In this paper, we take a hard look at the performance of REMOTE, a sensor network based application that provides a detailed picture of a boat movement, individual rower performance, or his/her performance compared with other crew members. The application analyzes data gathered with a WSN strategically deployed over a boat to obtain information on the boat and oar movements. Functionalities of ...

An innovative robotic boat has been developed for performing bathymetric mapping of very shallow coastal, estuarine and inland waters. The boat uses a Small Waterplane Area Twin Hull (SWATH) design to provide natural platform stability for a multibeam sonar payload, and a navigation system automatically guides the boat in a “lawn-mowing” pattern in order to map a region of interest. Developed i...

A new generalized Voronoi diagram is defined on the surface of a river with unifonn flow; a point belongs to the territory of a site if and only if a boat starting from the site can reach the point faster than a boat starting from any other site. If the river runs slower than the boat, the Voronoi diagram can be obtained from the ordinary Voronoi diagram by a certain transformation, whereas if ...

We show that overloading is NP-complete. This solves exercise 6.25 in the 1986 version of the Dragon book.

We describe the inspiration, development, and deployment of a novel cocktail device modeled after a class of water-walking insects. Semi-aquatic insects like Microvelia and Velia evade predators by releasing a surfactant that quickly propels them across the water. We exploit an analogous propulsion mechanism in the design of an edible cocktail boat. We discuss how gradients in surface tension l...

the form of dragon has been appeared during the history of iran art in different formats whit mysterious contents. in fact, it is the only mythical character that is in collection with the rest ancient earthly animals. dragon with its scaly serpent, like body, is also one of the twelve zodiac signs in the world. in most of the old pictures, figures or written texts, they are explained with a bo...

Biodiesel is considered for mixing with fishing boat fuels to adjust their fuel cha...

Lévy’s dragon curve [P. Lévy, Les courbes planes ou gauches et les surfaces composées de parties semblables au tout, J. Ecole Polytechn., 227-247, 249-291 (1938)] is a well-known self-similar planar curve with non-empty interior. We derive an arithmetic expression for the coordinate functions of Lévy’s dragon curve, and show that the 3 2 -dimensional Hausdorff measure of the graph of each coord...
