Two cases of rhabdomyolysis with renal failure followed by hypercalcaemia are reported. Both had major hyperphosphataemia and hypocalcaemia, requiring haemodialysis. Hypercalcaemia developed during the diuretic phase, when renal function was still abnormal, and before phosphate blood levels had returned to normal. Soft tissue calcifications occurred in one(More)
This paper proposes a method to characterize the space explored by a mobile robot during a mission. Because of localization uncertainty, the area osculated by a sensor at a given time is uncertain too. The problem is modeled by using intervals to represent trajectory uncertainties and a “visibility function” to describe the area in view at a given time. A(More)

This report describes a methodology for automated ship and wake detection in space-based synthetic aperture radar (SAR) imagery. The methodology incorporates a multistage approach involving several algorithms which can be applied according to requirements, computational resources, and scene composition. Wc suggest that the localized K-distribution be used(More)
Building an accurate digital terrain model (DTM) of the seabed is a key issue for various military and civilian hydrographers applications. In the past decades, the emergence of autonomous underwater vehicles (AUV) offers new methodologies to collect the bathymetric data used in the estimation of the DTM. In our study, we use the DAURADE AUV platform which(More)
In the underwater environment, the needs of data acquisition have significantly increased over the last decades. As electromagnetic waves show poor propagation in sea water, acoustical sensing is generally preferred. However, the emergence of small and low cost autonomous underwater vehicles (AUV) allow for rethinking the underwater use of optical sensors(More)
