Selective liquid-liquid extraction of mercuric ions by octyl methane sulfonamide
(MARCEL DEKKER INC, 2003)
N-octyl methane sulfonamide (OMSA) has been demonstrated to be a very efficient reagent for selective extraction of Hg(II) ions from aqueous solutions. The extraction bases on rapid reaction of OMSA with Hg(II) ions yielding ...
Chebyshev nets formed by Ricci curves in a 3-dimensional Weyl space
(Elsevier Science BV, 2005)
In this paper Ricci curves in a 3-dimensional Weyl space W-3(g T) are defined and it is shown that any 3-dimensional Chebyshev net formed by the three families of Ricci curves in a W-3(g T) having a definite metric and ...
Support vector regression for surveillance purposes
(SPRINGER-VERLAG BERLIN, 2006)
This paper addresses the problem of applying powerful statistical pattern classification algorithm based on kernel functions to target tracking on surveillance systems. Rather than directly adapting a recognizer we develop ...
Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
(Taylor & Francis Inc, 2002)
An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ...

Metalization of polymer beads via polymer-supported hydrazines as reducing agents
(John Wiley & Sons Inc, 2002)
A new method for depositing metal onto a polymer surface has been developed in which the metal coating of polymer beads is performed with hydrazine functions as reducing agents on the surface of the polymer itself. In this ...
Cosmic ray intensity variation during a CME
(Pergamon-Elsevier Science Ltd, 2002)
The June 6 2000 coronal mass ejection was an exceptional full halo which made it possible to measure cosmic ray (CR) decrease with a simple experimental set-up. Variation in the local secondary cosmic ray density has been ...
Nonuniform sampling for detection of abrupt changes
(BIRKHAUSER BOSTON INC, 2003)
In this work detection of abrupt changes in continuous-time linear stochastic systems and selection of the sampling interval to improve the detection performance are considered. Cost functions are proposed to optimize both ...
Optimal input design for the detection of changes towards unknown hypotheses
(TAYLOR & FRANCIS LTD, 2004)
The effects of auxiliary input signals on detecting changes in ARMAX processes via statistical tests are discussed. Two extensions to the Cumulative Sum Test are considered. The first is applicable when the direction of ...
Pilot-aided Bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
This paper proposes a computationally efficient pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ...
