Enabling SmartWorkflows over heterogeneous ID-sensing technologies

Sensing technologies in mobile devices play a key role in reducing the gapbetween the physical and the digital world. The use of automatic identification capabilitiescan improve user participation in business processes where physical elements are involved(Smart Workflows). However, identifying all objects in the user surroundings does notautomatically translate into meaningful services to the user. This work introduces Parkour,an architecture that allows the development of services that match the goals of each ofthe participants in a smart workflow. Parkour is based on a pluggable architecture thatcan be extended to provide support for new tasks and technologies. In order to facilitatethe development of these plug-ins, tools that automate the development process are alsoprovided. Several Parkour-based systems have been developed in order to validate theapplicability of the proposal

Swells, soundings, and sustainability, but... here be monsters

The Roger Revelle Commemorative Lecture Series was created by the Ocean Studies Board of the National Academies in honor of Roger Revelle to highlight the important links between ocean sciences and public policy. Dawn J. Wright, the eighteenth annual lecturer, spoke on April 28, 2017, at the Smithsonian National Museum of Natural History. ABSTRACT. We have been mapping the ocean for hundreds of years, from the stick charts of the ancient Marshall Islanders, to the initial soundings of the nineteenth-century Challenger expedition, to the multibeam sonars and robots of modern surveys. Today we map the ocean not only to increase fundamental scienti c understanding of the ocean system but also to protect life and property, promote economic vitality, and inform ecosystem-based management and policy. Toward this end, the United Nations Sustainable Development Goals provide an overarching context for modern map development, drawing upon a vast wealth of maps and mapping experience that couples appropriate data with spatial analyses. At the same time, there is an overarching need for more compelling map design to help e ectively communicate results and future predictions across a wide variety of research areas. Indeed, modern-day mapping systems have become increasingly “intelligent,” and these “smart maps” are changing what we measure, how we analyze and evaluate systems, how we forecast, and even how we develop new regulations. Intelligent maps are addressing myriad challenges, from the tracking of marine debris and marine mammals, to “geodesigning” the ocean to support multiple uses (commercial shing, recreation, alternative energy, transportation, conservation), to creating scienti c cyberinfrastructures for ocean observatories. Yet “there be monsters”—the major research challenges that continue to confound us. Despite the growing intelligence of mapping systems, we must cope with both the overabundance and the paucity of ocean data (i.e., “big data” and “dark data”), data multidimensionality, the need to increase data resiliency, and the ability to make data more accessible to many audiences. How do we address these major issues to create open and e ective access to ocean science that will contribute to the global public good and ultimately to the sustainability of Planet Ocean

Uma arquitetura de serviços web como meio de intercâmbio de dados entre sistemas heterôgeneos

TCC (graduação) - Universidade Federal de Santa Catarina, Campus Araranguá, Curso de Tecnologias da Informação e Comunicação.No contexto tecnológico atual, tecnologias emergem cotidianamente e com elas a necessidade de integração visando proporcionar uma maior flexibilidade em qualquer campo atendido por um dado conjunto tecnológico distinto. No âmbito de negócios, informações são consideradas um bem vital para a organização. Por este fato, a centralização das mesmas agiliza e facilita a tomada de decisão, bem como a execução de qualquer processo inerente ao negócio. Diferente do modelo lógico empresarial, onde todas as informações dos diversos setores que compõe a organização são centralizadas, no modelo físico, tais informações estão dispostas em vários sistemas, dispositivos, bases de dados, e outros recursos computacionais, empregando diferentes tecnologias. Com o propósito de interligar de modo transparentes estes componentes heterogêneos surge a necessidade de um meio capaz de atingir tal objetivo. É neste contexto que se torna relevante o emprego da tecnologia de serviços web. A arquitetura de serviços web está em expansão, e tem grande aceitabilidade no meio tecnológico, por proporcionar uma interface padronizada, possibilitando a comunicação entre diferentes plataformas com uma curva de adaptação reduzida. Propõe-se aqui uma arquitetura de software que implementa uma interface de serviços web para promover o intercâmbio de dados entre dispositivos móveis e um sistema ERP. Empregando conceitos de serialização de objetos, protocolo de transporte e servidores de aplicação, a solução tem o propósito de promover a comunicação entre as duas plataformas de modo transparente para os usuários. Busca-se ainda um desempenho satisfatório dentro das restrições de redes móveis e poder de processamento desses dispositivos. A aplicação da arquitetura proposta proporcionou um aumento no desempenho das equipes de vendas a qual utilizam os dispositivos móveis. Em virtude da precariedade das redes móveis, na solução atual, uma simples transferência de um pedido de compras para o sistema ERP da empresa vinculada ao estudo de caso era mensurada em minutos. Com a solução de serviços web, foi possível a redução desta unidade para segundos.In the current technological environment new technologies emerge daily and with them the need for integration. It provides flexibility in any field supported by a particular set technological. Within business, information is considered a vital asset to the organization. Thus, the centralization of it speeds up and facilitates the decision-making and the execution of any process inherent to the business. Unlike the logical business model, where all the information from various sectors that make up the organization are centralized, in the physical model such information is arranged in various systems, devices, databases, and other computer resources by using different technologies. In order to interconnect in a transparent these heterogeneous components, it is proposed a solution using web services. The web service architecture is in expansion and has great acceptability by providing a standardized interface and by enabling communication among different platforms with a reduced adaptation curve. In this work is proposed a software architecture that implements a web services interface in order to promote the exchange of data between mobile devices and an ERP system. Employing concepts of object serialization, transport protocol and application servers, the solution is designed to promote transparently the communication between the two platforms. Also, is still intended to get satisfactory performance within the constraints of mobile networks and processing power of today's mobile devices when compared to the solution previously adopted. Once applied the proposed architecture we observed an increase in performance of the sales teams which use mobile devices. Given the precarious nature of mobile networks in the current solution a simple transfer of a purchase order for the company’s ERP system was measured in minutes. With the web services solution it was possible to reduce this unit to seconds
