Introduction Lateral tape motion (LTM) is the time-dependent displacement of magnetic tape perpendicular to the tape transport direction. Lateral tape motion may cause track misregistration between the read/write head and a previously written track, thereby limiting the recording density that can be achieved [1]. Currently, the track density of typical magnetic tape drives is approximately 40 t...

Aging and sun exposure are the leading causes of skin cancer. It has been shown that epigenetic changes, such as DNA methylation, well established mechanisms for However, large scale data acquisition is a problem it relies mostly on invasive biopsies. Here we present method non-invasive sample collection using tape-stripping analysis. We compared matched shave biopsies tape stripping samples to...

The sources of lateral tape motion in a tape drive are reviewed. Currently used measurement methods and models for lateral tape motion are analyzed and compared. The effect of roller run-out, tape edge contact, and tape tension transients on lateral tape motion is discussed. A dual stage actuator tape head is investigated to improve track-following capability and increase the track density on a...

In [2] it has been shown that infinitary strong normalization (SN∞) is Π11-complete. Suprisingly, it turns out that infinitary weak normalization (WN∞) is a harder problem, being Π12-complete, and thereby strictly higher in the analytical hierarchy. We assume familiarity with infinitary term rewriting; we further reading we refer to [5,4]. 1 Infinitary Strong Normalization and Reachability Defi...

The resistive superconducting fault current limiter is well known for its simple structure and outstanding current-limiting effect, it broadly applied in power grid systems. second-generation high-temperature superconductor (HTS) tape, of higher structural strength greater room-temperature resistance, suited application limiters. quenching caused by overcurrent the HTS tape a complexed coupling...

The mechanics of the "tape" over a flat-head is investigated. It has been recently shown that a thin, flexible tape, traveling over a flat recording head under tension contacts the head over the central area of the head. This phenomenon is due to the selfacting, subambient foil bearing effect. In this paper, as a first order of approximation, a simplified system is analyzed; where a uniform sub...

Introduction High frequency lateral tape motion (LTM) is a problem in tape technology that limits track density in a tape drive. To reduce high frequency LTM, it is important to identify all sources of lateral tape motion. The most important sources of high frequency LTM are edge contact between tape and tape drive components, non-repeatable roller axial run-out, air induced flutter and tape te...

Today large amounts of data are stored on tertiary storage media such as magnetic tapes and optical disks. DBMSs typically operate only on magnetic disks since they know how to maneuver disks and how to optimize accesses on them. Tertiary devices present a problem for DBMSs since these devices have dismountable media and have very diier-ent operational characteristics compared to magnetic disks...

Assessing changes in upper extremity limb volume during lymphedema therapy is important for determining treatment efficacy and documenting outcomes. Although arm volumes may be determined by tape measure, the suitability of circumference measurements to estimate hand volumes is questionable because of the deviation in circularity of hand shape. Our aim was to develop an alternative measurement ...
