Titanium is commonly used for dental implants because of its unique ability to get incorporated into living bone. There is an ongoing development to obtain better anchorage and surface properties such as roughness and chemical composition are modified to reach this. In this study titanium dental implant surfaces were characterised by recording the topographical changes induced by each individua...

1. QUANTIFYING SURFACE TOPOGRAPHY DIFFERENCES USING CCFmax AND Ds Topography measurements play an important role in surface and nano-metrology, production quality control, tribology, bio-technology and forensic science [1]. Dozens of surface parameters are specified in national and international standards [2, 3]. Although none of these are designed for topography comparisons, statistical method...

Real-Time Mobile 3D Topography System is a GIS (Geographic Information System) based on Client Server. In our daily life, this system could be useful in the traveling, mining, and etc,. In this paper, we developed a Real-Time Mobile 3D Topography System for embedded system. This system is consisted by a Server and a client. The client based on Intel Sitsang, can orientate the position through t...

The capability of evaluating and managing rockfall related risks is largely based on numerical modelling. Nevertheless, the reliability and accuracy of rockfall models is greatly affected by the strong uncertainty and spatial variability which characterise all the relevant parameters. In particular, 3D effects related to the variability of slope geometry and micro-topography play a major role i...

Objective(s): During the last years with increasing resistant bacteria to the most antibiotics bacteriophages are suggested as appropriate treatment option. To investigate lytic activity of bacteriophages there are indirect microbial procedures and direct methods. The present study to complement microbial procedures and investigate ultra-structural characteristics of infection bacterium-phage u...

In a 3D stacked IC, through-silicon vias (TSVs) are utilized to interconnect dies vertically. In one common TSV practice, via-first TSVs directly connect the first metal layer of a die and the top metal layer of the die above it. However, the landing pads on the first metal layer, due to their large area and presence of features with widely varying sizes, may result in serious topographic error...

Material and methods Computer Aided Design and Manufacturing in bracing is based on the introduction of appropriate data to the computer using anthropometry. The best data can be delivered by precise 3D surface topography supplemented with Xray and other necessary radiographic modalities. The surface topography scanning used for this study is based on structured light projection. Scanning the s...

This paper demonstrates how a new shape from shading scheme can be used to extract topographic information from 2D intensity imagery. The shape-from-shading scheme has two novel ingredients. Firstly, it uses a geometric update procedure which allows the image irradiance equation to be satisfied as a hard-constraint. This not only improves the data-closeness of the recovered needle-map, but also...

The catalytic cutting of few-layer graphene is nowadays a hot topic in materials research due to its potential applications in the catalysis field and the graphene nanoribbons fabrication. We show here a 3D analysis of the nanostructuration of few-layer graphene by iron-based nanoparticles under hydrogen flow. The nanoparticles located at the edges or attached to the steps on the FLG sheets cre...
