Mirrors in the Burial Rites of Saryarka Population in the Golden Horde Period
Поволжская археология, 2017 The authors analyze the mirrors which were originally discovered in ancient Turkic burials, but became widely spread as late as in the Golden Horde period, which was largely accounted for by the intensification of contacts due to the establishment of the

Performance improvement of two-axis solar tracking system by using flat-mirror reflectors
Energy Reports, 2020 This work studied the performance improvement of a two-axis solar tracking system by using flat-mirror reflectors. The two- and four-sided flat-mirror reflectors were set on the solar panel with angles of 90°, 120°, and 150° between the panel and flat ...

Rugged optical mirrors for Fourier transform spectrometers operated in harsh environments [PDF]
Atmospheric Measurement Techniques, 2016 The Total Carbon Column Observing Network (TCCON) and the Network for the Detection of Atmospheric Composition Change (NDACC) operate a number of Fourier transform spectrometers (FTSs) that measure trace gases in the atmosphere by observing solar spectra.

Plasma cleaning of ITER first mirrors in magnetic field
, 2014 To avoid reflectivity losses in ITER optical diagnostic systems, plasma sputtering of metallic First Mirrors is foreseen in order to remove deposits coming from the main wall (mainly beryllium and tungsten). Therefore plasma cleaning has to work on large

The Casimir force for passive mirrors [PDF]
, 1997 We show that the Casimir force between mirrors with arbitrary frequency dependent reflectivities obeys bounds due to causality and passivity properties. The force is always smaller than the Casimir force between two perfectly reflecting mirrors.

A proposal for (0,2) mirrors of toric varieties
, 2017 In this paper we propose (0,2) mirrors for general Fano toric varieties with special tangent bundle deformations, corresponding to subsets of toric deformations.

Nursery World, 2017 Like with so many other everyday things that become extensions of ourselves, we experience the mirror—in that look and see moment—routinely and habitually. With unfaltering precision the mirror captures my face, immediately copying it back for me to examine.
