A power conservative Thevenin-Norton and Norton-Thevenin transformations are proposed in this letter. The transformations introduce a voltage and a current generators for which parameters depend on the loading impedance value.
متن کاملE-Companion for “A Generalized Norton-Bass Model for Multigeneration Diffusion”
The expressions for y2(t) and Y2(t) shown in Equations (11) and (12) are valid only if G2 is the latest generation available. Now suppose a generation 3 (G3) is introduced at τ3 (τ3 ≥ τ2). Similar to the shifting from G1 to G2 after τ2, some of the existing and potential adopters of G2 will consider adopting G3 after τ3. In order to derive the number of leapfrogging and switching adoptions betw...
متن کاملLandauer Defended: Reply to Norton
Ladyman et al (2007) proposed a model of the implementation of logical operations by physical processes in order to clarify the exact statement of Landauer’s Principle, and then offered a new proof of the latter based on the construction of a thermodynamic cycle, arguing that if Landauer’s Principle were false it would be possible to harness a machine that violated it to produce a violation of ...

After e...
