Creating and Governing Cultural Heritage in the European Union
2020
Creating and Governing Cultural Heritage in the European Union: The European Heritage Label provides an interdisciplinary examination of the ways in which European cultural heritage is created, communicated, and governed via the new European Heritage Label scheme. Drawing on ethnographic field research conducted across ten countries at sites that have been awarded with the European Heritage Label, the authors of the book approach heritage as an entangled social, spatial, temporal, discursive, narrative, performative, and embodied process. Recognising that heritage is inherently political and used by diverse actors as a tool for re-imagining communities, identities, and borders, and for gene…
Exploiting Data Analytics and Deep Learning Systems to Support Pavement Maintenance Decisions
2021
Road networks are critical infrastructures within any region and it is imperative to maintain their conditions for safe and effective movement of goods and services. Road Management, therefore, plays a key role to ensure consistent efficient operation. However, significant resources are required to perform necessary maintenance activities to achieve and maintain high levels of service. Pavement maintenance can typically be very expensive and decisions are needed concerning planning and prioritizing interventions. Data are key towards enabling adequate maintenance planning but in many instances, there is limited available information especially in small or under-resourced urban road authorit…
Using fractal dimensions for characterizing intra-urban diversity : the example of Brussels
2003
International audience; The objective of this paper is to compare fractal-based parameters calculated by different fractal methods for urban built-up areas and to link the observed spatial variations to variables commonly used in urban geography, urban economics, or land-use planning. Computations are performed on Brussels, Belgium. Two fractal methods (correlation and dilation) are systematically applied for evaluating the fractal dimension of built-up surfaces; correlation is used to evaluate the fractal dimension of the borders (lines). Analyses show that while fractal dimension is ideal for distinguishing the morphology of Brussels, each estimation technique leads to slightly different …
Les défis de la gouvernance urbaine à Manille
2014
La région capitale des Philippines est une des plus grandes aires urbaines du monde en termes de population. Le périmètre officiel du Grand Manille (17 municipalités) abrite environ 12 millions d’habitants et l’expansion périmétropolitaine porte le chiffre réel de Manille à 15 ou 16 millions d’habitants.La rapide croissance de l’aire urbaine depuis les années 1960 a conduit à de gros problèmes de gestion du logement, de la circulation, des déchets et des risques d’inondation, entre autres. Les phénomènes sont interdépendants.Créée sous Ferdinand Marcos, la National Capital Region fut gérée par son épouse Imelda Marcos, gouverneure du Grand Manille. Après la chute de la dictature, une volont…
Environmental mitigation hierarchy and biodiversity offsets revisited through habitat connectivity modelling.
2020
International audience; Biodiversity loss is accelerating because of unceasing human activity and land clearing for development projects (urbanisation, transport infrastructure, mining and quarrying …). Environmental policy-makers and managers in different countries worldwide have proposed the mitigation hierarchy to ensure the goal of “no net loss (NNL) of biodiversity” and have included this principle in environmental impact assessment processes. However, spatial configuration is hardly ever taken into account in the mitigation hierarchy even though it would greatly benefit from recent developments in habitat connectivity modelling incorporating landscape graphs. Meanwhile, national, Euro…
Energy Management and Smart Grids
2013
The paper outlines energy management concepts and the smart grid evolution. The necessity of considering energy management as a crucial innovation in load supplying to permit a more powerful penetration of renewable energy usage at the building and city level and to perform energy savings and CO2 emissions reduction is pointed out. The driving factors to enhance the current power distribution are presented, and the benefits concerning smart grids are underlined. In the paper, a specific energy management analysis is reported by considering all the electric value chain, and the demand-side management and distributed on site control actions are described. To verify the benefit of energy manag…
Aqueous-phase reactive species formed by fine particulate matter from remote forests and polluted urban air
2021
In the aqueous phase, fine particulate matter can form reactive species (RS) that influence the aging, properties, and health effects of atmospheric aerosols. In this study, we explore the RS yields of aerosol samples from a remote forest (Hyytiälä, Finland) and polluted urban locations (Mainz, Germany; Beijing, China), and we relate the RS yields to different chemical constituents and reaction mechanisms. Ultra-high-resolution mass spectrometry was used to characterize organic aerosol composition, electron paramagnetic resonance (EPR) spectroscopy with a spin-trapping technique was applied to determine the concentrations of ⚫OH, O2⚫-, and carbon- or oxygen-centered organic radicals, and a …
Analysis of the performance of the TES algorithm over urban areas
2014
International audience; The temperature and emissivity separation (TES) algorithm is used to retrieve the land surface emissivity (LSE) and land surface temperature (LST) values from multispectral thermal infrared sensors. In this paper, we analyze the performance of this methodology over urban areas, which are characterized by a large number of different surface materials, a variability in the lowest layer of the atmospheric profiles, and a 3-D structure. These specificities induce errors in the LSE and LST retrieval, which should be quantified. With this aim, the efficiency of the TES algorithm over urban materials, the atmospheric correction, and the impact of the 3-D architecture of urb…
CHIMERA: A BIM+GIS SYSTEM FOR CULTURAL HERITAGE
2020
Abstract. In the last years, many researches are conducted on systems for Cultural Heritage, trying to adapt BIM systems to CH needs; furthermore, the interest around the integration of BIM systems and GIS systems spreads. Chimera, presented in this paper, is the final product of about 8 years of research on this broad topic and has been specifically conceived for the realm of CH. It joins the small group of ready-to work information systems that allow the concurrently use of different integrated data, as 3D models, point clouds but also 2D maps or images. It also presents different functionalities that allow to work at a multiscale approach, including switching from a “single object level”…
The effect of residential urban greenness on allergic respiratory diseases in youth: A narrative review
2020
Abstract Background Environmental exposures across the life course may be a contributor to the increased worldwide prevalence of respiratory and allergic diseases occurring in the last decades. Asthma and rhinoconjunctivitis especially contribute to the global burden of disease. Greenness has been suggested to have beneficial effects in terms of reduction of occurrence of allergic respiratory diseases. However, the available evidence of a relationship between urban greenness and childhood health outcomes is not yet conclusive. The current review aimed at investigating the current state of evidence, exploring the relationship between children's exposure to residential urban greenness and dev…
