An intelligent magnetic tape controller
… at UCT to make use of two nine channel tape drives installed in the undergraduate interfaced to accessed by laboratory for project work. The drives are the department's PDP-11/23 computer, and may be standard operating system directives, as the controller simulates a conventional …

Fabrication of natural and magnetic slippery surfaces
… of LIPS on top of the fabricated texture atop a magnetic tape. Magnetic tapes are no longer widely used and they are extremely difficult to dispose of. In this magnetic tape-based LIPS, we were able to use an external magnet to manipulate droplets on the surface of the magnetic tape. This can …

Dynamic viscoelastic properties of advanced magnetic tapes
… properties of current large digital storage magnetic tape materials, using a custom ultra-low frequency dynamic mechanical analyzer (DMA). Through the correlated effects of frequency and temperature, the long term mechanical properties of the magnetic tape can be simulated and used for …

CRT LIGHT-HEAD FOR AN AUTOMATIC DRAFTING SYSTEM
… core memory, an 1.6M word disc unit, a 9-track magnetic tape unit, a CRT light-head, and a precision flat- bed drafting table.

Dynamic mechanical analysis of magnetic tapes at ultra-low frequencies
… and frequency on the viscoelastic behavior of magnetic tapes, using a custom, ultra-low frequency, dynamic mechanical analyzer. The long-term mechanical and thermal properties of magnetic tapes can be simulated using high temperature and low frequency dynamic mechanical analysis (DMA) …

Monitoring and control of tape production process
… equipment used in the production of open reel magnetic tape for the computer industry.<br/><br/>The thesis discusses the most appropriate method, in the context of the project, for collecting and processing relatively large volumes of data. The project identified process variables which could …

The Revolution Will Be Videotaped: Making a Technology of Consciousness in the Long 1960s
… The technology of recording moving images on magnetic tape, previously of use only to broadcasters, became a tool for artistic expression, psychological experimentation, and political revolution. Video became portable not only materially but also culturally; it could be carried by an …

The Modes of Intervention in Alvin Lucier’s <i>I Am Sitting in a Room</i>
… practice have altered what constitutes the work: magnetic tape was used until 2000 when it was replaced by digital computers. Before 2000 it was rarely performed live; since then it has been performed live frequently. Despite this shift in how the piece circulates, and the fact that most articles …

Beyond the Veil: Revealing the Hidden Qualities of Objects and Spaces through Electroacoustic Audiovisual Experiences
… Schaffer began experimenting with disc and magnetic tape to formulate his theory of musique concrète, helping to create the wider genre of electroacoustic music. This thesis explores how sound installations that combine practice from both visual art and electroacoustic music can reveal …

A towed submersible
… if possible storing the results on a magnetic tape or paper drum or else transmitting the data to the towing vessel. It could be designed so that it was relatively independent of ship speed and self-contained so that it could operate unattended for long periods of the normal …

Resistance of a granular medium to normal impact of a rigid projectile
… and recording the information on an Ampex CP 100 magnetic tape recorder. It was found that penetration of the projectiles into the granular media could successfully be predicted by expressing the resisting forces on the projectile by -M dv/dt = Av² + Cz + D v > v<sub>c</sub> and by -M dv/dt = Bv + …

Human performance evaluations of selected image enhancement/restoration techniques
… to generate the image database for magnetic tape storage. The digitized images were then degraded by blur and noise to simulate various levels of system resolution and system signal-to-noise ratio, respectively. Two experimental tasks were developed to assess the effects of digital …

The development of shaft friction and end bearing resistance for dynamically driven model piles
… discs whilst the transient data was recorded on magnetic tape for later analysis.<br/><br/>A pneumatically controlled rig was designed for driving the piles. The piles were driven from the surface adding sections at selected intervals. Inclinometers were installed in the soil to monitor vertical …

The analysis of acoustic noise in a submerged arc furnace
… The data was recorded on analogue and computer magnetic tape and analyzed at UCT. The analysis was aimed at explaining the operators' theory of the acoustic noise relating to operating conditions of the furnace. This procedure is different from that of Reference 1 in that they did their analysis …

Resonant Bodies: Pauline Oliveros, David Tudor, and Music Mediated, 1950–1980
… engagements with electronic media—including magnetic tape, do-it-yourself circuitry, and biomedical devices—dramatically shaped their approaches to composition, performance, and listening in the Sixties and Seventies, yielding spatialized and participatory relationships to sound that sat …

The Eltro
… pitch-shift and time-compress audio signals on magnetic tape. In all cases, the essence of these devices depended not on one, but typically four tape heads, uniformly placed along a circular drum. By varying the speed of the tape and the rotational speed of the drum, the relative head-to-tape …
