Post-processing of real-time quantum event measurements for an optimal bandwidth [PDF]

open access: yesScientific Reports, 2023
Single electron tunneling and its transport statistics have been studied for some time using high precision charge detectors. However, this type of detection requires advanced lithography, optimized material systems and low temperatures (mK). A promising

A New Method to Determine Central Wavelength and Optimal Bandwidth for Predicting Plant Nitrogen Uptake in Winter Wheat

open access: yesJournal of Integrative Agriculture, 2013
Plant nitrogen (N) uptake is a good indicator of crop N status. In this study, a new method was designed to determine the central wavelength, optimal bandwidth and vegetation indices for predicting plant N uptake (g N m−2) in winter wheat (Triticum ...

Optimal Scanning Bandwidth Strategy Incorporating Uncertainty about Adversary’s Characteristics

open access: yesEAI Endorsed Transactions on Mobile Communications and Applications, 2014
In this paper, we investigate the problem of designing a spectrum scanning strategy to detect an intelligent Invader who wants to utilize spectrum undetected for his/her unapproved purposes.

Optimal Bandwidth for Multitaper Spectrum Estimation

open access: yesIEEE Signal Processing Letters, 2017
A systematic method for bandwidth parameter selection is desired for Thomson multitaper spectrum estimation. We give a method for determining the optimal bandwidth based on a mean squared error (MSE) criterion. When the true spectrum has a second-order Taylor series expansion, one can express quadratic local bias as a function of the curvature of the ...

Optimal bandwidth allocation in a delay channel [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2006
In this paper, we consider the problem of allocating bandwidth to two queues with arbitrary arrival processes, so as to minimize the total expected packet holding cost over a finite or infinite horizon. Bandwidth is in the form of time slots in a time-division multiple-access schedule.

Optimal Bandwidth Choice for the Regression Discontinuity Estimator [PDF]

open access: yesSSRN Electronic Journal, 2009
We investigate the problem of optimal choice of the smoothing parameter (bandwidth) for the regression discontinuity estimator. We focus on estimation by local linear regression, which was shown to be rate optimal (Porter, 2003).

Optimal spectral bandwidth for long memory [PDF]

open access: yes, 1993
For long range dependent time series with a spectral singularity at frequency zero, a theory for optimal bandwidth choice in non-parametric analysis ofthe singularity was developed by Robinson (1991b).

Time-optimal quantum transformations with bounded bandwidth [PDF]

open access: yesQuantum, 2021
In this paper, we derive sharp lower bounds, also known as quantum speed limits, for the time it takes to transform a quantum system into a state such that an observable assumes its lowest average value.

Fault Detection Based on Multi-Dimensional KDE and Jensen–Shannon Divergence

open access: yesEntropy, 2021
Weak fault signals, high coupling data, and unknown faults commonly exist in fault diagnosis systems, causing low detection and identification performance of fault diagnosis methods based on T2 statistics or cross entropy. This paper proposes a new fault

Optimal transfer functions for bandwidth-limited imaging

open access: yesPhysical Review Research, 2022
One of the fundamental limits of classical optical microscopy is the diffraction limit of optical resolution. It results from the finite bandwidth of the optical transfer function (or OTF) of an optical microscope, which restricts the maximum spatial ...
