The Alu family of intersperesed repeats is comprised of ovr 500,000 members which may be divided into discrete subfamilies based upon mutations held in common between members. Distinct subfamilies of Alu sequences have amplified within the human genome in recent evolutionary history. Several individual Alu family members have amplified so recently in human(More)

— This paper introduces (1) a family of multi-resonant passive components with harmonically related impedance nulls and maxima, (2) board-and wafer-scale construction techniques for such structures, and (3) circuit topologies that exploit the harmonically related impedance extrema they provide. A three-dimensional copper electroforming process has been(More)

—Transmission lines and their lumped approximating networks have long been incorporated into radio-frequency power amplifiers to improve efficiency and shape circuit waveforms and are beginning to perform a similar roles in high-frequency switched-mode power electronics. Though lumped line-simulating networks are often preferred to their distributed(More)
— A soft-switching inverter topology (the Class Φ) is presented which draws dc source current through a transmission line or a lumped-network approximation of a distributed line. By aligning the inverter switching frequency just below the line's λ/4-wave resonance, the Class Φ topology enforces odd-and even-harmonic content in its drain voltage and input(More)

This thesis presents a set of techniques for predicting point-of-load voltage distortion on the electric utility and in the electrical system of the automobile. Continuous-time models for the impedances of both the electric utility and the automobile chassis are constructed, and parameter estimates for continuous-time and discrete-time versions of these(More)
