Calibration Strategy for Urban Catchment Parameters
Journal of Hydraulic Engineering, 1992A simple and methodical strategy is presented for estimating the parameters of a catchment. The method makes use of rainfall‐runoff records to construct response surfaces of the peak flow in terms of eight calibration parameters. The eight calibration parameters are assumed to vary between certain physically meaningful limits and to be random and ...

Joint estimation of array calibration parameters
Proceedings. 2005 International Conference on Communications, Circuits and Systems, 2005., 2005Performance of array processing is severely impaired in the presence of mutual coupling and channel mismatch among sensors. In this paper, a novel method is proposed to solve the problem which is suitable for arbitrary arrays. In the proposed method, only one auxiliary signal source is used to transmit from different directions in different time, and ...

This chapter focuses on a critical dilemma faced in many GA applications: the optimum selection of the different GA parameters to ensure the GA’s rapid convergence—both on-line and off-line (Section 2.9). We address this task early in this text because the satisfactory resolution of it can either make or break the efficacy of the GA, for there is no ...

Calibrating Input Parameters via Eligibility Sets
2020 Winter Simulation Conference (WSC), 2020Reliable simulation analysis requires accurately calibrating input model parameters. While there has been a sizable literature on parameter calibration that utilizes directly observed data, much less attention has been paid to the situation where only output-level data are available to justify input parameter choices.

Calibrating Parameters of Cost Functionals
2000We propose a new framework for calibrating parameters of energy functionals, as used in image analysis. The method learns parameters from a family of correct examples, and given a probabilistic construct for generating wrong examples from correct ones.

Parameter Calibrations on MOSFET Stress Sensors
Journal of Electronic Packaging, 2012Due to the carrier mobility changes with the mechanical loading and its small size, the MOSFET (metal-oxide-semiconductor field-effective-transistor) has the potential to be a suitable chip stress monitoring tool for microelectronic packaging. In this work, a complete and accurate approach to calibrate the coefficients for both types of MOSFET stress ...

Applied Spectroscopy, 2004
The grating equation is used to generate quadratic calibration equations for multichannel detectors with perpendicular and tilted focal planes. The quadratic coefficients are not independent and contain terms that are used to solve for spectrometer-detector parameters. The parameters can be calculated from a quadratic fit at one spectrometer position,

Calibration of fission track dating parameters
Nuclear Track Detection, 1977Abstract A comparison of fission track and K-Ar ages for a set of mineral age standards has been used to evaluate the 238U spontaneous fission decay constant, 238λf. Neutron doses were monitored with two fission-track glasses calibrated against a series of Co wire neutron flux monitors in an irradiation facility with a uniform flux distribution in ...

Improved Free-Space S-Parameter Calibration
2005 IEEE Instrumentationand Measurement Technology Conference Proceedings, 2006An improved method for performing a full two-port s-parameter calibration in free-space is presented. The proposed calibration technique computes the error coefficients from measurements made on an empty fixture and a measurement made on a metal plate of known thickness. Time-domain gating was employed.

Electric Parameters and Calibration of Accelerometers
Seismic Instruments, 2019The paper describes the operating principle of piezoelectric accelerometers and methods for determining their conversion factor in the time and frequency domains; the methods involve comparing simultaneous recordings of an accelerometer, a displacement sensor, a velocimeter, and a calibration shaker table.
