Submerged marine investigation still remains a puzzle. The motivation behind this paper is to address the issues in plan and improvement of submerged vehicles with hindrance shirking and moving help for administrator in marine condition utilizing fluffy rationale controller. A symmetrical, practical and little measured submerged Remotely Operated Vehicle (ROV) with three thrusters is intended f...

Autonomous sailing boats are an attractive solution to perform measurements at sea thanks to their low energy consumption. A fleet of such vehicles can also be used for adaptive sampling of an environmental field. In previous work, artificial potential fields have been used successfully in a local and real-time planner to carry out the autonomous navigation of one sailing boat. In this paper, w...

This article analyzes environmental security in the sphere of sea navigation, safety of navigation and tourism on the Adriatic Sea, bearing in mind that keeping marine environment healthy is one of fundamental factors of today’s national and international security. Likewise, secure underwater environment strengthens public security from hazards deriving from seafloor caused by human negligence ...

A new methodology is proposed for the design of navigation systems for autonomous marine vehicles. Using simple kinematic relationships, the problem of estimating the velocity and position of an autonomous vehicle based on motion sensor data available at different rates is solved by resorting to complementary multirate time-varying filters. The set-up adopted for filter design and analysis buil...

nowadays, using public transportation vehicles like metro in large cities are of significance, and exposure to whole-body vibration for the metro passengers is one of the physical contaminations. this paper is conducted with the aim of evaluating the passengers’ convenience and health both in sitting and standing conditions. the present study was done on the passengers of lines 1, 2, and 4 of t...
