The Laplacian Pyramid as a Compact Image Code

We describe a technique for image encoding in which local operators of many scales but identical shape serve as the basis functions. The representation differs from established ...

Structural and electrical properties of granular metal films

Granular metal films (50–200,000 Å thick) were prepared by co-sputtering metals (Ni, Pt, Au) and insulators (SiO2, Al2O3), where the volume fraction of metal, x, was varied from...

Heat capacity and thermal conductivity of hexagonal pyrolytic boron nitride

We have measured the heat capacity and thermal conductivity of the layered material hexagonal pyrolytic boron nitride from 2 to 10 K by a pulse-heating technique. The thermal co...

Majority Gate Networks

This paper presents methods for realizing simple threshold functions of n arguments by networks of k-input majority gates, where k≪n. An optimal network realization of the 5-arg...

Effect of Electron Pressure on Plasma Electron Oscillations

A general equation for electron motion in a plasma is developed which includes a term arising from electron gas pressure. The resulting expression is $\frac{{\ensuremath{\partia...
