Optimizing Fuel Consumption and Pollutant Emissions of a Spark Ignition Engine for Eco-driving Applications
2018
VPPC 2018, Vehicle Power and Propulsion Conference, Chicago, ETATS-UNIS, 27-/08/2018 - 30/08/2018; The transportation sector is a major contributor to both air pollution and greenhouse gas emissions. While optimizing fuel consumption reduces CO2 emissions, it can increase fuel-rich operation and cause higher HC and CO emissions. A simplified emissions model is thus introduced in order to account for the impact of air/fuel ratio on both the exhaust concentration of regulated pollutants and the catalyst efficiency. This model is used to solve the eco-driving problem with dynamic programming and a weighted objective function. An emission-centered and a consumption-centered scenario are compare…
Comparison of the environmental assessment of an identical office building with national methods
2019
The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The ?be2226? office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amou…
Soil Science Challenges in a New Era: A Transdisciplinary Overview of Relevant Topics
2020
Transdisciplinary approaches that provide holistic views are essential to properly understand soil processes and the importance of soil to society and will be crucial in the future to integrate distinct disciplines into soil studies. A myriad of challenges faces soil science at the beginning of the 2020s. The main aim of this overview is to assess past achievements and current challenges regarding soil threats such as ero-sion and soil contamination related to different United Nations sustainable development goals (SDGs) including (1) sustainable food production, (2) ensure healthy lives and reduce environmental risks (SDG3), (3) ensure water availability (SDG6), and (4) enhanced soil carbo…
Tourism planning and innovation: The Caribbean under the spotlight
2018
International audience; The importance of the islands working together toward a multicentre product for tourists has been highlighted asearly as the 1980s, and yet hardly anything has been done in that sense. Can cluster be considered as the wayforward for the sustainable development of the Caribbean? This question could be considered as the first step ofthe tourism planning process. Hierarchical method or linkage method that works by identifying entities thatmatch each other based on the investigator selection of similar attribute categories is the most suitable clusteringapproach for the Caribbean. Despite the fact that cluster appears as a potential solution for issues faced by someCarib…
A methodological approach to analyze the territorial appropriation of high-speed rail from interactions between actions and representations of local …
2019
International audience; Because it is difficult to separate the specific transport impact from other factors influencing economic and spatial development, the focus in research is increasingly on understanding the process by which territorial changes occur in order to explain how economic and social agents and local authorities have appropriated new transportation systems. This appropriation plays a crucial part in territorial dynamics. The diversity of economic and spatial changes produced by high-speed rail indicates the existence of multiple modes of appropriation which vary according to the location of stations, the mobilization of local stakeholders confronted with the transport operat…
Chronic burden of near-roadway traffic pollution in 10 European cities (APHEKOM network).
2013
AD; International audience; Recent epidemiological research suggests that near road traffic-related pollution may cause chronic disease, as well as exacerbate related pathologies, implying that the entire “chronic disease progression” should be attributed to air pollution, no matter what the proximate cause was. We estimated the burden of childhood asthma attributable to air pollution in 10 European cities by calculating the number of cases of 1) asthma caused by near road traffic-related pollution, and 2) acute asthma events related to urban air pollution levels. We then expanded our approach to include coronary heart diseases in adults.Derivation of attributable cases required combining c…
Quantifying the health impacts of outdoor air pollution: useful estimations for public health action
2013
According to WHO,1 health impact assessment (HIA) is A combination of procedures, methods and tools used to evaluate the potential health effects of a policy, programme or project. Using qualitative, quantitative and participatory techniques, HIA aims to produce recommendations that will help decision makers and other stakeholders make choices about alternatives and improvements to prevent disease/injury, and to actively promote health. The typical procedural steps in HIA include screening, scoping, assessment of health effects, recommending alternatives and mitigations, reporting and monitoring.2 Each step helps predict or foresee potential effects of policy decisions on a population's hea…
From Buildings' End of Life to Aggregate Recycling under a Circular Economic Perspective: A Comparative Life Cycle Assessment Case Study
2021
The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildin…
Gares exurbanisées et développement urbain : Le cas des gares TGV bourguignonnes
2009
Dès la mise en service de la ligne TGV Sud-Est, au début des années 80, la Bourgogne a bénéficié de la création de deux nouvelles gares TGV, aménagées en périphérie des pôles urbains du Creusot et de Mâcon. Malgré leurs fonctions réduites, ces nouvelles gares périurbaines ont suscité d’ambitieux projets d’aménagement. De nouvelles zones d’activités ont ainsi vu le jour à proximité de ces gares. Ces projets n’ont eu toutefois que des retombées limitées en matière d’implantation d’activités économiques. Since the opening of TGV south-east railway line at the beginning of the 80s Bourgogne has profited by construction of two new stations beyond the edge of Le Creusot and Mâcon. Despite their l…
Reactive species formed upon interaction of water with fine particulate matter from remote forest and polluted urban air
2020
Interaction of water with fine particulate matter leads to the formation of reactive species (RS) that may influence the aging, properties, and health effects of atmospheric aerosols. In this study, we explore the RS yields of fine PM from remote forest (Hyytiälä, Finland) and polluted urban air (Mainz, Germany and Beijing, China) and relate these yields to different chemical constituents and reaction mechanisms. Ultrahigh-resolution mass spectrometry was used to characterize organic aerosol composition, electron paramagnetic resonance (EPR) spectroscopy with a spin-trapping technique was used to determine the concentrations •OH, O2•−, and carbon- or oxygen-centered organic radicals, …
