Rip currents near coastal structures commonly occur in Lake Michigan the Great Lakes region of United States. Lack timely warning due to undocumented characteristics rip and no assessment tool can contribute tragic drownings incidents. In this paper, we characterized current occurrences breakwater developed an for providing warnings beachgoers at study site, City Port Washington, WI. Characteri...

Drowning accidents at beach in Japan are caused by rip currents. To reduce these accidents, a new technology that can detect currents and notify beachgoers using the Internet of Things (IoT) Artificial Intelligence (AI) was proposed. However, studies on effect visualizing or considering optimism bias have not been conducted. This study investigates if visualization might help preventing drownin...

The existing theory for shore-transverse rhythmic sand bars relies on morphodynamic instabilities involving the wave-driven longshore current and rip currents. Intriguingly, transverse finger are common coasts with sediment excess, something not related to those Here we show that, if actual beach profile is above equilibrium profile, cross-shore transport can induce an instability triggered by ...

Rip currents are strong water channels flowing away from the shoreline. They can occur on any shore with breaking waves. play a significant role in changing topography of shallow regions by transporting large amounts bed material offshore. Moreover, they pose danger for people living nearshore zones and surfers cause hundreds deaths annually worldwide. Therefore, rip current generation characte...

BACKGROUND How accurately do people perceive extreme water speeds and how does their perception affect perceived risk? Prior research has focused on the characteristics of moving water that can reduce human stability or balance. The current research presents the first experiment on people's perceptions of risk and moving water at different speeds and depths. METHODS Using a randomized within-...

aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...
