Modified boundary element method for the solution of connected problems of mathematical physics

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
The modified boundary element method for physico-mathematical modeling of the multifactorial processes is offered for discussion. Physical modeling based on the Onsager's theorem about the relationship between generalized forces and fluxes where we ...

Filtered Influence Function of Deformable Mirror for Wavefront Correction in Laser Systems

open access: yesPhotonics, 2021
An influence function filtering method (IFFM) is presented to improve the wavefront correction capability in laser systems by curbing the correction performance degradation resulted from the IF measurement noise.

Two symmetric and computationally efficient Gini correlations

open access: yesDependence Modeling, 2020
Standard Gini correlation plays an important role in measuring the dependence between random variables with heavy-tailed distributions. It is based on the covariance between one variable and the rank of the other. Hence for each pair of random variables,

Influence functionals and the accelerating detector [PDF]

open access: yesPhysical Review D, 1993
The influence functional is derived for a massive scalar field in the ground state, coupled to a uniformly accelerating DeWitt monopole detector in $D+1$ dimensional Minkowski space. This confirms the local nature of the Unruh effect, and provides an exact solution to the problem of the accelerating detector without invoking a non-standard quantization.

Restricted Distance-Type Gaussian Estimators Based on Density Power Divergence and Their Applications in Hypothesis Testing

open access: yesMathematics, 2023
In this paper, we introduce the restricted minimum density power divergence Gaussian estimator (MDPDGE) and study its main asymptotic properties. In addition, we examine it robustness through its influence function analysis.

Robust Inference after Random Projections via Hellinger Distance for Location-Scale Family

open access: yesEntropy, 2019
Big data and streaming data are encountered in a variety of contemporary applications in business and industry. In such cases, it is common to use random projections to reduce the dimension of the data yielding compressed data. These data however possess

INFLUENCE OF OLANZAPINE ON MEMORY FUNCTIONS

open access: yesPsychiatria Danubina, 2009
Even though memory dysfunction is not considered to be a diagnostic criterion for schizophrenia, results of a neuropsychological research indicate significant damage in mnestic functioning, especially in verbal memory (Saykin et al. 1991). This type of a disorder is recorded in patients with a first episode of schizophrenia, as well as in chronic ...

Robust Bootstrap

open access: yesRevstat Statistical Journal, 2014
There is a vast literature on robust estimators, but in some situations it is still not easy to make inferences, such as confidence regions and hypothesis testing. This is mainly due to the following facts.

Robust variance estimation and inference for causal effect estimation

open access: yesJournal of Causal Inference, 2023
We present two novel approaches to variance estimation of semi-parametric efficient point estimators of the treatment-specific mean: (i) a robust approach that directly targets the variance of the influence function (IF) as a counterfactual mean outcome ...

Assessment of South Pars Gas Field Subsidence Due To Gas Withdrawal [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2014
Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction.
