Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

A minimum matrix valued risk estimator combining restricted and ordinary least squares estimators

Communications in Statistics - Theory and Methods, 2021
In this article, attention is focused on the convex combination estimator, β¯=Aβ+(I−A)βR. We have proved that the matrix valued risk of the new convex matrix estimator cannot exceed the individua...

Frequency and Phase-Angle Estimation Using Ordinary Least Squares

IEEE Transactions on Industrial Electronics, 2015
The extensive use of grid-connected power electronics converters in the most different conditions, e.g., grid voltage quality, power level and grid codes, requires a robust synchronization method in order to properly feed other converter controllers with reliable and exact information, namely the phase-angle and the magnitude of the grid voltage.
