A Third Order Point Process Characteristic

Scandinavian Journal of Statistics, 1998
Second order characteristics, in particular Ripley's K‐function, are widely used for the statistical analysis of point patterns. We examine a third order analogue, namely the mean number T(r) of r‐close triples of points per unit area. Equivalently this is the expected number of r‐close point pairs in an r‐neighbourhood of the typical point.

Tracking by Third-Order Tensor Representation

IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2011
This paper proposes a robust tracking algorithm by third-order tensor representation and adaptive appearance modeling. In this method, the target in each video frame is represented by a third-order tensor. This representation preserves the spatial correlation inside the target region and can integrate multiple appearance cues for target description ...

Information and third order ontology

Biosystems, 1998
The question of 'a unified theory of information' is addressed from the logical position of many-valued ontologies. Information is described as an operational factor which forms a trans-contextural bridge between disjunct ontological systems (or monocontextures).

Isospectral Flows of Third Order Operators

SIAM Journal on Mathematical Analysis, 2001
Summary: The author considers the third-order linear differential operator \(L_{p,q}=i\frac{d^3}{dx^3}+i\frac{d}{dx}q+iq\frac{d}{dx}+p\) on the unit interval. The associated boundary conditions are \(y(0)=y(1)=0\), \(y'(0)=zy'(1)\) with \(z\in{\mathbb C}\), \(|z|=1\). For all but a finite number of parameters \(z\), the eigenvalues \(\lambda_{j}\) of \(

Spectral Approximation of Third-Order Problems

Journal of Scientific Computing, 1999
The author introduces a Chebyshev collocation method for the partial differential equation \(u_t = u_{xxx}\) on the set \((x, t) \in (-1, 1) \times (0, T]\). The boundary conditions are of a Dirichlet sort which ensure stability. A computational investigation suggests that collocation at the Gauss-Lobatto points produces a stable numerical method.

Relations in Monadic Third-Order Logic

Journal of Philosophical Logic, 1997
In der monadischen Logik der dritten Stufe (verkürzt: M3oL) kommen als gebundene Variablen nur Individuen, einstellige Prädikate der ersten Stufe und solche einstelligen Prädikate der zweiten Stufe vor, für welche als Argumente die einstelligen Prädikate der ersten Stufe auftreten. Der Verf.

Theory of Third‐Order Nonlinear Photoconductivity and Third‐Order Photogalvanic Effect in Glass

physica status solidi (b), 1995
AbstractThe general theory of a third‐order generalized photoconductivity in glass is developed using a density matrix approach in the generalized master equation approximation. The theory is applied to third‐order photogalvanic effect in glass in connection with photoinduced second‐harmonic generation in silica.

Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials and their properties

Asian-European Journal of Mathematics, 2020
In this paper, the Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials are defined. Then Binet formula and generating functions of these numbers are given. Also, some summation identities for Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials are obtained by using the recurrence ...

Third Order Design

1985
The third order design (THOD) has been defined as the problem of improving, extending or densifying an existing network in an optimal way by introducing additional points and/or additional observations. Two generally different problems are coming up in the THOD: The one is the optimal improvement of the network the other is the optimal design of a ...
