The ray-tracing (RT) algorithm has been used for accurately predicting the site-specific radio propagation characteristics, in spite of its computational intensity.

Low-density parity-check (LDPC) codes are favorable in low bit-error-rate and high code-rate applications.

A century ago Wiedemann 1 observed that if a suitable magnetic rod which carries a current is magnetized by an external axial field, a twist 1319 1320 T H E B E L L SYSTEM T E C H N I C A L J O U R

Si 2p photoemission is perhaps the most widely used technique for studying the structure of the Si/SiO sub 2 interface.

(PREVIOUS TITLE: A System and Methodology for Generating Random Modal Formulae) Previous methods for generating random modal formulae result either in flawed test sets of formulae that are too har

During the past few .years, a need has arisen for data smoothing techniques which can be applied, in real time, to radar observations of bodies traveling along highly predictable trajectories.

Modern microwave systems offer new approaches such as advanced packet compression and higher order modulation for increasing microwave channel capacity.

The ability to compositionally grade epitaxial semiconductor layers in a desired fashion is important for the fabrication of modern semiconductor devices and structures for device physics studies.

We have used a combination of electron-beam lithography, reactive ion etching (RIE) and ion implantation to produce structures of oriented single-crystal cobalt disilicide buried beneath the surfac
