On the Selection of the Bandwidth Parameter for the k‐Chart

Quality and Reliability Engineering International, 2017
The k‐chart, based on support vector data description, has received recent attention in the literature. We review four different methods for choosing the bandwidth parameter, s, when the k‐chart is designed using the Gaussian kernel. We provide results of extensive Phase I and Phase II simulation studies varying the method of choosing the bandwidth ...

Spectral bandwidth correction with optimal parameters based on deep learning

Applied Optics, 2021
Spectral bandwidth correction is an effective way to obtain the original spectrum. However, the correct selection of optimal parameters used to recover the distortion spectrum in bandwidth correction algorithms has always been an important problem. To overcome the shortcomings of traditional parameter selection methods and obtain the optimal parameter,

Adjustment of piezoelectric transducer parameters for bandwidth enhancement

Ultrasonics, 1985
Abstract The enhancement of the efficiency bandwidth for ultrasonic transducers used in echographic applications is investigated. Analytical and experimental results are given which show the availability of simple conditions on the mechanical impedance ratio and the radiation resistance for the design of broadband transducers.

Gain Bandwidth Properties of a Distributed Parameter Load

IEEE Transactions on Circuit Theory, 1968
The gain bandwidth restrictions are considered for a distributed parameter load consisting of a resistor shunted by an open-circuited stub of delay length \tau . An aperiodic solution for the optimum flat gain response in the frequency domain is obtained by using a computer, solution, which solves the infinite set of simultaneous constraint equations ...

The effects of the physical parameters on the bandwidth of a folded dipole

IRE Transactions on Antennas and Propagation, 1958
An expression is derived which yields the feedpoint admittance of a folded unipole or dipole at any desired frequency. This expression shows that the input admittance is composed of two parts-a radiation part and a transmission line part. The radiation part is analyzed as a vertical radiator while the transmission line part is analyzed by transmission ...

Measurement of the Apparent Bandwidth Parameters of an Absorption Band

Applied Spectroscopy, 1968
It is quite well known that an absorption spectrum, either recorded or point-point measured, is usually represented graphically as a percentage transmission or absorption vs wavenumber or wavelength.1 For such an absorption band, the baseline1 is carefully selected.

Bandwidth Conversion of ELF Noise Parameters

IEEE Transactions on Communications, 1984
The Field-Lewinstein-Modestino model represents ELF noise as the sum of Gaussian and impulsive components. This model has proven to be accurate and is especially convenient for analysis and simulation. However, the parameters of the model are bandwidth dependent and have been measured for only a few specific bandwidths.
