Estimation of Vehicle Dynamic Parameters Based on the Two-Stage Estimation Method [PDF]

open access: yesSensors, 2021
Vehicle dynamic parameters are of vital importance to establish feasible vehicle models which are used to provide active controls and automated driving control. However, most vehicle dynamics parameters are difficult to obtain directly.

A simple two-stage carrier-phase estimation algorithm for 32-QAM coherent optical communication systems [PDF]

open access: goldFrontiers in Physics
The combination of high-order modulation formats and linewidth-tolerant carrier phase estimation (CPE) can effectively improve spectrum efficiency and relax the limitation of laser linewidth.

Power Families of Bivariate Proportional Hazard Models

open access: yesMathematics, 2022
In this paper, we propose a general class of bivariate proportional hazard distributions, which is based on the family of asymmetric proportional hazard distributions and the bivariate Pareto copula.

TWO-STAGE DEA ESTIMATION OF TECHNICAL EFFICIENCY: COMPARISON OF DIFFERENT ESTIMATORS [PDF]

open access: yesReview of Agricultural and Applied Economics, 2022
Research background: The challenge of resource limitations requires that farmers make judicious use of resources to maximize output and profit levels. This can be achieved through assessment of resource-use efficiency of farmers by estimating the level ...

An Exponentiated Multivariate Extension for the Birnbaum-Saunders Log-Linear Model

open access: yesMathematics, 2022
In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the maximum
