Video servers store digitized, compressed continuous media information on high-capacity secondary or tertiary storage [6]. The secondary storage devices allow random accessible and provide short seek times compared to tertiary storage. Video server design differs significantly from that of traditional data storage servers due to the large size of the objects stored and the real-time requirement...

The equations for spin evolution of a particle in a storage ring are obtained considering contributions from the tensor electric and magnetic polarizabilities of the particle along with the contributions from spin rotation and birefringence effect in polarized matter of an internal target. Study of the spin rotation and birefringence effects for a particle in a high energy storage ring provides...

Design of novel multisegmented magnetic nanowires can pave the way for the next generation of data storage media and logical devices, magnonic crystals, or in magneto-plasmonics, among other energy conversion, recovery, and storage technological applications. In this work, we present a detailed study on the synthesis, morphology, structural, and magnetic properties of Ni, Co, and Ni-Co alloy an...

Our goal with this paper is to contribute a common theoretical framework for studying the performance of disk-storage devices. Understanding the performance behavior of these devices will allow the prediction of the I/O cost in modern applications. Current disk technologies di er in terms of the fundamental modeling characteristics which include the magnetic/optical nature, the angular and line...

Long-lived and high-fidelity memory for a photonic polarization qubit (PPQ) is crucial for constructing quantum networks. We present a millisecond storage system based on electromagnetically induced transparency, in which a moderate magnetic field is applied on a cold-atom cloud to lift Zeeman degeneracy and, thus, the PPQ states are stored as two magnetic-field-insensitive spin waves. Especial...

A new superferric magnetic storage ring with highly homogeneous eld at 1.45 T and weak electrostatic focussing is described which has been set up at the Brookhaven National Laboratory (BNL), USA, for a precision measurement of the magnetic anomaly of the muon. The toroidal storage volume has a radius of 7 m and a diameter of 9 cm. Precision magnetic eld determination based on pulsed NMR on prot...

In this study, we reported a facile synthesis of bimetallic FeCo nanoparticles (Fe-Co NPs) by FeSO4.7H2O and Co(Ac)2.4H2O in the presence of sodium borohydride and 2-thiotic acid. The structure and morphology of the nanoparticles were characterized by X-Ray Diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), and Transmission Electron Micros...
