DS3906 Triple NV Low Step Size Variable Resistor Plus Memory General Description

... The DS3906 is intended for low resistance, small stepsize applications. It contains three nonvolatile (NV), lowtemperature coefficient, variable digital resistors that are capable of ohm and subohm increments when used in parallel with a fixed external resistor. All three of the DS3906’s resistors h ...

ABSTRACT NOVEL TRANSPORT PROPERTIES OF ELECTRON-DOPED SUPERCONDUCTORS Pr

... Electron-doped cuprate superconductors have demonstrated many distinct properties from their hole-doped counterparts. A few of them are investigated in this thesis. For example, by taking advantage of the low upper critical field, we investigated the field driven normal state thermoelectric power at ...

Lumped element model



The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
