A DataMesh can be viewed equally well as a storage server with a lot of local processing power, or as a highly-parallel computer with embedded storage. A physical manifestation might be as a wall-sized array of storage/processor nodes (discs, optical drives, pageaddressable RAM, etc) linked together by a web-like interconnect. Such a thing would live in the basement, and serve the storage needs...

Resonant optical cavities have been demonstrated to improve energy efficiencies in Holographic Data Storage Systems (HDSS). The orthogonal reference beams supported as cavity eigenmodes can provide another multiplexing degree of freedom to push storage densities toward the limit of 3D optical data storage. While keeping the increased energy efficiency of a cavity enhanced reference arm, image b...

This paper presents performance analysis of an adaptive Volterra/Hybrid equalizer in a nonlinear magneto-optic data storage channel. In a data storage system, nonlinear intersymbol interference (ISI) is one of the limiting factors for high storage density. Volterra and Hybrid (combination of linear and Volterra) equalizers are proposed and developed for compensation of nonlinear ISI. The use of...

objectives: this study was undertaken to evaluate the viability of periodontal ligament (pdl) cells of avulsed teeth in three different storage media. materials and methods: forty-five premolars extracted for orthodontic therapeutic purposes were randomly and equally divided into three groups based on storage media used [group i: milk (control); group ii: aloe vera (experimental); group iii: eg...

Fulgide is well-known as a thermally irreversible organic photochromic compound [1,2]. It is one of the important materials in the field of optical signal processing and optical storage. Focusing on the holographic storage applications of 3indoly-benzylfulgimide/PMMA film, in this chapter include the following themes. In section 2, first the Fulgide, photochroism and photo-induced anisotropy ar...

Homogenous wear resistant carbon coatings with an optical gap of 3 eV but low stress are needed to increase the storage density in optical storage disks in order to reach 100 GB in 12-cm diameter disks. Here, hydrogenated amorphous carbon (aC:H) films are deposited at room temperature using a large area electron cyclotron wave resonance plasma beam source of 14.2inch diameter. Methane is used a...

The chaotic nature of a storage-ring Free Electron Laser (FEL) is investigated. The derivation of a low embedding dimension for the dynamics allows the low-dimensionality of this complex system to be observed, whereas its unpredictability is demonstrated, in some ranges of parameters, by a positive Lyapounov exponent. The route to chaos is then explored by tuning a single control parameter, and...

This chapter describes the progress in using optical technology to construct high-speed artificial higher order neural network systems. The chapter reviews how optical technology can speed up searches within large databases in order to identify relationships and dependencies between individual data records, such as financial or business time-series, as well as trends and relationships within th...
