Acoustic performance of vegetation and soil substratum in an urban context

The management of an urban context in a Smart City perspective requires the development of innovative projects, with new applications in multidisciplinary research areas. They can be related to many aspects of city life and urban management: fuel consumption monitoring, energy efficiency issues, environment, social organization, traffic, urban transformations, etc. Geomatics, the modern discipline of gathering, storing, processing, and delivering digital spatially referenced information, can play a fundamental role in many of these areas, providing new efficient and productive methods for a precise mapping of different phenomena by traditional cartographic representation or by new methods of data visualization and manipulation (e.g. three-dimensional modelling, data fusion, etc.). The technologies involved are based on airborne or satellite remote sensing (in visible, near infrared, thermal bands), laser scanning, digital photogrammetry, satellite positioning and, first of all, appropriate sensor integration (online or offline). The aim of this work is to present and analyse some new opportunities offered by Geomatics technologies for a Smart City management, with a specific interest towards the energy sector related to buildings. Reducing consumption and CO2 emissions is a primary objective to be pursued for a sustainable development and, in this direction, an accurate knowledge of energy consumptions and waste for heating of single houses, blocks or districts is needed. A synoptic information regarding a city or a portion of a city can be acquired through sensors on board of airplanes or satellite platforms, operating in the thermal band. A problem to be investigated at the scale A problem to be investigated at the scale of the whole urban context is the Urban Heat Island (UHI), a phenomenon known and studied in the last decades. UHI is related not only to sensible heat released by anthropic activities, but also to land use variations and evapotranspiration reduction. The availability of thermal satellite sensors is fundamental to carry out multi-temporal studies in order to evaluate the dynamic behaviour of the UHI for a city. Working with a greater detail, districts or single buildings can be analysed by specifically designed airborne surveys. The activity has been recently carried out in the EnergyCity project, developed in the framework of the Central Europe programme established by UE. As demonstrated by the project, such data can be successfully integrated in a GIS storing all relevant data about buildings and energy supply, in order to create a powerful geospatial database for a Decision Support System assisting to reduce energy losses and CO2 emissions. Today, aerial thermal mapping could be furthermore integrated by terrestrial 3D surveys realized with Mobile Mapping Systems through multisensor platforms comprising thermal camera/s, laser scanning, GPS, inertial systems, etc. In this way the product can be a true 3D thermal model with good geometric properties, enlarging the possibilities in respect to conventional qualitative 2D images with simple colour palettes. Finally, some applications in the energy sector could benefit from the availability of a true 3D City Model, where the buildings are carefully described through three-dimensional elements. The processing of airborne LiDAR datasets for automated and semi-automated extraction of 3D buildings can provide such new generation of 3D city models.

This text is a hermeneutic exercise about one of the paradigmatic works of Vinicius de Moraes, Orfeu da Conceição. This plays opens a partnership between the poet and the composer Antonio Carlos Jobim, which was fruitful and unique for Brazilian arts. Orfeu da Conceição is also paradigmatic because it is the first work to bring black actors to the stages of the Municipal Theater of Rio de Janeiro. Orfeu da Conceição led to one of the films that most contributed, positively or negatively, to the international image of Brazil in the second half of the 20th century, the award-winning Orpheus Negro, by Marcel Camus. The text will notice how many of the ideas and representations of the favela were already visible in the Brazilian popular repertoire prior to the composition of the play. The idea, in general, is to observe how, in addition to its poetic-musical quality, Orfeu da Conceição can also serve as a reflection on how we represent and see favelas in the urban context, both in 1956 and today.

Tal (mount) Irbid in Irbid city, Jordan, with its continuous human occupation from the Bronze Age until the present, demonstrates the main landmark that has guided the spread of the urban growth of the city. The outcome of studies carried out at Irbid’s historic core, in relation to assessing the loss and degradation of the core’s cultural heritage, shall be analyzed, investigated, and discussed, as also concerns, obstacles, and issues of sustainability to this urban heritage conservation and tourism planning. The paper starts by defining the urban heritage for the historic core, which tends to be set aside, in the city’s rapid development. Actually, the remaining historic buildings can also provide the necessary inter-relationships between the historic core areas and the wider urban context to achieve a sustainable and integrated tourism and conservation action plan for the three heritage neighborhoods around the Tal, while building on tourism opportunities and taking into consideration the needs and the vital role of the local community. The paper concludes that urban heritage conservation and protection of the integrity and identity of the historic core city fabric can assist in its branding, promotion, and management in ways that could enhance the local community belonging, quality of everyday lifestyle, and visitors' experience.
