摘要:
A base table and related auxiliary table spaces are reorganized concurrently via a database utility. The database utility determines which auxiliary tables are related to the base table and automatically includes their respective auxiliary table in the same invocation of the utility. The reorganization is performed via allocated shadow data sets. The original data sets are switched with the newly built shadow data sets including the LOB shadows.

摘要:
Metal flakes, an organic metal precursor, an organic solvent and either no binder, or a volatile or a thermally decomposable binder are combined to form a paste. The paste is deposited in a circuit pattern on a substrate and the circuit pattern is cured. While curing, the organic metal precursor decomposes to leave an electrically conductive path, and the printed circuit is thus formed. A precursor to an electrically conductive circuit material includes an organic metal precursor, metal microparticles, and an organic solvent. The method can be employed to form printed circuits, for a variety of electrical, electronic and sensing application, such as crack detection in ceramic, plastics, concrete, wood, fabric, leather, rubber or paper and composite materials.

Wireless strain and displacement sensors wirelessly monitor structural health and integrity, and are made by printing inductor-interdigital capacitor sensing circuits on a variety of substrates, including ceramic substrates, with thermally processable conductive inks. Sensors of the invention can be employed to detect strain and displacement of civil structures, such as bridges and buildings. The sensors include sensing elements that are mounted or printed on stiff, inflexible substrates, which prevent the sensing elements from bending, stretching, or otherwise warping when the sensor is strained. An interlayer between the sensing elements allows the sensing elements to move with respect to each other during application of strain. Thus, strain causes the sensing elements to move but not to deform, causing changes in sensor resonance that can be detected through wireless radio-frequency interrogation. Because the sensing elements do not change shape when under strain, the sensor can undergo millions of measurement cycles before breaking.

The present invention relates to methods of fabricating nanostructures using a replacement reaction. In a preferred embodiment, metal particles in an inert atmosphere undergo a replacement reaction to form a layer on the metal particle which is removed to form a high surface area nanostructure. A preferred embodiment includes the fabrication of heater elements, powders and heater assemblies using the nanostructures.

A method and article of manufacture, implementing the method, allocates space for a dataset. The dataset has an initial area and zero or more additional allocated areas to provide space for storing the dataset. The size of a new additional area is determined. The new additional area is associated with a new area number, and the size of the new additional area is based on the new area number. Additional space for the dataset is allocated based on the size of the new additional area. Alternately, an apparatus stores a dataset. A computer has a data storage device connected thereto. The data storage device has a plurality of areas for storing a dataset. The plurality of areas comprises an initial area having an initial area size and a plurality of additional areas having an additional area size, wherein the additional area size varies. In one embodiment, the additional area size monotonically increases.
