Our goal is to realize sea surveillance systems in which an image processor detects intruding objects such as boats in the sea. A difficulty of the sea surveillance systems is to detect moving objects such as boats inhibiting false detection caused by flapping, splashing and shiny surface of the sea. Firstly we pick up factors of false detection in sea surveillance. Secondly we propose a new su...

In the maritime industry, propellers are most commonly used form of propulsion and core to optimum performance a ship. As marine have complicated geometries, flow around propeller is also complicated. Generally, characteristics determined analysed by experiments like open water self-propulsion scale model tests which costly time-consuming at initial design stage. this study, CFD simulations wer...

Abstract The structural condition of bridges in Germany is often affected by aging and increased traffic loads. However, retrofitting or renewing all not always feasible due to limited resources. Indirect drive‐by monitoring with sensors on passing vehicles has been explored as a cost‐effective scalable alternative direct monitoring. In this study, we propose novel High‐Speed Monitoring (HSM) m...

Safe and efficient following of a time varying motion goal by an autonomous unmanned surface vehicle (USV) in a sea environment with obstacles is a challenge. The vehicle’s tracking capability is inherently influenced by its dynamics, the motion characteristics of the motion goal, as well as by the configuration of obstacles in the marine environment. We have developed an approach that utilizes...

stroke is one of the most common diseases among the elderly with high personal and societal costs. in recent years, robotic rehabilitation for stroke has become an active area of research for assistance, monitoring and qualifying the rehabilitation treatments. the key issue needed for improving rehabilitation system is that patient feedback should be taken into account by the robotic rehabilita...

This paper investigates the feasibility of using boats as data mule nodes, carrying medical ultrasound videos from remote and isolated communities in the Amazon region in Brazil, to the main city of that area. The videos will be used by physicians to perform remote analysis and follow-up routine of prenatal examinations of pregnant women. Two open source simulators (the ONE and NS-2) were used ...
