Parametric direction-of-arrival estimation with three recurrence relations of spherical harmonics.

Journal of the Acoustical Society of America, 2019
The eigenbeam estimation of signal parameters via the rotational invariance technique (EB-ESPRIT) is a well-known subspace-based beamforming algorithm for a spherical microphone array. EB-ESPRIT uses a recurrence relation to directly estimate directional

Recurrence Relations

2016
In the upcoming chapter we introduce recurrence relations. These are equations that define in recursive fashion, via suitable functions, the terms appearing in a real or complex sequence. The first section deals with some well-known examples that show how these relations may arise in real life, e.g., the Lucas Tower game problem or the death or life ...

Recurrence relations and determinant forms for general polynomial sequences. Application to Genocchi polynomials

Integral transforms and special functions, 2018
In this paper the set of general polynomial sequences is considered. An elementary systematic approach is proposed. In fact a structure of group is given and for every element of this group recurrence relations and determinant forms are derived ...

Perturbed Recurrence Relations

Numerical Algorithms, 2003
The authors give some new relations between two families of polynomials defined by a three-term recurrence relation. They give a new method to study the behaviour of such polynomials. This method allows to solve the problem of losing information in the case of large perturbations since it gives the explicit representation of a perturbed family of ...

Civil–Military Relations and Civil War Recurrence: Security Forces in Postwar Politics

Journal of Conflict Resolution, 2020
Does restructuring security forces reduce the risk of civil war recurrence? Prior research has examined effects of military integration in alleviating commitment problems, but the evidence has been inconclusive.

On Certain Recurrence Relations

Mathematische Nachrichten, 1970
AbstractIn this paper first we establish six recurrence relations for the H‐function with the help of certain formulae concerning generalized BESSEL function. Later on, we obtain recurrence relations for MEIJER'S G‐function, GAUSS'S hypergeometric function and BESSEL function.

High-order recurrence relations, Hermite-Padé approximation and Nikishin systems

, 2016
The study of sequences of polynomials satisfying high-order recurrence relations is connected with the asymptotic behaviour of multiple orthogonal polynomials, the convergence properties of type II Hermite-Padé approximation and eigenvalue distribution ...

Drug-related recurrent meningitis

Journal of Infection, 1988
A 56-year-old man presented with recurrent smear and culture-negative meningitis having ingested Ibuprofen before each episode. The association between Ibuprofen and meningitis has been well established in systemic lupus erythematosus but has been reported only rarely in previously healthy patients.
