Classificação e recuperação de imagens por cor utilizando técnicas de inteligência artificial
(Universidade do Vale do Rio do Sinos, 2003-07-24)
Image retrieval and classification are today the subject of extensive research. This topic poses both theoretical and practical challenges as researchers attempt to give machines such as computers and robots the ability ...

Surface tension of flotation solution and its influence on the selectivity of the separation between apatite and gangue minerals
(SOC MINING METALLURGY EXPLORATION INC, 2009)
This work presents and discusses the influence of the surface tension (gamma(LV)) of methanol/water mixtures on the flotation response of apatite versus gangue minerals conditioned with flotation reagents (75 g/t cornstarch ...
Experimental investigation of gravitational gas separation in an inclined annular channel
(ELSEVIER SCIENCE INCNEW YORK, 2012-05)
The oil industry uses gas separators in production wells as the free gas present in the suction of the pump reduces the pumping efficiency and pump lifetime. Therefore, free gas is one of the most important variables in ...
Catalyst Recovery and Recycling Facilitated by Magnetic Separation: Iridium and Other Metal Nanoparticles
(WILEY-V C H VERLAG GMBHWEINHEIM, 2012)
The immobilization of metal nanoparticles in magnetic responsive solids allows the easy, fast, and clean separation of catalysts; however, the efficiency of this separation process depends on a strong metalsupport interaction. ...
Arrangements of curves and algebraic surfaces
(2008)
A variety is an integral separated scheme of finite type over C. We call it a curve (a surface) if its dimension is one (two). A projective variety is a variety which has a closed embedding into Pn for fome pisitive integer n.
High performance magnetic separation of gold nanoparticles for catalytic oxidation of alcohols
(ROYAL SOC CHEMISTRY, 2010)
We present the magnetic separation approach to facilitate the recovery of gold nanoparticle (AuNP) catalysts. The use of magnetically recoverable supports for the immobilization of AuNPs instead of traditional oxides, ...
Use of chemically modified silica with beta-diketoamine groups for separation of alpha-lactoalbumin from bovine milk whey by affinity chromatography
(Academic Press Inc. Jnl-comp Subscriptions, 2014)
