Assessment of influential operational parameters in the mitigation of CO2 emiss...
Balanuta, Vítor; Baptista, Patricia; Neves da Fonseca Cardoso Carreira, Fernando Paulo; Duarte, Gonçalo; Casaca, Cláudia Sofia Séneca da LuzThe European decarbonization goals and requirement for energy independence are mostly relying on intermittent renewable energy sources for electrification. A numerical model was developed to simulate the operation of a steam generator, allowing a study of the potential impacts of retrofitting existing coal-fired power plants to operate with biomass or coal–biomass mixtures on combustion parameters and CO2 emiss...

A dataset of acoustic measurements from soundscapes collected worldwide during ...
Challéat, Samuel; Farrugia, Nicolas; Froidevaux, Jérémy S. P.; Gasc, Amandine; Pajusco, Nicolas; Abrahams, Carlos R.; Acevedo-Charry, OrlandoPolitical responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions o...
Photovoltaic integrated electric vehicles: assessment of synergies between sola...
Sagaria, Shemin; Duarte, Gonçalo; Neves, Diana; Baptista, PatríciaElectric vehicles are promoting sustainable developments in the automotive industry. But the short driving range has been an inconvenience to the electric vehicle (EV) users. This paper evaluates the potential of Photovoltaic integrated into EV in real-world conditions to assess energy consumption, range and EV's charging frequency for battery and fuel cell powertrain configurations. A simulation model is devel...
Systematic method for developing reference driving cycles appropriate to electr...
Watling, David; Baptista, Patrícia; Duarte, Gonçalo; Gao, Jianbing; Chen, HaiboIncreasingly, demanding environmental standards reflect the need for improved energy efficiency and reduced externalities in the transportation sector. Reference driving cycles provide standard speed profiles against which future developments and innovations may be tested. In the paper, we develop such profiles for a class of electric L-category vehicles, which are anticipated to play an increasing future role ...
Including engine data for energy and pollutants assessment into the vehicle spe...
Mera, Zamir; Varella, Roberto; Baptista, Patrícia; Duarte, Gonçalo; Rosero Obando, FredyVehicle emission models are relevant for evaluating the performance of vehicle technologies and help in the definition of environmental policies. This paper presents an improved emissions modelling approach (named VSP+M) by combining the vehicle specific power (VSP) with load-regime engine maps for each VSP mode. The new modelling enabled to link tailpipe emissions to vehicle and engine operating conditions, ob...
Can EEG Be Adopted as a Neuroscience Reference for Assessing Software Programme...
Medeiros, Júlio; Couceiro, Ricardo; Duarte, Gonçalo; Durães, João; Castelhano, João; Duarte, Catarina; Castelo-Branco, Miguel; Madeira, HenriqueAn emergent research area in software engineering and software reliability is the use of wearable biosensors to monitor the cognitive state of software developers during software development tasks. The goal is to gather physiologic manifestations that can be linked to error-prone scenarios related to programmers' cognitive states. In this paper we investigate whether electroencephalography (EEG) can be applied ...
Assessment of wireless charging impacts based on real-world driving patterns: C...
Duarte, Gonçalo; Silva, André; Baptista, PatríciaIn the current transition to a smarter and more efficient transportation system, battery electric vehicle mileage and the time required for charging are still two main constraints that need to be overcome to enable a larger penetration of electric vehicles. Moreover, the few charging stations available are a consequence of the "supply and demand" problem. Consequently, wireless dynamic recharging can be a compl...

Assessing the connectivity of riparian forests across a gradient of human distu...
Fonseca, André; Ugille, Jean-Philippe; Michez, Adrien; Rodríguez-González, Patricia Maria; Duarte, Gonçalo; Ferreira, Teresa; Fernandes, Maria RosárioThe connectivity of riparian forests can be used as a proxy for the capacity of riparian zones to provide ecological functions, goods and services. In this study, we aim to test the potential of the freely available Copernicus “Riparian Zones” dataset to characterize the connectivity of riparian forests located in two European bioclimatic regions—the Mediterranean and the Central Baltic hydroregions—when subjec...
