MSc (Med), Emergency Medicine, Faculty of Health Sciences, University of the Witwatersrand, 2009 / Objectives: to establish the accuracy and reliability of a new device, the PAWPER tape (PT), for length-based weight estimation in children; to assess whether the addition of a measure of body habitus could improve the accuracy of weight estimation; and to compare the performance of the PT with that of the Broselow tape (BT). Design: prospective, cross-sectional, descriptive study. Setting: emergency departments (EDs) of two Johannesburg private hospitals. Patients: children aged from 1 month to 12 years who were not in need of emergent medical management. Methods: each child had their weight estimated by both the BT and the PT (which included a method for adjusting the predicted weight according to body habitus). These predicted weights were then compared against measured weight to determine the bias and precision of the estimation techniques. Main Results: the PT performed as well or better than the BT in every analysis performed. The mean percentage error (MPE) was -3.8% vs 0% and the absolute MPE was 9.1% vs 4.5% for the BT and PT respectively (p<0.0001). The BT predicted weight to within 10% of actual weight in 63.6% of children and the PT in 89.2% (p<0.0001). The difference between the performances of the BT and PT was most pronounced in children >20kg, and in children above or below average weight-for-length. Conclusions: The PT was a reliable weight estimation device that performed well in this population, often with a greater degree of accuracy than the BT. The inclusion of an appraisal of body habitus in the methodology considerably improved the accuracy of weight estimation.

Thesis (M.S.)--Catholic University of America. / Includes bibliographical references.

This thesis describes a system to allow a mass storage device to be installed in a position remote from the computer system which controls it. This system is intended to allow undergraduate students in the Electrical Engineering department 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 computer peripheral. The system consists of an SA-Bus based tape transport controller which interfaces to the host computer system via a serial line. The following hardware was designed and built specifically for this system : 1. A CPU card based on the in Tel 80188 microprocessor, incorporating high speed DMA (direct memory access) channels and two interrupt driven serial lines. 2. A timing and control module for the tape transports. This consists of two SA-Bus cards. Two sets of software were written for the system. These are the following : 1. Software to operate the tape controller. This consists of six modules written in Pascal-86 and 8086 assemblers. 2. Software to allow the PDP-11/23 to control the tape drives. This is in the. form of an RSX-11 device driver written in PDP-11 assembler. To allow the particular to proposed local system allow area highly modular form. to be easily the system to network) , the upgraded in the future (in be incorporated into UCT's software was written in an addition to being controlled by a host system in remote mode the tape controller also has the ability to perform a variety of operations in local mode. These include the ability to copy and erase tapes, as well as a comprehensive set of diagnostic functions. When in local operations mode the controller is menu driven, making its use by persons who are not familiar with it quick and easy.

This master’s thesis deals with ways of lamination of ceramic tapes prepared by gel–tape casting method. The thesis is divided into two parts. The first part, a literary recherche, describes methods of production of thin ceramic layers. The main focus is on the tape casting method. The second, experimental, part of the thesis describes the preparation of ceramic suspensions, the fabrication of thin ceramic layers by gel–tape casting method, the preparation of laminated bodies from thick-walled discs and laminated tapes and it also shows a possibility of creating of ceramic layers by the spin coating method used on polycrystalline ceramic substrate.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / Veda Incorporated has developed an airborne instrumentation recorder for a major commercial aircraft manufacturer. The recorder was developed for use in the aircraft company's Portable Airborne Digital Data System (PADDS), a small scale data acquisition and monitor system used for flight testing. The recorder is designed around an off-the-shelf 8mm tape drive, the Exabyte 8505. It records asynchronous, variable-rate data in a proprietary 24-bit recording format, and allows the data to be played back in real time. Its RS-422 control interface is designed to imitate the recorder used in the company's large scale data acquisition system, the Ampex DCRSi-II. Special provisions allow it to withstand the environment of an airplane's EE bay.

There are many parameters that significantly affect the electrical performance of ceramic-core superconducting composite wire and tapes, which remain ambiguous and require more labor on their optimization. BSCCO 2212 has not been paid the attention and investment it deserves. In this regard, all optimization efforts were made for BSCCO 2223. In our work, a practical and inexpensive manufacturing method, thermally and mechanically optimized for Pb doped BiSrCaCuO 2212 superconducting multifilament (38 filaments) wires and tapes, was successfully employed. Optimized parameters can be classified under material, mechanical (deformation) and heat treatment (thermal) subgroups. Parameters involved with materials included investigation of deformation behavior of two different sheath metals; pure silver and 0.02% magnesia dispersion reinforced silver alloy. Pb doped BiSrCaCuO 2212 ceramic superconductor powder, the other source of material related parameters, was synthesized following the "Thermal Co-decomposition or Wet Mix" method. Fabrication of mono and multifilament wires with Oxide Powder in Tube (OPIT) method followed next. Optimization of drawing deformation was practiced to achieve the best ceramic grain alignment and smoother ceramic powder core/metal sheath interface in order to avoid "sausaging" in wires. Rolling of the wire products into tapes by following different deformation regimes was the other manufacturing stage of the project. Variable and constant reduction-per-pass deformation paths were employed to reveal their effects on our composites with distinct sheath material and filament formation. The search for the best (optimum) heat treatment schedule for our Bi2212 superconductor composites, a modified version of "step solidification partial melting", was employed successfully. A solution through tried recipes for the bubbling problem that occurred with our tapes was also addressed. Electrical performance tests of fully reacted wires were carried out in our laboratory and very promising results were attained.
