This paper addresses the problem of mission control of Unmanned Underwater Vehicles (UUVs) through the Internet network. Its main focus is on the integration of a Petri Net based mission control system developed by the Instituto Superior Técnico using the CORAL environment, with the control system of ROMEO, a prototype ROV developed by the Robotics(More)
BACKGROUND Differential diagnosis of melanoma from melanocytic nevi is often not straightforward. Thus, a growing interest has developed in the last decade in the automated analysis of digitized images obtained by epiluminescence microscopy techniques to assist clinicians in differentiating early melanoma from benign skin lesions. PURPOSE The aim of this(More)
T he catamaran sea surface autonomous modular unit (SESAMO) was satisfactorily exploited for sampling the sea-surface microlayer and immediate subsurface in the Terra Nova Bay area of the Ross Sea during the XIX Italian expedition to Antarctica in January–February 2004. The SESAMO prototype robot, designed to collect data and samples for the study of the(More)
This paper addresses the problem of low cost actuator fault detection, diagnosis and accommodation for Remotely Operated Vehicles. The research is based on the analysis of the telemetry of Romeo, the over-actuated ROV developed by C.N.R.-I.A.N., operating both in nominal and different failure conditions. Results demonstrate how the monitoring of the(More)
BACKGROUND A single nucleotide polymorphism (61A>G) in the epidermal growth factor (EGF) gene has been implicated in both melanoma pathogenesis and increased melanoma risk. To further evaluate this association, we conducted a case-control study in a clinic-based Italian population. METHODS Individuals with less than 10 (N = 127) or more than 100 (N = 128)(More)
