Hierarchical architecture and core–shell configuration synergistically endowed waxberry-like Ni@C microspheres with an upgraded microwave absorption performance.
The effects of the water-binder ratio and different graphene oxide (GO) sizes on mechanical properties GO-cement composites were systematically studied by preparing mortars. scanning electron microscopy observation (SEM) surface fracture cement pastes was carried out to study morphology hydration crystals in systems under space conditions. It found that GO nanosheets significantly improved compressive, flexural, tensile strengths When dosage 0.03% weight cement, at 28 days increased 21.37%,...
Optical coherence tomography (OCT) is based on detection of interferometric signals and hence inevitably suffers from speckle noise. To remove noise in OCT images, wavelet domain thresholding has demonstrated significant advantages suppressing magnitude while preserving image sharpness. However, images different characteristics spatial scales, which not been considered previous applications thresholding. In this study, we demonstrate a adaptive (NAWT) algorithm that exploits the difference...

Moving target indication (MTI) in bistatic synthetic aperture radar (BiSAR) is a promising task both civilian and military fields. However, it suffers severe challenges under the influence of clutter. MTI BiSAR mainly faces three challenges: 1) range cell migration (RCM) larger than that monostatic radar; 2) clutter range-Doppler spectrum severely extended; 3) characteristic closely related to geometrical configuration, with nonhomogeneity nonstationarity. To solve these problems, based on...
Sea clutter suppression plays a crucial role in maritime moving target indication. However, the bistatic SAR (BiSAR) system, traditional space-time adaptive processing (STAP) method can't satisfy expected performance due to severe range cell migration (RCM), Doppler frequency (DFM), nonstationary clutter, and spatio-temporal spectrum expansion caused by internal motion of sea clutter. STAP based on sparse recovery (SR-STAP) is an effective for suppression, but two major problems still...
In the field of pipeline inner wall inspection, snake robot demonstrates significant advantages over other inspection methods. While a simple traveling wave or meandering motion will suffice for inspecting small-diameter pipes, comprehensively and meticulously large-diameter pipes requires to adopt helical gait that closely adheres wall. Our review existing literature indicates most research development on robots has focused outer surface cylinders, with very few studies dedicated developing...
