Aluminum and its alloys have a lot of industrial applications due to their appropriate physical and chemical characteristics. However, those present a modest mechanical performance. One method to improve its strenght is the addition of hard insoluble particles as: carbides (Al4C3, TiC), oxides (Al2O3) or nitrides (TiN, AlN), which can difficult the dislocation movement at atomic level, resultin...
Air-lubricated foil bearings are used in a variety of applications such as turbomachinery, journal bearings, dentistry equipment, etc. [1–3]. One of the most intricate applications of air-lubricated foil bearings can be found in magnetic tape drives [4], where a magnetic tape moves over a read/write head and tape drive components such as guides (stationary) and rollers (rotating). Friction is a...
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...
Modification of irrigation scheduling and management improvement of irrigation systems are two essential factors that have significant impact on agricultural water use efficiency. Therefore, a field experiment was conducted to evaluate the effect of tape drip irrigation (T) and furrow irrigation systems (S) under different irrigation regimes on yield and yield components of soybean in growing s...
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...
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...
Background: Today, different types of tapes used for prevention and treatment of chronic inversion ankle sprain. The purpose of current study was to investigate the effect of two different tapes (white and Kinesio tape) on peak knee anterior shear force during landing after the jump among elite volleyball players with chronic inversion ankle sprain. Methods: In this semi- experimental study,...
