Due to the atmospheric turbulence, the motion trajectory of airborne very high resolution (VHR) synthetic aperture radars (SARs) is inevitably affected, which introduces range-variant range cell migration (RCM) and aperture-dependent azimuth phase error (APE).Both types of errors consequently result in defocused images, as residual range- and apert
A new antenna structure is presented in this paper.The antenna is operating at the Ultra-Wideband (UWB) band, 3.75-4.25 GHz, defined originally in Body Area Networks (BAN) part of IEEE 802.15.6 standard.The antenna size is 89 mm × 60 × 21 mm.The antenna is a directive with a measured Round End Cap gain of 8 dBi at 4 GHz center frequen
The bamboos are underutilized plants with incredible versatility showing amazing healing properties due to the presence of a myriad of phytochemicals including phenols, flavonoids, phytosterols, alkaloids, polysaccharides, glycosides, coumarin lactones, anthraquinones and more.Bamboo shoots and leaves have excellent antioxidant, antibacterial, anti
Traditional debates on analogical thinking, which is at the root of all knowledge about the past, were founded on the scientific-methodological postulate of the striving for increased control of conditions that affect the research situation, that is, the pre-methodological consensus on the need for objectifying, depersonalizing and regulating resea
Compact development and efficient land use are effective ways to address the development dilemma and boost the vitality of shrinking cities.Moreover, it is critical to investigate the relationship between compactness and land-use efficiency in order to healthily Curry Paste and sustainably develop shrinking cities.This study developed an analytical
