Abstract Aerial and underwater drones are one of the most attractive technologies to a large number applications, extending from surveillance natural reserves monitoring structures. For these reasons, innovative uncommon applications constantly appearing. Within this context, capable operate continuously efficiently in air water can extend standard aerial capabilities allowing inspections harbo...

Abstract: This paper focuses on a dolphin-like swimming hydrodynamics problem for a biomimetic amphibious robot capable of both fishand dolphin-like swimming modes. A Lagrangian reduction has been established in terms of rigid-body dynamics. For robust gait control, a central pattern generator-based approach is incorporated into the model serving as explicit joint angle control. Consequently, a...

The transition from aquatic to terrestrial locomotion was a key development in vertebrate evolution. We present a spinal cord model and its implementation in an amphibious salamander robot that demonstrates how a primitive neural circuit for swimming can be extended by phylogenetically more recent limb oscillatory centers to explain the ability of salamanders to switch between swimming and walk...

Up to the present, the experimental infection with Paragonimus ohirai larvae in the gastropod molluscus belonging to 5 genera including 10 species has been carried out by the author and some other workers. The results showed that this fluke has a high infectivity to amphibious molluscs such as Assintinea parasitologica, A. yoshidayukioi, Paludinella japonica and Oncomelania nosophora rather tha...

A variety of data mining techniques are under evaluation on the spatial data of concern in our setting. We are planning to integrate a number of these techniques into our geospatial system (GIDB). Three approaches are under special consideration and are described in the paper. A COTS data mining system has been successfully used to develop predictive models of near-shore conditions such as wave...

in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...
