We construct new twisted Euler polynomials and numbers. We also study the generating functions of the twisted Euler numbers and polynomials associated with their interpolation functions. Next we construct twisted Euler zeta function, twisted Hurwitz zeta function, twisted Dirichlet l-Euler numbers and twisted Euler polynomials at non-positive integers, respectively. Furthermore, we find distrib...

The purpose of this study was to determine the environmental stability and life expectancies of magnetic media used with certain high density, digital recording tape systems, specifically the IBM 3590 and both Quantum’s Digital Linear Tape (DLT) and Super DLT products. The goal of the study was to compare the tape stabilities and life expectancies of the corresponding tape media and tape storag...

In the mid-1980s, tape storage appeared to be heading toward the graveyard. Storing information on large reels of tape that had to be manually mounted was expensive, inefficient, and prone to human error. In addition, competition from hard disk drives (HDDs) was growing. Data access on HDD was faster because the data was stored in a manner for rapid random access, not linearly as on tape, and H...

Situated at the bottom of vacuum vessel, divertor extracts heat and ash produced by fusion reaction, minimizes plasma contamination, protects surrounding walls from thermal neutronic loads. The vertical targets are designed to be able for up 20 MW/m2 high flux. It is a great ordeal both material performance cooling ability. Critical flux margin very crucial during design divertor. ANSYS FLUENT ...

Characterization of the exact critical current density (Jc) and stress values in twisted superconducting tapes plays an important role for analyzing their magnetic, thermal, mechanical behaviors. In study, a model based on artificial neural network (ANN) is introduced to estimate electro-magneto-mechanical characteristic different tapes. For this purpose, magnetic flux density, temperature, str...

Both magnetic wire and acetate-based magnetic tape were used in the audio industry. Welsh and Lukoff [lj describe the early use of metal tape for digital magnetic recording. Acetate-based tape was used for digital recording by Raytheon at a relatively low tape velocity, as reported by Bloch [2]. At IBM it was decided to pursue an acetate-based plastic magnetic tape for computer input,‘ output b...
