Spacelab interface development tests. Software description
The software requirements for the Spacelab Interface Development Tests are described. The software operates in two modes. The multiplexer-demultiplexer mode transmits operator-controlled information to the Spacelab. The pulse coded modulation (PCM) mode records and displays operator selected PCM data for visual analysis
Improving utility in the Marine Corps depot level maintenance program
MBA Professional ReportThe Marine Corps operates a Depot Level Maintenance Program (DLMP) to support the continued operation of principal end items. Principal end items require periodic induction into the DLMP. This maintenance consists of major systems overhauls aimed at extending the life cycle of the principal end item. The frequency of these inductions is different for each end item. The number of systems requiring induction into Depot Level Maintenance in a given year is always greater than the funding available in that year resulting in a constraint. The Marine Corps has attempted to optimize the utility received from the DLMP through the use of a model that takes a number of variables into consideration resulting in a schedule for enditems to be inducted into the DLMP. This model makes the most efficient use of available funding by creating the largest increase in readiness reporting possible given the constrained budget. The changing operational requirements in light of current conflicts and future operations tempo have made the current DLMP process problematic.http://archive.org/details/improvingutility109459886Major, United States Marine CorpsCaptain, United States Marine CorpsApproved for public release; distribution is unlimited

Floppy disk utility user's guide
The Floppy Disk Utility Program transfers programs between files on the hard disk and floppy disk. It also copies the data on one floppy disk onto another floppy disk and compares the data. The program operates on the Data General NOVA-4X under the Real Time Disk Operating System (RDOS)
Design and commissioning of a timestamp-based data acquisition system for the DRAGON recoil mass separator
The DRAGON recoil mass separator at TRIUMF exists to study radiative proton
and alpha capture reactions, which are important in a variety of astrophysical
scenarios. DRAGON experiments require a data acquisition system that can be
triggered on either reaction product ( ray or heavy ion), with the
additional requirement of being able to promptly recognize coincidence events
in an online environment. To this end, we have designed and implemented a new
data acquisition system for DRAGON which consists of two independently
triggered readouts. Events from both systems are recorded with timestamps from
a MHz clock that are used to tag coincidences in the earliest possible
stage of the data analysis. Here we report on the design, implementation, and
commissioning of the new DRAGON data acquisition system, including the
hardware, trigger logic, coincidence reconstruction algorithm, and live time
considerations. We also discuss the results of an experiment commissioning the
new system, which measured the strength of the
keV resonance in the NeNa radiative proton
capture reaction.Comment: 11 pages, 7 figures, accepted for publication in EPJ A "tools for

CDEV-NT: Porting the Control Device Interface to Windows NT
In recent years the rapid increase in processing power of the personal computer has made it a significant competitor to high-end workstations for accelerator control and experimental physics applications. When the decreasing price of the PC and the availability of inexpensive commercial software is also considered, NT becomes a very attractive alternative to traditional UNIX systems. In order to simplify the integration of Personal Computers into our operating environment, we have ported the Control Device (CDEV) Interface to Windows NT. By supporting CDEV on this platform, we can provide routine access to our existing control system. Additionally, CDEV allows us to create an interface from our UNIX workstations to Windows NT applications (such as databases) that are significantly less expensive on the PC. This paper details the pitfalls we encountered during the software migration and will provide a direct comparison between the performance of CDEV applications on UNIX and NT. P articular attention is paid to network performance, which represents most of the overhead of this transition

Preparedness planning for pandemic influenza among large US maternity hospitals
The objective of this investigation was to determine the state of pandemic influenza preparedness and to delineate commonly reported challenges among a sample of larger US national maternity hospitals. This was done given the recent emphasis on hospital disaster planning and the disproportionate morbidity and mortality that pregnant women have suffered in previous influenza pandemics. An internet-based survey was sent to all 12 members of the Council of Women's and Infants’ Specialty Hospitals. Questions addressed hospital demographics and overall pandemic preparedness planning, including presence of a pandemic planning committee and the existence of written plans addressing communications, surge capacity, degradation of services, and advance supply planning. Nine of 12 (75%) hospitals responded. All had active pandemic planning committees with identified leadership. The majority (78%) had written formal plans regarding back-up communications, surge/overflow capacity, and degradation of services. However, fewer (44%) reported having written plans in place regarding supply-line/stockpiling of resources. The most common challenges noted were staff and supply coordination, ethical distribution of limited medical resources, and coordination with government agencies. In conclusion, the majority of the Council of Women's and Infants’ Specialty Hospitals maternity hospitals have preliminary infrastructure for pandemic influenza planning, but many challenges exist to optimize maternal and fetal outcomes during the next influenza pandemic
