Through expounding the superiorities of XML in the construction of the digital library,this paper points out that XML is the optimum selection of digital library s storage content in the future.

Preliminary estimation of CO_2 storage capacity in gas fields in China;

Measuring equivalent grating constant and storage capacity of CD;

It not only possesses merits of the BAM, but also relaxes the continuity assumption for reliable recalls and significantly improves the storage capacity and error correcting capability of the BAM.

Important limiting factors for volume holographic storage capacity such as optical limit,angular selectivity and dynamic range of storage medium are discussed respectively.

The memory capacity of Hopfield Neural Networks is analyzed and the typical data of the memory capacity is given on condition that the error probability Pc of a single neuron s output is constant.

This paper investigates privacy amplification, in which there exists a binary disrete memoryless broad- cast source which transmitting data at very high a rate, and an adversary s memory capacity is limited, no as- sumption about his computing power is made.
