Static Optimization of Conjunctive Queries with Sliding Windows Over Infinite Streams
We define a framework for static optimization of sliding window conjunctive queries over infinite streams. When computational resources are sufficient, we propose that the goal of...

Test-access mechanism optimization for core-based three-dimensional SOCs
— Test-access mechanisms (TAMs) and test wrappers (e.g., the IEEE Standard 1500 wrapper) facilitate the modular testing of embedded cores in a core-based system-on-chip (SOC). Su...
