| A logical framework and its implementation should serve as a flexible tool for specifying, simulating, and reasoning about formal systems. When the formal systems we are interested in exhibit state and concurrency, however, existing logical frameworks fall short of this goal. Logical frameworks based on a rewriting interpretation of substructural logics, ordered and linear logic in particular, can help. To this end, this dissertation introduces and demonstrates four methodologies for ... |

| Modern phased array radar uses multifunctional subarray antennas in a distributed fashion. Distributed subarrays (DSAs) have the advantages of more efficient scheduling of track and search functions, rapid steering capability, decreased complexity in digital beamforming, and better angular resolution. However, the disadvantage of DSAs are the extra grating lobes caused by large subarray spacing, which can cause ambiguities in angle measurements and excess background clutter. A possible approach to suppressing ... |
