Particle filtering with alpha-stable distributions [PDF]

open access: yes, 2005
In this paper we introduce a novel sequential Monte Carlo technique, which is based on the family of symmetric alpha- stable (SAS) distributions.

The distribution of ascents of size $d$ or more in samples of geometric random variables [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We consider words or strings of characters $a_1a_2a_3 \ldots a_n$ of length $n$, where the letters $a_i \in \mathbb{Z}$ are independently generated with a geometric probability $\mathbb{P} \{ X=k \} = pq^{k-1}$ where $p+q=1$.

Potential Ecological Distributions of Urban Adapters and Urban Exploiters for the Sustainability of the Urban Bird Network

open access: yesISPRS International Journal of Geo-Information, 2022
The bird community in urban areas indicates the species-specific adaptability to urban conditions such as the increase in man-made habitats. Urban adapters and urban exploiters, two groups that make up most of the urban birds, were assessed to determine ...

Pattern of common hormonal disorders among patients with polycystic ovarian syndrome at a tertiary health facility in Nigeria

open access: yesNigerian Journal of Medicine, 2022
Background: Polycystic ovarian syndrome (PCOS) is a disease associated with multiple reproductive and metabolic endocrine disorders. It is associated with cardiometabolic complications with established morbidity and mortality. Aim: We studied the pattern

EXPONENTIAL GENERALIZED DISTRIBUTIONS [PDF]

open access: yes, 2010
In this paper we generalize the Fourier transform from the space of tempered distributions to a bigger space called exponential generalized distributions.

Singular random matrix decompositions: distributions. [PDF]

open access: yes, 2002
Assuming that Y has a singular matrix variate elliptically contoured distribution with respect to the Hausdorff measure, the distributions of several matrices associated to QR, modified QR, SV and Polar decompositions of matrix Y are determined, for ...

Analysis of pediatric fixation equipment with audio-video for chest radiography examinations

open access: yesJurnal Ilmiah SINERGI
Pediatric patients are generally uncooperative during radiology examinations. Radiographic images can become blurry due to movement. This will cause to repeat examinations, thereby significantly increasing radiation exposure, and it can pose significant ...

Complex and distributional weights for sieved ultraspherical polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Contour integral and distributional orthogonality of sieved ultraspherical polynomials are established for values of the parameters outside the natural range of orthogonality by positive measures on the real line.
