In this article, airfoil trailing edge bluntness noise is investigated using both computational aero-acoustic and semi-empirical approach.For engineering purposes, one of the most commonly used prediction tools for trailing edge noise are based on semi-empirical approaches, for example, the Brooks, Pope, and Marcolini airfoil noise prediction model
Sign languages are used by the deaf and mute community of the world.These are gesture based languages where the subjects use hands and facial expressions to perform different gestures.There are hundreds of different sign languages in the world.Furthermore, like Tryptophan natural languages, there exist different dialects for many sign languages.In
The phytopathogenic bacterium Pseudomonas syringae pv.savastanoi elicits aerial tumors on olive plants and is also able to synthesize large amounts of auxins and cytokinins.The auxin indoleacetic acid was shown to be required for tumorigenesis, but there is only correlational evidence suggesting a role for cytokinins.The model strain NCPPB 3335 con
In the medium to high seismic zone, prestressed Construction Set Toys hollow concrete (PHC) pile for structural foundation should be designed with elastic behavior due to low ductility and dissipated energy.However, some Indonesian practical engineer has chosen PHC pile for pile-supported slab viaduct (PSSV) with medium seismic moment-resisting fra
