The concepts studied during Offset Stream Technology (OST) test were all designed to produce directional jet noise reduction in a separate flow engine configuration by redirecting the fan stream relative to the core stream, creating a thicker fan flow on one side of the jet. Previous studies, conducted at bypass ratios of five or less showed that lower noise levels would result on the thickened...

Algebraic multigrid (AMG) is an efficient multilevel method for solving large sparse linear systems obtained from the discretisation of scalar elliptic partial differential equations. AMG can be used to compute powerful preconditioners for use with Krylov subspace methods. We report on the design and development of an efficient, robust and portable implementation of AMG that is available as pac...
متن کاملIs ICT Adoption for Agriculture Still an Important Issue?
Attempts to understand and improve the effectiveness of ICT Adoption for Agriculture have been at the forefront of national and regional policies ever since computers became available for agricultural management and production. EFITA* has been sharing these efforts via it’s conferences and the collection of data sets to identify ICT Adoption constraints and trends over time. The 5th EFITA/WCCA ...

Upper left panel, Electrical signals are recorded from a Xenopus oocyte expressing the circadian photoreceptor melanopsin in response to illumination with blue light. Upper right panel, Photocurrent recorded from an oocyte expressing melanopsin and the TRPC3 ion channel in response to illumination at various wavelengths. Peak activation of melanopsin signaling occurs at about 470 nm, which corr...
