Flutter optimization in fighter aircraft design

The efficient design of aircraft structure involves a series of compromises among various engineering disciplines. These compromises are necessary to ensure the best overall design. To effectively reconcile the various technical constraints requires a number of design iterations, with the accompanying long elapsed time. Automated procedures can reduce the elapsed time, improve productivity and hold the promise of optimum designs which may be missed by batch processing. Several examples are given of optimization applications including aeroelastic constraints. Particular attention is given to the success or failure of each example and the lessons learned. The specific applications are shown. The final two applications were made recently

Reference Revitalization and Roving Reference: Are the Reference Desk and Print Reference Sources Passé?

Print reference sources and references desks are still vital parts of reference service in some libraries, while in others innovative models such as roving reference and learning commons thrive. While undergraduate students’ preferences and usage has shifted from print to electronic, students still need to learn the application of metacognitive thinking skills in library research. Updating how reference is delivered to accommodate students’ emphasis on mobility and expectation of access to information has led to revitalizing reference collections, reconfiguring space as learning commons and roving reference as solutions at Taylor University and Palm Beach Atlantic University, while Whitworth University retains a more traditional configuration to meet student research needs
