The purpose of this paper is to study the optimal scale factor on the central meridian in order to minimize distortions of the 2掳Transverse Mercator map projection in TWD97. The optimal scale factor is first derived according to the Airy optimal theory of distortions. Next, the influences of...

but was lowest at the horizontal and vertical meridians (Fig.5A, orange), similar to the deviation from cardinal (Fig.5A, green). Confirming this observation, deviation from radial was linearly correlated with angular distance from the closest meridian (r = 0.141,p < 10−38). Howe...
This study adopted the amplification factor (ratio of response spectra between soil and outcropping rock) of rock types to understand the site classification map. As this study implemented the Vs30 information at bedrock level, PGA was esti- mated as an earthquake hazard. For moderate earthquakes,...
Figures13and S12 show the regression intercepts and regression coefficients of the boreal summer and winter MJO against the IOD. Although the amplitude of the regression coefficients with respect to IOD is larger than that obtained with respect to ENSO (typically by a factor of 2 from Figs.11,...
(about a factor 2) increase of plasma pressure ahead of the dipolarization front near its stopping point (Yang et al.2011; Birn and Hesse2013), which impacts on the pressure distribution across the magnetotail as well as the supporting field-aligned currents (Shiokawa et al.1998). Supporting...
which at this frequency add less than 10%in brightness (Hanel et al. 1981). The calibrations on Jupiter and Saturn are consistent in channels 1( 3) and 4. In channel 2, Saturn is dimmer than we expected by a factor of two. In addition( the o)set in channel 2 drifts downward by ...
From (52), we see that the local linear scale factor will be equal to 1 for 𝑙=0l=0. Therefore, the central meridian of the mapping area is the standard meridian. Figure 5. The world on a transverse Mercator projection of the Earth’s sphere, with 10° graticule and Tissot’s ...

Remote-sensing investigations involving empirical ARC approaches, that are based upon the use of a scaling factor, do not usually account for the orbital dynamics that govern temporal changes in the Earth-Sun distance and variations in the solar zenith angle spatially (i.e., small-angle approximat...
