Calibration as parameter estimation in sensor networks

Proceedings of the 1st ACM international workshop on Wireless sensor networks and applications, 2002
We describe an ad-hoc localization system for sensor networks and explain why traditional calibration methods are inadequate for this system. Building upon previous work, we frame calibration as a parameter estimation problem; we parameterize each device and choose the values of those parameters that optimize the overall system performance. This method

Calibrating Parameters of Cost Functionals

2000
We 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.

Determination of Spectrometer-Detector Parameters from Calibration Spectra and the Use of the Parameters in Spectrometer Calibrations

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.

Electric Parameters and Calibration of Accelerometers

Seismic Instruments, 2019
The 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.

Identification and calibration of the geometric parameters of robots

1990
This paper presents a general method to identify the geometric parameters of serial robots. The robot location and the tool location parameters are taken into account. Experimental results are applied on a six degree of freedom robot of cylindrical type.

Calibration of GA Parameters

1999
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 ...

Learning spectral calibration parameters for color inspection

Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002
Light sensor spectral calibration is an ill-defined problem. For the identification problem one needs a priori knowledge of the characteristics of the sensor which is difficult to get in most situations. A new methodology is presented in this paper that does not rely on any a priori knowledge of the sensor's characteristics. The method uses an extended

The effects of experimental parameters and calibration on MTDSC data

International Journal of Pharmaceutics, 1999
To produce accurate and artefact-free MTDSC data it is necessary to choose suitable experimental parameters (i.e. modulation period, temperature amplitude, sample mass and pan type). A poor choice of parameters can result in distortion of the modulation and inaccurate heat capacity data and can also affect the result of the deconvolution procedure ...

Simultaneous Zonation and Calibration of Pipe Network Parameters

Journal of Hydraulic Engineering, 2003
A procedure for simultaneously zoning and calibrating pipe network parameters is proposed and applied to the determination of pipe resistance coefficients. The methodology is aimed at grouping the parameters of all the pipes into a small number of zone parameters, constrained to keep the difference between the computed and the measured water heads ...

Parameter calibration and inadequacy modeling in a computer experiment

Quality and Reliability Engineering International, 2011
AbstractDeterministic simulation is a popular tool used to numerically solve complex mathematical models in engineering applications. These models often involve parameters in the form of numerical values that can be calibrated when real‐life observations are available.
