Spectral-based printer modeling and characterization [PDF]

Journal of Electronic Imaging, 2005
Spectral characterization involves building a model that relates the device dependent representation to the reflectance func- tion of the printed color, usually represented with a high number of reflectance samples at different wavelengths. Look-up table-based approaches, conventionally employed for colorimetric device char- acterization cannot be ...

Комплекс программ моделирования геодинамо на основе спектральных эредитарных моделей

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Исследование задачи геодинамо часто проводят на основе спектральных моделей, когда поля задачи полностью или частично раскладываются по собственным полям (модам) подходящих спектральных задач.

A spectral model for multimodal redshift estimation [PDF]

2016 IEEE Symposium Series on Computational Intelligence (SSCI), 2016
We present a physically inspired model for the problem of redshift estimation. Typically, redshift estimation has been treated as a regression problem that takes as input magnitudes and maps them to a single target redshift. In this work we acknowledge the fact that observed magnitudes may actually admit multiple plausible redshifts, i.e.

Running of the spectral index and inflationary dynamics of F(R) gravity

Physics Letters B, 2022
In this work we shall provide a model-independent general calculation of the running of the spectral index for vacuum F(R) gravities. We shall exploit the functional form of the spectral index and of the tensor-to-scalar ratio in order to present a ...

Spectral goodness of fit for network models [PDF]

Social Networks, 2014
We introduce a new statistic, 'spectral goodness of fit' (SGOF) to measure how well a network model explains the structure of an observed network. SGOF provides an absolute measure of fit, analogous to the standard R-squared in linear regression.

Generalized spectral tests for the martingale difference hypothesis [PDF]

, 2006
This article proposes a test for the martingale difference hypothesis (MDH) using dependence measures related to the characteristic function. The MDH typically has been tested using the sample autocorrelations or in the spectral domain using the ...

Многомасштабная модель геодинамо: сопряжение крупномасштабной и мелкомасштабной подмоделей

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Формирование главного геомагнитного поля обеспечивается работой механизма гидромагнитного динамо — генерации магнитного поля движением проводящей среды. Динамо Земли (геодинамо) управляется конвекцией жидкого металла во внешнем ядре Земли.

Sensitivity experiments to mountain representations in spectral models

Annals of Geophysics, 2000
This paper describes a set of sensitivity experiments to several formulations of orography. Three sets are considered: a "Standard" orography consisting of an envelope orography produced originally for the ECMWF model, a"Navy" orography directly from the

Spectral Characteristics of Biological Soil Crusts under the Different Types in the Water-Wind Erosion Crisscross Region on the Loess Plateau

, 2018
The study on spectral characteristics of biological soil crust in the water-wind erosion crisscross region in the Loess Plateau has important scientific value for the identification of biological soil crust based on remote sensing technology at regional ...

A predictive model for the spectral “bioalbedo” of snow [PDF]

Journal of Geophysical Research: Earth Surface, 2017
AbstractWe present the first physical model for the spectral “bioalbedo” of snow, which predicts the spectral reflectance of snowpacks contaminated with variable concentrations of red snow algae with varying diameters and pigment concentrations and then estimates the effect of the algae on snowmelt.
