On a Multiple Hilbert's Inequality with Parameters [PDF]

open access: yesJournal of Inequalities and Applications, 2010
The author considers certain multiple Hilbert type inequalities with parameters and weight coefficients. Some of the theorems extend earlier published results. One of the methods of the paper relies on the application of the classical Hadamard integral inequalities. A constant factor appearing in one of the inequalities is best possible.

A Reverse Hardy–Hilbert’s Inequality Containing Multiple Parameters and One Partial Sum

open access: yesMathematics, 2022
In this work, by introducing multiple parameters and utilizing the Euler–Maclaurin summation formula and Abel’s partial summation formula, we first establish a reverse Hardy–Hilbert’s inequality containing one partial sum as the terms of double series ...

Global Gridded Argo Dataset Based on Gradient-Dependent Optimal Interpolation

open access: yesJournal of Marine Science and Engineering, 2022
The international Argo Program was launched at the turn of the millennium. It has since collected over 2 million vertical profiles of temperature and salinity from the upper 2000 m of the global ocean.

Multiple description quantization of sinusoidal parameters [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
A new scheme for sinusoidal audio coding named multiple description spherical trellis-coded quantization is proposed and analytic expressions for the point densities and expected distortion of the quantizers are derived based on a high-resolution assumption. The proposed quantizers are of variable dimension, i.e., sinusoids can be quantized jointly for

Statistical Resolution Limit for multiple parameters of interest and for multiple signals [PDF]

open access: yes2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
The concept of Statistical Resolution Limit (SRL), which is defined as the minimal separation to resolve two closely spaced signals, is an important tool to quantify performance in parametric estimation problems. This paper generalizes the SRL based on the Cram'er-Rao bound to multiple parameters of interest per signal and for multiple signals.
