Filed:

Apr 16, 1996

Appl. No.:

8/632958

Inventors:

Zhe Li - Berkeley CA
Kenneth A. Ross - New York NY

Assignee:

The Trustees of Columbia University in the City of New York - New York NY

International Classification:

G06F 1730
G06F 722

US Classification:

395602

Abstract:

A technique for efficiently joining multiple large tables in a database system with a processor using a small main memory. The technique utilizes a join index and minimizes the number of Input/Output operations while maximizing the use of the small main memory through a buffer allocation process. Three embodiments of the technique are described all of which use the parallel-merge operation. The first technique, slam-join, is for joining two tables and does not require any pre-allocation of buffers to perform the join operation. The second technique, multi-slam-join, is for joining three or more tables and adds the parallel-merge technique to a join technique which partitions memory to be used for an efficient join operation. The third technique, called parallel-join, processes each input table completely independently using the parallel-merge technique. The parallel-merge technique identifies the lowest value from multiple files and orders all the values from lowest to highest.

US Classification:

403267, 156305, 156 94, 295271

Abstract:

The described embodiments relate generally to methods to enhance cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by the friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line in with a cosmetic surface portion of friction stir processed parts. In some embodiments cold spray can be used to on its own to create a cosmetic joint between various parts. Structural joints between first and second substrates may also be formed via solid state deposition. Such joints may be strengthened through use of a hidden weld, mechanical interlocking between the substrates, and/or coupling via fasteners.
