Maneuvering target tracking in wireless sensor networks (WSNs) has been a prominent research topic over the past twenty years. In many situations, WSNs are vulnerable to natural or man-made interference, resulting uncertainty problems. this paper, we propose an information-quality-based selection method with estimation feedback for maneuvering uncertain WSNs. First, based on Generalized Pseudo-Bayesian estimator of first order (GPB1) and unscented information filter (UIF), GPB1-UIF algorithm...
Due to communication delays and other limitations of wireless sensor networks (WSNs), asynchronous selection is necessary for target tracking. However, not much work has been formulated this problem. Inspired by the concept data freshness, article applies age information (AoI) tracking in presence random delays. In regard, we formulate several AoI-based designs measure value measurements. The first formulation minimizes time-average AoI achieve enhanced performance, second attempts set an...
A distributed multi-sensor control method is presented for multi-target tracking. The problem formulated as auctioned partially observed Markov decision processes (auctioned POMDPs), which a tractable approach to approximate the solutions in manner. To ensure adequate coverage of system, sparsity-promoting objective function also designed reduce overlapping sensing areas, balancing tradeoff between reward and sensor coverage. Simulation results demonstrate that proposed achieves comparable...
In this paper, a whole-field and high-speed optical three-dimensional (3D) shape measurement for the vibration pattern of drumhead based on Fourier Transform Profilometry (FTP) is presented verified by experiment. A projected sinusoidal fringe surface measured dynamically deformed with membrane grabbed camera. The 3D deformation at each sampling instant can be recovered from demodulating phase obtained sequence patterns. Chinese drum has been rate (1,000 fps) standard deviation (0.075 mm)....
Underwater laser imaging is of great significance in underwater search and marine science, <i>etc</i>. However, traditional often poor quality with noises blurs, moreover, the resolution image also low. In order to obtain clear images high quality, here, we have designed a range gated system realized an restoration approach. this paper, based on introduction algorithm, experiment established by setting under water lake capture targets. With proposed approach, could be retrieved which proves...
Based on the sliding mode control theory and Lyapunov stability theory, a finite-time convergence guidance law with attack angle constraint is proposed in this paper. As initial trajectory of missile which apply too curved. To reduce fuel consumption missile, damping term utilized to design surface function. deal chattering phenomenon motion process, guarantee speed as well, double power combination function reaching adopted constrain approaching process. Comparing traditional law, paper...
The application of intelligent inspection to the online ceramic tile surface defects not only ensures stability product quality but also reduces cost labor for enterprises. Existing detection methods often achieve good results in known background textures, however, its false rate increases dramatically, and practicality is greatly reduced when there are unknown textures or with similar characteristics textures. This paper proposes a non-defective defective samples synchronous comparison...
An optical technique is carried out in our lab which uses velocity interferometers to measure the shear-wave on surface of a sample. By planar impact one stage gas gun with 57 mm diameter and anisotropy Y-cut quartz, combining pressure-shear loading Ly-12 Al bonded rear quartz generated. Two were employed simultaneously longitudinal transverse histories free surface. alignment method laser adjust parallelism impactor target also described overcome low power used experiments put forward this paper.
