A case of Farber's disease associated with athyreosis is reported in a Belgian infant born from consanguineous parents. A detailed clinical observation made from the early onset of symptoms until death of the patient at age of 22 months, together with radiological, morphological and biochemical data confirmed the diagnosis of Farber's disease and its(More)
— Landing on distant planets is always a challenging task due to the distance and hostile environments found. In the design of autonomous hazard avoidance systems we find the particularly relevant task of landing site selection, that has to operate in real-time as the lander approaches the planet's surface. Seeking to improve the computational complexity of(More)
The observer presented in this paper, which was based on the use of three minimalistic bio-inspired Visual Motion Sensors (VMS) detecting Optic Flow (OF) cues, states was intended as a backup solution in the case of Inertial Measurement Unit (IMU) failure. Contrary to most previous Guidance Navigation and Control (GNC) solutions for planetary landing, which(More)
