Space-Time Modeling of Rainfall Rate for Satellite Networks

IEEE Access, 2020
A new comprehensive space-time model for the characterization of point rainfall rate is presented. A detailed assessment of four key rain characteristics (probability of rain/no rain condition, first and second order lognormal statistics and, space and ...

Performance Evaluation of UWB Massive MIMO Channels With Favorable Propagation Features

IEEE Access, 2019
Radio wave propagation can be characterized by two major sets: empirical and deterministic models. Empirical models rely on the received signals' statistics and thus offer lower precision.

Detecting spatial patterns with the cumulant function – Part 1: The theory [PDF]

Nonlinear Processes in Geophysics, 2008
In climate studies, detecting spatial patterns that largely deviate from the sample mean still remains a statistical challenge. Although a Principal Component Analysis (PCA), or equivalently a Empirical Orthogonal Functions (EOF) decomposition, is often

Perception of Justice and Political Participation: Graduate Students’ Perception of the Distribution and Redistribution Policies of Raiesi Administration and Their Impact on Political Participation [PDF]

دولت‌پژوهی
Extended Abstract Introduction If the political system is viewed as a system with both outputs and inputs (Almond & Powell, 2005), it becomes clear that the inputs and data within this system strongly influence one another.

Parametric Inference for a Multicomponent Stress–Strength Reliability Model With Kumaraswamy Distribution Under Ordered Ranked Set Sampling

Journal of Mathematics
Assessing reliability in systems with dual stress constraints needs a flexible model and effective sampling methods. A framework using the Kumaraswamy distribution is set up for multicomponent stress and strength systems.

A Heavy-Tailed QLindley Distribution for Modelling Skewed Lifetime Data

Mathematics
Lifetime data arising in engineering reliability, survival analysis, actuarial science, and environmental studies often exhibit substantial right-skewness, extreme observations, and heterogeneous hazard-rate structures.
