Wave Communication across Regular Lattices [PDF]
Physical Review Letters, 2009 We propose a novel way to communicate signals in the form of waves across a d - dimensional lattice. The mechanism is based on quantum search algorithms and makes it possible to both search for marked positions in a regular grid and to communicate between two (or more) points on the lattice. Remarkably, neither the sender nor the receiver needs to know

Motion Response Characteristics of Small Fishing Vessels of Different Sizes among Regular Waves
한국해양공학회지, 2023 The motion of small fishing vessels is significantly affected by small waves, leading to accidents, such as capsizing or sinking. This paper presents the results of two types of basin tests.

A Numerical Study on the Performance of the 66k DWT Bulk Carrier in Regular and Irregular Waves
Journal of Marine Science and Engineering, 2023 Accurate resistance performance evaluation is essential to predict the minimum propulsion horsepower required for ships in real sea. Therefore, in this paper, the added resistance performance of K-Supramax in various wave conditions was calculated using ...

Visualization of the Onset of Scour under a Pipeline in Waves
Applied Sciences, 2020 This paper visualizes the onset of scour under a pipeline in regular waves and studies the mechanism in this process. After the test started, the sand particles near the downstream mudline began to oscillate periodically, probably due to the distribution

On the Comparative Seakeeping Analysis of the Full Scale KCS by Several Hydrodynamic Approaches
Journal of Marine Science and Engineering, 2020 The main transport channel of the global economy is represented by shipping. Engineers and hull designers are more preoccupied in ensuring fleet safety, the proper operation of the ships, and, more recently, compliance with International Maritime ...

Frontiers in Marine Science, 2022 The coastal area near islands has become a key area for aquaculture because of the long offshore distance and suitable wave conditions. There is a topographic change near the islands, and the reflected waves generated by the topography modify the wave ...

The regularity of geodesics in impulsive pp-waves [PDF]
General Relativity and Gravitation, 2013 We consider the geodesic equation in impulsive pp-wave space-times in Rosen form, where the metric is of Lipschitz regularity. We prove that the geodesics (in the sense of Caratheodory) are actually continuously differentiable, thereby rigorously justifying the $C^1$-matching procedure which has been used in the literature to explicitly derive the ...

Journal of Marine Science and Engineering, 2023 Overtopping flow velocity (OFV) and overtopping layer thickness (OTL) are essential parameters in breakwater design. Several empirical equations to predict these parameters are available in many works of literature, but most of the equations were derived
