On-Wafer Calibration Algorithm for Partially Leaky Multiport Vector Network Analyzers [PDF]

, 2005
A new solution for multiport vector network analyzer calibration is presented in this paper. The error model is divided in two separate leaky halves, each of them with crosstalk terms, but without the leakage between the two sides.

Making virtual species less virtual by reverse engineering of spatiotemporal ecological models

Methods in Ecology and Evolution, 2023
The virtual species (VS) and virtual ecologist (VE) approaches are useful tools that allow testing different methodological aspects of species distribution modelling.

Optimal Transport for Model Calibration [PDF]

SSRN Electronic Journal, 2021
We provide a survey of recent results on model calibration by Optimal Transport. We present the general framework and then discuss the calibration of local, and local-stochastic, volatility models to European options, the joint VIX/SPX calibration problem as well as calibration to some path-dependent options.

Automatic planning for machine tool calibration: A case study [PDF]

, 2012
Machine tool owners require knowledge of their machine’s capabilities, and the emphasis increases with areas of high accuracy manufacturing. An aspect of a machine’s capability is its geometric accuracy. International Standards and best-practice guides

Selection and Treatment of Data for Radiocarbon Calibration: An Update to the International Calibration (IntCal) Criteria [PDF]

, 2013
High-quality data from appropriate archives are needed for the continuing improvement of radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating that necessitate calibration and the relative strengths and weaknesses of ...

Profiling and Pairing Catchments and Hydrological Models With Latent Factor Model

Water Resources Research, 2023
Hydrological models are simplified representations of catchments. Finding an appropriate model instance (i.e., a combination of structure and parameter values) for a given catchment is a fundamental problem in hydrological modeling. This study develops a

A Cross-Subject sEMG-to-Speech Conversion System Using Content Features and Model Calibration

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Current sEMG-based speech generation methods primarily rely on large-scale datasets from single participants, which imposes a burden on users. Moreover, previous research methods often require synchronous recordings of sEMG speech for model training ...

Assessing the Calibration of Dichotomous Outcome Models with the Calibration Belt [PDF]

The Stata Journal: Promoting communications on statistics and Stata, 2017
The calibration belt is a graphical approach designed to evaluate the goodness of fit of binary outcome models such as logistic regression models. The calibration belt examines the relationship between estimated probabilities and observed outcome rates. Significant deviations from the perfect calibration can be spotted on the graph.

A simple NWA calibration algorithm based on a transfer standard [PDF]

, 1997
A new two-port network analyzer (NWA) calibration technique is here presented. It uses a single two-port transfer standard plus a known reflectance to perform the calibration process.
