Visual SLAM algorithms allow localizing the Hats camera by mapping its environment by a point cloud based on visual cues.To obtain the camera locations in a metric coordinate system, the metric scale of the point cloud has to be known.This contribution describes a method to calculate the metric scale for a point cloud of an indoor environment, like
Helium nanodroplets irradiated by intense near-infrared laser pulses ignite and form highly ionized nanoplasmas even at laser intensities where helium is not directly ionized by the optical field, provided the droplets Fish contain a few dopant atoms.We present a combined theoretical and experimental study of the He nanoplasma ignition dynamics for
There is a growing demand for transparency along the agri-food chain, both from customers and governments.The adoption of blockchain technology to enable secure traceability for the management of the agri-food chain, provide information such as the provenance of a food product and prevent food fraud, is emerging rapidly, due to the inherent trust a
