In performing surveillance using a sensor network, data association and registration are two essential processes which associate from different sensors align them in common coordinate system. While these usually addressed separately, they actually affect each other. That is, requires correctly associated data, with biases will result wrong association. We present novel joint association, registration, fusion approach for multisensor surveillance. order to perform together, the...

Both image registration and fusion can be formulated as estimation problems. Instead of estimating the parameters true scene separately in conventional way, we propose a maximum likelihood approach for joint this paper. More precisely, performance is used criteria to evaluate accuracy. Hence, automatically tuned so that both optimized simultaneously. The expectation maximization algorithm employed solve optimization problem. Cramer-Rao bound (CRB) then derived. Our experiments use several...

Abstract Maxillofacial bone defects exhibit intricate anatomy and irregular morphology, presenting challenges for effective treatment. This study aimed to address these by developing an injectable bioactive composite microsphere, termed D‐P‐Ak (polydopamine‐PLGA‐akermanite), designed fit within the defect site while minimizing injury. The microspheres biodegraded gradually, releasing calcium, magnesium, silicon ions, which, notably, not only directly stimulated osteogenic differentiation of...

Nanoplastics represent a global environmental concern due to their ubiquitous presence and potential adverse impacts on public health. There is growing need advance the mechanistic understanding of reactivity as they interact with biological systems.

The dependent temperature pH, maximum at pH 4.5 40 °C. catalytic exhibits saturation kinetics,...

Wireless sensor network (WSN) is considered here for remote monitoring of mine tunnels. Since transport and exploiting plane are the complex tasks that require video monitoring, a major challenge tunnel multipath diffraction effect due to unreliable channel limited capacity. We propose braided cooperative reliable (BCRT) algorithm transmission within tunnel. BCRT maintains one-hop reliability ensure end-to-end so it robust path breaks. In addition, BCRT-based WSN uses three consecutive...

In cooperative spectrum sensing (CSS), an optimal decision fusion rule can effectively improve the performance of secondary system.

In a cognitive sensor network (CSN), selfish sensors can choose to conduct cooperative spectrum sensing (CSS) or local (LSS). CSS usually improves performance at the price of delay and energy consumption.

The current public switched telephone network (PSTN) is only able to deliver analog signals in a relatively narrow frequency band, about 200-3500 Hz. Such limited bandwidth causes the typical sound of narrowband speech. In order improve intelligibility and perceived quality speech, we propose using data hiding extend PSTN channel bandwidth. Based on perceptual masking principle, inaudible spectrum components within can be removed without degrading speech quality, providing hidden transmit...
