Dynamic model of the interface reactions in an aircraft bomb rack due to an external store

In today\u27s downsizing environment, more demands than ever are being placed on aircraft flight test programs. To compensate for shrinking budgets and increased requirements, new and more versatile test techniques and data processing systems must be developed. Standard flight test procedures must be reexamined and optimized to maximize the availability of the test asset while processing the collected data more quickly and at a lower cost.;This research demonstrated the ability to predict the reaction loads transmitted to an aircraft bomb rack due to the inertial forces acting on an external store. These load calculations typically require lengthy test programs with strain gage and accelerometer instrumentation placed on the store, suspension equipment and rack interface points. Instrumented testing procedures are cost prohibitive and time consuming, requiring much pre-flight and post-flight work to instrument the test articles and reduce the data, respectively. This research focused on calculating the interface reactions relying only on store mass properties, accelerometer data and geometry, all of which can be collected at minimal effort and cost while allowing real-time data reduction.;Equations were developed from classical theory and the accuracy of the data was proven with actual flight test information. A full-scale static ground test provided data for model improvement and verification. Flight test data for final validation were primarily accumulated during a carrier suitability flight test program conducted at the Naval Air Warfare Center, Patuxent River, Maryland on a fully instrumented F-14, BRU-32/A bomb ejector rack and a GBU-24B/B 2,000-lb. bomb.;In the 300 milliseconds following arrestment, forces and moments up to 15,000 lbs. and 150,000 in-lbs., respectively, were calculated at the store CG. Compared to the measured data, very good agreement was found in form and magnitude for all calculated interface reactions. Critical lug and swaybrace rod reactions averaged less than 7% and 9% absolute error, respectively. Swaybrace rod and vertical lug reactions that were less than 2,000 lbs. and 5,000 lbs., respectively, were considered non-critical and in the noise of the test

African Regional Organizations And Democracy

Instability and political repression are two reasons why many states in Africa are unable to develop. African regional organizations have the potential to encourage democracy, stability and development within their regions if they have the right tools. Using case studies of two major interventions by African regional organizations this thesis will determine what those tools may be. Both the intervention of ECOWAS into Liberia and the SADC into the DRC were rife with problems but they were able to bring some stability and even democracy to states in crisis. This thesis finds that African regional organizations can promote democracy and stability, but the focus is always on stability for the region. With strong institutions and mandates, policy agreement and strong leadership, African regional organizations can bring stability, development and even democracy to their regions

Librarian Leadership in Open Education Resources: Implementing and Supporting Innovation in Community Colleges

The purpose of this narrative inquiry study was to describe the lived experiences of librarians and how they provided support and innovation for community college OER programs. Examining the experiences of librarians as innovators sought to understanding how best practices developed for OER programs. It further sought to examine how participants approached social interactions, inter-departmental collaborations, and systemic organizational structures to support and implement OER programs. These narratives provided understanding to how institution-wide initiatives were developed. The following foundation question guided the research: What are the experiences of librarians through the challenges, barriers, and successes of implementing and supporting OER innovation? The focus of this study was librarians that work at community colleges and that had engaged with OER program implementation. Although some of the librarians in this study had worked in 4-year institutions, their innovative OER program experiences emerged at community colleges. Through the lens of narrative inquiry, this research provided rich and detailed stories of the participant’s experiences. The study findings indicated the scope and responsibilities of OER librarianship. It further identified barriers to successful OER program implementation such as lack of authority within OER librarian positions for needed initiative processes. The results of this research provided insight into how initiatives were implemented, and how innovators navigated organizational structures to develop OER programs

The development of a model for participatory goal setting in private educational institutions

This study was undertaken to explore the process of goal setting in organizations in general, and private educational institutions in particular, in an effort to determine the potential usefulness of participation as a goal setting method, and to develop a model for participatory goal setting. The basic research method used was the survey of literature, with attention to the literature of organizational goals, the literature of private educational institutions, and the literature of participation in organizations and particularly in educational institutions

Landschaftswandel - landscape change

Unter dem Motto „Landschaftswandel – Landscape Change“ haben der LSGL, das FZLB, das BLDAM, und die VEM im Juni 2009 ein gemeinsames Symposium an der BTU Cottbus organisiert und ausgerichtet. Um dem wachsenden wissenschaftlichen, politischen und gesellschaftlichen Interesse an dieser Thematik Rechnung zu tragen, sind in diesem Band ausgewählte Beiträge von Referenten des Symposiums veröffentlicht. Die Beiträge zeigen die Breite der am Thema „Landschaftswandel – Landscape Change“ beteiligten Disziplinen, Akteure und Regionen: vom Bergbaubetreiber über die Botanik zur Archäologie und der physischen Geographie, von der Lausitz über Bayern bis nach Griechenland

OER Collaboration Between Colleges

In an ongoing effort to bridge OER collaboration between colleges, Blue Mountain CC, Columbia Gorge CC, and Klamath CC collectively worked on the adoption of several transfer courses. We worked with faculty teams who adapted OER for courses in sociology and US history sequences, and a communication course. Through cross-collaboration these teams adapted OER to fit their own needs while also adding OER resources accessible statewide. We will share how we developed bridges, managed collaboration, and tried to guide OER adaption in a collaborative environment

Direction sensitive analysis of higher order jump discontinuities along circles on the sphere

AbstractIn recent years, scale-discretized directional wavelets and second-generation curvelets have been introduced on the unit sphere, yielding directional and localized polynomial frames for band-limited signals. In this paper, we show that these functions are able to detect the positions and orientations of all higher order jump discontinuities which lie along circles on the 2-sphere. Specifically, we prove upper and lower estimates for the magnitude of the corresponding inner products when the analysis function is concentrated in the neighborhood of such a singularity. Although similar results already exist in certain two-dimensional settings, this paper is the first one to consider frames and signals that are given on the 2-sphere. As a side product of our investigations, we also develop a new localization bound as well as an explicit formula for the auto-correlation function for second-generation curvelets. </jats:p
