This paper presents a novel technique to estimate DCBs from GPS transmitters and receivers on-board Low Earth Orbit (LEO) satellites.The technique consists of obtaining the DCBs as residuals from the difference between the ionospheric combination of the code and the associated ionospheric delay.The ionospheric delay is computed with TOMION, a backg
This work aims at proposing an affordable, non-wearable system to detect falls of people in need of care.The proposal uses artificial vision based on deep learning techniques implemented on a Raspberry Pi4 4GB RAM with a High-Definition IR-CUT camera.The CNN architecture classifies detected people into five classes: fallen, crouching, sitting, stan
The sorption capacity of untreated and alkaline-treated coconut shaft biosorbents for the removal of Pb2+ from aqueous solution was investigated in batch experiments.Effects of contact time, biosorbent dose, initial metal concentration, and pH on the sorption capacity were investigated.Optimum Pb2+ removal of 17.6 and 22.1 mg/g by untreated and alk
