A RATTLE SIGNAL DENOISING AND ENHANCING METHOD BASED ON WAVELET PACKET DECOMPOSITION AND MATHEMATICAL MORPHOLOGY FILTER FOR VEHICLE

A Rattle Signal Denoising and Enhancing Method Based on Wavelet Packet Decomposition and Mathematical Morphology Filter for Vehicle

Buzz, squeak and rattle (BSR) noise has become apparent in vehicles due to the significant reductions in engine noise and road noise.The BSR often occurs in driving condition with many interference signals.Thus, the automatic BSR detection remains a challenge for vehicle engineers.In this paper, a rattle signal denoising and enhancing method is pro

Characterizing barriers to antibiotic stewardship for skin and soft-tissue infections in the emergency department using a systems engineering framework

Abstract Objective: Skin and soft-tissue infections (SSTIs) account for 3% of all emergency department (ED) encounters and are frequently associated with inappropriate antibiotic prescribing.We characterized barriers and facilitators to optimal antibiotic use for SSTIs in the ED using a systems engineering framework and matched them with targeted s
