Surface topography has a profound influence on the function of surface [...]

The aim of this work is to evaluate the applicability of the 3D model obtained through Structure-from-Motion (SFM) from unmanned aerial vehicle (UAV) imagery, in order to characterize bioerosion patterns (i.e., cavities for roosting and nesting) caused by burrowing parrots on a cliff in Bahía Blanca, Argentina. The combined use of SFM-UAV technology was successfully applied for the 3D point clo...

This MATLAB interface is aimed at analyzing and integrating two different imaging modalities optical topography system (OTS) and magnetic resonance imaging (MRI). MRI provides information about the anatomical structure of the brain, while OTS displays the changes in the cerebral blood flow in the form of a topographic image. Eight subjects underwent an MRI and OTS exams at Miami Children’s Hosp...

Surface topography is an efficient tool for the understanding of physical phenomena, especially if multiscale roughness analysis performed. However, observable scale range in a measured with 3D optical profilometers quite limited. Therefore, all scales linked to phenomenon might not be measured, which impedes correct surface. Stitching topographies, technique combining elementary topographic ma...

Enamel thickness is highly susceptible to natural selection because thick enamel may prevent tooth failure. Consequently, it has been suggested that primates consuming stress-limited food on a regular basis would have thick-enameled molars in comparison to primates consuming soft food. Furthermore, the spatial distribution of enamel over a single tooth crown is not homogeneous, and thick enamel...

To broaden the scope of inkjet printing, this paper focuses on printing of an organic silver complex ink on glass substrates towards the fabrication of metallic 3D microstructures. The droplet formation sequence of the inkjet printer is optimised to print continuous layers of metal. A brief discussion on orientation trials, aimed at optimising the print parameters, is followed by two different ...
