Identification, Modeling, and Filtering of the Quantization Error in Encoder Equivalent Output
Encoder equivalent output is widely used in modern industrial drives equipped with tools for improving the encoder resolution. A standard application for this output is electronic gearing for controlling slave amplifiers via the encoder equivalent output of a master drive. If left uncorrected, this noise would report unreal noise to the user, or le...

Composition, Structure, and Method for Fabrication of Tunable Inductors with Large Tunability
Tunability of conventional inductors is achieved either by mechanically tuning through bias magnet(s) or by adjusting the electric current in solenoids/electromagnets. These devices are typically bulky, slow, noisy, and inefficient. Various efforts have been devoted towards developing voltage tunable inductors that have large tunability and low ene...

Highly Tunable Stationary Phases for Micro Gas Chromatography Using Room Temperature Ionic Liquids
We deposited a number room temperature ionic liquids inside the channels of semi-packed columns and used these columns for gas chromatographic separation of mixtures containing a number of polar and non-polar compounds. We demonstrated that these columns can be used for rapid and highly efficient separation of the components of different mixtures. ...
