BREAKWATER ARMOR DISPLACEMENT THRESHOLDS: A POSSIBLE CORRELATION WITH CUMULATIVE WAVE ENERGY

Large-displacement Lightweight Armor

Large-displacement Lightweight Armor Randomly entangled fibers forming loosely bound nonwoven structures are evaluated for use in lightweight armor applications. These materials sacrifice volumetric efficiency in order to realize a reduction in mass versus traditional armor materials, while maintaining equivalent ballistic performance. The primary material characterized, polyester fiberfill, is...

Probabilistic Neural Network for Predicting the Stability numbers of Breakwater Armor Blocks

Probabilistic Neural Network for Predicting the Stability numbers of Breakwater Armor Blocks Doo Kie Kim1, Dong Hyawn Kim2, Seong Kyu Chang1 and Sang Kil Chang1 Summary The stability numbers determining the Armor units are very important to design breakwaters, because armor units are designed for defending breakwaters from repeated wave loads. This study presents a probabilistic neural network ...

Numerical Simulation of Wave Overtopping Over Composite Berm Breakwater

Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...

Skew Minimization Problem with Possible Sink Displacement

In applications such as design of integrated circuits (chips), it is sometimes required to connect the terminals (receivers) and the central vertex (source) by a weight-minimal tree where the signal delays between the source and the terminals are the same or differ by a minimal value. Simple necessary conditions for existence of the desired tree, heuristic rules for displacement of the terminal...
