20040244316, Dec 9, 2004

Filed:

Jun 2, 2004

Appl. No.:

10/859277

Inventors:

James Macuga - Concord OH, US
Christopher Harris - Los Angeles CA, US

International Classification:

E04B007/00

US Classification:

052/198000

Abstract:

A roof covering () comprising a plastic film () and an adhesive () positioned under the lower film surface (). The film () can be a plastic film selected to provide substantial solar reflectance and high thermal emittance and the adhesive () can be a pressure-sensitive adhesive. The roof covering () of the present invention can be provided in a roll, sheets, or other medium, and it can be applied to an EPDM membrane after the membrane is assembled to the roof. The roof covering () can instead be incorporated into a laminate including an EPDM membrane and assembled to the roof at the same time as the membrane.

Assignee:

Atom Nanoelectronics, Inc. - Los Angeles CA

International Classification:

C01B 32/162
B82Y 30/00
B82Y 40/00

Abstract:

Single-walled nanotubes for use as additives in energetic materials, and methods for synthesizing such materials are described. The single-walled carbon nanotube (SWNT) additives comprise a mixture of high-purity SWNT and carbon encapsulated iron nanoparticles. The SWNT mixtures may comprise no more than 5% non-SWNT carbon, and the iron nanoparticles may be from 2-5 nm. The method of synthesizing the SWNTs may comprise a high-pressure carbon monoxide (HiPCO) process. The SWNT mixtures may be adapted for use as additives in energetic processes, such as, for example, rocket motors.

Abstract:

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for ranking content items. In one aspect, a method includes identifying, for a content item, a bid value specifying an amount a content item provider is willing to pay for user interaction with the content item. A predicted performance measure is identified for the content item. The predicted performance measure is adjusted based on a weighting factor for the content item. The weighting factor for the content item is indicative of confidence that the predicted performance measure will match an actual performance measure for the content item and can be different than a weighting factor for another content item identified for inclusion in a ranking with the content item. A rank score is determined for the content item using the bid value and adjusted predicted performance measure. The content item is provided based on the rank score.
