A simple Google Maps area calculator tool that allows you to click multiple points to measure the area of any plot of land, rooftop, or even a state border!
The reader should note that we are assuming that most pixels in a single field boundary share a common crop type label and based on this assumption, majority filter is used to refine the crop classification maps so that a single field boundary is labelled with the crop type which has the ...
1). The size of each experiment plot was 40 m2, the soil texture was predominantly sandy loam and sandy clay loam, as determined by textural analysis of soil samples collected before planting. Maize cultivar Dedan-5 was used in the experiment, which was planted on June 12, 2019, and June...
Paleogeographic maps of the Late Ordovician in the Central China region and their explanation. J. Stratigr. 5, 165–170 (1981). Google Scholar Wang, L. S. et al. Geochemical evidence of shale gas existed in the Lower Paleozoic Sichuan basin (in Chinese with English abstract). Nat. Gas...
(20 nm/80 nm) contacts were evaporated onto the wafer to form source and drain contacts with the aid of a shadow mask. The wafer was then diced into individual 1.1 × 1.1 cm2devices, and the devices were then mounted on a printed circuit board (PCB) with two part ...
To characterize brain activation responding to the two types of videos, one sample T-tests on the beta maps of the block regressors were conducted at the group level with gender and age as covariates. To further identify brain activation modulated by PV, a whole-brain voxel-wise paired T-tes...
(DT) of ten black segments and six hospital hubs; b a Gabriel graph showing eight red segments, balance points (in blue), and intersection points (in pink); c a plot of the perpendiculars (in yellow) and the expert assessment for three intersection points inside circles; d the estimated ...
For reference, we also plot the first ionization threshold of carbon assuming the field ionization by laser24. The carbon ionization potential is obtained from the NIST Atomic Spectra Database25, and is plotted against charge state in Fig. 5b by converting the threshold intensities under assumption...
Figure 5f plots the maximum intensity plot as a function of the lens NA. For optimized lenses with NA > 0.44, we see improvements of more than 25%, with a maximum improvement of 53% for the NA = 0.9 lens. The experimentally determined intensity integral, which is analogous to the ...
