Cunha, Jácome, João Paulo Fernandes, Pedro Martins, Rui Pereira, and João Saraiva. "Refactoring meets Model-Driven Spreadsheet Evolution." Proceedings of the 9th International Conference on the Quality of Information and Communications Technology, Quality in Model Driven Engineering Track. 2014. 196-201. Abstractquatic14.pdf

Software refactoring is a well-known technique that provides transformations on software artifacts with the aim of improving their overall quality. In this paper we present a set of refactorings for ClassSheets, a modeling language that allows to specify the business logic of a spreadsheet in an object-oriented fashion. The set of refactorings that we propose allows us to improve the quality of these spreadsheet models. Moreover, it is implemented in a setting that guarantees that all model refactorings are automatically carried to all the corresponding (spreadsheet) instances, thus providing an automatic evolution of the data so it is always synchronized with the model.

Ramos, Tania, Maria Isabel Gomes, and Ana Paula Barbosa-povoa. "Recyclable packaging waste collection systems: redesigning service areas and collection routes in a real case-study." 2nd International Conference WASTES: Solutions, Treatments and Opportunities. Braga, Portugal 2013. Abstract2013_ramosgomesbpovoa_wastes2013.pdf

This paper addresses the planning of a real recyclable packaging waste collection system operating in Portugal. The company’s logistics network is characterized by the existence of multiple depots and multiple products to be collected in each site. Service areas and vehicle routes are currently defined respecting the municipal boundaries and present a need for improvement. To study this problem mixed integer linear programming formulations have been developed allowing the redesign of service areas and of collection routes under two scenarios, respectively, considering the definition of service areas by depot and by material. The scenario where the current service areas are maintained and the collection routes are optimized is also studied. Savings up to 20% in total distance are achieved by redesigning service areas and collection routes.

Os serviços Web são frequentemente suportados por sistemas com uma arquitetura em camadas, sendo utilizadas bases de dados relacionais para armazenamento dos dados. A replicação dos diversos componentes tem sido uma das formas utilizadas para obter melhorarias de escalabilidade destes serviços. Adicionalmente, a utilização de bases de dados em memória permite alcançar um desempenho mais elevado. No entanto é conhecida a fraca escalabilidade das bases de dados com o número de núcleos em máquinas multi-núcleo. Neste artigo propomos uma nova abordagem para lidar com este problema, intitulada MacroDDB. Utilizando uma solução de replicação hierárquica, a nossa proposta, replica a base da dados em vários nós, sendo que cada nó, por sua vez, executa um conjunto de réplicas da base de dados. Esta abordagem permite assim lidar com a falta de escalabilidade das bases de dados relacionais em máquinas multi-núcleo, o que por sua vez melhora a escalabilidade geral dos serviços.
