In a human hip joint, the motion is complex and consists of flexion/extension, abduction, and adduction. Laboratory studies have shown that these motions...
This paper is an interim report on our efforts at NIST to construct an information discovery tool through the fusion of Hypertext and Information Retrieval (IR)...
Brute force exploration of the simple cubic effective cluster interaction space indicates that linear triplet interaction is both necessary and sufficient to...
This paper examines a wide class of ill-posed initial value problems for partial differential equations, and surveys logarithmic convexity results leading to...
The general theories of the derivation of inverses of functions from their power series and asymptotic expansions are discussed and compared. The asymptotic...
This article extends the results of [3] by establishing sufficient conditions for the limit distribution of products of i.i.d. 2 x 2 random stochastic matrices...
Impressive advances are being made in the field of display metrology, as illustrated in standards such as the Video Electronics Standards Association's Flat...

(Ba,Sr) yTiO 2+y thin films with 0.34 {1-xSr xTiO 3 (x {aproximately equal to} 0.06) and an amorphous phase. The orientation of the tetragonal Ba 1-xSr xTiO 3...
The electronic structure and spectroscopy of the oxovanadium catalytic center on a silica surface is modeled with the molecule OV(OSIH 3)3. Excited electronic...
This paper proposes that development of formalized standards for the rapid prototyping (RP) industry will help enable the continued growth and further...
Minimizing the uncertainty in the calibration of accelerometers by the reciprocity method requires minimizing the cross-axis component of the induced motion...
A major goal of the Building and Fire Research Laboratory is to provide the polymer industry with the technical understanding and measurement tools that are...

The behaviour of four cryogenic-fluid-dissolved-nitrogen mixtures inside a pressure vessel during rapid depressurization was investigated through experiment...
Recently, statistical process control (SPC) methodolgies have been developed to accommodate autocorrelated data. A primary method to deal with autocorrelated...
A large class of ocean-atmosphere models exists in which the ocean state is coupled to the model of the atmosphere only through the anomalies of the ocean state...
