External Bootstrap Tests for Parameter stability [PDF]
, 2002 This article considers tests for parameter stability over time in general econometric models, possibly nonlinear-in-variables. Existing test statistics are commonly not asymptotically pivotal under nonstandard conditions.

Treating the Solid Pendulum Motion by the Large Parameter Procedure
International Journal of Aerospace Engineering, 2020 In this paper, we consider the dynamical description of a pendulum model consists of a heavy solid connection to a nonelastic string which suspended on an elliptic path in a vertical plane.

Non Data Aided Parameter Estimation for Multi-User ARGOS Receivers [PDF]
, 2012 In this paper, parameter estimators are analyzed in the context of Successive Interference Cancelation (SIC) receivers for the ARGOS system. A Non Data Aided (NDA) feed forward estimator is proposed for the amplitude and the carrier phase parameters ...

Parameter sensitivity for large deformation inelastic problems
Computer Assisted Methods in Engineering and Science, 2023 The algorithm for parametric sensitivity assessment for both materially and geometrically nonlinear static problems is presented. Similarly to its geometrically linear version presented elsewhere, the sensitivity analysis is shown to reduce to a linear ...

Comparing parameter choice methods for regularization of ill-posed problems [PDF]
, 2011 In the literature on regularization, many different parameter choice methods have been proposed in both deterministic and stochastic settings. However, based on the available information, it is not always easy to know how well a particular method will ...

Exponential random graph model parameter estimation for very large directed networks.
PLoS ONE, 2020 Exponential random graph models (ERGMs) are widely used for modeling social networks observed at one point in time. However the computational difficulty of ERGM parameter estimation has limited the practical application of this class of models to ...

On the zeros of Jonquière's function with a large complex parameter. [PDF]
Michigan Mathematical Journal, 1984 Let \(C^*\) denote the complex z-plane cut from 1 to \(\infty\) along the positive real axis, and let \(\kappa =\kappa_ 0+i\kappa_ 1\) be a complex number. Let \(f_{\kappa}\) denote the analytic function on \(C^*\) whose representation in \(| z|

Structural Parameter Optimization for Large Spacing Sublevel Caving in Chengchao Iron Mine
Metals, 2021 Non-pillar sublevel caving is beginning to use large structural parameters in China. Appropriate structural parameters can effectively control the loss and dilution of stope and improve ore drawing efficiency. In this study, taking Chengchao Iron Mine as
