Modelling large-scale information systems using ADLs – An industrial experience report

An organisation that had developed a large information system wanted to embark on a programme that would involve large-scale evolution of it. As a precursor to this, it was decided to create a comprehensive architectural description to capture and understand the system’s design. This undertaking faced a number of challenges, including a low general awareness of software modelling and software architecture practices. The approach taken by the software architects tasked with this project included the definition of a simple, very specific, architecture description language. This paper reports our experience of the project and a simple ADL that we created as part of it.

Intelligent Distributed Environmental Decision Support System

This article discusses the development of an Intelligent Distributed Environmental Decision Support System, built upon the association of a Multi-agent Belief Revision System with a Geographical Information System (GIS). The inherent multidisciplinary features of the involved expertises in the field of environmental management, the need to define clear policies that allow the synthesis of divergent perspectives, its systematic application, and the reduction of the costs and time that result from this integration, are the main reasons that motivate the proposal of this project. This paper is organised in two parts: in the first part we present and discuss the developed Distributed Belief Revision Test-bed — DiBeRT; in the second part we analyse its application to the environmental decision support domain, with special emphasis on the interface with a GIS.

An Open Source BI Approach: Concept Proof Tracking Fleet

É possível assistir nos dias de hoje, a um processo tecnológico evolutivo acentuado por toda a parte do globo. No caso das empresas, quer as pequenas, médias ou de grandes dimensões, estão cada vez mais dependentes dos sistemas informatizados para realizar os seus processos de negócio, e consequentemente à geração de informação referente aos negócios e onde, muitas das vezes, os dados não têm qualquer relacionamento entre si. A maioria dos sistemas convencionais informáticos não são projetados para gerir e armazenar informações estratégicas, impossibilitando assim que esta sirva de apoio como recurso estratégico. Portanto, as decisões são tomadas com base na experiência dos administradores, quando poderiam serem baseadas em factos históricos armazenados pelos diversos sistemas. Genericamente, as organizações possuem muitos dados, mas na maioria dos casos extraem pouca informação, o que é um problema em termos de mercados competitivos. Como as organizações procuram evoluir e superar a concorrência nas tomadas de decisão, surge neste contexto o termo Business Intelligence(BI). A GisGeo Information Systems é uma empresa que desenvolve software baseado em SIG (sistemas de informação geográfica) recorrendo a uma filosofia de ferramentas open-source. O seu principal produto baseia-se na localização geográfica dos vários tipos de viaturas, na recolha de dados, e consequentemente a sua análise (quilómetros percorridos, duração de uma viagem entre dois pontos definidos, consumo de combustível, etc.). Neste âmbito surge o tema deste projeto que tem objetivo de dar uma perspetiva diferente aos dados existentes, cruzando os conceitos BI com o sistema implementado na empresa de acordo com a sua filosofia. Neste projeto são abordados alguns dos conceitos mais importantes adjacentes a BI como, por exemplo, modelo dimensional, data Warehouse, o processo ETL e OLAP, seguindo a metodologia de Ralph Kimball. São também estudadas algumas das principais ferramentas open-source existentes no mercado, assim como quais as suas vantagens/desvantagens relativamente entre elas. Em conclusão, é então apresentada a solução desenvolvida de acordo com os critérios enumerados pela empresa como prova de conceito da aplicabilidade da área Business Intelligence ao ramo de Sistemas de informação Geográfica (SIG), recorrendo a uma ferramenta open-source que suporte visualização dos dados através de dashboards.

Apoio à implementação do Sistema de Informação Territorial da Administração Interna e à análise de padrões espaciais

Este documento visa apresentar o trabalho de Estágio realizado na Direção Geral de Administração Interna (DGAI) como parte integrante e conclusiva do Mestrado em Gestão do Território na Área de Especialização em Deteção Remota e Sistemas de Informação Geográfica, ministrado pela Faculdade de Ciências Sociais e Humanas da Universidade Nova de Lisboa. O Estágio desenvolveu-se em duas fases. A primeira detém um caráter mais genérico e teve como objetivo prestar apoio à consolidação do Sistema de Informação Territorial da Administração Interna (SITAI), onde, entre diversas atividades desenvolvidas, a principal, e conforme exposto no presente relatório, reside na adaptação de dados do Instituto Nacional de Estatística (Censos 2011) ao território nacional após a Reorganização Administrativa do Território das Freguesias (RATF). A segunda enfoca o fenómeno da Violência Doméstica (VD) e consiste no tratamento e análise de vários tipos de dados provenientes da base de dados do Ministério da Administração Interna (MAI) relacionados com o mesmo. Não obstante esta segmentação de trabalhos, é objetivo deste Estágio a aplicação dos Sistemas de Informação Geográfica (SIG) envolvendo dados de realidades específicas e a produção de informação capaz de se constituir como instrumento de suporte à decisão e desenvolvimento de políticas de segurança interna pelas quais o MAI é responsável.

