A lumped parameter is equal or proportional to some average value of the corresponding distributed parameter. Like any average quantity it gives no information regarding the form of the distribution. The use of lumped parameters therefore requires some assumptions, expressed or implied, regarding the ...

Along with the standard components, several other components are introduced in this interface. One of them is the impedance, which is used to create a difference in both displacements and forces. Another one is the external source, which can be used to connect a distributed model to the lumpe...

The Lyapunov-function method is used to investigate the stability of systems with distributed parameters and lumped forces described by linear partial differential equations (for example, elastic structures with lumped masses, dampers, elastic aircraft with rigid control rudders, etc.). By introducing ...

network parametersFor long gate-width FET devices, distributed model provides better accuracy. However the extraction of model parameters are difficult as they are expressed in unit gate width which may be different from the device under investigation. In this paper a technique is proposed for ...
