Gravitational lensing of the microwave background by the intervening dark matter mainly arises from large-angle fluctuations in the projected gravitational potential and hence offers a unique opportunity to study the physics of the dark sector at large scales. Studies with surveys that cover greater than a percent of the sky will require techniques that incorporate the curvature of the sky. We ...

The detection model of sky polarization based on image as a new navigation technology, has a relatively good stability and high research value. In order to improve the accuracy and reliability of the polarization mode measurement and continuous measurement, it constructs a set device of polarized light detection based on image’s real-time synchronous acquisition. Besides, it has carried on the ...

Abstract. All-sky cameras are frequently used to detect cloud cover; however, this work explores the use of these instruments for more complex purpose extracting relative sky radiances. An all-sky camera (SONA202-NF model) with three colour filters narrower than usual kind is configured capture raw images at seven exposure times. A detailed characterization black level, readout noise, hot pixel...

BACKGROUND Surdashan Kriya Yoga (SKY) is a procedure that in various studies, has shown evidences of efficacy in alleviating Depression and Anxiety disorders, but in Europe and USA it has not been studied yet on a Caucasian population as an adjunct therapy for psychiatric Disorders. METHODS The study involved a sample of consenting women and men (n = 69) who received SKY therapy for a six-mon...

The hard x-ray (10-600 keV) sky is inherently time variable and yet has neither been surveyed nor been monitored with a sensitive imaging telescope. The Energetic X-ray Imaging Survey Telescope (EXIST) is a mission concept, proposed for MIDEX, which would conduct the first imaging all-sky hard x-ray survey as well as provide a sensitive all sky monitor (ASM). With ∼60% sky coverage each orbit, ...

We present another explanation for the moon illusion, in which the moon looks larger near the horizon than near the zenith. In our model, the sky is considered a spatially contiguous and geometrically smooth surface. When an object (like the moon) breaks the contiguity of the surface, humans perceive an occlusion of the surface rather than an object appearing through a hole. Binocular vision d...

We propose an outdoor photometric stereo method, which considers environmental lighting for improving the performance of surface normal estimation. In the previous methods, the sky illumination effect has been either assumed to be constant throughout the scene, or to be removed by pre-processing. This paper exploits a sky model which can derive the entire sky luminance from a sky zenith image; ...

Computer graphics recently have began being used for visual environmental assessment or architectural designs. Displaying the sky as a background is indispensable in generating photorealistic images for such applications. In this paper, we propose a fast display method of the sky color by expressing the intensity distribution of the sky using basis functions, even if the sun position and/or the...
