A high‐precision frequency estimation algorithm based on multi‐segment signal fusion

IET Radar, Sonar & Navigation, 2023
As the current multi‐segment signal fusion algorithms cannot meet the requirement of high‐precision frequency estimation at different signal‐to‐noise ratios (SNRs), an adaptive fusion algorithm is proposed in this paper.

Recovery efficiencies for Burkholderia thailandensis from various aerosol sampling media

Frontiers in Cellular and Infection Microbiology, 2012
Burkholderia thailandensis is used in the laboratory as a surrogate of the more virulent B. pseudomallei. Since inhalation is believed to be a natural route of infection for B. pseudomallei, many animal studies with B. pseudomallei and B. thailandensis
