Here, a new clutter suppression and small target detection method was presented for nautical radars based on image spectrum filtering and Hough transform (HT).It is well known that sea clutter can be decomposed into texture component (TC) and spiky component (SC).First, the raw echo image was transferred to spectrum field, taking use of the narrow
Physical distancing, as a measure to contain the spreading of Covid-19, is defining a "new normal".Unless belonging to a family, pedestrians in shared spaces are asked to observe a minimal (country-dependent) pairwise distance.Coherently, managers of public spaces may be tasked with the enforcement or monitoring of this constraint.As privacy-respec
Climate change leads to novel species interactions and continues to reshuffle ecological la rams crop top communities, which significantly declines carbon accumulation rates in mature forests.Still, little is known about the potential influence of multiple global change factors on long-term biomass dynamics and functional trait combinations.We used
In this study, we present improved fusion-bonding strength results between carbon fiber-reinforced polyetheretherketone (CFR-PEEK) and zinc-coated steel through the introduction of pre-inscribed laser surface patterns.Optimized laser welding parameters, including laser power, focal position, final audio sonorous vi pitch, number of passes, and clam
Dear Editor: Undocumented immigrant American workers face barriers to adequate safety training and disparities in occupational health.1 The workplace plays a vital role in the lives of all Americans who perform the necessary work that keeps society functioning, including undocumented workers.It is important that workers receive training and educati
