We study the equilibrium domain structure and magnetic flux around a ferromagnetic (FM) film with perpendicular magnetization M 0 on a super-conducting (SC) substrate. At 4πM 0 < H c1 the SC is in the Meissner state and the equilibrium domain width in the film, l, scales as (l/4πλ L) = (l N /4πλ L) 2/3 with the domain width on a normal (non-superconducting) substrate, l N /4πλ L ≫ 1. Here λ L i...

We present a hybrid atom chip which combines a permanent magnetic film with a micromachined current-carrying structure used to realize a Bose-Einstein condensate. A novel TbGdFeCo material with large perpendicular magnetization has been tailored to allow small scale, stable magnetic potentials for ultracold atoms. We are able to produce 87 Rb Bose-Einstein condensates in a magnetic trap based o...

In this paper, we investigate the performance of perpendicular recording channel for dc-full and dcattenuation partial response targets under the environment of electronics noise and jitter noise. We compare the performance of partial-response maximum-likelihood (PRML) and noise-predictive maximum–likelihood (NPML) detector for both types of targets. The NPML system is more suited for dc-attenu...

Recently, more research has been conducted on moving object databases (MOD). Typically, there are three kinds of data for dynamic attributes in MOD, i.e., historical, current and future. Although many index structures have been developed for the former two types of data, there is not much work to deal with the future data. In particular, the problem of index update has not been addressed with e...

We report an approach to reduce grain size for perpendicular media by using an Ar-ion etched Ru seedlayer. The surface etching affects the microstructure of the subsequent high pressure deposited Ru2+SiO2 interlayer and magnetic layer, whose grain size can be controlled. SiO2 in the interlayer plays a more important role in grain size reduction on the etched seedlayer than the as-grown seedlaye...

The effect of carbonation on a one-year atmospherically exposed lime-treated soil structure is investigated. investigation involves analyzing the chemical characteristics and pore-structure modifications several specimens sampled up to 12 cm depth perpendicular surface. On comparing analysis with untreated core-sampled specimens, found have occurred 4.2 decrease in pH value 9 or lower than that...

This paper examines the dowel-bearing strength of laminated flattened-bamboo lumber (LFBL) perpendicular to grain under influence arrangement method, bolt diameter, and specimen size in accordance with ASTM D5764-97a. There were 360 specimens tested total. As a result test results, it was demonstrated that method flattened bamboo panels significantly affected LFBL. In two groups (bolt direction...

The effect of externally mounted antennae on the energetics of penguins was studied by mounting various antennae on a transducer fixed to a model Magellanic penguin Spheniscus magellanicus to determine drag, run at speeds of up to 2 m s(-1) in a swim canal. For rigid antennae set perpendicular to the water flow, measured drag increased with increasing swim speed. Increasing antenna length (for ...
