Inverse modelling of European N₂O emissions: assimilating observations from different networks [PDF]

, 2010
We describe the setup and first results of an inverse modelling system for atmospheric N2O, based on a four-dimensional variational (4DVAR) technique and the atmospheric transport zoom model TM5. We focus in this study on the European domain, utilizing a

Sine Half-Logistic Inverse Rayleigh Distribution: Properties, Estimation, and Applications in Biomedical Data

Journal of Mathematics, 2021
A new lifetime distribution with two parameters, known as the sine half-logistic inverse Rayleigh distribution, is proposed and studied as an extension of the half-logistic inverse Rayleigh model.

Estimating models of inverse systems

52nd IEEE Conference on Decision and Control, 2013
This paper considers the problem of how to estimate a model of the inverse of a system. The use of inverse systems can be found in many applications, such as feedforward control and power amplifier predistortion. The inverse model is here estimated with the purpose of using it in cascade with the system itself, as an inverter.

Eigenvalue based inverse model of beam for structural modification and diagnostics: examples of using

Latin American Journal of Solids and Structures
In the work, in order to solve the inverse problem, i.e. the problem of finding values of the additional quantities (mass, elasticity), the beam inverse model was proposed. Analysis of this model allows finding such a value of additional mass (elasticity)

An inverse seesaw model with A4-modular symmetry

Nuclear Physics B, 2021
We discuss an inverse seesaw model based on right-handed fermion specific U(1) gauge symmetry and A4-modular symmetry. These symmetries forbid unnecessary terms and restrict structures of Yukawa interactions which are relevant to inverse seesaw mechanism.

Solving inverse scattering problems via reduced-order model embedding procedures

, 2023
We present a reduced-order model (ROM) methodology for inverse scattering problems in which the ROMs are data-driven, i.e. they are constructed directly from data gathered by sensors.

Correlation, Independance and Inverse Modeling [PDF]

, 2008
Learning from examples has a wide number of forms depending on what is to be learned from which available information. One of these form is y = f( x ) where the input-output pair ( x , y ) is the available information and frepresents the process mapping ${\bf x}\in\cal X$ to ${\bf y}\in\cal Y$.

MATHEMATICAL MODELS FOR CHROMOSOMAL INVERSIONS [PDF]

Genetics, 1967
INCE a formal characterization of the nature of inversions has not been made to date, this paper will hypothesize mathematical models for the occurrence of inversions of various lengths, obtain the associated probability distributions of lengths and midpoints of chromosomal inversions, and compare the hypothesized models with two sets of data.

Applications of inverse simulation to a nonlinear model of an underwater vehicle [PDF]

, 2008
Inverse simulation provides an important alternative to conventional simulation and to more formal mathematical techniques of model inversion. The application of inverse simulation methods to a nonlinear dynamic model of an unmanned underwater ...
