Manufacturing of AgMg sheathed Bi2Sr2CaCu2O8+x superconducting tapes involves multiple processes. Microstructural studies across tape sections have shown that the microstructure is nonuniform across the tape. These nonuniformities are largely due to manufacturing defects, even in well-controlled manufacturing processes. Consequently, the electrical and mechanical properties vary in these differ...

This article documents the circumstances surrounding composition of soundtrack to theatrical production Bridget Boland’s The Prisoner in 1954. Roberto Gerhard’s is likely first piece utilise ensemble and magnetic tape, as such potentially live performance musique concrète England, taking place a year before significantly more infamous electronic score King Lear , produced by Royal Shakespeare C...

The problems of provision of information for a new interdisciplinary topic are outlined. An experimental system using input in the form of magnetic tape subsets from existing secondary services is described, and ways of overcoming difficulties arising from lack of standardisation and coordination amongst these services are proposed.

The magnetic hard disc drive industry continues to face serious challenges in its quest for ever decreasing bit size. This review summarizes recent advances and promising new technology which have foundations in fundamental physical principles. Some advantages of these new ideas are illustrated through micromagnetic modeling and the numerous challenges associated with their implementation are h...

Magnetic recording currently is the major data storage technology. Conventional magnetic media implement continuous magnetic layers consisting of microscopic grains. Such media have constraints of thermal instability due to the superparamagnetic effect, which occurs when the magnetic grains become too small. The superparamagnetic effect may set the fundamental limit of about 0.5Tbit/inon achiev...

The behavior of the Sun and near-Earth space during grand solar minima is not understood; however, the recent long and low minimum of the decadal-scale solar cycle gives some important clues, with implications for understanding the solar dynamo and predicting space weather conditions. The speed of the near-Earth solar wind and the strength of the interplanetary magnetic field (IMF) embedded wit...

Theoretical predictions were made for the dynamic performance of a tangential flux magnetic thrust bearing. A prototype bearing was built with the stators and rotors made from tape wound strip. The performance of this bearing was measured and compared to the theoretical predictions and also to the performance of a radial flux thrust bearing. Tangential flux bearings are intrinsically amenable t...
