Abstract:

A method, computer program, and computer system is provided for video encoding and decoding. Video data including a current picture is received. A virtual reference frame is generated for the current picture based on hierarchical level associated with the current picture and a nearest decoded picture. The video data is decoded based on the generated reference frame.

C22C 19/05
C22F 1/00
C22C 30/00

Abstract:

The present disclosure relates to new nickel-iron-aluminum-chromium based alloys. Generally, the new alloys contain 20-40 at. % Ni, 15-40 at. % Fe, 5-20 at % Al, and 5-26 at. % Cr, the balance being optional incidental elements and unavoidable impurities. Generally, methods for producing the new alloys include one or more of heating a mixture above its liquidus temperature, then cooling the mixture below its solidus temperature, optionally hot and/or cold working the solid material into a final product form, then heating and quenching the solid material, and precipitation hardening the solid material.

Abstract:

New aluminum alloys having iron, vanadium, silicon and copper are disclosed. The new alloys may include from 3 to 12 wt. % Fe, from 0.1 to 3 wt. % V, from 0.1 to 3 wt. % Si, and from 1.0 to 6 wt. % Cu, the balance being aluminum and impurities. The new aluminum alloys may be produced via additive manufacturing techniques, which may facilitate rapid solidification of a molten pool of the aluminum alloy.
