The probability of whisker growth on as-deposited tin (Sn) electrodeposits has been measured as a function of copper (Cu superscript2+) addition to a commercial
Polydomain micro- and nano-structures are natural products of phase transformations in solids. The trend to minimize the energy of internal long-range fields
Buried gas and oil pipelines can be subjected to unexpected bending loads causedby such earth movements as earthquakes, wash-outs, road building, mining
Ni-Mo and Fe-Mo alloys were electrodeposited using both DC and pulsed current from a phyrophosphate bath. Their composition and morphology were investigated by
We investigated the dielectric relaxation process in high-dielectric constant polymer composite films filled with barium titanate particles. In order to extend
Effective intrusion detection capability is an elusive goal, not solved easily or with a single mechanism. However, mobile software agents go a long way toward
Polarization-mode dispersion (PMD) is an interesting phenomenon. Unfortunately, interesting usually means complicated, and that is definitely the case with PMD
The American Society of heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has been revising Standard 62,Ventilation for Acceptable Indoor Air
This paper will discuss some of the challenges encountered during a recent key comparison. From these experiences, general lessons will be drawn that should

A portable Josephson voltage standard (JVS) system has been used as a transfer standard to make an interlaboratory JVS comparison. The results are compared with
Active-network technology envisions deployment of virtual execution environments within network elements, such as switches and routers. As a result, application
An international comparison of dc resistance at 10 Mohm and 1 GHohm was organized under the auspices of the Consultative Committee for Electricity and Magnetism
Indoor air quality is currently addressed in the design process primarily through prescriptive building codes based on specified flow rates. However, a
