Improvement in second harmonics linearization technique for multichannel amplifiers

open access: yes, 2003
A linearization technique that uses the injection of the fundamental signal second harmonics together with the fundamental signals at the amplifier input has been improved in this paper by introducing phase correction of the fundamental signals according

On harmonic and asymptotically harmonic Finsler manifolds

open access: yesAnnals of the Alexandru Ioan Cuza University - Mathematics
In the present paper we introduce and investigate some types of harmonic Finsler manifolds and find out the interrelation between them. We give some characterizations of such spaces in terms of the Finsler mean curvature of geodesic spheres and the Finsler Laplacian of the distance function induced by the Finsler metric.
