Meeting the challenges with the Douglas Aircraft Company Aeroelastic Design Optimization Program (ADOP)

An overview of the Aeroelastic Design Optimization Program (ADOP) at the Douglas Aircraft Company is given. A pilot test program involving the animation of mode shapes with solid rendering as well as wire frame displays, a complete aircraft model of a high-altitude hypersonic aircraft to test ADOP procedures, a flap model, and an aero-mesh modeler for doublet lattice aerodynamics are discussed

Practical considerations in aeroelastic design

The structural design process for large transport aircraft is described. Critical loads must be determined from a large number of load cases within the flight maneuver envelope. The structural design is also constrained by considerations of producibility, reliability, maintainability, durability, and damage tolerance, as well as impact dynamics and multiple constraints due to flutter and aeroelasticity. Aircraft aeroelastic design considerations in three distinct areas of product development (preliminary design, advanced design, and detailed design) are presented and contrasted. The present state of the art is challenged to solve the practical difficulties associated with design, analysis, and redesign within cost and schedule constraints. The current practice consists of largely independent engineering disciplines operating with unorganized data interfaces. The need is then demonstrated for a well-planned computerized aeroelastic structural design optimization system operating with a common interdisciplinary data base. This system must incorporate automated interfaces between modular programs. In each phase of the design process, a common finite-element model for static and dynamic optimization is required to reduce errors due to modeling discrepancies. As the design proceeds from the simple models in preliminary design to the more complex models in advanced and detailed design, a means of retrieving design data from the previous models must be established

Sniffer used as portable hydrogen leak detector

Sniffer type portable monitor detects hydrogen in air, oxygen, nitrogen, or helium. It indicates the presence of hydrogen in contact with activated palladium black by a change in color of a thermochromic paint, and indicates the quantity of hydrogen by a sensor probe and continuous readout

Master of Science

thesisTraumatic brain injury (TBI) cases are complex and inherently time sensitive. Clinicians often base treatment decisions upon their individual experiences, training, and many other factors. Prognostic calculators can help enhance the clinician's understanding of the patient's prognosis. Stand-alone, internet-based TBI prognostic calculators exist, including a website developed based on the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT-TBI) [1,2]. An electronic health record (EHR) integrated prognostic calculator that provides the expected probability of favorable and unfavorable outcomes for an individual patient could make treatment planning for TBI patients more efficient, accurate, and standardized, with the ultimate goal of improving patient outcomes. The IMPACT-TBI calculator was integrated with the Epic® EHR and made available to clinicians at the University of Utah Health system in Salt Lake City, Utah. The use of the tool was monitored and analyzed to support the providers and improve care. The calculator was used 346 times over 17 months. Trauma service providers were most likely to use the tool, and there was a significant increase in tool use after a demonstration was given to providers. An IMPACT-TBI prognostic calculator was successfully integrated with a major commercial EHR system. The integration provided insight into strategies for better integration and adoption of advanced clinical decision support tools in the future

Justice Revisited for Sexual Assault Survivors: A Qualitative Analysis of the Initial Phase of Mobile, AL\u27s Promise Initiative

The purpose of the current study was to understand how stakeholders involved in the support of survivors experienced the impact of the preliminary implementation of a Sexual Assault Kits Initiative (SAKI) program.. Interviews were conducted with several participants, including rape crisis advocates, sexual assault nurse examiners, special victim unit detectives, and assistant district attorneys involved in the project called “The Promise Initiative” in Mobile, Alabama. Four major domains—reference to the grant, what contributed to the original problem, stakeholders, and sexual assault—and corresponding core ideas emerged that highlighted both positive and negative experiences stakeholders had with the grant. One of the overarching themes that stakeholders collectively experienced was related to trust or lack thereof within their own capabilities, between other stakeholders, and for the system

Postcolonial Studies and Pantayong Pananaw in Philippine Historiography: A Critical Engagement

This paper offers a platform for a mutually critical imaginary dialogue between two different anti-Eurocentric analytic approaches, Postcolonialism (PC) and Pantayong Pananaw (From-Us, For-Us Perspective, PP). The dialogue foregrounds key areas of engagement between these approaches and allows in the process to revisit a number of vexing issues that interrogate them as well as the nature of an engaged, pro-marginalized scholarship. It suggests that while each approach can profitability learn from the other, it seems that a truly progressive aspiration may be better served by going beyond the current orientations or foci of the two approaches
