Geo-visual analytics for urban design in the context of future Internet

The internet, where much of the information has reference to location, together with the latest generation of geographical web services, represent a very large information space that can be used for planning and design. The wealth of information accessible, which requires new forms of interaction and management of the data available, has brought in recent year to the growth of the domain of visual analytics. In addition, the availability of 3D geobrowsers provides the technological means for interactive 3D environments which can be used to access large-scale geographical information. This technological scenario is paving the way to 3D webbased, geo-visual analytics tools for land planning and urban design tools. This paper illustrates the results of a research effort which has brought to the development of an interactive geo-visual analytics platform for land planning and urban design which makes use of procedural modelling algorithms

Paracetamol and antibiotics in childhood and subsequent development of wheezing/asthma: association or causation?

Several studies found an association between early administration of paracetamol and antibiotics and development of wheezing. This could be due to confounding: wheeze and asthmatic symptoms in early childhood are difficult to distinguish from respiratory tract infections that are widely treated with these drugs; in case of persistence of symptoms up to school age, this could explain the observed relationship

Development of an ELISA test for Salmonella serological monitoring in Brazil

EMBRAPA/CNPSA developed an ELISA test based on LPS antigens from Salmonella Typhimurium. After the optimal dilution determination of the test components, four sera were chosen as controls. The interplate variation was controlled by a coefficient correlation between standard and daily curves of control sera and the coefficient variation of sample sera triplicates. The cut-off was determined by a dispersion analysis in a nursery piglet population proved to be salmonellae negative. The test performance was evaluated in experimentally and naturally S. Typhimurium infected pigs and in animals vaccinated with other Salmonella serovars. The seroconversion was observed after two weeks post inoculation in experimentally infected and vaccinated animals. In naturally infected animals, which were sampled twice during the finishing period, at the first sampling 75 % of pigs were eliminating salmonellae in feces and 25 % were positive in the ELISA. At the second sampling 76.9 % became serologically positive. These results suggest that the developed test can be used for Salmonella Typhimurium monitoring programs in swine

GEOSPATIAL DATA PROCESSING FOR 3D CITY MODEL GENERATION, MANAGEMENT AND VISUALIZATION

Recent developments of 3D technologies and tools have increased availability and relevance of 3D data (from 3D points to complete city models) in the geospatial and geo-information domains. Nevertheless, the potential of 3D data is still underexploited and mainly confined to visualization purposes. Therefore, the major challenge today is to create automatic procedures that make best use of available technologies and data for the benefits and needs of public administrations (PA) and national mapping agencies (NMA) involved in “smart city” applications. The paper aims to demonstrate a step forward in this process by presenting the results of the SENECA project (Smart and SustaiNablE City from Above – http://seneca.fbk.eu). State-of-the-art processing solutions are investigated in order to (i) efficiently exploit the photogrammetric workflow (aerial triangulation and dense image matching), (ii) derive topologically and geometrically accurate 3D geo-objects (i.e. building models) at various levels of detail and (iii) link geometries with non-spatial information within a 3D geo-database management system accessible via web-based client. The developed methodology is tested on two case studies, i.e. the cities of Trento (Italy) and Graz (Austria). Both spatial (i.e. nadir and oblique imagery) and non-spatial (i.e. cadastral information and building energy consumptions) data are collected and used as input for the project workflow, starting from 3D geometry capture and modelling in urban scenarios to geometry enrichment and management within a dedicated webGIS platform
