Extended Target Marginal Distribution Poisson Multi-Bernoulli Mixture Filter [PDF]

open access: yesSensors, 2020
The existence of clutter, unknown measurement sources, unknown number of targets, and undetected probability are problems for multi-extended target tracking, to address these problems; this paper proposes a gamma-Gaussian-inverse Wishart (GGIW ...

Tomographic Description of a Quantum Wave Packet in an Accelerated Frame

open access: yesEntropy, 2021
The tomography of a single quantum particle (i.e., a quantum wave packet) in an accelerated frame is studied. We write the Schrödinger equation in a moving reference frame in which acceleration is uniform in space and an arbitrary function of time. Then,

Some Theoretical and Computational Aspects of the Truncated Multivariate Skew-Normal/Independent Distributions

open access: yesMathematics, 2023
In this article, we derive a closed-form expression for computing the probabilities of p-dimensional rectangles by means of a multivariate skew-normal distribution.

Some Statistical Aspects of the Truncated Multivariate Skew-t Distribution

open access: yesMathematics, 2022
The multivariate skew-t distribution plays an important role in statistics since it combines skewness with heavy tails, a very common feature in real-world data.

Spatial Copula Model for Imputing Traffic Flow Data from Remote Microwave Sensors

open access: yesSensors, 2017
Issues of missing data have become increasingly serious with the rapid increase in usage of traffic sensors. Analyses of the Beijing ring expressway have showed that up to 50% of microwave sensors pose missing values.

Selection of the Best Copula Function in Bivariate Analysis of Water Resources Components (Case study: Siminehrood River Basin, Iran) [PDF]

open access: yesWater Harvesting Research
The copula function is a joint distribution of correlated random variables that are defined based on univariate marginal distributions. The aim of the present study is to select the best copula function to create joint probability distributions between ...
