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

Journal 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 Bandwidth for Multitaper Spectrum Estimation
IEEE 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]
IEEE 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.

Time-optimal quantum transformations with bounded bandwidth [PDF]
Quantum, 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
Entropy, 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
Physical 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 ...

Bandwidth-Optimal Random Shuffling for GPUs [PDF]
ACM Transactions on Parallel Computing, 2022 Linear-time algorithms that are traditionally used to shuffle data on CPUs, such as the method of Fisher-Yates, are not well suited to implementation on GPUs due to inherent sequential dependencies, and existing parallel shuffling algorithms are unsuitable for GPU architectures because they incur a large number of read/write operations to high latency ...

The Optimal Bandwidth Parameter Selection in GPH Estimation
Journal of Mathematics, 2021 In this paper, the optimal bandwidth parameter is investigated in the GPH algorithm. Firstly, combining with the stylized facts of financial time series, we generate long memory sequences by using the ARFIMA (1, d, 1) process.
