Megacities, with their large and complex infrastructures, are significant sources of methane emissions. To develop a simple, low-cost methodology to quantify these globally important sources, this study focuses on mobile measurements (CH4) its isotopic composition in Paris. Data collected between September 2018 March 2019 resulted 17 days measurements, which provided spatial distribution street...

One of the vehicle subsystem where large advantage is expected in lightweight design is the bumper subsystems. Bumper subsystems are designed to prevent or reduce physical damage to the front or rear ends of passenger motor vehicles during collusion. In this paper, detail design aspects and method of analysis with particular reference to the application of composite materials to automotive fron...

Urban models can be collected area covering and efficiently based on aerial data like stereo images or LIDAR. While a large number of applications like simulations are already feasible based on the available three-dimensional building representations, a further quality improvement is required for some other tasks. Especially, if very realistic visualisations from pedestrian viewpoints have to b...

We developed a ground truth database for urban areas from the Global Rural-Urban Mapping Project (GRUMP) Settlement Points gazetteer of populated place names by visually interpreting 3,734 urban points on satellite images, thus acquiring 2,144 urban and 1,388 non-urban data points. Our database contained many more urban data points than the existing databases, which had only 0 to 11 ground trut...
