Roadway bridges, being one of the most critical road infrastructures components, require regular maintenance actions. Therefore, it becomes important to define strategies to maximize societal benefits, derived from the investment made in these assets. Consequently, this investment should be planned, effectively managed and technically supported by appropriate management systems, supported in quality control plans. For this purpose, authorities need to produce an asset management plan which should, not only define the goals to be achieved by exploiting the roadway bridge network, but also identify the investment needs and priorities based on a life cycle cost criteria. Additionally, a proper condition assessment of these assets must be conducted to support the decision-making process regarding their preservation. A COST Action recently started in Europe with the aim of standardizing the establishment of quality control plans for roadway bridges. This paper describes this Action and, particularly, its most recent developments.
RESUMOA Internet das Coisas (IoT) é uma rede de coisas físicas e aparelhos virtuais que se comunicam e interagem entre si. O desenvolvimento de produtos IoT tem se mostrado um desafio, pois demanda times multidisciplinares para lidar com hardware, software e integração entre eles, bem como requisitos complexos impostos pela heterogeneidade de plataformas e a segurança de dados, entre outras questões. Neste contexto, nosso trabalho investiga o desenvolvimento de produtos IoT e suas especificidades. Neste artigo apresentamos um produto IoT para monitoramento e controle de reservatórios de água. Os dados coletados ao longo do desenvolvimento deste produto serão utilizados futuramente para especificação de um processo de desenvolvimento de produtos IoT que deverá auxiliar desenvolvedores. O produto foi implementado em uma casa fictícia, em escala reduzida e experimental, e apresentou resultados satisfatórios quanto ao monitoramento e controle das caixas d'água realizadas à distância através de uma aplicação web.
Student evaluation criteria is a non-trivial variation point in a Student Information System software product line. It can vary significantly in different institutions, or even in different areas of a specific institution, and also over time. This paper presents a highly flexible model-driven development solution to incorporate and change one or many different evaluation criteria in each specific product of the line, where a domain expert should be able to model each set of student evaluation criteria, and automatically transform it into software code, without involvement of software engineers. For this purpose, we created a domain-specific modeling language DSCHOLAR and a model-tocode transformation dscholar2Code to model and automatically implement such a software component. They were both validated using a case study and proof of concept, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
