Sparse Volumetric PZT Array with Density Tapering [PDF]
2018 IEEE International Ultrasonics Symposium (IUS), 2018 Volumetric medical ultrasound imaging currently provides either high resolution or high frame rates. We propose a sparse array probe with only 256 elements that are density tapered. All elements are directly wired to an ultrasound engine, thus being flexible in transmission and reception. Here we present the design, realization, and characterization of

Selected properties of European beech (Fagus sylvatica L.)
Journal of Forest Science, 2008 The paper deals with the variability of tree-ring width, with the density and swelling (volumetric swelling and swelling in individual anatomical directions) of wood from two different locations.

Densely Packed and Highly Ordered Carbon Flower Particles for High Volumetric Performance
Small Science, 2021 Carbon materials with high specific surface areas are ideal support materials for many applications. However, high specific surface area and large pore volume usually render them with low bulk density, which is undesirable for applications aiming at high

The variability of selected properties of beech (Fagus sylvatica L.).
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007 Variability of ring width, wood density and swelling in beech from two different areas was analysed. The variability of each property was described along the stem radius. The analysis proved that the ring width decreased in direction from the pith to the
