Quadtree-like pyramids have the advantage of resulting in a multiresolution representation where each pyramid node has four unambiguous parents. Such a centered topology guarantees a clearly defined up-projection of labels. This concept has been successful ...
A process of self-assembly induced by electro-chemical etching was used to produce nano and micrometer scale pyramid-structures on (100) surfaces of gold. The pyramids grew in a self-similar fashion with the facets aligned in (114) plane. Using the unique ...
The microstructural characterization of two titanium alloys, Ti5Al2.5Sn and Ti6Al4V, was performed. These alloys were selected as representatives of the alpha and alpha + beta titanium families, to investigate their possible application as structural mater ...
We determined the structure of the hydrated Cu(II) complex by both neutron diffraction and first-principles molecular dynamics, In contrast with the generally accepted picture, which assumes an octahedrally solvated Cu(II) ion, our experimental and theoret ...

We consider the construction of least squares pyramids using shifted polynomial spline basis functions. We derive the pre- and post-filters as a function of the degree n and the shift parameter Δ. We show that the underlying projection operator is entirely ...
A new criterion for the appearance of hot tears in metallic alloys is proposed. Based upon a mass balance performed over the liquid and solid phases, it accounts for the tensile deformation of the solid skeleton perpendicular to the growing dendrites and f ...
This paper describes the development of microelectrodes with integrated three-dimensional electrode structures. The integration of three-dimensional structures aims at an improvement of the electrode/tissue interface. Due to the increase in surface area th ...
