  • Mobile UW–ASN framework with RSSI–based protocol for shallow river monitoring

    Approximately three–fourths of our planet's surface is covered by ocean and seas, a continuous body of water that is divided into several oceans and smaller seas. Water conditions determine climate that affects life on Earth. Whereas fresh water in lakes and rivers covers less 1%, its contamination significantly damages ecosystems. Within this research this paper proposes a framework with a ...

  • A Sound Projector for Acoustic Tomography and Global Ocean Monitoring

    Abstract—Long-range underwater acoustic systems, such as those used in ocean acoustic tomography, require low-frequency signals covering a broad frequency band. To meet this requirement, a novel design based on of a tunable narrow-band high-efficiency sound projector has been exploited. The projector transmits a frequency sweep signal by mechanically tuning a resonator tube (or organ pipe) ...

  • Path planning for marine fleet using heuristic approach

    Nowadays, the use of unmanned vehicles for border monitoring is taking over in order to reduce the effort of human operators. This paper addresses the problem of the coastal patrolling by proposing a solution based on unmanned underwater and surface vehicles. The focus of the work is on the design of the routes for the unmanned vehicles so as to optimise the limited mission range of the robotic ...
