Diurnal variations of hormonal secretion, alertness and cognition in extreme chronotypes under different lighting conditions

Jean-Louis Scartezzini, Mirjam Münch, Apiparn Borisuit, Lenka Maierova

Circadian rhythms in physiology and behavior are modulated by external factors such as light or temperature. We studied whether self-selected office lighting during the habitual waking period had a different impact on alertness, cognitive performance and h ...

Light-driven model for identifying indicators of non-visual health potential in the built environment

María Lovísa Ámundadóttir

This thesis introduces a new approach to characterize and evaluate ocular light exposure based on the discovery of novel blue light-sensitive photoreceptors in the human eye. These photoreceptors are the primary mediators of 'non-visual' responses impactin ...

Daylight Management in Mediterranean Cities: When Shortage Is Not the Issue

Gloria Serra Coch

Natural resources such as daylight and sunlight are highly appreciated in countries with prevailing overcast skies. Taking advantage of this scarce resource contributes to saving energy on artificial lighting. In contrast to northern, southern European cit ...

Implications of the interplay between light and dark for human health in the built environment

Marilyne Andersen, María Lovísa Ámundadóttir

24-hour cycles of light and dark are one of the most significant factors in the built environment that affect human health and wellbeing. In addition to stimulating visual responses, light induces a range of circadian, physiological and behavioral response ...

Development of a Localization System Based on VLC Technique for an Indoor Environment

Kwang Moo Yi

In this paper, we develop an indoor localization device which embeds localization information into indoor light-emitting-diodes (LED) lighting systems. The key idea of our device is the use of the newly proposed "bit stuffing method". Through the use of st ...
