Advances in computing power. Computer processing speeds have increased a thousand-fold since the first microprocessor was introduced. The size of dynamic memory, which is used for active storage of the program code that is being executed, has reached capacities that exceed what used to be the standard for physical storage of data on a disk. These advances in processing speed and capacity have b...

TiO2-WO3 hybrid photocatalysts were prepared using wet-chemical technique, and their energy storage performance was characterized by electrochemical galvanostatic method. TiO2 powder was coupled with WO3 powder, which was used as electron pool and the reductive energy could be stored in. As a result, the prepared TiO2-WO3 had good energy storage ability while pure TiO2 showed no capacity and pu...

The newly found B40 is the first experimentally observed all-boron fullerene and has potential applications in hydrogen storage. Here we investigate the binding ability and hydrogen storage capacity of Ti-decorated B40 fullerene based on DFT calculations. Our results indicate that Ti shows excellent binding capability to B40 compared with other transition metals. The B40 fullerene coated by 6 T...

When mixed states are composed of s memory patterns, s types of mixed states, which can become equilibrium states of the model, can be generated. We found that the storage capacity for all mixed states diverged as 1/|f log f | when the s memory patterns were given correlation. We also investigated how the storage capacity of them change on the correlation coefficient between s memory patterns. ...

The storage capacity of the Hopfield model is about 15% of the network size. It can be increased significantly in the Potts-glass model of the associative memory only. In this model neurons can be in more than two different states. We show that even greater storage capacity can be achieved in the parametrical neural network (PNN) that is based on the parametrical four-wave mixing process that i...

We study the storage capacity of a fully-connected committee machine with a large number K of hidden nodes. The storage capacity is obtained by analyzing the geometrical structure of the weight space related to the internal representation . By examining the asymptotic behavior of order parameters in the limit of large K, the storage capacity Q c is found to be proportional to ]{ Jln ]{ up to th...

We study the storage capacity of a fully-connected committee machine with a large number K of hidden nodes. The storage capacity is obtained by analyzing the geometrical structure of the weight space related to the internal representation. By examining the asymptotic behavior of order parameters in the limit of large K, the storage capacity c is found to be proportional to K p ln K up to the le...

Nowadays, the utilization of storage capacity becomes an important issue in cloud storage. In this paper, we introduce two categories of data deduplication strategy, and extend the fault-tolerant digital signature scheme proposed by Zhang on examining redundancy of blocks to achieve the data deduplication. The proposed scheme in this paper not only reduces the cloud storage capacity, but also i...
