In this paper, some preliminary results of mapping rice growth using TerraSAR-X HHVV dual polarization data are presented. Three TerraSAR-X images were collected in southern China during a rice growth cycle to analyze the temporal response of the rice fields at X-band. The height, the leaf area index (LAI) and the biomass of rice were also measured during acquisition of the SAR data, and empirical...
We propose an exact analysis for the scattering of an anti-plane shear wave by a piezoelectric circular cylinder in a piezomagnetic matrix with imperfect interfaces. Two typical imperfect interfaces are investigated: mechanically stiff and highly electromagnetic conducting interfaces, and mechanically compliant and weakly electromagnetic conducting interfaces. We obtain the fields of scattered wave...
It is well known that a negative feedback interconnection of passive systems is passive. However, the extension of this fundamental property to the case of negative feedback interconnection of dissipative systems, which is a more general case, remains largely unaddressed. In this paper, we demonstrate that a negative feedback interconnection of dissipative systems, under appropriate assumptions, could...
In this paper, we study the output synchronization problem of networked Euler-Lagrange(EL) systems subject to nonholonomic constraints. An EL system subject to nonholonomic constraints can be input-output linearized if a proper decoupling matrix can be found, and the linearized form is equivalent to a double integrator. Although a double integrator is not a passive system, with proper design of the...
