Repeat Codes, Even Codes, Odd Codes and Their Equivalence
Codes over the chain ring are obtained by writing special matrices. Gray images of these codes are binary codes. It is shown that first repeat code, second repeat code, even code and odd code are either equivalent or equal to these codes. The definitions of direct sum and direct product of these codes ...
Error Estimates and Analysis Results for Signorini’s Problem in Thermo-Electro-Viscoelasticity
We consider a mathematical model describing the quasi-static process of contact between a thermo-electroviscoelastic body and a rigid foundation. The contact is described by Signorini’s conditions. The variational formulation leads to a coupled system for the displacement filed, the electric potential ...
