Assessing the societal impact of smart grids: Outcomes of a collaborative resea...
Ferreira, Paula; Rocha, Ana; Araujo, Madalena; Afonso, Joao L.; Antunes, Carlos Henggeler; Lopes, Marta A.R.; Osório, Gerardo J.; Catalão, João P.S.Assessing the societal contributions of research is not simple, especially for research projects that produce outputs with low technology readiness level. This paper analyses the potential societal impacts of research resulting in technologies with low maturity, but with the potential to be further developed in the long-term. It uses the case of the ESGRIDS (Enhancing Smart Grids for Sustainability) collaborati...
Methodology for knowledge extraction from mobility big data
Ferreira, João C.; Monteiro, Vitor; Afonso, José; Afonso, Joao L.The spread of mobile devices with several sensors, together with mobile communication, provides huge volumes of real-time data (big data) about users' mobility habits, which should be correctly analysed to extract useful knowledge. In our research we explore a data mining approach based on a Naive Bayes (NB) classifier applied to different sources of big data. To achieve this goal, we propose a methodology base...
Tracking users mobility patterns towards CO2 footprint
Ferreira, João C.; Monteiro, Vitor; Afonso, José; Afonso, Joao L.This research work is based on the development of a mobile application and associated central services for tracking users' movements in a city, identifying the transportation mode and routes performed. This passive tracking generates useful data about users' habits, which are then associated with the CO2 emission in the form of a mobility invoice, with the goal of enabling the users to understand their carbon f...
