Experimental investigation of transform ratio ternary phase-amplitude filters for improved correlation discrimination

Optical Engineering, 1990
Transform ratio ternary phase-amplitude filters (TR-TPAFs) encoding the modulation states 1, 0, — 1 have been investigated in theory and practice. Simulations have demonstrated that TR-TPAFs can be formulated to provide increased discrimination compared with binary phase-only filters.

Label free electrochemical DNA hybridization discrimination effects at the binary and ternary mixed monolayers of single stranded DNA/diluent/s in presence of cationic intercalators

Biosensors and Bioelectronics, 2008
Electrochemical label free DNA hybridization discrimination of the brain tumor sequence CK20 has been made at the gold-thiol and thiol diluent binary and ternary mixed monolayer interfaces in presence of the [Fe(CN)6](3-) and double stranded DNA (dsDNA) specific cationic intercalators, proflavine (PF) and methylene blue (MB), respectively. Thiol hexane

Investigating the discrimination potential of linear and nonlinear spectral multivariate calibrations for analysis of phenolic compounds in their binary and ternary mixtures and calculation pKa values

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2016
Vanillin (VA), vanillic acid (VAI) and syringaldehyde (SIA) are important food additives as flavor enhancers. The current study for the first time is devote to the application of partial least square (PLS-1), partial robust M-regression (PRM) and feed forward neural networks (FFNNs) as linear and nonlinear chemometric methods for the simultaneous ...

An Attempt to Discriminate between the Hydrophobic and Aromatic π−π Interactions in the Copper(II) Ternary Complexes CuLA with L = 1,10-Phenanthroline or 2,2‘-Bipyridyl and A =para-X-Substituted Phenylalaninates

Inorganic Chemistry, 2007
For the title complexes, the value of formation constant K(CuL+A) is higher than that of K1(CuA2). According to the mechanistic consideration, log K(CuL+A) is calculated for regular Cu(II) complexes with neither special enhancement nor diminution of the stability constant.

Chiral metal complexes 44. Enantiomeric discrimination in ternary cobalt(III) complexes of N,N′-dimethyl-N,N′-di(2-picolyl)-1S,2S-diaminocyclohexane and α-amino acids; including the crystal structure of the S-prolinato complex

Inorganica Chimica Acta, 1995
Abstract When the C2-symmetrical complex Λ-α[Co(S,S-picchxcMe2Cl2]+ (S,S-picchxnMe2 is N,N′-dimethyl-N,N′-di(2-picolyl)-1S,2S-diaminocyclohexane) is reacted with the α-amino acids proline (proH), alanine (alaH) or 2-amino-2-methylpropandioic acid (AMMAH2), the two chloride ions are replaced by the O,N-bidentates with retention of configuration at the

Case study of binary and ternary synthetic discriminant function filters with similar in-class and out-of-class images

Optical Engineering, 1993
We compare computer simulation results of optical correlator performance using synthetic discriminantfunction filters encoded in binary phase versus ternary phase and amplitude for distortion-tolerant pattern recognition. We examine two different ternary filter formulations designed to enhance discrimination and SNR. The simulated situation is for very

A reevaluation of tectonic discrimination diagrams and a new probabilistic approach using large geochemical databases: Moving beyond binary and ternary plots

Journal of Geophysical Research: Solid Earth, 2006
Statistically rigorous confidence intervals calculated from analyses of basaltic volcanic samples obtained from two large geochemical databases (PetDB and GEOROC) demonstrate that published binary and ternary discrimination diagrams seldom correctly classify samples from mid‐ocean ridges, island arcs, and ocean islands with better than 60% accuracy ...
