Light pulse atom interferometry can be used to realize high-performance sensors of accelerations and rotations. In order to broaden the range of applications of
This document provides an overview of a new ISO standard, ISO/CD 10303-231, for exchanging process engineering information among process design and process
Estimates of the World Trade Center (WTC) towers response to wind by two North American wind engineering laboratories differed from each other by almost 40 %. A
Long-term service life of a load-bearing ceramic component such as a turbine blade atelevated temperatures is often controlled by the rates of nucleation and

Database-assisted design (DAD) was originally developed for low-rise buildings. In this paper we show that it applies to flexible high-rise buildings as well
Low-speed friction experiments were conducted under boundary lubrication in a pin-on-disk tester. The 304 stainless steel disk had smooth areas alternating with
Brancusi s Endless Column (T rgu-Jiu, Romania) has been referred to as aeroelastically indifferent owing to its remarkable aeroelastic stability. The column s

Three types of liquids were found in the BSCCO system: transient, metastable, and stable liquids. The roles of these liquids are discussed with examples
We summarize results of ongoing research at the National Institute of Standards and Technology into the development of a new generation of standard provisions
The 48th Annual Denver X-ray Conference took place at Sheraton Steamboat Resort, Colorado, from August 2-6, 1999. This meeting was well attended, with a
We have uncovered the fact that colloidal probes often have random surface features which when not properly accounted for, can significantly affect the
