US Patent:

47602546, Jul 26, 1988

Filed:

Jun 7, 1985

Appl. No.:

6/742233

Inventors:

Daniel T. Pierce - Gaithersburg MD
Robert J. Celotta - Gaithersburg MD
John Unguris - Damascus MD

International Classification:

G01N 2700
H01J 4000
H01J 4700

US Classification:

250305

Abstract:

Provided herein are a device and a method for determining the spin polarization of an electron beam where the device and method contemplate diffusely backscattering the beam from an electron opaque target, at a kinetic energy less than 10,000 electron volts, collecting the scattered electrons which may be of a preselected energy range and within a predetermined solid angle relative to the target and the collector, and measuring the number of scattered electrons which were collected.

Abstract:

According to embodiments of the present invention, methods, systems and computer readable media are provided, in a cognitive data processing system, for implementing a predictive analytics system that utilizes entity and non-entity information. A collection of content is processed to extract defined entities pertaining to one or more domains. Semantic relationships are determined between objects within the collection of content, wherein the objects include undefined entities. The defined entities and objects are resolved based on entity definitions and the semantic relationships to determine defined entities and undefined entities for a resulting data set. The resulting data set is processed to identify one or more relationships between a defined entity and an undefined entity.
