Calibration for Computer Models with Time-Varying Parameter
MathematicsTraditional calibration methods often assume constant parameters that remain unchanged across input conditions, which can limit predictive accuracy when parameters actually vary.

Parameter regionalization of a monthly water balance model for the conterminous United States [PDF]
Hydrology and Earth System Sciences, 2016 A parameter regionalization scheme to transfer parameter values from gaged to ungaged areas for a monthly water balance model (MWBM) was developed and tested for the conterminous United States (CONUS).

Standard Errors for Calibrated Parameters
Review of Economic StudiesAbstract Calibration, the practice of choosing the parameters of a structural model to match certain empirical moments, can be viewed as minimum distance estimation. Existing standard error formulas for such estimators require a consistent estimate of the correlation structure of the empirical moments, which is often unavailable in ...

PERSONALISED BODY COUNTER CALIBRATION USING ANTHROPOMETRIC PARAMETERS
Radiation Protection Dosimetry, 2015 Current calibration methods for body counting offer personalisation for lung counting predominantly with respect to ratios of body mass and height. Chest wall thickness is used as an intermediate parameter. This work revises and extends these methods using a series of computational phantoms derived from medical imaging data in combination with ...

Calibration and uncertainty issues of a hydrological model (SWAT) applied to West Africa [PDF]
Advances in Geosciences, 2006 Distributed hydrological models like SWAT (Soil and Water Assessment Tool) are often highly over-parameterized, making parameter specification and parameter estimation inevitable steps in model calibration.

Spin-label Order Parameter Calibrations for Slow Motion [PDF]
Applied Magnetic Resonance, 2017 Abstract Calibrations are given to extract orientation order parameters from pseudo-powder electron paramagnetic resonance line shapes of 14N-nitroxide spin labels undergoing slow rotational diffusion. The nitroxide z-axis is assumed parallel to the long molecular axis.

Simultaneous Parameter Calibration, Localization, and Mapping [PDF]
Advanced Robotics, 2012 Abstract The calibration parameters of a mobile robot play a substantial role in navigation tasks. Often these parameters are subject to variations that depend either on changes in the environment or on the load of the robot. In this paper, we propose an approach to simultaneously estimate a map of the environment, the position of the on-board sensors ...
