvimento de sistemas assistivos de organização do conhecimento para indivíduos com limitações no processo de comunicação, tais como a surdez e o autismo.This proposal associates the methodology of indexing with images with the FRSAD model as a compatible mechanism for a global information share and use of subject data, both within the library sector and beyond. The conceptual model of imagetic indexing shows how images are related to topics and ‘key-images’ are interpreted as nomens to implement the FRSAD model. Indexing with images consists of using images instead of key-words or descriptors, to represent and organize information. Implementing the imaged navigation in OPACs denotes multiple advantages derived from this means rethinking the OPAC anew, since we are looking forward to sharing concepts within the subject authority data. Images, carrying linguistic objects, permeate inter-social and cultural concepts. In practice it includes translated metadata, symmetrical multilingual thesaurus, or any traditional indexing tools. The imaged OPAC (iOPAC) embodies efforts focused on conceptual levels as expected from librarians. Imaged interfaces are more intuitive since users do not need specific training for information retrieval, offering easier comprehension of indexing codes, larger conceptual portability of descriptors (as images), and a better interoperability between discourse codes and indexing competences affecting positively social and cultural interoperability. The imagetic methodology deploys R&D fields for more suitable interfaces taking into consideration users with specific needs such as deafness and illiteracy. This methodology arouse questions about the paradigms of the primacy of orality in information systems and pave the way to a legitimacy of multiple perspectives in document indexing by suggesting a more universal communication system based on images. Interdisciplinarity in neurosciences, linguistics and information sciences would be desirable competencies for further investigations about the nature of cognitive processes in information organization and classification while developing assistive KOS for individuals with communication problems, such autism and deafness

Fractional variational calculus for nondifferentiable functions

We prove necessary optimality conditions, in the class of continuous functions, for variational problems defined with Jumarie's modified Riemann-Liouville derivative. The fractional basic problem of the calculus of variations with free boundary conditions is considered, as well as problems with isoperimetric and holonomic constraints.Comment: Submitted 13-Aug-2010; revised 24-Nov-2010; accepted 28-March-2011; for publication in Computers and Mathematics with Application

Fractional Euler-Lagrange differential equations via Caputo derivatives

We review some recent results of the fractional variational calculus. Necessary optimality conditions of Euler-Lagrange type for functionals with a Lagrangian containing left and right Caputo derivatives are given. Several problems are considered: with fixed or free boundary conditions, and in presence of integral constraints that also depend on Caputo derivatives.Comment: This is a preprint of a paper whose final and definite form will appear as Chapter 9 of the book Fractional Dynamics and Control, D.

Isoperimetric problems of the calculus of variations with fractional derivatives

In this paper we study isoperimetric problems of the calculus of variations with left and right Riemann-Liouville fractional derivatives. Both situations when the lower bound of the variational integrals coincide and do not coincide with the lower bound of the fractional derivatives are considered.Comment: Submitted 02-Oct-2009; revised 30-Jun-2010; accepted 10-May-2011; for publication in the journal Acta Mathematica Scienti

Chiral Capillary Electrokinetic Chromatography: Principle and Applications, Detection and Identification, Design of Experiment, and Exploration of Chiral Recognition Using Molecular Modeling

Zoneamento Agroclimático para a Cultura da Soja no Leste do Estado do Pará.

In order to determine reasonable planting time and zoning for soybean in the regions of Northeast and Southeast Pará, water ballance simulation and a zoning approach were conduced. Water balance was analysed by using combinations of 12 planting time, soil available water and two crop varieties. In adition, field informations related to soil texture, plant phenology and crop water consumption were also analysed. From water balance several paramaters were determined including the moisture satisfaction index (HNSI) and climatic risks. The zoning approach was based on two aspects: the climatic risks as an indicator to determine the climatic suitability classes for soybean and the geographic system analyses(GIS) for spatial analysis. The overall results show 72 zoning maps indicanting favorable planting time and suitable areas for soybean crop
