SAR Images Statistical Modeling and Classification Based on the Mixture of Alpha-Stable Distributions

open access: yesRemote Sensing, 2013
This paper proposes the mixture of Alpha-stable (MAS) distributions for modeling statistical property of Synthetic Aperture Radar (SAR) images in a supervised Markovian classification algorithm.

Evaluating the impact of immunization with the “pan-fungal” vaccine, NXT-2, on the gut mycobiome and microbiome in non-human primates (NHPs) [PDF]

open access: yesMicrobiology Spectrum
Fungal infections remain a significant public health concern with high mortality, morbidity, and increasing associated health costs. This burden is projected to rise due to expansion of at-risk populations, limited therapeutics, increasing drug ...

Spatiotemporal dynamics of soil bacterial and fungal communities at a small scale [PDF]

open access: yesFrontiers in Microbiology
BackgroundSoil is a common form of trace evidence in forensic investigations, and its indigenous microbial communities hold promise for geographic provenance determination. However, most existing studies focus on macro-scale soil microbial patterns, with

Alpha-Stable Autoregressive Modeling of Chua's Circuit in the Presence of Heavy-Tailed Noise

open access: yesChaos Theory and Applications, 2023
This study presents alpha-stable autoregressive (AR) modeling of the dynamics of Chua's circuit in the presence of heavy-tailed noise. The parameters of the AR time series are estimated using the covariation-based Yule-Walker method, and the parameters ...

Stochastic Geometry-Based Analysis of the Impact of Underlying Uncorrelated IoT Networks on LoRa Coverage

open access: yesIEEE Access, 2022
IoT networks are more and more present nowadays. Some IoT protocols share the same bandwidth leading to interference on neighboring networks and decrease of overall coverage.

Constructing portfolios using stable distributions: The case of S&P 500 sectors exchange-traded funds

open access: yesMachine Learning with Applications, 2022
Portfolio construction is an important practical problem in finance. In the traditional approach, introduced by Markowitz, one assumes normally distributed returns and constructs a portfolio with a minimum risk (measured by the standard deviation of ...

libstable: Fast, Parallel, and High-Precision Computation of α-Stable Distributions in R, C/C++, and MATLAB

open access: yesJournal of Statistical Software, 2017
α-stable distributions are a family of well-known probability distributions. However, the lack of closed analytical expressions hinders their application. Currently, several tools have been developed to numerically evaluate their density and distribution

A Hybrid Model to Simulate Test Cases of Electrical Power Systems

open access: yesApplied Sciences, 2020
The development of solution algorithms for power system problems is based on hypothetical test systems and test cases. These systems are very scarce, and the degree of variability is relatively low.

Selected Applications of Scale Spaces in Microscopic Image Analysis

open access: yesCybernetics and Information Technologies, 2015
Image segmentation methods can be classified broadly into two classes: intensity-based and geometry-based. Edge detection is the base of many geometry-based segmentation approaches.
