This paper investigates the wave transmission through artificial reefs utilised as low-crested breakwaters to mitigate coastal erosion and reduce energy. The study utilises DualSPHysics smoothed particle hydrodynamics (SPH) solver evaluate effectiveness of such structures. Wave coefficients were computed for various reef configurations conditions. Results indicate that shifted configuration pro...

This paper is focused on microstructure of protective layers created by co-deposition of Al and Si on nickel base superalloys INCO 713 LC and INCO 738 LC after thermal and thermal-stress exposition and on microstructure of basic materials (substrates). The contribution also shows creep tests results for both superalloys with and without a protective layer.

nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. these types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. in the current study, the performance of floating breakwater (fbs) under regular waves was studied using the physical modeling method. for the mode...

The necessity to implement solutions that guarantee the protection and recovery of coastal area makes submerged breakwater employment is evaluated as a viable variant application because these works contribute conservation natural aesthetic conditions beaches, which part tourist product marketed. However, parameters intervene in their functional design are not very well established, propitiatin...

In this paper, we investigate the wave damping mechanism by sinusoidal submerged breakwater using a half-linear Shallow Water Equations (SWE). We solve equations analytically multi-scale expansion method to obtain elevation profile over with specific height and length. Then, get information about how much caused breakwater, derived analytical solution reflection transmission coefficient. Furthe...

In chemical, biological, radiological, and nuclear protective clothing, a layer of activated carbon material in between two textile layers provides protection against hazardous gases. A cylinder in cross flow, sheathed by such material, is generally used to experimentally test the garment properties. This is, however, complicated and predictive models are needed. We present a computational flui...

The beneficial effect of clothing on a person is important to the criteria for people exposure to radiant heat flux from fires. The thermal protective performance of multilayer thermal protective clothing exposed to low heat fluxes during dry and wet conditions was studied using two designed bench-scale test apparatus. The protective clothing with four fabric layers (outer shell, moisture barri...

The analysis and optimal design of a multi-layered microstrip sensor for measuring moisture content of ricegrain are described. The microstrip sensing structure consists of three layers: substrate, protective layer and semi-infinite grain medium. The effective dielectric constant, characteristic impedance and attenuation or insertion loss of this structure are calculated at various moisture con...
