Rethinking the “Unthinkable”: Defining Closure in Brahmsʼs Sonata Forms

Does current research on the Classical sonata apply to Romantic modifications of the form? Although Hepokoski and Darcy amply demonstrate the increasing frequency of ambiguous or missing points of sectional closure, they do not address the possibility that this " extreme " and " unthinkable " Classical technique might not bear the same weight in the Romantic sonata. Even a cursory examination o...

On Sampling-Criteria Induced Oscillations

Limit oscillations are investigated when the associated sampling instants are generated from difference of amplitudes sampling criteria. The uncontrolled object is assumed to be linear and time invariant while there is a feed-forward consisting of an adaptive sampling law which generates the sampling instants as the absolute value of the incremental tracking error related to its previously samp...

Performance Parameters I: Defining Performance Criteria

Today’s ultrasound imaging systems produce better images and display more information than it was possible to display 30 years ago. Similarly, performance criteria for ultrasound imaging systems and the tools used to make these measurements have evolved, and have become more complex. This presentation will informally discuss a few examples of the evolution of ultrasound imaging systems and perf...
