Underwater Wireless Sensor Networks (UWSNs) are expected to support a variety of civilian and military applications. Sensed data can only be interpreted meaningfully when referenced to the location of the sensor, making localization an important problem. W ...
Modified lead titanate of the base composition (Pb,Ca)Ti-(Co,W)O3 + 0.01 mol % MnO was doped with 2 to 6 mol % strontium and barium to increase the dielectric constant, K, while preserving a high piezoelectric anisotropy (d33/d31). K was increased above 50 ...
Nowadays, requirements for acoustic treatments in rooms are ever more demanding in terms of performance and compactness. A recurring issue in closed spaces is the occurrence of standing waves and acoustic interferences at low frequencies. These unwanted ph ...
We study an acoustic tomography problem and propose a new inversion technique based on sparsity. Acoustic tomography observes the parameters of the medium that influence the speed of sound propagation. In the human body, the parameters that mostly influenc ...
This paper studies the problem of sound source localization in a distributed wireless sensor network formed by mobile general pur- pose computing and communication devices with audio I/O capa- bilities. In contrast to well understood localization methods b ...
