ADVANCED DATA ACQUISITION AND PROCESSING SYSTEMS (ADAPS) UPDATE

Hines, Dennis O., Rhea, Donald C., Williams, Guy W. 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The rapid technology growth in the aerospace industry continues to manifest itself in increasingly complex computer systems and weapons systems platforms. To meet the data processing challenges associated with these new weapons systems, the Air Force Flight Test Center (AFFTC) is developing the next generation of data acquisition and processing systems under the Advanced Data Acquisition and Processing Systems (ADAPS) Program. The ADAPS program has evolved into an approach that utilizes Commercial-Off-The-Shelf (COTS) components as the foundation for Air Force enhancements to meet specific customer requirements. The ADAPS program has transitioned from concept exploration to engineering and manufacturing development (EMD). This includes the completion of a detailed requirements analysis and a overall system design. This paper will discuss the current status of the ADAPS program including the requirements analysis process, details of the system design, and the result of current COTS acquisitions.

A Case for Sustainable Off Campus Student Housing

O'Neill, Lynndsay 11 December 2015 (has links)
Sustainable Built Environments Senior Capstone Project / Apartment communities in the arid southwest in Tucson and Tempe, Arizona and Sand Diego, California within three miles of U of A, ASU, and SDSU with over 500 residents were evaluated based on the sustainability features they provided. An ANOVA test of significance was used to determine a correlation between the number of sustainability features provided and the occupancy rate of the community.

Essays on the value of academic patents and technology transfer/ Essais sur la valeur des brevets universitaires et le transfert de technologie

Sapsalis, Eleftherios 12 June 2007 (has links)
Around the world, knowledge and technology transfer have moved to the forefront of attention in economic, social and industrial policy. As the origins of future development increasingly derives from innovation, attention is paid more and more to non-traditional sources that have the potential to become the basis for creation of new businesses or the catalyser for the rejuvenation of old ones. Among those sources, we find university. These last years, academic patents have been one of the emerging phenomena witnessing the growing evolvement of university in the innovation process. The aim of this doctoral dissertation is to analyse the transfer of technology from university to industry through the analysis of patents. This work pursuits a threefold approach. First, it intends to analyse which characteristics determine the propensity of a university to get involved in technology transfer and more specifically to apply for a patent. Second, it disentangles the underlining value determinants of the patents to decode the value of academic patents and to identify the research processes that are leading to the most valuable inventions. Finally, it investigates the relevancy of academic patenting for innovation in general and wonders if on the long run, such practices could put innovation at risk.

Vertex radius measurement of an off-axis parabola with a three-ball spherometer

Dominguez, Margaret Z., Li, Jianxin, Zhou, Ping, Burge, James H. 23 December 2016 (has links)
A spherometer is often used to precisely measure the radius of curvature of a spherical surface. It can also measure the vertex radius of a more complex surface such as an off-axis parabola (OAP). This paper provides a reliable algorithm to find the vertex radius of an OAP by solving a few equations based on the test geometry. This algorithm can also be easily expanded to any conic surface with high-order aspheric coefficients. The algorithm was verified by measuring an 8-inch diameter OAP and comparing the results with its known prescription. Results show good agreement. An example of measuring the vertex radius of a 4-m diameter OAP is also presented. In addition to this, a calculation was done to show that the coma and astigmatism are independent of the clocking of the spherometer on the optic.

Development of a low cost cook-off test for assessing the hazard of explosives

Frota, Octávia January 2015 (has links)
A low cost Cook-Off experimental facility has been established to provide a convenient method of ranking explosives in their response to Cook-Off by the time to event under two widely different heating rates and at two different scales. This thesis describes the literature review undertaken as preparation for the purposed study and all the experimental work developed comprising the design of the trials vehicles, the demonstration of their suitability for Fast and Slow Cook-Off trials with confined explosive systems, the preparation of the samples and test vehicles to be trialled as well as the set-up of adequate facilities to undertake the scheduled firing programme. Results are reported for Cook-Off tests on TNT, RDX, and their mixtures. The emphasis of the study is on time to event, and temperature at event, and in addition a qualitative assessment of the violence of the event was made by examination of the fragments of the vehicles, although it is accepted that the relatively light and low cost design of the vehicle may lead to variable confinement in the early stages of the explosive event, and hence to a wider spread of responses than would be obtained from a more heavily confined and more costly vehicle. The test vehicles give results, which differentiate between the various explosives and explosive mixtures trialled and between the scales. More experiments are required to establish the reproducibility of the measurements. The design of the equipment makes this a relatively inexpensive undertaking. The experiment was modelled using published kinetic data, but the calculated time to event differed from that observed to different extents at the two scales. It is hypothesised that the mechanism may change over the prolonged heat soaks and that quantitative scaling is not possible with the available information. Further work is also suggested using a different type of Cook-Off test vehicle, which will in our opinion reduce even further the cost of Cook-Off testing, due to reduction in man-hours of preparation involved and manufacture cost of the Cook-Off test vehicles, and consequently of ranking of explosives.

Improving Hand-Off Communication from Primary Care to Emergency Department

Cobbs, Brian W., Cobbs, Brian W. January 2017 (has links)
A hand-off represents the transfer of patient information and care responsibility between a sending and receiving provider. Hand-offs occur in single locations such as inpatient wards and across care settings like from primary care offices to emergency departments. This care transition quality improvement (QI) project was created to improve patient hand-off communication from a primary care office to a hospital based emergency department within the greater Phoenix, AZ metropolitan area. No uniform hand-off process existed before the QI project. The purpose of the QI project was to demonstrate process necessary to achieve desired outcomes, in this case, a superior patient hand-off. The QI project goal was to develop a standardized hand-off protocol and tool. The aim of this QI project was to replace existing hand-off methods with a formalized new hand-off process and tool used during care transition from a primary care office to an emergency department. QI project methods followed two (2) plan-do-study-act (PDSA) cycles involving QI team meetings and end-user feedback that iteratively led to the adoption of a standardized hand-off process and tool. PDSA cycle one identified the best handoff tool. PDSA cycle two established an efficient process for conducting hand-offs. The new hand-off tool consistently demonstrated superior information transfer. Program participant satisfaction increased and was reflected by positive feedback as most nurses and doctors embraced the new process.
