Degradation of alumina and zirconia toughened alumina (ZTA) hip prostheses tested under microseparation conditions in a shock device
This paper considers the degradation of alumina and zirconia toughened alumina vs. alumina for hip implants. The materials are as assumed to be load bearing surfaces subjected to shocks in wet conditions. The load is a peak of force; 9 kN was applied over 15 ms at 2 Hz for 800,000 cycles. The volumetric wear and roughness are lower for ZTA than for alumina. The long ZTA ageing did not seem to h...
متن کاملWear simulation of total hip prostheses with polyethylene against CoCr, alumina and diamond-like carbon.
The wear of ultra-high molecular weight polyethylene acetabular cups was studied with a new biaxial hip wear simulator using diluted calf serum as a lubricant. The cups had been packed and gamma-irradiated in argon. The cups were articulated against two established types of femoral head, alumina and CoCr, and one experimental type, CoCr coated with diamond-like carbon (DLC). The diameter of the...
متن کامل3D Surface Reconstruction and Recognition
In this paper we propose a novel 3D face recognition system. Furthermore we propose and discuss the development of a 3D reconstruction system designed specifically for the purpose of face recognition. The reconstruction subsystem utilises a capture rig comprising of six cameras to obtain two independent stereo pairs of the subject face during a structured light projection with the remaining two...
متن کاملRecognition and Surface Reconstruction of 3d Objects
The importance of object recognition has been increasing in various fields in view of its vast potential for automating time critical, hazardous, sensitive operations. Depending upon the kind of data available about the object such as intensity data or range data methods have been developed. For 2D object recognition intensity data is all that is required to process but for 3D object recognitio...
متن کامل3d Surface Reconstruction from Horizons
In this paper we present a general solution to the problem of 3D reconstruction from the analysis of luminance edges, which takes into account possible viewer-dependent characteristics of such contours. The method first proceeds by matching contours in a loose fashion, so that both sharp edges and horizons are included. Classical stereometric methods allow us to detect sharp edges and rule out ...
