Along with the strong movement towards sustainable urban environments, there is an increasing use of green roof systems, including the semi-extensive green roofs, which are composed of lightweight layers of freedraining material that support low-growing, tough, and drought-resistant vegetation. Various kinds of green roof systems are also used at street levels, on the top of underground car par...
Absolute positioning of vehicles is based on Global Navigation Satellite Systems (GNSS) combined with on-board sensors and high-resolution maps. In Cooperative Intelligent Transportation Systems (C-ITS), the positioning performance can be augmented by means of vehicular networks that enable vehicles to share location-related information. This paper presents an Implicit Cooperative Positioning (...
We have adopted a numerical method from computational fluid dynamics, the Lattice Boltzmann Method (LBM), for real-time simulation and visualization of flow and amorphous phenomena, such as clouds, smoke, fire, haze, dust, radioactive plumes, and air-borne biological or chemical agents. Unlike other approaches, LBM discretizes the micro-physics of local interactions and can handle very complex ...
Influence of the geometrical parameters of urban canyons on the convective heat transfer coefficient
Abstract In this paper, a three-dimensional vision-aided method is proposed to improve global navigation satellite system (GNSS) real-time kinematic (RTK) positioning. To mitigate the impact of reflected non-line-of-sight (NLOS) reception, sky-pointing camera with deep neural network was employed exclude these measurements. However, NLOS exclusion results in distorted geometry. fill ga...
In this work we numerically investigate the flow conditions inside uniform and non-uniform street canyons well within atmospheric boundary layer. The numerical simulations use steady RANS method with near-wall modelling approach to simulate wall roughness at boundary. With aim of investigating both structure in broad terms, pedestrian comfort canyon between parallel buildings, test different co...
