3-D reconstruction by extended depth-of-field in failure analysis - Case study II: Fractal analysis of interlaminar fracture in carbon/epoxy composites
(Pergamon-Elsevier B.V. Ltd, 2012-10-01)
This work aims to evaluate the fractal behavior of fracture surfaces in laminated carbon/epoxy composite material, by conducting double cantilever beam (DCB) tests and comparing fractal values against critical (at notch ...

Stereo Time-of-Flight with Constructive Interference
(IEEE, 2014)
This paper describes a novel method to acquire depth images using a pair of ToF (Time-of-Flight) cameras. As opposed to
approaches that filter, calibrate or do 3D reconstructions posterior to the image acquisition, we ...
3-D reconstruction by extended depth-of-field in failure analysis - Case study I: Qualitative fractographic investigation of fractured bolts in a partial valve
(Pergamon-Elsevier B.V. Ltd, 2010-03-01)
Extended depth-of-field 3-D reconstruction is an image processing based technique associated to optical microscopy for qualitative or quantitative analysis of surfaces topographies. It is proposed here as a low-cost ...
The short-selling skill of institutions and individuals: a market-wide and out-of-sample analysis
(2018-02)
Using market-wide data from the Brazilian stock lending market, we find strong evidence of short-selling skill for some institutions and individuals. Skilled short-sellers present out-of-sample performance persistence, ...
