The inverse conductivity problem in electrical impedance tomography involves the solving of a nonlinear and under-determined system equations. This paper presents new approach, which leads to quadratic overdetermined aim is establish research directions handling problem. basis proposed method that material, can be considered as an isotropic continuum, modeled linear network with concentrated pa...

This paper presents the results of the parameter estimation procedure for the primary circuit dynamics of a VVER-type nuclear power plant. The model structure is a low dimensional lumped nonlinear model published previously in Fazekas et al. [2007a]. The parameter estimation method uses the modular decomposition of the system model for obtaining physically meaningful initial parameter estimates...

In this paper, a novel type of dual-band bandpass filter (DBBPF) is proposed by using microstrip composite resonators, and its design method is developed based on the lumped-element equivalent circuit of the filter. Both the midband frequencies and the passband widths of the dual bands of the filter can be controlled separately. Four DBBPFs with different specifications are designed, fabricated...

The analytical modeling and simulation of conservative electrostatic, electromagnetic and electrodynamic transducers found in microsystems using a non-linear lumped-parameter approach is presented in this paper. A comparison is made between this approach and the linearized equivalent circuit method. All models of transducers are written in HDL-A, a proprietary analogue hardware description lang...

In the paper design of control processes for class of distributed parameter systems is presented. Controlled system is interpreted as lumped-input/distributed-output systems with dynamics modelled by finite element method. Schemes of distributed parameter control loops are arranged in software environment Distributed Parameter Systems Blockset for MATLAB & Simulink, which is third-party MathWor...
