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).

Calibrating Dark Energy

, 2008
Exploring the diversity of dark energy dynamics, we discover a calibration relation, a uniform stretching of the amplitude of the equation of state time variation with scale factor. This defines homogeneous families of dark energy physics.

Calibration for Computer Models with Time-Varying Parameter

Mathematics
Traditional calibration methods often assume constant parameters that remain unchanged across input conditions, which can limit predictive accuracy when parameters actually vary.

Financial model calibration using consistency hints [PDF]

, 2001
We introduce a technique for forcing the calibration of a financial model to produce valid parameters. The technique is based on learning from hints. It converts simple curve fitting into genuine calibration, where broad conclusions can be inferred from ...

Split-domain calibration of an ecosystem model using satellite ocean colour data [PDF]

, 2004
The application of satellite ocean colour data to the calibration of plankton ecosystem models for large geographic domains, over which their ideal parameters cannot be assumed to be invariant, is investigated.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Development and Application of External Moving Type Calibration Device for Beam Detector Based on Quasi-impedance Matching Transmission

Yuanzineng kexue jishu, 2022
The beam calibration results are affected by the impedance of the calibration device. If impedance matching is not maintained, reflected signals would be generated, which would lead to the superposition of reflected signals and excitation signals ...

Calibration Challenges for Future Radio Telescopes [PDF]

, 2010
Instruments for radio astronomical observations have come a long way. While the first telescopes were based on very large dishes and 2-antenna interferometers, current instruments consist of dozens of steerable dishes, whereas future instruments will be ...

Standard Errors for Calibrated Parameters

Review of Economic Studies
Abstract 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 ...
