FULL-SCALE WAVE ATTACK OF UNIFORMLY SLOPING SEA DYKES

Wave Hindcast Study of the Caspian Sea

The significant effect of waves on coastal and marine activities urges the precise identification of wave characteristics using field measurements, theoretical studies, physical modeling or numerical simulations. In order to study thoroughly the wave climate in the Caspian Sea, a wave modeling and hindcast project was performed by Iranian National Center for Oceanography. In this study, one of ...

Experimental investigation of wave parameters effect on damage of the berm reshaped seawall under irregular wave attack

This paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. The experiments of physical modeling of this research have been done in the flume of the Soil Conservation and Watershed Management Research Institute (SCWMRI). The waves applied to the structure model are irregular and ...

Cube Attack against Full Kravatte

This note analyzes the security of Kravatte against the cube attack. We provide an analysis result which recovers the master key of the current version of full Kravatte with data and time complexities 2136.01, and negligible memory. The same could be applied to the first version of Kravatte with complexities of 238.04, which could be carried out in practice. These results are possible thanks to...

On the Optimum Directivity of Uniformly Spaced Broadside Arrays of Parallel Half-Wave Dipoles (RESEARCH NOTES)

The nominal directivity for uniformly spaced broadside parallel half-wave dipoles associated with a uniform excitation is evaluated. The amplitude distribution for an optimized directivity is then obtained for different numbers of elements with the separations between the dipoles as a variable. The optimum and nominal directivities are compared for different spacings of the elements. While thes...
