Smectic-A Order at the Surface of a Nematic Liquid Crystal: Synchrotron X-Ray Diffraction
(American Physical Society, 1982)
A novel geometry in which it is possible to do x-ray diffraction from a horizontal surface of fluids is applied to liquid crystals. A large-diameter drop of octyloxycyanobiphenyl (8OCB) on a glass plate treated for homeotropic ...
DIALOGIC: A Core Natural-Language Processing System
(Association for Computational Linguistics/ Academia Praha, Czechoslovakia, 1982)
The DIALOGIC system translates English sentences into representations of their literal meaning in the context of an utterance. These representations, or "logical forms," are intended to be a purely formal language that is ...
Synchrotron X-Ray Study of Novel Crystalline-B Phases in Heptyloxybenzylidene-Heptylaniline (7O.7)
(American Physical Society, 1982)
This paper reports an x-ray diffraction study of structures and restacking transitions within the B phases of heptyloxybenzylidene-heptylaniline. The system evolves from a hexagonal close-packed structure, through intermediate ...
Anomalous Temperature Dependence of the Elastic Constant B at the Smectic-to-Nematic Phase Transition in Binary Mixtures of Hexyloxycyanobiphenyl-Octyloxycyanobiphenyl (60CB-80CB)
(American Physical Society, 1982)
In hexyloxycyanobiphenyl-octyloxycyanobiphenyl (60CB-80CB) binary mixtures displaying reentrant behavior, the smectic elastic constant, B, deviates from a simple power law of the form \(B=B_1(T_{NA}-T)^{\varphi}\) and ...
A catalogue of [100], [110], and [111] symmetric tilt boundaries in face-centered cubic hard sphere crystals.
(Harvard Division of Applied Sciences, 1982)
An Atomistic Model of Solute Trapping
(National Bureau of Standards, 1982)
Translating English into logical form
(Association for Computational Linguistics, 1982)
A scheme for syntax-directed translation that mirrors compositional model-theoretic semantics is discussed. The scheme is the basis for an English translation system called PATR and was used to specify a semantically ...
