Sound Source Localization with Non-calibrated Microphones

We propose a new method for localizing a sound source in a known space with non-calibrated microphones. Our method does not need the accurate positions of the microphones that are required by traditional sound source localization. Our method can make use of wide variety of microphone layout in a large space because it does not need calibration step on installing microphones. After a number of s...

Rapid, High-Level Performance Estimation for DSE using Calibrated Weight Tables

Automated Design Space Exploration (DSE) is a critical part of system-level design. It relies on performance estimation to make rapid decisions. However, since a plethora of design alternatives need to be compared, the run-time of performance estimation itself may pose a bottleneck. In DSE, fastest performance estimation is of essence while some accuracy may be sacrificed. Fast estimation can b...

Calibrated Weighting for Small Area Estimation

Calibrated weighting methods for estimation of survey population characteristics are widely used. At the same time, model-based prediction methods for estimation of small area or domain characteristics are becoming increasingly popular. This paper explores weighting methods based on the mixed models that underpin small area estimates to see whether they can deliver equivalent small area estimat...

Parallel Single-Source Shortest Paths

We designed and implemented a parallel algorithm for solving the single-source shortest paths (SSSP) problem for graphs with nonnegative edge weights, based on Gabow’s scaling algorithm for SSSP. This parallel Gabow algorithm attains a theoretical parallelism of Ω(E/(V lg∆ lgE/D)) in the worst case and Ω(E/(D lgV/D lgE/D lgDelta)with high probability on a random graph. In practice this algorith...
