Statistical Calibration Theory
<p>A calibration method substitutes for measurements, X(,i), that are accurate but impractical or costly, a set of measurements, Y(,i), that are less accurate but simpler or less costly. There are two general types of calibration methods. The classical approach in which once the calibration sample …

Robust remote measurement calibration
The objective of Remote Measurements Calibration (RMC) method is to minimize systematic errors through an appropriate scaling procedure. A new method for RMC has been developed. This method solves the problems of observability, multiplicity of solutions, and ambiguity of reference points associated …

Thermal emission measurement and calibration
This thesis details a measurement setup and experimental procedures for emittance measurements using a Fourier transform infrared spectrometer. We calibrate the FTIR measurement system using measurements of a blackbody source at two temperatures to obtain the true emittance and absolute spectral …

Some results in non-parametric calibration
In statistical terminology, calibration is the problem of recovering the value of the control variable when the value of the response is given. Mathematically, it is the problem of determining the values ofthe independent variables that respond to a given function value: in other words, the problem …

Bone Density Measurement via Radiographic Calibration
… bone density (bone OD) via complex radiographic calibration. By developing a brightness/darkness index (BDI), the greyscale of radiographs, calibrated with an aluminum marker of varying known thickness, can be compared to the average density of a cross-section of bone. At varying radiographic …

Item parameter drift and online calibration
… testing. This paper introduces an online (re)calibration design to detect item parameter drift for computerized adaptive testings in both unidimensional and multidimensional environment. Specifically, for online calibra- tion optimal design in unidimensional computerized adaptive testing …

Depth camera calibration using depth measurements
… the depth images - and then use them for calibration. Previous work to calibrate the depth cameras involves either using a multiple camera set-up or using an extremely precise optical measurement rack to move checker-board images in the camera’s field of view. However, we want average …

Deep Calibration of Option Pricing Models
This dissertation investigates the calibration efficiency of short rate models using deep neural networks. The main focus is on the calibration of one-and-two factor Hull-White models to caplets and swaptions data, where the inputs are interest rate derivative prices or implied volatilities, and …

Ultraviolet laser calibration of drift chambers
… use of a focused ultraviolet laser as a track calibration source in drift chambers, and specifically in a small time projection chamber (TPC). Drift chambers such as TPCs reconstruct the trajectories of charged particles by amplifying and collecting electrons produced by ionization of gas atoms …

Simultaneous sensor calibration and path estimation
… presents two topics related to the simultaneous calibration of a network of imaging sensors, i.e. cameras, and the recovery of the trajectory of an object moving among those sensors. The non-overlapping fields of view for the cameras do not cover the entire scene, and therefore there are time …

Calibration of a microscopic traffic simulator
A systematic calibration study was performed on a microscopic traffic simulator- MITSIM. An optimization based framework was developed for calibration. Car- Following model parameters were identified for calibration and experimental design methodology was used to determine the set of sensitive …

Calibration of time domain network analyzers
A calibration technique for time domain reflectometry and transmission (TDR and TDT) measurement system as applied to network analysis is presented. The calibration corrects for the errors caused by the response of the measurement system. A complete physically-based model has been established for …
