In this paper a new approach for the underwater sensor network based on the blue-green laser has been proposed. We describe the application of the underwater sensor network in the undersea exploration, and discuss the difficulties in the traditional the underwater acoustic sensor network. A basic of prototype of underwater laser sensor network has been advanced, which include the architecture o...

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

In this paper, we present the first glider capable of navigating an aperiodic tiling. It inhabits a four-state outer-totalistic cellular automaton, and operates on generic tilings of quadrilaterals. We investigate its behaviour on both the P2 (kite and dart) and P3 (rhombus) Penrose tilings, and characterise the different types of path it can follow. Further, we note that the path followed by t...

Otto Lilienthal's pioneering work on gliders helped form the basis for development of powered aircraft. His death following a glider crash in 1896 was officially ascribed to fracture of the cervical spine. However, the clinical details assembled here make it more likely that he died from head trauma with resulting complications, possibly including intracranial hematoma.

Elementary cellular automata (ECA) rule 9 and rule 74, members of Wolfram’s class II, could generate a host of gliders and complicated glider collisions by introducing the hybrid mechanism, which are much richer than those generated by ECA rule 110. A systematic analysis is carried out to show the simulation results.

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...

Autonomous Underwater Vehicles (AUVs) are a common tool used by oceanographers to study oceans. Most AUVs are operated by pilots who are able to interpret environmental information to make effective mission decisions; this function requires an understanding of the hardware and software of these complex systems. To enable oceanographers and pilots to more easily manage a fleet of gliders, new me...

Laser sensing has been applied in various underwater applications, ranging from underwater detection to laser underwater communications. However, there are several great challenges when profiling underwater turbulence effects. Underwater detection is greatly affected by the turbulence effect, where the acquired image suffers excessive noise, blurring, and deformation. In this paper, we propose ...

In this paper, we propose a novel technique to reconstruct 3D surface of an underwater object using stereo images. Reconstructing the 3D surface of an underwater object is really a challenging task due to degraded quality of underwater images. There are various reason of quality degradation of underwater images i. e. , non-uniform illumination of light on the surface of objects, scattering and ...
