A regularized nonlinear diffusion approach for texture image denoising
(2009-12-01)
In this paper a new partial differential equation based method is presented with a view to denoising images having textures. The proposed model combines a nonlinear anisotropic diffusion filter with recent harmonic analysis ...
Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
(2010-05-19)
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
Oxygen Diffusion in Ti-20Mo Alloys, used as Biomaterial, Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2012-01-01)
Titanium alloys are favorable implant materials for orthopedic applications, due to their desirable properties such as good corrosion resistance, low elasticity modulus, and excellent biocornpatibility. The research on ...
Numerical correction for the diffuse solar irradiance by the melo-escobedo shadowring measuring method
(2011-12-01)
The present paper deals with numerical corrections factors proposed as a function of the clearness index in order to correct the diffuse solar irradiance measured with the Melo-Escobedo Shadowring Measuring Method (ME ...
Diffusion of Interstitial Elements in Ti Alloys used as Biomaterials
(Trans Tech Publications Ltd, 2009-01-01)
Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of ...
Nitrogen diffusion in the Nb-1.0wt%Zr measured by mechanical spectroscopy
(Trans Tech Publications Ltd, 2008-01-01)
The scientific and technological development in the area of new materials contributed to several applications of niobium and its alloys in nuclear power plants as well as in aerospace, aeronautics, automobile and naval ...
Diffusion of Oxygen and Nitrogen in the Ti-15Mo Alloy used for Biomedical Applications
(Trans Tech Publications Ltd, 2012-01-01)
The Ti-15Mo alloy is a promising material for use as a biomaterial because of its excellent corrosion resistance and its good combination of mechanical properties, such as fatigue, hardness, and wears resistance. This alloy ...
Numerical Studies of Premixed and Diffusion Meso/Micro-Scale Flames
(2017-01-01)
This work reports a numerical investigation of premixed and diffusion meso/micro-scale flames, with homogeneous reactions, for two different cases involving CH4/air premixed dynamics flames and co-flow diffusion flame with ...
Rank diffusion for context-based image retrieval
(2016-06-06)
This paper presents an efficient diffusion-based re-ranking approach. The proposed method propagates contextual information defined in terms of top-ranked objects of ranked lists in a diffusion process. That makes the ...
Estimation of hourly, daily and monthly mean diffuse radiation based on MEO shadowring correction
(Elsevier B.V., 2014-01-01)
A statistical estimate model for the anisotropic diffuse fraction as a function of clearness index K-T is proposed to estimate hourly, daily and monthly diffuse irradiations. Global, diffuse and direct solar irradiances ...
