Firstly, the NO2/NOX emission ratio of road traffic has increased during the last two decades.
The observed increase of the NO2/NOX emission ratio for road traffic and the resulting higher NO2 emission is, thus, one reason for the observed stagnation of NO2 pollutioNO21–14].
The study suggests RAC and HESC are beneficial for concrete elements with larger surface area to depth ratio, like road pavements, floorings, reinforced concrete slabs, and precast elements.
Other factors that could increase this ratio include road salt entering a water supply from runoff, desalination, anion exchange treatment, or brine from sodium hypochlorite generators (used to disinfect drinking water) leaking into a water supply.
For the new tests, the existed simulator was upgraded to allow simulation of lever propulsion on various gear ratios and road inclinations.
For the experiments, we developed a special mechatronic wheelchair simulator that allows simulation of lever propulsion on various gear ratios and road inclinations.
The in-situ and stress-dependent resilient modulus and Poisson's ratio of the road materials were estimated from field strains.
In case of distance from fault, river and road, ratio to distance/proximity is used to understand the level of influence on landslide occurrence.
In the numerical examples, the proposed method is verified by comparing it with the conventional method, and it is found that the velocity, the vehicle to bridge mass ratio and the road roughness have a significant influence on separation.
Haussmann thought about ratios - a road 8m wide equals a building 12m high, doorways are a uniform 1.20m across.
