Previously, experimental results have been presented showing that Mn-Zn ferrite core losses rise significantly with dc bias levels due to an increase in magnetostrictive vibration. In addition, it has been shown that the presence of a high level of remanent flux density, Br, left within a core after the removal of a dc bias can significantly increase core losses and, therefore, influenc...

This paper presents a magnetic centrifugal pump, driven by an external rotating magnetic field, for use in artificial heart-assist blood pumps. The magnet rotor in the pump is synchronized to a rotating magnetic field, which then causes the fabricated impeller to produce a centrifugal force in the pump. Because the pump is driven by the direct application of an external rotating magnetic field, th... View full abstract»

Shingled writing has recently emerged as a promising candidate to sustain the historical growth of magnetic recording storage areal density. However, since the convenient update-in-place feature is no longer available in shingled recording, in order to update one sector, many sectors must be read and written back, leading to a significant update-induced latency overhead.
