The mathematical modeling of the acoustic wave propagation in seawater is the basis for realizing goals such as, underwater communication, seabed mapping, advanced fishing, oil and gas exploration, marine meteorology, positioning and explore the unknown targets within the water. However, due to the existence of various physical phenomena in the water environment and the various conditions gover...
We report on tunnelling magnetoresistance (TMR), current–voltage (IV) characteristics and low-frequency noise in epitaxially grown Fe(1 1 0)/MgO(1 1 1)/Fe(1 1 0) magnetic tunnel junctions (MTJs) with dimensions from 2 2 to 20 20mm. The evaluated MgO energy barrier (0.5070.08 eV), the barrier width (13.170.5 Å) as well as the resistance times area product (771MOmm) show relatively small variatio...
Visual obstruction, but not moderate traffic noise, increases reliance on heterospecific alarm calls
Abstract Animals rely on both personal and social information about danger to minimize risk, yet environmental conditions constrain information. Both visual obstructions background noise can reduce detectability of predators, which may increase reliance information, such as from alarm calls. Furthermore, a combination auditory constraints might greatly because the loss one source cannot be comp...
Figure 1: Effect of annealing on tunneling magnetoresistance ratio. Low-noise magnetic sensors (noise spectral density ~ pT/Hz1⁄2) based on magnetic tunnel junctions can be integrated to provide unprecedented clinical information, viz., room-temperature magnetocardiography [1]. The sensors comprise a tunnel junction, a “flux concentrator,” and a mechanism for chopping the input signal with a mi...
We present a model-based noise compensation algorithm for robust speech recognition in nonstationary noisy environments. The effect of noise is split into a stationary part, compensated by parallel model combination, and a time varying residual. The evolution of residual noise parameters is represented by a set of state space models. The state space models are updated by Kalman prediction and t...
