  Title Influence of Illuminance on Sleep Onset Latency in IoT Based Lighting System Environment. Type Journal Article
  Year 2019 Publication Bioinformatics and Biomedical Engineering Abbreviated Journal (up)  
  Volume 11495 Issue Pages 429-438  
  Keywords Human Health  
  Abstract The exposure to the light has a great influence on human beings in their everyday life. Various lighting sources produce light that reaches the human eye and influences a rhythmic release of melatonin hormone, that is a sleep promoting factor.

Since the development of new technologies provides more control over illuminance, this work uses an IoT based lighting system to set up dim and bright scenarios. A small study has been performed on the influence of illuminance on sleep latency. The system consists of different light bulbs, sensors and a central bridge which are interconnected like a mesh network. Also, a mobile app has been developed, that allows to adjust the lighting in various rooms. With the help of a ferro-electret sensor, like applied in sleep monitoring systems, a subject’s sleep was monitored. The sensor is placed below the mattress and it collects data, which is stored and processed in a cloud or in other alternative locations.

The research was conducted on healthy young subjects after being previously exposed to the preconfigured illuminance for at least three hours before bedtime. The results indicate correlation between sleep onset latency and exposure to different illuminance before bedtime. In a dimmed environment, the subject fell asleep in average 28% faster compared to the brighter environment.

  Title Sustainable Governance of the Urban Night Type Journal Article
  Year 2019 Publication Nauchni trudove Abbreviated Journal (up)  
  Volume 1 Issue Pages 219-233  
  Keywords Planning; Society; Sustainability; Conservation  
  Abstract Since humans are day active primates the differences between day and night seem to be so deeply rooted that a holistic, integrative view of the 24 hours cycle of the city is far from being established. Notwithstanding all the topical talking about the 24/7 city, the analysis of cities and their governance focuses mainly on the day, even if we witness an increasing “colonization of the world after dark” (Melbin, 1987). This extension of activity into the night is producing a growing number of conflicts.

  Title Of husbandry Type Journal Article
  Year 70 Publication Abbreviated Journal (up)  
  Volume Book 9 Issue Pages  
  Keywords Animals  
  Abstract Excerpt from Chapter 14, page 409 in the linked English translation:

...Therefore, at the time when the mallows blossom, when there is the greatest multitude of these butterflies, if a high brazen vessel, with a narrow neck like the mile-column, be placed in the evening among the bee-hives, and some light put down to the bottom of it, the butterflies gather together to it from all places; and, while they flutter about the small flame, they are scorched, because they can neither fly easily upward out of the narrow place, nor, on the other hand, can they retire at a greater distance from the fire, since they are surrounded by the sides of the brazen vessel: therefore they are consumed by the burning heat that is near them...

  Title Two-index model for characterizing site-specific night sky brightness patterns Type Journal Article
  Year 2019 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal (up)  
  Volume 490 Issue 2 Pages 1953-1960  
  Keywords Skyglow  
  Abstract The determination of the all-sky radiance distribution produced by artificial light sources is a computationally demanding task that generally requires intensive calculations. In this paper, we develop an analytical formulation that provides the all-sky radiance distribution produced by an artificial light source as an explicit and analytical function of the observation direction, depending on two single parameters that characterize the overall effects of the atmosphere. One of these parameters is related to the effective attenuation of the light beams, whereas the other accounts for the overall asymmetry of the combined scattering processes in molecules and aerosols. Using this formulation, a wide range of all-sky radiance distributions can be efficiently and accurately calculated in a short time. This substantial reduction in the number of required parameters, in comparison with other approaches that are currently used, is expected to facilitate the development of new applications in the field of light pollution research.
