Modeling Off-Nominal Recovery in NextGen Terminal-Area Operations

Robust schedule-based arrival management requires efficient recovery from off-nominal situations. This paper presents research on modeling off-nominal situations and plans for recovering from them using TRAC, a route/airspace design, fast-time simulation, and analysis tool for studying NextGen trajectory-based operations. The paper provides an overview of a schedule-based arrival-management con...

A Fast Multiplierless Block Transform for Image and Video Compression

COMPRESSION Trac D. Tran ECE Department, The Johns Hopkins University, Baltimore, MD 21218 [email protected] ABSTRACT In this paper, we present a family of fast biorthogonal block transforms called binDCT that can be implemented using only shift and add operations. All transforms are based on a VLSI-friendly lattice structure which robustly enforces both linear phase and perfect reconstruction ...
