A new method for estimating multi-source water supply considering joint probability distributions under uncertainty

open access: yesFrontiers in Earth Science, 2023
A new method integrating techniques of copula and interval estimation to estimate multi-source water supply was proposed. Using the copula theory, joint probability distributions of multiple water sources were constructed for the estimation of water ...

Statistics of the MLE and Approximate Upper and Lower Bounds - Part 1: Application to TOA Estimation [PDF]

open access: yes, 2014
In nonlinear deterministic parameter estimation, the maximum likelihood estimator (MLE) is unable to attain the Cramer-Rao lower bound at low and medium signal-to-noise ratios (SNR) due the threshold and ambiguity phenomena.

Confidence Intervals for the Long-Term Noise Indicators Using the Kernel Density Estimator

open access: yesArchives of Acoustics, 2016
A non-classical model of interval estimation based on the kernel density estimator is presented in this paper. This model has been compared with interval estimation algorithms of the classical (parametric) statistics assuming that the standard deviation ...

INTERVAL ESTIMATION OF THE VOLUMES OF RESOURCE CONSUMPTION AT THE STOCHASTIC BASIC DATA

open access: yesВестник университета, 2018
The method of interval estimation of resource consumption volumes is considered with the random nature of a multitude of random factors. The necessity of taking into account errors in the values of functions and arguments when estimating the parameters ...

Interval estimation of trigonometrical splines [PDF]

open access: yesMATEC Web of Conferences, 2019
Quite often, it is necessary to quickly determine variation range of the function. If the function values are known at some points, then it is easy to construct the local spline approximation of this function and use the interval analysis rules.

Mapping the origins of time: Scalar errors in infant time estimation [PDF]

open access: yes, 2014
Time is central to any understanding of the world. In adults, estimation errors grow linearly with the length of the interval, much faster than would be expected of a clock-like mechanism.

Parameter Estimation in a Noisy 1D Environment via Two Absorbing Receivers

open access: yes, 2020
This paper investigates the estimation of different parameters, e.g., propagation distance and flow velocity, by utilizing two fully-absorbing receivers (RXs) in a one-dimensional (1D) environment. The time-varying number of absorbed molecules at each RX

Reduced-Order and Full-Order Interval Observers Design for Discrete-Time System

open access: yesIEEE Access, 2020
In this paper, the design of reduced-order and full-order interval observers for discrete-time system is investigated. First, the original system is transformed into a descriptor system with the ability to estimate the unknown noise of sensors.
