| Experimental results, such as static pressure distribution, lift coefficient, wake and 3-D flow effects, are compared with the 2-D test results. | |
| Determination f brasion/erosion strength is measured based on ASTM C1138, which can evaluate the abrasion/erosion strength of concrete under water and steel ball suspension. | |
| The results showed, the usage of polymeric foam support improves the forming condition by achieving to the parts with higher wall angle. | |
| This transitive relation, transfers the original information considered as a special code from the source in a form of subsets of special codes to hyper edges and therefore as a result, it puts each hyper edge in a one to one correspondence with a subset of special code. | |
| Investigation of effect of nonlinear isolators on the seismic performance of base-isolated rectangular liquid containers incorporating liquid-structure interaction | |
| Formation of Al-Cr rich intermetallic compounds in the joining area increased the hardness of joining zone more than two times of hardness of join without this components (140±5 HV and 60±5 HV). Furthermore, in-situ synthesis joining increase ultimate tensile strength of the joint from 40±5 Mpa to 130±10 Mpa | |
| The aim of this research was to assess the trends and reasons of vulnerability of the Great Karun Water System to hazards with an especial focus on water quality as the main attribute of concern in the basin. | |
| The simulation results show that the proposed algorithm, considering the characteristics of tasks and resources, has significant efficiency and effectiveness in the cloud environment, especially at high workloads. | |

| Effect of Temperature Rise on the Concrete Containing Recycled Metal Spring and Its Comparison with Ordinary Fibres | |
| It was found that the particles are broken up during friction stir welding, and the severity of the breaking up of particles and grain size in the stir zone increase with increasing rotational speed. Consequently stability of grains increases. | |
| Areversed cyclic load was applied to the tip of the full scale exterior beam-column specimen. | |
| Experimental and Numerical study of piano key weir with upstream nose and semicircular section at the outlet | |
| The simulation results show the satisfactory performance of the proposed control scheme with high dynamics and low ripple. | |
| It was observed that over the permeable bed, the analytical equation estimates the sequent depths ratio better than the Blunger equation and also the sequent depths changes show more dependency on the Froude number in comparison to the bed permeability. | |
| -Thermodynamic Mathematical Model of Stirling Engine to Improve Efficiency and Power | |
| Accordingly, solutions will be needed to provide an appropriate ambiance for such a situation. Therefore, before running, the chains must be fully controlled, which requires the definition of chaining rules. | |
| The associated results show that in P300 speller systems, the temporal filters outperform the spatial filters. | |

| Horizontally curved bridges Near-fault earthquake Deck rotation Field testing | |
| The experimental results show a high accuracy of the proposed method in phenome recognition, indicating a significant improvement comparing with other state-of-the-art methods. | |
| The results are validated using numerical and theoretical data available in the literature. | |
