The role of seagrasses in regulating epiphytes is a question of central importance for understanding structuring processes in seagrass communities. This study tests the hypothesis that seagrasses are not simply bare substrata for microalgal attachment, but rather influence community composition by altering competitive interactions between different microalgal groups. The effects of wave exposur...

Aiming at the problem of low resources utilization rotating blades in selection process aeroengine fan rotor blades, this paper takes first-order bending dispersion, torque and gravitational moment difference as criteria minimum remaining optimization goal. An intelligent algorithm based on collocation degree is proposed achieves efficient full blades. multiple installations adjustments assembl...

Improving the efficiency of compressors has been one of the most important goals of researchers over the years. In this paper, three different methods are presented for parameterization and blade optimization of axial flow compressor. All methods consist of flow analysis tool, optimization algorithms, and parametric geometry generation tool, that are different in each approach. Objective functi...

Laser direct deposition provides an attractive and cost effective means for repairing or remanufacturing high value engineering components. This study demonstrates the successful repair of defective voids in turbine airfoils based on a new semi-automated geometric reconstruction algorithm and a laser direct deposition process. A Boolean difference between the original defective model and the fi...
