The requirements for a main memory data storage model are both compactness and efficient processing for all database operations. The DBGraph storage model, proposed in this paper, achieves these goals. By representing the entire database in a unique graph-based data structure, called DBGraph, it fully exploits the directaccess capability of main memory systems. For example, Selection, Join and ...

We describe and demonstrate a volume holographic storage system in which a phase-conjugate object beam is reconstructed by the same reference beam that was used for recording. An intermediate hologram is used as a temporary buffer, recorded with its own reference beam and the data-bearing object beam. Reading this buffer hologram with the phase conjugate of its reference beam reconstructs the p...

At cross docking terminals, products from incoming trucks are sorted according to their destinations and transferred to outgoing trucks using a small temporary storage. Such terminals allow companies to reduce storage and transportation costs in a supply chain. This paper focuses on the operational activities at cross docking terminals. We consider the trucks scheduling problem with the objecti...

I . The effects of ingestion of diets deficient in both copper and iron on storage of these elements and on the red cell indices have been studied in rats. 2. Injection of Cu into rats whose stores of Cu had been virtually exhausted resulted in a temporary increase in the concentration of plasma Fe and depletion of the Fe stored in the liver. Storage of Fe in the spleen seemed to be affected so...

Investigates the relationship between three factors of working memory (storage and processing, relational integration, and supervision) and four factors of intelligence (reasoning, speed, memory, and creativity) using structural equation models. Relational integration predicted reasoning ability at least as well as the storage-and-processing construct. Supervision, measured as specific switch c...
