Until recently, physical models were the only way to investigate into the details of breakwaters behavior under wave attack. From the numerical point of view, the complexity of the fluid dynamic processes involved has so far hindered the direct application of Navier-Stokes equations within the armour blocks, due to the complex geometry and the presence of strongly non stationary flows, free bou...

Autonomous Underwater Vehicles (AUVs) are suitable for underwater observation, since they can swim freely without an umbilical cable. This paper proposes a robust navigation method for AUVs operating around artificial structures such as piers, quays and breakwaters. This method consists of a State Estimator and a Guidance System, enabling localization in the configuration map as well as followi...

The human thermal comfort is the state of mind, which affected not only by physical and body’s internal physiological phenomena but also clothing properties such as resistance clothing, insulation, area factor, air relative humidity. In this work, we extend one-dimensional Pennes’ bioheat transfer equation adding protective layer. transient temperature profile with layer at different time steps...

Breakwaters are the important and the costly ones of the marine structures. Composite breakwater is one of the common types in the world. Because of the progress in marine industry in Iran in recent years, designers have noticed this structure. Because of the sensitivity of composite breakwater to environmental conditions, also construction costs, difficulty of repair and maintenance and import...
