Manatee researchers and wildlife managers continue to explore alternatives for optimally protecting manatees by means of regulatory approaches as well as technological solutions. Florida first began regulating boat speeds as a way of reducing risks to manatees over 30 years ago. Various types of manatee-protection zones have been established throughout Florida with the understanding that reduci...

Many existing phenomena in nature are considered new design ideas in various fields of industry. Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. By performing bionic review, the researchers found the penguins by delivering air locked under their wings and creating air bubbles, the drag significant...

In competitive rowing, the fluctuations in boat velocity during the rowing cycle are associated with an increased water resistance of the boat as compared with a boat moving at a constant velocity. We aimed to quantify the influence of the increased water resistance on race time using a mathematical approximation, based on the increase in physiological power being proportional to the 2nd power ...

This paper describes a method to detect, measure the speed, and extract statistics of boats moving on a wide water surface using a single image stream taken from grayscale camera. The approach is based on a background subtraction technique combined with classification and tracking to improve robustness; it provides a stable detection even with sea waves and strong light reflections. The method ...

Penelitian tentang penggunaan serat alam dalam berbagai bidang teknik semakin berkembang. yang berkembang menginginkan suatu bahan mudah diperoleh, diolah sesuai peruntukannya, murah, memenuhi persyaratan mekanik dan fisik serta ramah terhadap lingkungan. Penggunaan material Bamboo (Bamboo Strip Reinforced/BSR) dengan sistem laminasi, untuk pembuatan Speed Boat menjadi alternatif sebagai piliha...

In this research paper, the proposed concept is to safeguard the uneducated fisher men crossing the border and guides them to go in a right path and save their life. Our proposed idea helps in locating the Fishing boat using GPS system. This information is transmitted using wireless mode to the control system. Then by detecting the latitude and longitudinal location of the Fishing boat, the con...

Rowing has a 150 yr+ competitive history. Examining results from historic races like Oxford-Cambridge (established 1829) and the world championships (established 1893) reveals a linear increase in boat speed by 2-3% per decade. Boat velocity increases if propulsive power is increased and/or power losses are reduced. Over time, the propulsive power capacity of elite rowers has increased. Part of...
