The oxygen uptake rate (OUR) is an important quantity to the aerobic activated sludge processes. It can be used to model and to optimize the system, for monitoring the process efficiency, and as a toxicity indicator in wastewater treatment plants, among other applications. The lack of online and reliable sensors to measure this significant quantity has motivated the development of software sensors...
This paper deals with the problem of localizing a group of robots. Each robot is equipped with an autonomous self-localization system based on both high-rate odometers and a front camera detecting sporadically simple visual landmarks placed on the floor at known positions and with a known attitude within a given 2D reference frame. In addition, the robots can share their own states to improve localization...
Visual odometer is a technique that permit to measure the velocity of a vehicle by the elaboration of a video source from a camera solidly fixed to it. Actual cameras are cheap and have high resolution and fast frame rate, with these characteristics it become really easy to estimate the ego motion with a really high accuracy. It is possible to achieve a resolution in position around 20–30 cm. The...
