Vine variety discrimination with airborne imaging spectroscopy
SPIE Proceedings, 2007We aim at the discrimination of varieties within a single plant species (Vitis vinifera) by means of airborne hyperspectral imagery collected using a CASI-2 sensor and supervised classification, both under constant and varying within-scene illumination conditions.

Projective Dual Varieties and General Discriminants
1994We denote by P n the standard complex projective space of dimension n. Thus a point of P n is given by (n + 1) homogeneous coordinates (x 0:...: x n ), x i ∈ C, which are not all equal to 0 and are regarded modulo simultaneous multiplication by a non-zero number.

Discriminant varieties and discriminant ideals for operator vessels in Banach space
Integral Equations and Operator Theory, 1995A multivariate analogue of the theory of characteristic functions (for single linear operators) was advocated for several decades by M. S. Livšic and his school. In particular he has created the notion of a commutative operator vessel, which indeed encodes the expected features of a characteristic function for commutative \(n\)-tuples of Hilbert space ...

Rich countable epimorphism skeletons of discriminator varieties
Siberian Mathematical Journal, 1991More or less completing his results from previous papers, the author shows that a discriminator variety \({\mathfrak M}\) which is not finitely generated but either has finite signature or has singleton subalgebras of all its algebras is universal for countable quasiordered sets S, i.e.

Countable skeletons of finitely generated discriminator varieties
Siberian Mathematical Journal, 1992It has been proved in our earlier papers [Algebra Logika 28, No. 5, 597- 607 (1989; Zbl 0708.08005); Sib. Mat. Zh. 31, No. 3, 125-134 (1990; Zbl 0712.08008)] that 1) if \({\mathfrak M}\) is a discriminator variety that is not finitely generated, then \(\langle {\mathfrak {JM}}_{\aleph_ 0};\ll\rangle\), its countable epimorphism skeleton, contains an ...
