Multivariable Repetitive-predictive Controllers using Frequency Decomposition [PDF]

open access: yes, 2012
Repetitive control is a methodology for the tracking of a periodic reference signal. This paper develops a new approach to repetitive control systems design using receding horizon control with frequency decomposition of the reference signal.

Stability and strengthening effect of aging induced-nanofeatures in δ-ferrite in an austenitic stainless-steel weld

open access: yesJournal of Materials Research and Technology, 2023
The deformation behavior of δ-ferrite in an aged austenitic stainless-steel weld was investigated to obtain insights on the contribution of aging-induced nanofeatures, such as spinodal decomposition and G-phase precipitation, to aging embrittlement.

Performance degradation and recovery of YSZ membrane under sulphuric acid thermal decomposition [PDF]

open access: yes, 2013
The effect of sulphur dioxide (SO2) present in the cathode feed stream on the performance of a 8 mole% yttria-stabilized zirconia/platinum (8YSZ/Pt) cell was studied. SO2 concentration of 30% in oxygen (5ml/min) and helium (30ml/min) was exposed to

Introducing a new heterogeneous nanocomposite thin film with superior mechanical properties and thermal stability

open access: yesMaterials & Design, 2023
High entropy alloy (HEA) films offer excellent mechanical properties due to their random solid solution structure. However, their large grain boundary volume fraction can cause thermal instability, resulting in phase decomposition that affects their high-

3D simulation of laminated shell structures using the Proper Generalized Decomposition [PDF]

open access: yes, 2014
Numerical simulations of composite structures are generally performed using multi-layered shell elements in the context of the finite elements method. This strategy has numerous advantages like a low computation time and the capability to reproduce the ...

Time complexity analysis of generalized decomposition algorithm [PDF]

open access: yes, 1997
The time complexity of the fast algorithm for generalized disjunctive decomposition of an rvalued function is studied.The considered algorithm to find the best decomposition is based on the analysis of multiple-terminal multiple-valued decision diagrams.

A study of phase separation processes in presence of dislocations in binary systems subjected to irradiation

open access: yesCondensed Matter Physics, 2015
Dislocation-assisted phase separation processes in binary systems subjected to irradiation effect are studied analytically and numerically. Irradiation is described by athermal atomic mixing in the form of ballistic flux with spatially correlated ...
