Monitoring and tracking of fleets can represent a great improvement in security and safety when transporting hazardous goods by road. In this paper we propose a complete monitoring and tracking solution for truck fleets, which is able to check at the same time the position and the mechanical status of the vehicle, as well as the conditions in the cargo bay. The system exploits battery-powered environmental...
In this paper we propose a flexible two-level architecture for wireless communications in areas where the deployment of wired networks is not feasible, as in disaster recovery scenarios. The first layer of communication guarantees medium-range transmission, being based on the IEEE 802.11s draft for Mesh Networking. The lower one is instead optimized for short-range, low-power communication between...
Concrete tiles artificially contaminated with field strains of Escherichia coli and Salmonella kedougou, with and without the presence of bovine faecal matter, to simulate visually clean and visually dirty surfaces respectively, were cleaned using a specially designed mechanical rig. Cleaning was carried out using (1) water under mains pressure, (2) water under pressure, (3) water under pressure with...
The design of a data acquisition system (DAQ) for a positron emission tomography scanner is reported. The PET system, based on long axially oriented scintillation crystals, read out by hybrid photon detectors (HPD), allows 3D parallax-error free Compton enhanced gamma reconstruction. The DAQ system is composed of several readout cards, each one associated with a module of the PET scanner, and of a...
