Wayne State University's Dan Zowada Memorial Observatory is a fully robotic 0.5m telescope and imaging system located under the dark skies of New Mexico. The observatory particularly suited to time domain astronomy: observation variable objects, such as tidal disruption events, supernovae, active galactic nuclei. We have developed software suite for image reduction, alignment stacking, calculat...

The MMT all-sky camera is a low-cost, wide-angle imaging system that takes images of the sky every 10 seconds, day and night. It is based on an Adirondack Video Astronomy StellaCam II video camera and utilizes an auto-iris fisheye lens to allow safe operation under all lighting conditions, even direct sunlight. This combined with the antiblooming characteristics of the StellaCam's detector allo...

To casual observers, haze's visible effects on clear daytime skies may seem mundane: significant scattering by tropospheric aerosols visibly (1) reduces the luminance contrast of distant objects and (2) desaturates sky blueness. However, few published measurements of hazy-sky spectra and chromaticities exist to compare with these naked-eye observations. Hyperspectral imaging along sky meridians...

This paper is a study of descriptions foreign conquest the Mesopotamian centre in two Sumerian–Akkadian bilingual texts concerning Tukulti-Ninurta I and Nebuchadnezzar I. Both present these deviant spaces resulting from conquests terms peripheralization centre. Having established similarities presentation topoi texts, then analyses different contexts which are placed to explore how their signif...

The diffuse sky radiation component in the ultraviolet wavelengths is often at least 50% of the global irradiance under clear skies, and is the dominant component of ultraviolet global radiation under translucent overcast skies. The distribution of sky radiance was measured in a rural area and modeled for wavelength bands of ultraviolet-B (UVB, 280-320 nm) and ultraviolet-A (UVA, 320-400 nm). S...
