The rail-wheel interface is fundamental to explain the dynamic running behaviour of a railway vehicle.It must therefore be understood and among the parameters by which it is characterised, the one called "equivalent conicity" plays an essential role since it allows the satisfactory appreciation of the wheel-rail contact on tangent track and on larg
Background Noise Removal in Non-Contrast- Enhanced Ultrasound Microvasculature Imaging Using Combined Collaborative, Morphological, and Vesselness Filtering
Suppression of background noise in clutter filtered contrast-free ultrasound microvasculature images is an important step towards better visualization, accurate segmentation, and subsequent morphological analysis of vascular structures.While different approaches to tackling this problem have been proposed, the use of denoising and vessel-enhancing
Morphological description of a novel synthetic allotetraploid(A1A1G3G3) of Gossypium herbaceum L.and G.nelsonii Fryx. suitable for disease-resistant breeding applications.
Wild species of Gossypium ssp.are an important source of traits for improving commercial cotton cultivars.Previous reports show that Gossypium herbaceum L.and Gossypium nelsonii Fryx.have better disease resistance characteristics than commercial cotton varieties.However, chromosome ploidy and biological isolation make it difficult to hybridize dipl
