Adaptive solution of problems modeled by unified state variable constitutive equations
Computer Assisted Methods in Engineering and Science, 2023 The objective of the work was an efficient, numerical implementation of one of the unified, internalstate-variable constitutive models. Such models are general and convenient in numerical applications since they describe elastic, plastic, viscous ...

Iterative QR-Based SFSIC Detection and Decoder Algorithm for a Reed–Muller Space-Time Turbo System
Entropy, 2017 An iterative QR-based soft feedback segment interference cancellation (QRSFSIC) detection and decoder algorithm for a Reed–Muller (RM) space-time turbo system is proposed in this paper. It forms the sufficient statistic for the minimum-mean-square error (

Impact of nonlinearity on changing the a priori of trace gas profile estimates from the Tropospheric Emission Spectrometer (TES) [PDF]
Atmospheric Chemistry and Physics, 2008 Non-linear maximum a posteriori (MAP) estimates of atmospheric profiles from the Tropospheric Emission Spectrometer (TES) contains a priori information that may vary geographically, which is a confounding factor in the analysis and physical ...

Maximum a posteriori estimation for high-throughput peak fitting in X-ray photoelectron spectroscopy
Science and Technology of Advanced Materials: MethodsWe introduce a peak fitting method to estimate the model parameters and the number of peaks without using the conventional trial-and-error approach. The proposed method automatically removes excess peaks using maximum a posteriori estimation.

Complementarity based a posteriori error estimates and their properties
Mathematics and Computers in Simulation, 2012 The paper studies complementary approaches in a posteriori finite element error estimation for a diffusion-reaction model problem. These approaches provide sharp and guaranteed upper bonds for the energy norm of the error and they are independent from the way how the approximate solution is obtained. Numerical tests are also discussed.

A-posteriori error estimators and RFB
, 2016 We derive a posteriori bounds for the residual-free bubble (RFB) method for the solution of convection-dominated diffusion equations. Both linear functional error control and energy norm error control are considered. The implementation of a reliable and efficient $h$ adaptive algorithm is discussed.
