Non-circular features in Saturn’s D ring: D68
D68 is a narrow ringlet located only 67,627 km (1.12 planetary radii) from Saturn’s spin axis. Images of this ringlet obtained by the Cassini spacecraft reveal that this ringlet exhibits persistent longitudinal brightness variations and a substantial eccentricity (ae 1⁄4 25 1 km). By comparing observations made at different times, we confirm that the brightness variations revolve around the pla...
متن کاملfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولKinematic Models of Non-circular Features in Saturn’s Rings
Using high-resolution movie frames and azimuthal imaging scans with radial scales as fine as a few km and longitudinal resolutions as fine as a fraction of a degree, we examine the shapes and kinematics of the B-ring outer edge and the Huygens ringlet. The former is known to be strongly influenced by its proximity to the 2:1 inner Lindblad resonance with Mimas [1,2]; the latter has been suspect...
متن کاملTransmittance of MIM Waveguides Containing Semi-Circular Ring Shaped and Rectangular Ring Shaped Grooves
In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...
متن کاملMultilayer Circularly Polarized Circular Annular Ring Patch
This paper presents the effect on circular polarization of multilayer circular annular ring patch (CARP). A CARP have been fabricated on FR4 substrate of dielectric constant 4.2 and thickness 1.52mm. Experimental resonant frequency impedance bandwidth and Axial ratio of simple CARP, covered CARP, spaced dielectric CARP and CARP with two superstrates have been measured and simulated using full w...