Using GPS, GIS & remote sensing to understand Niagara Terroir : Pinot noir in the Four Mile Creek & St. David's Bench sub-appellations

The relationships between vine water status, soil texture, and vine size were observed in four Niagara, Ontario Pinot noir vineyards in 2008 and 2009. The vineyards were divided into water status zones using geographic information systems (GIS) software to map the seasonal mean midday leaf water potential (,P), and dormant pruning shoot weights following the 2008 season. Fruit was harvested from all sentinel vines, bulked by water status zones and made into wine. Sensory analysis included a multidimensional sorting (MDS) task and descriptive analysis (DA) of the 2008 wines. Airborne multispectral images, with a spatial resolution of 38 cm, were captured four times in 2008 and three times in 2009, with the final flights around veraison. A semi-automatic process was developed to extract NDVI from the images, and a masking procedure was identified to create a vine-only NDVI image. 2008 and 2009 were cooler and wetter than mean years, and the range of water status zones was narrow. Yield per vine, vine size, anthocyanins and phenols were the least consistent variables. Divided by water status or vine size, there were no variables with differences between zones in all four vineyards in either year. Wines were not different between water status zones in any chemical analysis, and HPLC revealed that there were no differences in individual anthocyanins or phenolic compounds between water status zones within the vineyard sites. There were some notable correlations between vineyard and grape composition variables, and spatial trends were observed to be qualitatively related for many of the variables. The MDS task revealed that wines from each vineyard were more affected by random fermentation effects than water status effects. This was confirmed by the DA; there were no differences between wines from the water status zones within vineyard sites for any attribute. Remotely sensed NDVI (normalized difference vegetation index) correlated reasonably well with a number of grape composition variables, as well as soil type. Resampling to a lower spatial resolution did not appreciably affect the strength of correlations, and corresponded to the information contained in the masked images, while maintaining the range of values of NDVI. This study showed that in cool climates, there is the potential for using precision viticulture techniques to understand the variability in vineyards, but the variable weather presents a challenge for understanding the driving forces of that variability.

Using GPS, GIS & remote sensing to understand Niagara Terroir

The focus of this study was to detennine whether soil texture and composition variables were related to vine water status and both yield components and grape composition, and whether multispectral high definition airborne imagery could be used to segregate zones in vineyards to target fruit of highest quality for premium winemaking. The study took place on a 10-ha commercial Riesling vineyard at Thirty Bench Winemakers, in Beamsville (Ontario). Results showed that Soil moisture and leaf'l' were temporally stable and related to berry composition and remotely-sensed data. Remote-sensing, through the calculation of vegetation indices, was particularly useful to predict vine vigor, yield, fruit maturity as well as berry monoterpene concentration; it could also clearly assist in making wines that are more representative ofthe cultivar used, and also wines that are a reflection of a specific terroir, since calculated vegetation indices were highly correlated to typical Riesling.

Étude du rôle des professionnels de l'information dans les systèmes d'information Web du Gouvernement fédéral canadien

Les professionnels de l'information traversent actuellement une période de redéfinition de leur profession provoquée par la transformation de l'information et des processus informationnels vers un mode de plus en plus électronique. Les systèmes d'information Web (SIW) — c'est-à-dire des systèmes d'information basés sur les technologies Web tels que les sites Web externes, les intranets, les systèmes de commerce électronique et les extranets — font partie des technologies à l'origine de ces changements. Ces systèmes sont de plus en plus adoptés par les organisations et, en particulier, par les gouvernements dans leur volonté de devenir électroniques. Le gouvernement fédéral canadien est reconnu comme un des plus innovateurs en matière de SIW et doit adapter son environnement informationnel, dont font partie les professionnels de l'information, à l'introduction de ces systèmes. Malgré l'innovation que les SIW représentent, peu d'études empiriques ont été menées pour identifier quels sont les intervenants nécessaires à leur mise en place. Aucun consensus n'émerge de la littérature quant à la nature de l'intervention des professionnels de l'information dans ces systèmes. Cette recherche vise à accroître les connaissances sur l'intervention des professionnels de l'information dans les SIW. Pour les besoins de cette recherche, les professionnels de l'information sont définis comme les personnes ayant une maîtrise en bibliothéconomie et sciences de l'information ou toute autre formulation équivalente. Cette recherche étudie quatre questions de recherche qui portent sur : (1) les rôles des professionnels de l'information décrits dans les politiques d'information pan-gouvernementales liées aux SIW ainsi que ceux des autres intervenants mentionnés en lien direct avec les SIW, (2) les types de SIW dans lesquels les professionnels de l'information interviennent, (3) les tâches des professionnels de l'information dans ces SIW, et (4) les autres intervenants qui travaillent dans ces systèmes. Une approche qualitative a été utilisée pour répondre à ces questions et implique quatre modes de collecte des données : (1) des entrevues en profondeur en personne avec des professionnels de l'information impliqués dans des SIW, (2) une analyse des SIW où interviennent ces professionnels de l'information, (3) une analyse des politiques pan-gouvernementales liées aux SIW, et (4) la documentation pertinente. Les professionnels de l'information rencontrés proviennent de sept ministères du gouvernement fédéral canadien, ministères retenus pour leur implication dans les SIW. Les résultats indiquent que les professionnels de l'information rencontrés interviennent dans les SIW aux niveaux micro et macro, c'est-à-dire dans des SIW spécifiques ainsi que globalement au niveau de l'ensemble des SIW d'un ministère ou du gouvernement fédéral. Ces professionnels de l'information sont impliqués dans toutes les dimensions et les phases de développement des SIW. Les tâches liées au contenu sont prédominantes mais les tâches technologiques sont aussi très présentes. Trois variables se dégagent de cette étude qui ont un impact sur l'intervention des professionnels de l'information dans les SIW : les types de SIW, les types de postes occupés par les professionnels de l'information et les types de gouvernance.
