TL;DR: The context of VLC is outlined, its unique benefits are outlined, and the state of the art research contributions of the assembled papers are described.
Abstract: Visible light communications (VLC) is an emerging field of optical communications that focuses on the part of the electromagnetic spectrum that humans can see. Much existing work in optical communications exists, mainly optimized for capacity and transmission performance in fiber and free-space with biases toward spectrum that minimizes attenuation in the medium. However, the use of the visible spectrum has gained interest due to its availability and the ease at which it can be modulated using light emitting diodes (LEDs). Recent demand factors due to the burgeoning mobile industry and the rapid evolution of LED-based lighting are also driving this interest. Here, and in this special issue, we outline the context of VLC, its unique benefits, and describe the state of the art research contributions of the assembled papers.

TL;DR: In this article, the discovery of seven dwarfs of spectral type L (objects cooler than the latest M dwarfs) in commissioning imaging data taken by the Sloan Digital Sky Survey (SDSS) was described.
Abstract: This paper describes the discovery of seven dwarf objects of spectral type L (objects cooler than the latest M dwarfs) in commissioning imaging data taken by the Sloan Digital Sky Survey (SDSS). Low-resolution spectroscopy shows that they have spectral types from L0 to L8. Comparison of the SDSS and the Two Micron All Sky Survey (2MASS) photometry for several of these objects indicates the presence of significant opacity at optical wavelengths. This comparison also demonstrates the high astrometric accuracy (better than 1'' for these faint sources) of both surveys. The L dwarfs are shown to occupy a distinctive region of color-color space as measured in the SDSS filters, which should enables their identification in a straightforward way. This should lead eventually to a complete sample of many hundreds of these low-mass objects, or about 1 per 15 deg2 to i' ≈ 20, in the complete SDSS data set.

01 Oct 1990TL;DR: In this article, the authors developed an empirical nonlinear stress dependent expression for the deformation modulus of rock masses based on rock mass classification. But the expression was not extended to the case history studies.
Abstract: This paper describes the development of an empirical nonlinear stress dependent expression for the deformation modulus of rock masses based on rock mass classification. The expression defines the deformation modulus as the ratio of the deviator stress at failure to the major principal strain at failure. The Hoek and Brown failure criterion is used to predict the deviator stress at failure. Research was directed toward developing a failure criterion defining the major principal strain at failure. The expression for the deformation modulus was extended to rock mass conditions through correlations with observed deformations from case history studies and predicted deformations from finite element analyses.
