An Axiomatic Approach to Metareasoning on Nominal Algebras in HOAS
We present a logical framework Υ for reasoning on a very general class of languages featuring binding operators, called nominal , presented in higher-order abstract syntax (HOAS)....

Multichannel Autofocus Algorithm for Synthetic Aperture Radar
The autofocus problem in synthetic aperture radar (SAR) is considered, where phase errors in the acquired signal data result in imagery that is improperly focused. We present a ne...
